If you've taken your Yaris on a Dyno, post the results here, along with a list of relevant mods :smile:

To start off, here's one by staticorex, bone stock.

[Masteraal]

5400-6100 not much difference in power output lol

[cali yaris]

Here is mine with intake, header, pulleys and axle-back exhaust:

And here is mine with the turbo set up on stock motor @ 8psi,
along with a different pull from the dyno session shown before:

[cleong]

Here's mine:

DC Header, Fujitsubo Exhaust, Denso Iridium Spark Plugs, 5W40 Shell Helix Oil. Otherwise everything is as standard factory delivered.

Numbers on the chart are at the crank. WHP is roughly 102.75 and torque is 130Nm (95.8ft/lb).
EDIT: Thanks for pointing out the unit difference for torque; I have added the lb/ft conversion.

http://eaglet.org/albums/Yaris/dyno_chart.jpg

[taKuto]

that's because yours is measured in Nm :P everyone else is ft-lbs.
not a yaris but same engine anyways, only mods are intake and muffler replaced with a small resonator.
edit: manual transmission, did all runs in 4th gear

[Yoda]

this will be a very useful thread
+1

[cali yaris]

cleong, you're hp and torque don't cross at 5250 -- sup with that?

also, wouldn't the rev limiter kick in at 6250?
Or do you not have the same limit as we do in USDM?

[at3GG]

Is it all dynos charts that should cross at 5250...or is that just a correct setup for our engines?

I posted this chart before the Big Crash and someone explained its because the scale between HP and torque is different.

Your NA dyno chart seems to go to 6500rpm too. But redline's 6500rpm on my dashboard, I think. I'll need to run out and check it later.

[LtNoogie]

Had to straight-line interpolate where the sensor had a bad connection.

Not as good as I had hoped. This was my baseline before the supercharger install.

[richardholdener]

HP and tq are alwasy equal at 5252 rpm. The reaosn they don't cross on the graph is that the two scales are different. If both HP and NM (converted to tq) scales went from 0-160, then they would cross at 5252. Here is the 120-hp graph supplied previously before the hack. Mods were custom intake manifold, CAI, Xd tb, synthetic oil and off-road down pipe with no exhaust. Is it all dynos charts that should cross at 5250...or is that just a correct setup for our engines?

[Treyz]

Now are these all with manual transmissions?

[eTiMaGo]

I would think so yeah... I have seen local dynos of stock AT's here doing about 80whp only...

[Treyz]

Yeah .. I got the Yaris purposely as a daily driver since I had my 240SX track/weekend driver so bought it in an atomatic.

Man am I kicking myself in the ass now after I got rid of the NIssan and started modifying the Yaris.

[cleong]

LtNoogie's got an automatic. I think the rest are all manual transmissions.

[richardholdener]

Here is a graph of our recent test using a CAI (actually flipped over stock filter lid), the new intake manifold, long-tube header and 2.25-inch exhaust, NST u-pulleys & Xd Tb. Might be more with additional tuning once FIC arrives from AEM for testing.

[blacksandiegovitz]

Very impressive numbers with that NA set-up. More power than with the blitz supercharger kit , Very nice, I hope to make about the same as I'll be running the longtube header with the intake manifold.

[eTiMaGo]

I, for one, can't wait to see Garm dyno his beast with the new intake manifold :biggrin:

[at3GG]

^^^:drool:

[whooppee777]

the first graph is of staticorex (im assuming by the name of the file) his yaris is an automatic sedan. he has a blitz supercharger now he had his yaris dynoed after the install of the supercharger i've seen it in person cant remember the numbers though. i wanna say close to 130 with the blitz supercharger

[PETERPOOP]

Very impressive numbers with that NA set-up. More power than with the blitz supercharger kit , Very nice, I hope to make about the same as I'll be running the longtube header with the intake manifold.


Actually with the blitz S/C kit and pulleys,exhaust,CAI, etc... it's been recorded to put down 130whp.

But I am with you. I am on his manifold list and possibly his long tube header list. I might run those for a year or two until a legit company comes out with a turbo kit for the yaris.

[1nz]

Sedan, Auto trans, both with trust airinx intake kit, from 98.4whp-101.6whp

When this car was just 15000km and just installed the trust with non branded, noisy aftermarket exhaust i got 102.8whp but this maybe because spark plug, intake and temperature which caused me to luse the 1.2whp hehe

http://i60.servimg.com/u/f60/12/70/12/78/torque10.jpg

[cleong]

The dyno sheet looks like it only has torque and AFR overlay, HP graph doesn't seem to be there?

