30th t/a

Im new to the procharger world and i know 7-8 is about the max "safe" limit for a stock LS1 but I see people blowing up their stock LS1 on 7 & 8 psi...so I was curious to find out what is the lowest PSI that someone blew thier stock LS1 up on?

I just bought a 01 WS6 with a P1 on it making 4psi and Im planning on installing a Alkycontrol Meth setup & a dynotune and possibly upping the boost but at this point, keeping the motor alive is more important than making big power. Basically Id rather have 425rwhp and no worries vs 480rwhp with a chance of blowing it up.

That is a very loaded question, and completely relative.

People blow their motors in N/A configurations.

Depends on power adder, timing, IAT's, fuel system, mileage, and many many other variables.

Not trying to be a smartass, just saying...

With meth I would not be scared of 8-9 psi on a stock ls1. Just take it to a GOOD tuner that knows what they are doing.

i got a customers 2002 camaro up to 9psi. then backed it to 8psi and he ran that for about two years.

i hope to push a stock 89K mile ta to around 10-12 with the help of e85. but time will tell.

The enemy is more RPM than PSI related assuming everything else is correct.

I personally think the quality of build (plus tune) and how the person treats the car has a lot to do with reliability. I also think that RPM is a greater risk then PSI.

+1..that and detonation, i ran mine on 14 psi for a while with me tuning (and im no tuner for sure) i sold it and last i heard its still running strong. I kept it under 5800 rpm, kept the afrs about 11/10.7:1, and used a lot of meth. the car had 70k when i got it

it is def. in the tune, detantion is what kills engines keep IAT down and plenty of fuel 10-12 psi all day long, my factory ls2 is at 13psi right now so far so good
