Stock GM LS Engine - Big Bang Theory
Stock GM LS Engine - Big Bang Theory
Take the Stock GM LS Engine. We are trying to learn everything about it's limits and we will tell you the results.We get an understandable amount of flack from readers about doing so much editorial on the GM LS-series engines, but there's a reason behind our madness: They're the most popular performance engines today and make completely stupid power when you throw boost at them via a supercharger or turbocharger. Internet forums are all atwitter about just how far up the power scale you can go before the LS finally yells ôuncle,ö but we have yet to see any real proof of its limits. So we decided to find out for ourselves. How much boost can we throw at one, and how much power will it make (and for how long?) before it goes pop in one way or another?

So you're saying I'm OK with 8psi then? That's pretty damn impressive.

Getting 1200 HP from 300 cid at 27 psi is just sick. I would think 8 psi is a safe number if your engine is in good shape to start with. So, what is the limit for an LS engine ????

Detonation is what kills engines most of the time.

Boost is alot of fun. The more boost, the more fun. Breakage is the only thing you have to worry about.

Hmm...when I finally go boosted, I guess I'll be keeping the cubes small and putting my 427 into another car.

holy crap, I'd like to see if cubes really do make the difference. Throw that setup on an ls1 and see what happens.