What mods have you made to the car to get 101whp?

[LtNoogie]

Before: Max HP - 90.5 hp.... Max Torque - 88.6 ft-lb
After : Max HP - 117 hp..... Max Torque - 114 ft-lb

I'm also running too lean. The only other change besides the supercharger was that in the before run, I had the TRD CAI. I swapped that out for the aFe Intake for the after run.

The butt dyno says it feels like I have more power but the the bull stops with the charts.

Those of you in the Los Angeles area looking to see how much power your car really puts out should go see Harry at HK MotorSports. He also tunes cars for a living so if you get a turbo kit, perhaps he can help.

[PETERPOOP]

wow only 117 with full NST pulley set, blitz S/C, afe intake, megan header,AND trd exhaust.... how the heck did that other guy put down 130whp?

[LtNoogie]

I guess my slushbox is slushing all my power away. You guys with the manual transmissions have all the fun.

Actually, I'm not complaining because when I push hard on the pedal, the car just takes off like a monster was just let loose, and immediately. I don't know if the additional low-end torque is what's giving me better acceleration or what. I almost never go beyond 4,000 rpm so the max HP is something I'll never feel.

[PETERPOOP]

Well a 27hp gain isn't bad, i was just expecting more (after hearing about 130whp from the other blitz owner).

[thebarber]

Well a 27hp gain isn't bad, i was just expecting more (after hearing about 130whp from the other blitz owner).
its the auto thats limiting his at-wheel HP

a manual with similar mods would run about 135whp

the only nst pulley that will yield wheel horsepower is the underdrive crank pulley.

the other items he has are good, but if he replaces the resonator to axle exhaust section im sure he'd gain a few more ponies

117 is very respectable for a s/c'd auto

well done LT

[cleong]

Phwoar, a slushbox wastes nearly 13-18hp compared to a stick? That's gotta hurt!

[LtNoogie]

Phwoar, a slushbox wastes nearly 13-18hp compared to a stick? That's gotta hurt!

It actually doesn't hurt that bad. Numbers and charts are abstract. My butt dyno knows the difference when I have the S/C running and when I don't. Since I don't have a MT, I don't have a frame of reference as to what I'm missing. Ignorance can be bliss. :thumbsup:

http://i60.servimg.com/u/f60/12/70/12/78/power10.jpg
just a trust intake, lukey exhaust and denso iridium spark plugs

[PETERPOOP]

no blitz (even with all the mods noogie has) on a manual has been dyno'd at 135whp so far. just 130whp.

[whiteghetto]

do we have a comparison of automatic 1.5, stock everything
CAI vs SRI?

[PETERPOOP]

http://i416.photobucket.com/albums/pp250/tropicalsuckerpunch/_DSC9599.jpg

Done on a DynaPack dyno.

89.9whp

95.7 lbs of torque

MODS: octane 87. aFe intake, NST underdrive/wt/alt pulleys, blitz axleback, royal purple.

[thebarber]

peter, why didnt they run your car to redline....you'd have made more power...

[PETERPOOP]

Because I don't know what the redline is. I told him 6100-6200rpms. It already sounded like the engine was going to blow up when i was next to the car. All the other dynos on this thread seem like their power peaks at 6k and dies after that. I don't think it would have made more power.

[LtNoogie]

What hp reading were you hoping for? I was hoping to do better than 90 hp for the "before" dyno pulls. I sure expected more than 117 hp for the "after" dyno pulls. It's sobering but I'm glad you did it. Congratulations.

[PETERPOOP]

Thanks. I was hoping for ATLEAST 90whp. I probably would have had it if i was running 91, had a header, and it was cooler here in hawaii.

I am hoping for some big gains once I put everything on!

Completely stock dyno at @56k miles. Only oil changes and one filter change at 30k.

http://i42.tinypic.com/jt5ohj.jpg

With 20% correction, it was 105.5 hp. The engine has held up very well! Thai said with new plugs and air filter, it would easily gain a few hp too.

Nice video. Those dyno guys should have let your engine bay cool off a little between runs. And yes, that seems really rich.

Hi guys,
This is my Dyno chart at 0.8 bar of boost , I have made the test in a very hot day 30°C (86°F) with 65% humidity also I have also tuned with 0.9 bar of boost and the results are 206 hp and 239.6 Nm torque

No way that there is a 20% on that last sheet for a stock Yaris. For crank yes but not wheel so it is correct in terms of wheel hp being at 88whp.

[Treyz]

Decided to attend a Dyno/BBQ day at Perfromance Motorsports today.

