lets see if this thread gets any replys, lol. im curious as to what people are putting down on the rollers / what the track times are around the 9-10 PSI level. my car will be tuned to 10 pounds this weekend and i cant really find anything in that ball park that is consistant. through a tight stalled 60e and a stock engine i'm looking for 475-500 RWHP and traps in the mid 120's.

A little more detail on your car may help?

go run it and find out, just because another car goes a certain time doesnt mean yours will, might go faster or slower.

well since its a 60e hopefully your trans survives.

The Trans is good its got about 3000 in parts and was properly built..i'm aware all cars differ but I probably won't track the car until the end of summer because its too far and expensive. Posted from LS1Tech.com App for Android

10lbs isn't 10lbs on two different turbos. I would hope my gt91 would make a little more power and go a littler faster on 10lbs than a t76 or similar, lol. You can't just use boost pressure. 500whp will probably run in the mid 11's maybe a touch quicker, also depends if the car has a good suspension under it and on what tire.

360cfm ported LS3 heads are going to work magic vs. 260cfm stock heads.

10psi means nothing without any more info on what you are running. Every turbo is rated at a specific lbs/min volume of flow.

My buddy made 950rwhp on 14psi with a forged LS3/ported LS3 heads/intake and single T4 turbo. On 10psi it probably made 850rwhp. It was a GTS76 with custom wheels on both sides.

I understand guys but I already said the setup a few times...stock motor and compression, 70mm .96 ar, 2.5" inlet and 3"outlet. Simple.

That sounds about right 475-500 . My 98 with a stock engine with ls6 intake made about 500 @ 10 psi with a d1 procharger through cats.

Thats what i figured. My last ride @ full weight unlocked stall 410 RWHP trapped about 118 100 pounds heavier then this car so another 70-90 RWHP unlocked should get me in the 120's maybe even higher who knows my tuner is pretty confident in LS bottom ends lol.

My SS with 10psi and a few preturbo exhaust leaks made 528whp. It has an STS 67mm setup. With the leaks done I couldn't say. I also have 243s and a midsize cam.

nice results

Cool, thanks. Using the 1 bar = double the power equation with 300 whp as a baseline it still comes out right around 500. Ill let you guys know how i make out.

Idk yet but ill find out tomorrow what I run but im running 13psi on a t76 rearmount,problem is I may start to play with boost and the tune while at the track

stumprrp

iTrader: (2)

Im going to tell the tuner give it as much boost as he feels comfortable and keep it lean with low timing. Then again he probably knows that lol.
