dyno

[bibi6979]

i had the car dynoed this past week. It was really bad, i think that the Nitrous did not hit as good because the bottle was cold. And how the hell can i only get 130 WHP(no NO2) with a injen cold air, aem pulley, fidanza flywheel, tanabe racing medallion, S-afc, custom pipe with no cat.All of that for like 10 WHP. I aslo got a sorry 163WHP with NO2........................ Bulllshiiiit.
And how the hell woul'd a 75 shot of NO2 would only give me 30 WHP.It's a piece of ****, i'm saving up to get my 2004 WRX STI, coming out summer 2003. Now, that's a real car!
I got a pic of the dyno sheet, maybe someone can explain how i got more torque than horsepower.

Relax. That's actually not to far off where you should be. I think you may be 5whp off w/o the bottle. About 10-15whp off on the N2o. Was it SAE corrected? What was the pressure of the bottle?

[bibi6979]

i don't know what SAE corrected is and i don't have a prssure gauge on the bottle. I didn't take the car to the dyno myself, i took it to titan on thursday night and they i went to pick it back up on friday night. I think they fuuuking tried me or something, i think they could have did more run or something, would heavy rims have anything to do with the low WHP?

Not heavy, but what size? If it's larger than stock then you just found your problem.

[BoyRacer]

well you have a GT right. thats about normal for a GT with those mods....get a header. and either you have some big ass wheels, or you the bottle pressure was low. and what kinda N20 system in it? NX is measured to the wheels. and last but not least, does bottle even have a dyno yet? i didnt think he got it yet, was this a butt dyno, or was this on a dynojet?

[bibi6979]

i have 17" wheels, AEM big brake kit in the front, but last time i took my wheels of and compared the weight to the stock one, they felt a lot heavier. They did not dyno it a titan, if you look at the picture i put up, they did it at Norris motorsport(dynojet) 407-656-2600.

Weight doens't matter on a dyno so much as the tire being a full inch or 2 inches in the gt's case. It's that much more that it has to spin before a complete revolution. Considering you have 17"s on a GT with those mods, you have very respectful numbers.

[bibi6979]

i still don't like it all all, what the hell is 130 WHP, nothing! I can't wait for my STi! :)

[EzRidA]

130whp in something that weighs 2250lbs is actually decent. It's all in the driver.

Bibi, how much did you end up paying for the dyno itself? Did they tune the S-AFC and were the hp numbers different when they used the tuned S-AFC??

[bibi6979]

i end up paying $500 for them to do the custom pipe and to dyno-tune the s-afc, sounds like i got ripped off, $350 for the dyno session, and YES the 130.4WHP was with the S-AFC tuned, shiittyy!!!!!!

[Acilec]

Don't forget that you're talking about horsepower to the wheels. 130 with your mods is ok. You probably have around 165 brake horsepower now.