They dynoed a Nissan Cube (stock from the dealership directly being they are apart of Smitown Nissan) so I wanted to see if I could beat it ...

Only power mod is the AFE intake and ground wiring kit ... also with the ol' a/t slush box ...

^ nice man, bet that was fun.

I have also tuned with 18 psi of boost and the results are 206 hp and 239.6 Nm torque

18 psi yielded 206 hp? That seems very very low for that much boost. Is it a typo?

[Treyz]

lol you confused me a bit Garm.

[changchewsoon]

193 ps and 275 nm at the wheels @ 16 psi

detailed information of the mod can be found here (http://viosturbo.blogspot.com/2009/05/200-whp-toyota-vios.html)

How are you guys managing the boost out there? We need those Ancient Asian secrets here in the US!!!

[changchewsoon]

errrr, tell me what you guys need to know? i'll try my best to share as much information as possible.

[Giupo]

The Greddy turbo is very small..

[m911gt]

The scan didn't come out as clear as I wanted it to but here are two of my runs at my university's Mustang dyno. The second run yielded 103 whp and 103 ft-lbs of torque. Relevant mods include the lightweight pulleys from NST, an AFE Stage 2 intake, a Thunder Sport header, and a Tanabe Medallion Touring exhaust. All pulls were done in fourth gear and my car has a manual transmission.

[mikenacarato]

here is mine from this weekend, pulleys, intake, corolla tb
royal purple oil and 89 octane were used.

To tell the truth i dont even feel a diff lol. Gonna get it dynoed again since i just did the TB upgrade. People say they feel the power i says:iono: my butt dyno dont feel nothing:thumbdown: No cel no oscillation just a low idle of 500 rpm when warmed up good.

Ok TB dyno posted

[2bad4u]

The dyno result for 06 Vitz RS 5spd. only mod are a BroSpeed Bosal axle-back muffler and grounding kit (home made).
Max Power = 101.13 Max Torque 93.44

Was your 06 Vitz RS a manual, or a CVT?

[mikenacarato]

it says 5 spd

[2bad4u]

yes 5 spd

I wanted to do the dyno now for on Sunday I will start more mods all coming in from S. Florida my wife went up for a few days. I got must from Garm and a few more from sellers on YW. Hope for about 10 - 15whp more. then in a month or two a s/c or turbo but leaning more to a Blitz s/c

The dyno chart seems to suggest that the JDM Vitz RS has the same output as a regular 1.5 litre Yaris, reinforcing what the factory dyno charts show.

I think the Vitz RS TRD would be a bit more in hp and tq though.

[changchewsoon]

no change in boost, plug and play coils.

custom intake, 1zzfe throttle body, megan fart can, NST underdrive crank pulley

OK, got some hard data for y'all. Frownonfun and I both did a dyno day this morning, and the conditions were nice. We did this on a Mustang AWD dyno, so the tech told us we're probably a few percent higher than this dyno shows, but close enough.

I'll post the scans of the sheets later.

OZMDD - 107 WHP / 106 TQ, AFR -12.6. Also, 76 deg F air temp (at the intake, according to the SGII) [TRD CAI w/ bypass fitting removed and replaced with coupler, Thunder axle-back exhaust, NST 10% UD Lyte pulley.]

FROWNONFUN had 145 WHP from the S/C setup we installed a few weeks ago, and that's with stock tuning (piggyback) and no other mods besides axle-back and NST Alt pulley!! I believe that's around 6 lbs boost. :respekt:

[cali yaris]

nice! :clap: looking forward to the graphs

[lilredrocket]

ozmdd that alt pulley cam with the s/c so you can run the belt for the s/c. I believe frownonfun's afr was around 11.3 and the guys running the dyno did the math and said the HP number should be around 147-150hp and no CEL's

[thebarber]

145whp is impressive on the rotrex

i still want dyno charts though!

[PETERPOOP]

niceeeeee! i'm jealous

i knew it had more power than the blitz when i saw the video of it taking off with a passenger inside. can't you put an intercooler on that kit too and get an advertised 150whp with it. Since he's getting 145whp as of now, that intercooler could maybe take him to 155 + whp. I believe the kit only advertised that it puts down 140whp; so you already have a good thing going!

Now get a headerback exhaust setup. ;)

[lilredrocket]

He has a custom axle back. but thats it for exhaust when I was talking with him today and tole him he needs to get a header and showed him where he could cut for to put in an intercooler. Also this kit can be used with the intake mani that Garm is developing. I also told him that after he gets an intercooler he could talk to Mike at NST and have him make a smaller pulley to get some more boost out of the kit. The guy also just bought some 2zz injectors just to be on the safe side.

