10psi on stock lt1?? my buddy just got a sts kit with a t67 with injectors and pump and everything else. he wants to run 10psi on the stock motor. to me that seems pretty high. i dont think he would listen to anything i say but i just wanted to see what you guys think. it is non intercooled and no alky injection. thanks

6-7 PSI on a stock bottem end is Risky. I would have it detuned ( if possible ) to around 5 PSI.
Forged Rods and Pistons are required along with several other things if you want a reliable S/C LT1

I've been running 7 psi with my sts for a few months now with no problems, but with a Speed Inc. tune. Motor is completely stock. I don't have an intercooler or meth injection either. Of course I might blow up next week. That'll be my opportunity to go all out with a new motor.

It probably wouldn't break right away, but I don't think it would last a long time like that.

I would do it nonintercooled if it was my setup, but thats just my .02
TwoFast4Lv- What kind of setup? No boost controller? I'm not sure what accessories they sell with that STS kit.

I ran 10psi INTERCOOLED for a long time on a stock LT1. Using a D1-sc with the twin intercoolers.
The motor had a powerdyne on it for about 20K miles before that. The powerdyne kit made 6psi non-intercooled.
It would detonate if I got bad gas, or if it was really hot outside. Other than that it ran OK.
IMHO, 6psi isnt worth the cost of the kit. 10psi was def worth the cost though.
