my mods are in sig... my current set up was:

pulley: 2.90
tunning: GM S3
cond: temp 43*, sea level (santa barbara) 3rd gear pull
gas: 91 oct
boost: approx 17-18lbs (sorry didnt log)
no meth


scanforce showed 262,268,272,282,272,282,272 it kept dropping cause i was knocking but a/f was 11.8 across the board so i dont think idc was maxxed but prob really close... anyways does that sound right??? seems a tad high to me in my town it shows const 260-265 but thats at 2500alt... when my meth kit comes v-day and i control knock what do you think it will say then??? my hp scaling on the gauge is at stock it hasent been messed with to read higher...

 

people will say no. i say go to a dyno to find out.

 

hey your running a 2.90 pulley or 2.99???

 

I doubt it man, check this link

page 2 post done by me. My buddys car put out 282whp 286ftlbs of trq with a 2.7 with no meth.
but i could be wrong.

 

that cant be right either i know a guy who is running a 2.5 and 60s and dont push that much hp its really close though

 

Sucks for your buddy
No reason to lie about my buddys car. Knowing now that ppl think those numbers are BS, ill keep my own dyno numbers to myself then, lol.

 

Must have been on one of those new BS dynoes i hear they read 5% lower.

 

Well i am sure lsjwannabe will be on here he is a pro tuner so we shall see what he has to say

 

thats wheel im hp not whp

 

 

nates 2.9

 

*shrugs* alrighty

Oh well then ya man, for sure, i dont see any reason why your not at 282 bhp. Im totally a believer.

 

that seems high i mean gm claims stage 3 makes 260hp on 100oct and 250hp on pump gas i was on pump gas...

 

282 to the crank seems resonable.

 

Well those numbers im sure are to the wheel. I know for a fact a gm stage 2 made 244WHP so well say you make 250whp on stage 3. now add about 15% back to those numbers for drivetrain loss. that should give you a decent estimate of your BHP. so 282 may not be all that unbelievable.

 

do you have drivability issues with the 2.6 and 60s like jerky take offs or rough idle... those are some of the reasons im staying away from 60s...

 

For a long time i had bad idle and what not. But i asked for the assistance of Paul (turbocharged cobalt paul) to give me a hand with the tune. Maybe a week or two later he pointed me in the right direction. And gave me an excellent map i can use with methanol. But as of now, the car on my setup runs perfect.

First off lemme apologize to Hungryhip-ccp for temporarily jacking your thread.

to the ppl who dont believe the numbers. heres the dyno video for your viewing pleasure.



and whos this? oh, its just our local supercharger porter Euthanasia, We just happened to tag along as he got his cars dynoed the same day. heres his 589whp run.



If this isnt enough proof.......bite me.

 

i was seeing around 272 hp on my aeroforce scan gauge in october. The numbers seem right, with drivetrain loss and what not it'll be around 240 whp. I have comparable mods, but still stage 2 around 70 degrees outside and 15psi.

 

I see around 272 on my aeroforce with gm stage 2 and gmpp catback only! I have all of my other mods off for the winter, so that sounds about right. I am also getting lots of knock through 3rd gear with the 91 Octane fuel here in Canada.

 

yeah the knock is what ultimatly drove me to get the meth inj

 

oh don't ruin the fun!

maybe in relation the crank hp. dunno.

i wanna stick one of those on my car and see what it does

 

Lol, sorry sir.

 

i have an idea of what your car does.

 

what?

 

the only thing those guages are good for....is measuring the relative change in HP after a mod.

like 350hp is way off right.....but if you add a header, and it goes to 370....well that begins to mean something....


the numbers themselves are pretty well just numbers.