[lilredrocket]

Hey Peter one of the first times I went to Mike's shop I was talking with him about the Blitz kit and if he could make a pulley for the kit and he said he had a few options and after looking around some he ruled out one of them.

1.) make an overdrive pulley for the crank (ruled out pulley would be to close to another)

2.) make a fixed pulley for the blitz and probably through a cel and take away the option of turning the s/c off and on.

3.) make a clutched pulley and and still be able to run the s/c like normal. I think he said he could do this for about $500 or so price but worth it if you want to use you the on/off function

Hey i've explored all these options. I messaged NST about making an overdrive crank pulley with a smaller water pump pulley (that is the pulley your friend is talking about). NST sounded grateful for the information, but I doubt they will develop anything. :thumbdown:

2. Garm is looking into making a smaller fixed pulley without the option of turning on/off

3. Yah, this is the most expensive option, however might be worth it. PM me more about that..

[lilredrocket]

Just ask Mike at NST. He also makes one off pulleys that why they are so much too. The reason they won't develpoe it is because there is not a big enough market for it you know?

to be fair i also have a kyle busch license plate frame for my back plate. could account for the extra hp.


also i'll put an intercooler in when garm finishes that hood from the contest. and if garm still has a few dc sports headers in stock on friday i'll be picking one of those up too.

.....

I am aware of this and I ALREADY have spoken to him. The overdrive crank pulley and smaller water pulley would have been custom made for me and I would have paid for the expense to make them. However, he seems to not want the business, so screw it. So why bother him with a clutch pulley when he won't make me the overdrive crank and smaller water pulley. Know what i'm saying?

[lilredrocket]

I'm sure if you seemed really interested he would make them for you call him and ask no harm in asking again

[Sabretooth]

Well if everyone on board with the Blitz kits would want one, I asssume the price would come down if he was able to make 5-10 pulleys and sell them over time instead of 1 piece.

Guys... nothing wrong with either of your comments, but maybe start a thread for it? the dyno charts are kinda getting lost among the debate. :smile:

[lilredrocket]

WRONG. lol

Yes. Mike and I are both aware of this. I would fork out the dough to pay for the custom made pulleys and let him know if everything worked out. I would dyno my car and show the results and would provide the info on how much more lbs of boost I am getting. If everything was good, he would probably make a TWO-pulley supercharger set (overdrive crankpulley/smaller waterpump pulley) and sell them as that. He could make some decent money off of that and I am sure a lot of blitz owners would purchase it. However, he does not seem interested in making me the overdrive crank pulley/smaller water pump pulley anymore (like i've already stated in this thread) and the project is in the can.

[lilredrocket]

Why are you stuck on an overdrive crank pulley? Why not an underdrive s/c pulley? Did he say he was not interested? He told me that he would need someone witht the s/c there to do some testing and such. Why dont you start up a GI thread for it to show Mike how many people are interested in it? He is a busy guy why not try and help him out?

[PETERPOOP]

So I can keep my on/off function? He said he was interested and would do it for me. He did not say anything about needing someone with a blitz kit there to be able to make the pulley. Him making me the pulleys DID NOT require a GI thread, since I would be paying whatever cost was needed to make MY pulleys (for the 1000x). lmao.

You just don't stop, do you?

It's really funny how you want this and don't do any follow up on it.

[PETERPOOP]

It's really funny how you have no idea what you're talking about.

[ozmdd]

OK, here it is:

I know the numbers are pretty faint, but the scale on the left is HP and Torque, with an increment of 15, starting at 50, up to 200.

Edit: Actually, totally unreadable once posted. I'll have to do a greyscale scan and repost.

Still, it says: Max Torque (ft-lbs) 106 (@4000rpm)
Max HP - 107 (@5900rpm)
Max AFR - 12.6 (@3300rpm)

HP and TQ cross-over at 5200rpm, right around 105 each.

The torque curve is the middle one (blue), and is remarkably flat. :)

Nice! Looks like we've identified the benchmark hp/tq for the NA Yaris: better breathing. Your numbers are just a flip=flop of mine. Gotta love that flat torque curve. Are you running the stock crank pulley?

BTW - what brand of dyno?

only mods were intake and res-back exhaust...everything else is stock

[talcum]

Hey barber,
What kind of res back exhaust? You got 5 or 6 hp out of it. Is it really, really loud?

Thanks,

Finally got my dyno sheet. Here are the two highest numbers from the two different days.

