Holy hell is this car slow. :laugh: I got the dyno for a Honda Fit Sport too. Here it is in comparison to my Yaris.

thanks for the specs m8..

[5spBlazer]

Very nice!

[tekmoe]

very surprised regarding the low numbers for the Fit. doesn't seem right...

[Black Yaris]

Yeah Honda sux!

[Blenjar]

i knew it, u cant go over 100...
THX!

[JosephDoc]

Nice! I see some hope now.
I wonder how many pony-power more if without your header... since a header swap is not as common as exhaust+intake only?

[Black Yaris]

what exhaust do you have? I know you can push over 100whp with intake, exhaust, header.... with the right setup...

[Black Yaris]

how about I learned to read.... I bet if you would have went with a lil better exaust like a true cat back you would have pushed 100whp, your exhaust is still choked down after the resinator to the muffler, restricting the flow.

[Sabretooth]

Get Crank Pully ASAP!...we need Dyno!

Rinse and Repeat in July when NST gets the WP and Alternator pullies done.

What did you expect? The engine is only rated for 106 HP at the crank stock, then you have to account for the loss through the drivetrain. 97 is actually pretty darn good.

[grampi]

Typical Honda, all HP and no torque.

[ChinoCharles]

Ran, was this with or without the R-FIT?

[dngz]

so would my wr short ram intake, megan racing header, and custom 2" catback exhaust, nst crank pulley, and fidanza flywheel be pushing 100-105whp u think??

[Pars]

wow, the rpm on the dyno starts off when the rest of us mundane drivers are upshifting. I bet my stock liftback can blow the doors off your souped up Yaris from 0-3000rpm :biggrin:

[grampi]

Pars, I'm sure it could. Usually the first thing that disappears when they start souping up these little belnder motors is the bottom end torque. Peak HP will increase, but at the cost of power in the lower RPM range. That's why I wouldn't even consider any engine mods unless they increase power across the entire RPM range.

[falkor_99]

good to know

[ChinoCharles]

How many of you guys talking like you know something have ever been in the same room as a dyno? 2000 RPM is a perfectly acceptable engine speed to start a dyno run at. The fuel economy thread is there for anyone that wants to hop on a soap box about granny driving.

I've seen plenty of dyno runs and it's been my experience when peak HP is gained, power is lost on the bottom end.

[Pars]

Starting off at 2000rpm is all well and good on the dyno. But on the streets, if I was always starting off at 2000rpm, I'd be on my third set of tires (instead of my second set).

If the mods were able to increase initial torque without taking away from the higher rpms, then I'd be truly impressed and quickly drop my hard earned money for the add-ons. That kind of upgrade would not only make the car faster, but actually improve fuel consumption. It might not make you kind of the racetrack, but it would make you king on the streets.

i would think so. certainly 100whp. i don't think thats bad considering the factory rating. actually pretty decent for the amount of work... needs some tuning, little more airflow and exhaust.

Sadly I gotta agree here. I want to go from 0-60km/h faster in the yaris. Not from 60-100km/h faster... you know what I mean?

Not knocking those of you after gains up top... just not what I want... and I bet the majority of people would probably want 0-60km/h acceleration as opposed to 60-100km/h... cuz we're not tracking it, we are driving in traffic...

+1 :thumbsup:

Mods like the NST pulley set should increase power throughout the whole RPM range. I'll be getting that as soon as it becomes available (July apparently).

[churp]

Did I miss something? Seems like people are assuming low rpm power went down.....does anyone have the dyno graph of the stock setup to compare before trashing the modifications (in a lot of peoples minds improved mod's)

[pathetiq]

i dont get it, dont the yaris have 105hp and 106torque by factory default and with mod youre under 100?

[lostmind]

pathetiq, it's 105/106 at the flywheel? and then you have the losses getting that power to the ground. The dyno shows HP/TQ actually put out at the wheels...

A stock yaris dyno's around 90hp? I think I read that on this site somewhere.

Hey churp,
It's not that I think low end was lost, it's that the gains are mostly in the higher rpm's. To me, that's a part of the power band I won't be driving in the majority of the time...

Although I do think it'd be killer to see someone take a yaris and lighten the crap outta it, toss in a turbo or just spend $5-10k and go NA and beat the snot out of it at the track :)

[lostmind]

And to the OP I just want to say thanks for investing your time and money into your car and then sharing with the community. Without people like you, the rest of us wouldn't be able to make informed decisions on upgrades...

I understand what you're saying....just want to make sure everyone understands that power on the low end isn't necessarily lost. Cubic inches and turbo or super will give more torque at the cost of gas.

