wt is the most boost a stock motor can take b4 it detanates ???

 

If you're talking about detonation as in knock, then it does that stock with the stock tune and stock boost level.

If you're talking about amount of boost pressure before something hardware-wise is guaranteed to give out... well... we haven't found out yet... somewhere above 30psi as people are already running that much without issue.

 

You should find out and let us know!

 

wt a buddy let some one else pop a moter lol not me i have a
v8 ls1 and a v8 gt the ls1 is turbo and it makes about 10 PSI

detonation is not good thats when pistons get holes in them or main caps fail !!!!

 

There comes a point when more boost pressure alone isn't better. After all, manifold pressure is air that isn't getting through, and you're wanting more flow in the end. Bigger turbo, ported intake manifold, and forged pistons to support the extra flow would be wonderful. You wouldn't see as much boost pressure, but that's because it'd be flowing the air more efficiently.

 

very true i have never messed with any small turbo cars sorry u all but i do have a turbo ls1

 

Well, just get yourself a downpipe and a tune and this thing will wake up in a big way. That small turbo car would take your LS1 with nothing done but a tune if your LS1 wasn't boosted. They're very impressive. I think you'll be pleasantly surprised, as it's a whole new car when tuned.

 

Hp turners is wt i have but i dont have a cobalt yet ??? just trying to learn about them some more

 

Oh you already have a boosted car so you know boost is not directly proportional to power.

 

If you're comfortable with HPTuners, then you're in luck, as that is one of the main software suites that people use to tune our cars. There are many knowledgeable tuners on here that can help you if you would like somebody to help you tune. There are a lot of small things about this engine that makes it much different than most to tune. I'd highly recommend reading up on them before trying to tune it. Things such as direct injection drastically change the tuning approach.

I'd also check the HPTuners forum for tips on tuning this engine if you try doing it yourself.

 

hey thanks i will do man !!! i asked about the motor compartment on the other page and there is just a bunch of smart asses on there lol!!!! i know more then they think !!!!

 

27-28 PSI before bad things will happen.