The 140whp/135tq number is without the custom overdrive pulley.
The 136 whp/140 tq number IS with the pulley.
Decrease in overall whp, but a gain in torque.
As you can see, with the pulley on, it pulls stronger all across the board.

Anyone seen the sedan 1nz-fe automatic dyno?

[changchewsoon]

Dyno chart of a Vios on a turbo kit, and later on with an upgraded ball bearing turbo.

Engine is stock, and automatic transmission is stock as well. The missing gap in the dyno chart was caused by the Okada Project coils interfering with the Dynojet's RPM reading.

More information can be found here (http://www.viosturbo.com/2010/08/gt-auto-stage-1-special-turbo-kit.html).

[eTiMaGo]

200hp? niiiiice!

[YotaYaris]

WOW, 29% increase in HP, and 24% incrase in TQ..........
So the only chang between the first and second graph is the new turbo?
Why the different redline?
Also, was it done on the same dyno?
Thanks

[changchewsoon]

Yup it was done on the same dyno, pretty amazing considering the engine is still stock and its running on an automatic transmission.

well, i gave the yaris its final hurrah today

took it to forrest and forrest racing in ayr to run it on the dyno.

i ended up pulling 136whp and 130wtq

old pull was with intake and res-back exhaust (106whp/107wtq)

new pull was with same intake and res-back exhaust as well as dc header, blitz supercharger, 1zz injectors, colder iridium plugs (136.2whp and 129.8wtq)

im pretty happy with that.

[changchewsoon]

Tuner did a conservative base tune to run in the engine

[cali yaris]

^ Amazing. :bow: What's your boost?

But -- Power and torque don't cross until 7000? That's not quite right.

[changchewsoon]

Hi Garm,

That's because of 2 reasons:

1. The torque measurement is calculated using kg-m instead of ft-lbs
2. I didn't apply force scaling

Now they should be crossing after I've updated the torque measurement to ft-lbs and applied force scaling.

I'm running 23 psi of boost at the moment.

[cali yaris]

That short runner intake manifold sure helps with the top end power, she wants to make power through redline - that's great!

What is your exhaust manifold design? I'm redesigning mine to try and regain some of that lost torque from the intake side.

and -- what fuel are you using for these numbers?

[thebarber]

Zoiks!

[changchewsoon]

Hi garm, I am currently using Golden Eagle's intake manifold, however when they designed it for me it was still a prototype model.

I've yet to feedback to Bob Woodcock about it. I think I shall do it soon.

I am running on pump gas at the moment. Can't afford to use race fuel and drive around town to run in the engine, think I will break a big hole in my bank account if I do so :(

[malibuguy]

Fucking nuts

[malibuguy]

Like crap?

[1.5]

Thats a shop here in Tampa. Are you sure that is for the 1nz?

[Golddeenoh]

this stuff is more exciting that porn! i want 400hp yaris! power to weight would leave mustangs and camaros in the dust.

[changchewsoon]

After running in the engine, I had the car sent back for a tune today and things got interesting.

Blue curve - 404 whp, previous base tuning for engine run in, pump gas, 1.6 bar boost, no water/meth.

Red curve - 454 whp, pump gas, 1.7 bar boost, water/meth turned on.

Green curve - 501 whp, pump gas + avgas 50/50 mixture, 2.2 bar, no water/meth.

[cali yaris]

That's crazy - CONGRATS on pushing the 1NZ to the new record power levels. 2.2 bar is about 30 psi, right?

Any idea why the power is so much higher than the torque? The gap between the two seems to grow the higher you go with boost and power.

Any videos of a pull? I bet it sounds great at 8000 rpm.

[changchewsoon]

Hi Garm, I am currently uploading the video to YouTube at the moment.

Not sure why the torque curve is like this, maybe the 1NZ engine is not meant to produce a lot of torque?

But we do know that the power is still climbing at 8000 RPM. Not sure how it'll go if we give it another 1000 RPM.

[eTiMaGo]

wowowowowowowow crazy good stuff!

[ilikerice]

holy shit balls batman!

and the winner goes tooo

Holy batman robin n iron man ...

500 plus on a Yaris ... Even on my AMG with double the Yaris weight I get scared sometimes with the traction control off ....

[Golddeenoh]

holy sheeeet 32psi. big boost there big pimpin.

[cali yaris]

holy Avengers...

what's "avgas"? some kind of race gas, I'm guessing?

[changchewsoon]

We call them avgas on our part of the world, perhaps it's better known as aviation fuel on your side?

[Golddeenoh]

ahh we tend to call it "Jet Fuel" and depending on the grade maybe even "Race Fuel" or "Race Gas".

