I'm sure I'm in for the dyno. I really want to do the PCA event, but I'm gonna wait for the ER event on Sunday. :eyebulge:

[SaerinRhoe]

Ohhhhhhh ... I may have to play rob the bank for this. :)

[frownonfun]

damn you people and your out of town awesomeness!! if i go to this i'm looking at being gone the weekend of the 10th, 17th, and 24th. sigh.

seriously though i can't find anyone around here to do a dyno so i'll probably be there. hook us up with any updates on time and place when you know.

night everyone.

[lilredrocket]

^Haha. Too bad you live so far out.

night everyone.

At least you have a fast car to get you back and forth!
I'll call today and get the times, as well as making sure they reserve some spots for us. Updates to follow.

[ozmdd]

We should be there by 10 am, and we are officially "invited", so its safe to plan the trip. Lets see if we canget our 3 Yarii to combine for a higher HP than my buddy's EVO X!

So far I have the following people listed as "in":
1.OZMDD
2.frownonfun
3.SaerinRhoe

[lilredrocket]

I may show my face but probably won't have the money to dyno my car

[SaerinRhoe]

Yeah, I'm in and I'm positive in the bank so I'll do the dyno.

Is this the address where it's going to be?
10011 Harmon Rd. Suite #135
Fort Worth, Tx 76177

I got that from a link to a link to a link from Oz's first post.

S.R.

[SaerinRhoe]

I'm officially sick. I was home today with a low grade fever most of the afternoon and I'm generally feeling lousy. Consider this to be my withdrawal from the dyno day unless you all want me to come out there and cough on everyone.

S.R.

[frownonfun]

that's too bad. hope you get to feeling better soon. unfortunately for oz and i, it doesn't look like we'll be beating that EVO's hp afterall.

[ozmdd]

ha! Get to feeling better SR. Well do what we can.

[SaerinRhoe]

Well, it's Monday and I carried my sneezing and wheezing self into work. How did you all do at teh dyno day?

S.R.

[lilredrocket]

ozmdd-----> 106

frownonfun-----> 145ish

[ozmdd]

Actually, LRR, my printout says 107, and Frown's says 137. If we're going to do the math, lets do it equally or not at all. :wink:

[thebarber]

moar dyno sheets.....preferably where we can see #'s

[lilredrocket]

My bad didn't mean to fugde the numbers

[thebarber]

not fudged, just want to see dyno sheets w/ clear #'s on the x and y axis....and the stuff down below...

[frownonfun]

actually my sheet says 127... i got 132 on the last pull but i don't have that sheet.

still would like to get a "second opinion" personally but i figure it's truly somewhere between 135-140whp.

i'll post the dyno i have later on this evening barber.

i dont know, you had another yaris there dyno about what yaris's w/ n/a mods dyno

why do you think its more?

[SaerinRhoe]

And why is Frown's putting out moar?

S.R.

[thebarber]

And why is Frown's putting out moar?

S.R.

power enterprise supercharger

[lilredrocket]

The guy running the dyno said their was about 10% lower than what the sheet said.

[ozmdd]

Try this again...

[frownonfun]

i dont know, you had another yaris there dyno about what yaris's w/ n/a mods dyno

The guy running the dyno said their was about 10% lower than what the sheet said.

right... so according to him, even though my last pull was 132, i'm actually around 145whp. that just doesn't sound right to me. imo there's no way i'm breaking 140 at the wheels. PE never claimed it made that much with the pre-programmed amount of PSI so why would they undersell there product? doesn't seem like something they would do knowing them. with an intercooler yeah but without no.

and barber you say there was another yaris there running about what a N/A with mods is running but you aren't considering that the guy doing the dyno says we have to adjust for the 10% decrease in the dyno numbers.

now i'm not knocking you or your car ozmdd, i very much hope you know that, but, if that guy's dyno was measuring at 10% lower then your numbers would be somewhere closer to 116-117hp at the wheels for a N/A yaris. does that sound right?

i'm just saying i think it may have been measuring the hp lower than it should have but not 10%. 5% lower at most.

just my opinion.

