2000 Trans Am Dyno
the main reason i said to watch the fuel pressure was back when JPR and I put my car together we had no issues with fuel. My fuel pressure from the stock intake pump and the trex seemed to be enough until we hit the track and blew the motor. I tried to fix the problem by replacing the fuel pumps etc... but the fuel pressure still dropped even at an idle. After replacing the entire fuel system with aftermarket rails, lines tank and pump. the problem went away and i am still using my 38lb injectors and pulled well over 500 rwhp unlocked with a vig 4000 stall. good luck that car is going to make great power.

I'm awaiting the results too as this is what this thread was made to show. I didn't realize you were asking for our advice on how to tune the car for more power hence I didn't feel it was a "tech" inquiring post. That's why I posted no "tech" advice. I was just asking for no "CAPS LOCK" in the interim.
When I read it I get the impression of the highschool bully yelling at everyone trying to get attention. Your results of the power so far are great and would still be well received without the CAPS LOCK. I know you're excited, as are we, so all I ask is a cutback of the CAPS LOCK. Your results speak for themselves and don't really need an entire post of CAPS LOCK.

Verdad Gallardo Those #'s are still awesome JD. As of now I cant remember if anyone has dyno'd that much with a H/C SC'd car with no headers and ls1 intake. I am sure some of the FI guys will chime in and give their opinion. Once again Congrats!

Wow! This is the second great result this week I have seen from a centrifugal stock internal LSx with manifolds. A guy posted over on Z06vette that he made 550 RWHP through manifolds and cats (stock heads and cam) @ 7PSI from a procharger, with the same 38# injectors ('03 Z06). Extremely impressive.
Guys- I do not visit the FI section very often, have these cars become more reliable with FI setups? I used to remember reading about heads lifting, blown headgaskets, and busted pistons back in the day....Maybe all of the good LS1edit tuning has made blowers more safe in LSx applications?

Vince, I wasn't there today when the dyno tunning session took place, but it looks/seems fine to me besides needing a bit more injector, the one FI 8psi car I did went 537 unlocked and 550 locked so I believe this car is right in line with those old numbers with basically the same exact heads..

, LS6 intake, 9 to 11lbs of boost, and more tuning. You guys might want to try alchy and try a different pulley and go for 15lbs of boost.

I saw that car on the dyno, and those numbers are pretty damn impressive, especially how flat that torque curve is. But, its probably a good thing that he expects the car to blow up because I cant see 8psi lasting long on ~11.0 CR heads on a stock bottom end...

I believe that was me that said you need headers, exhaust and intake to be near 550rwhp. Thanks for posting your corrected #s that helps , good power , nice curve. Have you ever take it to the track, what Times you got and mph, Dyno is a dyno doesnt impress me much, but either way still some GOOD NUMBERS. congrats

it just got off the dyno,waiting for correct size injectors and will redyno.the customer will take it to the track and keep us posted.
compression is stock--not 11 to 1.
the heads on it are 98 ls1 heads ported--this is what the customer wanted and supplied.
thanks