[thebarber]

Any idea why the power is so much higher than the torque? The gap between the two seems to grow the higher you go with boost and power.

I'm guessing turbo choice...

And HP = (tq x rpm) / 5252....so at high rpm you need less tq for big hp

[cali yaris]

I don't see how he could have much more than a GT30 back there.

[thebarber]

455whp at 8300rpm = 288wtq at 8300rpm

501whp at 8300rpm = 317wtq at 8300rpm

When peak HP is at such high rpm, you don't need to make a ton of tq up high (relative to HP, that is)

My vibe's 2zzge is 180hp at like 7600rpm and 130tq at 6800rpm...

[Hussain-Vtec]

After running in the engine, I had the car sent back for a tune today and things got interesting.

I just ran the car as it was. However, I did disconnect the battery after putting on the short ram intake so that the ECU had plenty of runing time to readjust to the new operating conditions.

After the first one, he asked if I wanted third gear pulls, but I wanted all the pulls to be done under exactly the same conditions to get consistent results.

I was always under the impression that 4th gear pulls were standard for dyno. Not sure why though.

Maybe it's because 4th is usually 1 to 1 gearing like BEEF said. It just was so funny how long it took to wind up because the little engine doesn't make much power.

[1.5]

lol yeah did you have to pay the tech overtime so he could finish the pull lol

[cali yaris]

1 to 1 is the most accurate, and the pull is long enough to record with precision -- in tooter's case, great precision. :laugh:

The pull above on mine was to 7300 rpm, 1000 over where the stock limiter kicks in.

Yeah, the engine was still trying to hit redline when Harry told the guys to close up the shop and go home... he'd stay overnight hoping the run would be done by sunup. :laugh:

[cali yaris]

you're funny, tooter :laugh:

[why?]

Tooter, some pulleys and lightweight wheels would make that less painful, and add a couple hp to get over 100 as well.

[tooter]

There's no pain in getting an honest accurate measurement of the power that the engine actually produces. :smile: The point isn't to enhance the results but to obtain two relative results where the intake manifold is the only change.

And that heavy pully on the front does serve a purpose. They used to be called harmonic balancers. The flywheel weight on the front helps to minimize the twisting forces exerted on the crankshaft by the flywheel weight on the rear.

I visited the CNC guys today and we went over details and clearances using the 3D image generation of the flange. The intake manifold flange will have a small 3mm deep inset where the runners of the manifold can be inserted to hold them in proper position while they're being welded on. The thickness of the shelf will match the thickness of the runner tubing so that the interior remains uniform. Any slight imperfections I can smooth out from the inside with a Dremel. The computer automatically generates a seamless transition within the one inch thick flange between the intake runners on the Corolla manifold and the intake ports of the Yaris head. :thumbsup:

The Danger of Power Pulleys &
Understanding the Harmonic Damper
BY STEVE DINAN OF DINAN BMW

I have been threatening for a long time to write a series of technical articles to educate consumers and to dispel misconceptions that exist about automotive after-market technology. Motivated by problems with customer's cars resulting from the installation of power pulleys, I wish to explain the potential dangers of these products and address the damage they cause to engines.

The theory behind the power pulley is that a reduction in the speed of the accessory drive will minimize the parasitic losses that rob power from the engine. Parasitic power losses are a result of the energy that the engine uses to turn accessory components such as the alternator and water pump, instead of producing power for acceleration. In an attempt to minimize this energy loss, many companies claim to produce additional power by removing the harmonic damper and replacing it with a lightweight assembly. While a small power gain can be realized, there are a significant number of potential problems associated with this modification, some that are small and one which is particularly large and damaging!

The popular method for making power pulleys on E36 engines is by removing the harmonic damper and replacing it with a lightweight alloy assembly. This is a very dangerous product because this damper is essential to the longevity of an engine. The substitution of this part often results in severe engine damage.

It is also important to understand that while the engine in a BMW is designed by a team of qualified engineers, these power pulleys are created and installed by people who do not understand some very important principles of physics. I would first like to give a brief explanation of these principles which are critical to the proper operation of an engine.

1) Elastic Deformation
Though it is common belief that large steel parts such as crankshafts are rigid and inflexible, this is not true. When a force acts on a crank it bends, flexes and twists just as a rubber band would. While this movement is often very small, it can have a significant impact on how an engine functions.

2) Natural Frequency
All objects have a natural frequency that they resonate (vibrate) at when struck with a hammer. An everyday example of this is a tuning fork. The sound that a particular fork makes is directly related to the frequency that it is vibrating at. This is its "natural frequency," that is dictated by the size, shape and material of the instrument. Just like a tuning fork, a crankshaft has a natural frequency that it vibrates at when struck. An important aspect of this principle is that when an object is exposed to a heavily amplified order of its own natural frequency, it will begin to resonate with increasing vigor until it vibrates itself to pieces (fatigue failure).

3) Fatigue Failure
Fatigue failure is when a material, metal in this case, breaks from repeated twisting or bending. A paper clip makes a great example. Take a paper clip and flex it back and forth 90° or so. After about 10 oscillations the paper clip will break of fatigue failure.

The explanation of the destructive nature of power pulleys begins with the two basic balance and vibration modes in an internal combustion engine. It is of great importance that these modes are understood as being separate and distinct.

1) The vibration of the engine and its rigid components caused by the imbalance of the rotating and reciprocating parts. This is why we have counterweights on the crankshaft to offset the mass of the piston and rod as well as the reason for balancing the components in the engine.

2) The vibration of the engine components due to their individual elastic deformations. These deformations are a result of the periodic combustion impulses that create torsional forces on the crankshaft and camshaft. These torques excite the shafts into sequential orders of vibration, and lateral oscillation. Engine vibration of this sort is counteracted by the harmonic damper and is the primary subject of this paper.

Torsional Vibration (Natural Frequency)

Every time a cylinder fires, the force twists the crankshaft. When the cylinder stops firing the force ceases to act and the crankshaft starts to return to the untwisted position. However, the crankshaft will overshoot and begin to twist in the opposite direction, and then back again. Though this back-and-forth twisting motion decays over a number of repetitions due to internal friction, the frequency of vibration remains unique to the particular crankshaft.

This motion is complicated in the case of a crankshaft because the amplitude of the vibration varies along the shaft. The crankshaft will experience torsional vibrations of the greatest amplitude at the point furthest from the flywheel or load.

http://www.atiracing.com/products/dampers/dinan/image2.jpg

Harmonic (sine wave) Torque Curves
Each time a cylinder fires, force is translated through the piston and the connecting rod to the crankshaft pin. This force is then applied tangentially to, and causes the rotation of the crankshaft.

The sequence of forces that the crankshaft is subjected to is commonly organized into variable tangential torque curves that in turn can be resolved into either a constant mean torque curve or an infinite number of sine wave torque curves. These curves, known as harmonics, follow orders that depend on the number of complete vibrations (cylinder pulses) per revolution. Accordingly, the tangential crankshaft torque is comprised of many harmonics of varying amplitudes and frequencies. This is where the name "harmonic damper" originates.

http://www.atiracing.com/products/dampers/dinan/image3.jpg

Critical RPM's
When the crankshaft is revolving at an RPM such that the torque frequency, or one of the harmonic sine wave frequencies coincides with the natural frequency of the shaft, resonance occurs. Thus, the crankshaft RPM at which this resonance occurs is known a critical speed. A modern automobile engine will commonly pass through multiple critical speeds over the range of its possible RPM's. These speeds are categorized into either major or minor critical RPM's.

Major and Minor Critical RPM’s
Major and minor critical RPM's are different due to the fact that some harmonics assist one another in producing large vibrations, whereas other harmonics cancel each other out. Hence, the important critical RPM’s have harmonics that build on one another to amplify the torsional motion of the crankshaft. These critical RPM’s are know as the "major criticals". Conversely, the "minor criticals" exist at RPM's that tend to cancel and damp the oscillations of the crankshaft.

If the RPM remains at or near one of the major criticals for any length of time, fatigue failure of the crankshaft is probable. Major critical RPM’s are dangerous, and either must be avoided or properly damped. Additionally, smaller but still serious problems can result from an undamped crankshaft. The oscillation of the crankshaft at a major critical speed will commonly sheer the front crank pulley and the flywheel from the crankshaft. I have witnessed front pulley hub keys being sheered, flywheels coming loose, and clutch covers coming apart. These failures have often required crankshaft and/or gearbox replacement.

Harmonic Dampers
Crankshaft failure can be prevented by mounting some form of vibration damper at the front end of the crankshaft that is capable of absorbing and dissipating the majority of the vibratory energy. Once absorbed by the damper the energy is released in the form of heat, making adequate cooling a necessity. This heat dissipation was visibly essential in Tom Milner's PTG racing M3 which channeled air from the brake ducts to the harmonic damper, in order to keep the damper at optimal operating temperatures. While there are various types of torsional vibration dampers, BMW engines are primarily designed with "tuned rubber" dampers.

http://www.atiracing.com/products/dampers/dinan/pully_wp.jpg

It is also important to note that while the large springs of a dual mass flywheel absorb some of the torsional impulses conveyed to the crankshaft, they are not harmonic dampers, and are only responsible for a small reduction in vibration.

In addition to the crankshaft issue, other problems can result from slowing down the accessories below their designed speeds, particularly at idle. Slowing the alternator down can result in reduced charging of the battery, dimming of the lights, and computer malfunctions. Slowing of the water pump and fan can result in warm running, while slowing of the power steering can cause stiff steering at idle and groaning noises. It is possible to implement design corrections and avoid these scenarios, but this would require additional components and/or software.
Our motto at Dinan is "Performance without sacrifice" We feel our customers expect ultra high performance along with the legendary comfort and reliability of a standard BMW.

While it is common that a Dinan BMW is the fastest BMW you can buy, performance is not our only goal. Dinan isn't just trying to make the fastest car. Instead a host of considerations go into the development of our products. Dinan puts much more effort into these other areas than does our competition.
These considerations are Performance, Reliability (Warranty), Driveability, Emissions, Value, Fit and Finish. We feel that the power pulley is a bad way to get extra power from and engine and the potential for serious engine damage is too great.

This is a simplified explanation meant to be comprehensible by those who are not automotive engineers. In trying to simplify an extremely complex topic some precision was sacrificed although we believe this explanation to be as accurate as possible. We encourage our customers to educate themselves and understand the automotive after-market because we believe that our products are the best researched, engineered, and fabricated products available.

I No that i post it and i am Experience with it, the rubber you are making fun of it will balance the engine due from unwanted vibration, ask your self this why the hell most of drag race Engines have ATI Damper,
Here is a simple answer that is to balance it also it can save The trans as well and To rive more RPM's and not to be afraid about it.

[eTiMaGo]

from what I understand, V engines are more prone to harmonic imbalance, for which a rubber damper is a good idea. But for a modern, "weak" I4, it would not make a difference...

As a kid in auto shop I was taught that harmonic balancers served a useful purpose... but that was when dinosaurs roamed the earth! :laugh: The long crankshafts of inline "straight six" cylinder engines (used to be as common as 4 cyl engines are now) especially benefitted from having a damper. Maybe with improved metallurgy, more precise balancing, and smaller shorter engines today it's not as important as it used to be.

Ok so just out of curiosity stock MTX yaris's will get between 90-100whp, I/H/E = 95-105whp, I/H/E + 1ZZTB&IM = 105-112whp, I/H/E/TB/IM/ + pnp head & prius pistons = ~129whp. what about valve jobs and cams could you in theory squeeze out another 10whp out of this engine. Even if we could hit 140whp looking at these numbers really makes me want to do some research the 2ZR-FE I4 swap and hope for ~135whp before having to crack open the engine.

Your best bet is to start a new thread and also do some more searching on the forum as it has been discussed several times. This thread is really for Dyno work as the subject states. Not trying to be a douche outright. Just want to keep it on topic.

The quick and dirty though:

Cams: regrinds are around $760 for the cams and that includes only the grind work. A pair of JUN cams direct from them as of 3 years ago was around $1000-1100 for the set.

Pistons, gaskets, head studs, etc: $800+ ?

IHE: I would think that unless you do all of the work yourself to include the exhaust work you are easily looking at $1200-1500.

Then you need engine management. PnP harness and Camcon and FIC other the likes from Greddy and you are looking at another $1000 in parts.

Then there is any associated labor involved that you would not be completing yourself plus the additional basic tuning along with continued tuning every so often.

Just in parts you are looking at easily 4k for decent quality parts. Then labor, tuning, upkeep.

I would think that the 2zr swap would be a much more feasible and reliable route unless you are a person that really enjoys the whole performance modded lifestyle.

Dyno'd tonight to baseline on the dyno the car will be tuned on once Im done the turbo fabrication. Was told this dyno tends to read low. Well I have higher numbers then what I had 2 years ago on a different dyno (both dynojet).

I think the ECU has worked around the Tooter and given me some good numbers compared to when I first installed it and dyno'd it right away. Previous was 104/103 and prior to the Tooter was 107/104, both on the other dyno.

Note that internals are still stock. Intake manifold is still the stock yaris 1nzfe. This is all the external mods that has been done. Just want to know if this gains is somewhat okay with the mods I have put in. I am just curious and wondering how some can manage to do a 120hp and 150 or 152nm. I am not trying to get very high numbers just wondering if it also depend on the tuner on how they feel comfortable at tuning it. Thanks!