BTW I'd rather see a T-Rex in my garage than a souped up Yaris....it may get better milage! :biggrin:

http://yarisworld.com/forums/showthread.php?t=2639&highlight=weapon-r+dyno

Weapon-r dyno says stock 76 tq and 77 hp at the wheels.

So 100whp is not too shabby!

edit: okay, i just saw the other recent dyno chart. 90whp?! wtf, now im so confused...

[lostmind]

Different brand of dyno maybe? I am no expert on this though...

[Ran Kizama]

Get Crank Pully ASAP!...we need Dyno!

Rinse and Repeat in July when NST gets the WP and Alternator pullies done.That's the plan. I'm going to get all three pulleys at once then hit the dyno again. :wink:

Ran, was this with or without the R-FIT?This was without the R-FIT. I'm actually selling the R-FIT now. If you or anybody else is interested in it, PM me. It's still in the box. :thumbsup:

And to the OP I just want to say thanks for investing your time and money into your car and then sharing with the community. Without people like you, the rest of us wouldn't be able to make informed decisions on upgrades...My pleasure. Glad to be of service. :smile:

[mojoyaris]

Nobody talks about the big throttle body kit and the Blitz RVit that can adjust the fuel and air mixtures. I'm curious how much extra hp this would bring on top of the intake, exhaust, header setups.

[nsmitchell]

The ZPI Turbo kit said it actually increased MPG by 2-3MPG, but you must use high octane fuel, so it all evens out. Now if you go stompin' the gas everywhere you will probably get no better than 30MPG... probably a lot less.

[largeorangefont]

WTF are you guys talking about lack of low end power?

First, there is no stock chart to compare these numbers to so it shouldnt even be discussed.

Second, The dyno chart shows the car has 90% or more of its peak torque from 2000 to 5000 RPM. What more do you want??? That is a pretty broad powerband for a little motor.


Look and the numbers compared to the Fit. The Yaris hits peak torque at about 4000 RPM, the Fit 5000. The Fit started out at a higher RPM and still looks like it had NOTHING on the bottom end. It is just starting to wake up at 3000.

[dngz]

can anybody explain why 1 dyno had 77ish whp and 1 dyno had 90?? and what are the real numbers at the wheels on a stock yaris?

[Pavel Olavich]

It seems that most of those mods for the Yaris are a super big waste of $$...doesn't anyone find out first, if a mod is going to increase performance, or does one just like the braggin rights of having a CAI, or mod exhaust? :iono: :iono: :iono: :iono:

Dyno numbers are not comparable between dynos.

[Vanderkitten]

so would my wr short ram intake, megan racing header, and custom 2" catback exhaust, nst crank pulley, and fidanza flywheel be pushing 100-105whp u think??

Dude, if your pulley is not undersized, your flywheel and your pulley don't make any HP difference. IT will rev faster, but they dyno run will be done in 3rd grear where you will have lost the effect of a lighter flywheel. Its resisting the wheels, so it can measure the output.

Don't get me wrong, if 2 engines are putting out 100HP to the wheels, the one with the lighter pulleys and flywheel will be slightly quicker, and on a track, where you are coming out of 10-15 corners, it makes and even better difference! =)

FLAMERS: Correct me if I'm wrong... I've got thick skin... and back it up with dyno charts.

[Vanderkitten]

Nobody talks about the big throttle body kit and the Blitz RVit that can adjust the fuel and air mixtures. I'm curious how much extra hp this would bring on top of the intake, exhaust, header setups.

Adjustable fuel mapping would probably give 2-3 HP peak over stock ECU and Headers, pipes, intake.

The best thing it could do is turn that Mountain Range of a dyno chart into something resembling a proper power curve. I think this is a HUGE thing that is overlooked on this forum: POWER CURVE v. PEAK HP. If your curve is sloppy, who cares what a snap-shot of your peak HP is?

Even with a car with a self-adjusting ECU (remember, it operates within a pre-set range based on a model of economy, not all-out performance), the correction cannot be made (in the best way possible) to accomodate a new intake, header and exhaust.

If you look at a motorcycle, say a DUCATI, or even a GIXXER, you cand do a K&N filter for $65, a new carbon or Ti pipe for $500, and gain absolutley nothing but sound. It's not until you throw in the $349 power commander that you see some good gains... and we're talking 5HP.

So, if our car dynos around 80-84 FWHP(like the FIT), and you can spend $189 on headers, $199 on exhaust and $200 on an intake, you are getting 15-18HP at the wheels for $600. In terms of $$/HP, this is CHEAP!! Sign me up!!:thumbup:
