E36 325 Engine Turbo'd With 8 PSI... Fast Or Not? - Page 4

_DIESEL_ · 05-01-2006, 10:44 AM

I tottaly agree with you my turbo is farly small it's a t3/t4 that's why i barly have any lag but the dyno graph is made of what turbo size that's why i said proper size turbo. Usually people put big turbos because they think bigger is better not always. With n/a car you don't have that much to play with s/c you limiter to some psi 15 or 18 max untill it can't flow any more CFM , turbo just trow out the old one and slap on little bigger if you need more boost right turbo these days are cheap this way he'll have more room to play with and this way it can make the most power.

Listen my car is a 325 with 10psi i made 460 to the crank. If that helps in any way. just bc its a 325 or 328 dosent mean u cant make big hp u just have to rum more boost. NO big deal

To be honest, I'm having hared time believing this.
What kind of engine work you've done?

AA kitted stage II M3 does 460hp at the crank, and thats on 14psi.

i thought he was running a GT35r.. it will create some big numbers.

aa kits are junk. outdated and over priced. gt35r 328's make around 450whp on 12-14 psi.

What difference does it make? Why one turbo will give you more HP than another with the same PSIs?
Not doubting you, I'm just clueless.

Here is a list of GT35T turboed cars

After seeing 2 cardcounter's results I decided to see how much his car would have at 10psi.
Here are cardcounter's results (328)

21psi - 543whp/512tq
25psi -635whp/574tq

thats 92rwhp from 4psi, or 23rwhp for each psi.
so if he would run 10psi, he would have 313rwhp

What do you think?

paul · 05-02-2006, 08:52 AM

well how much is drive train loss add up 2?????? bc i ran 360 to the rearwheels at 10psi, so i added 25% to that to get my crank hp numbers, if that 25% is to high then sorry but i still ran 360 to the rear wheels, have it on tape if u would like to c it, plus u cant compare setups each car is different, also i am runnig higher comp then cardcounter, so 10psi at 9.5 comp is goign to make more then 10psi at 8.5, sp b4 u start calling b.s ask to find out what ppl r running thanx

paul · 05-02-2006, 09:01 AM

Do u know why cardcounter makes so much Hp? Do you know why he dosent blow headgaskets? Do u Know why he runs such high boost to make hp numbers that an m3 would make at half the boost level? To be honest i have spoken to him and the guys at ics a number of times. You can not base all ur ideas or views on one setup, Until u strap ur car to the dyno and try things u have no idea, I dont mean to flame, just i am sick of ppl saying i heard or i read.

Drivetrain loss is 20%. Considering average M3 dynos at about 200rwhp.

Anyway, I really wasn't calling you claims BS, just seems 360rwhp out of 325 on just 10psi is kinda high.
Still what kind of engine work you got?

He is on race gas, Im sure he makes much less HP on pump gas. There was a thread on bf.c, another 328 dynoed on race and pump gas. I tried to find it, but couldn't.

I doubt M3 would make 630+rwhp at 12.5psi.

I'm not basing my ideas on his setup. In fact I think his setup is one of the craziest out there. I mean I dont know anyone making 20+rwhp out of 1psi.
That's the most extreme, so regular car would make much less.

But to be honest, I aslo think ICS numbers are not exactly true

Vlad, a more efficient and modern turbocharger can flow more CFM's at the same PSI as an older, outdated turbo. That's were the power difference comes. Also, the new Garret's (with ball bearings) can spool up much faster, and with a proper compressor/turbine ratio you can almost elimitate turbo lag.

i never said an m3 could make that hp on 12 psi. but i do know of a m3 making 700 to the crank on 17psi

What do you think?

do a search. i am pretty sure there is a vid of him dynoing 440whp on 91.