[ozmdd]

Yeah, people claim that the Mustang dyno reads lower than the Dynojet, pretty universally. But there is also debate as to which one is more accurate. Still, there is no consensus on how much, and every A/B comparison I could find on the web involved cars with 3-6 times the HP we put down, so its not really apples-to-apples in simply figuring a %.
I think you can safely assume that you'd run a higher # on a Dynojet, but what that actually means, I couldn't say.
At this point, I'm sticking with the stated #'s. I seriously doubt its off by more than 2-3 HP.

that sounds about right to me. i wasn't aware that it was a universal claim. this whole dyno thing is fairly new to me. shocker right? lol. but i did get the feeling that i was either getting told inacurate info or he was just saying what i wanted to hear when he said i'm probably closer to 145whp.

at the end of the day though i'm happy with the numbers i put up without the adjustment anyway but i just don't want anyone reading these threads and coming away with unrealistic numbers. full disclosure kinda thing.

Its probably closer to 8-10 for yours, give or take.

[thebarber]

sorry, for ozmdd running intake, fart can, and an underdrive pulley 107whp is about right, especially for a dynojet (i ran 98whp w/ similar mods, where a stock yaris did 91whp)

frownonfun, 132whp is pretty decent for a supercharger and whatever kind of custom exhaust you have. im sure w/ whatever safe tune is on the PE piggyback 132 is about right....

[thebarber]

what would make his dyno 8-10whp off and yours not?

[ozmdd]

^He had a run that broke 132 that didn't get printed, so I'm throwing the extra HP on top of my #'s. Edit: By 8-10 more, I mean above the 127 that his chart shows. Compared to a dynojet.

yes and i'm agreeing with that. ozmdd at 107whp and me at 132whp... both reasonable numbers. and good too. 117whp and 145whp, however, not so much.

[PETERPOOP]

People do say the mustang shows lower numbers than a dynojet ( just like the dynapack shows lower numbers than the dynoet ). However, I am not sure by how much. I wish you really wanted to know what your car would show on a dynojet, I know I would. :P

However, throwing out numbers of whp assuming it would be what a dynojet would show (lilredrocket), isn't very accurate......at all. You were making it seem he put down 145whp on the mustang. I mean, chinocharles was claiming for months that the turbo kit he had, put down 180whp before he actually ever dyno'd it; and then it showed 145whp. LMAO.

[thebarber]

my only suggestion is to keep dynoing at the same place as all dyno's vary and the only TRUE point is to measure gains on your car.

though, i always find it best to go w/ a group of the same car so you can measure against known quantities.

a little story: at a local dyno (which im actually going to w/ a group on saturday) i dyno'd 170whp w/ my matrix xrs with intake and cat-back. a bunch of friends from MO were there and we all dyno'd w/i a few hp of each other w/ similar mods.

i later dyno'd at another shop to test my camcon settings for a jdm celica gt-s as well as the 03 vs 04 ecu's (different tq maps and lift engagement).....w/ my OEM ecu and similar mods with or without camcon i was about 183whp....since there were no other matrix's there, the dyno #'s were thrown out by the community as being completely invalid. the only worthwhile item that came of the dyno time was testing the camcon on/off (which, btw seemed to do next to nothing) and testing the 03 vs 04 ecu's, not so much for what i pulled on the dyno, but for what they pulled against each other.

[lilredrocket]

I never said that's what he would make on a dynojet I was only relaying the message that the guy running the dyno said. Which was "Our dyno is about 10% lower than what you are actually putting down" after the math he said "you are actually making about 145 whp"

[ozmdd]

Good info, Barber. I think you're right about it being wise to always dyno at least 2 Yarii at any dyno day. I'm looking to setup a Yaris dyno day on a 2WD Dynojet in the future. We can make sure we get a bone-stock Yaris to set a baseline. Has anyone dyno'd with a throttle controller installed?

[ozmdd]

OK, we get it. LRR and Peterpoop don't agree. Let's move on. :barf: :biggrin:

[SaerinRhoe]

Just to add my half cent, if anyone wants a stock yaris for a dfw dyno run, I'll bring mine out. I wanted to go to this one but I got sick. My yaris is stock engine with a muffler delete. I doubt that would skew the numbers too badly, if at all.

Thanks,

S.R.

[ozmdd]

S.R. - When we do another one, I'll bring my oem muffler so we can get a 100% stock baseline. Thanks!

[jt258]

[jt258]

congrats frownonfun im jealous. like the numbers you pulled. go yarii go!!!
