How much HP can a stock ls2 handle? I have an 06 gto with a D1 procharger. Its at 10psi and made 550rwhp through a slipping trans. I just bought a built trans and I'm looking to turn the boost up to about 13-15psi on e85. The bottom end is stock with stock internals. So much question is how much hp can a stock bottom end ls2 handle?
Thanks

I agree. The question is also how long. I am running a stock 5.3 with a 180,000 miles on E85 and just to note on this engine I have the coolant lines to the front and REAR. So far it has lasted about 6 months at 25lbs of boost tuning myself. However, at this boost level it could go anytime. I would think at 15lbs with a good tune on E85 it should last for a long time stock. IMO
I made 963rwhp through a glide with mine. It was all stock other than arp rod bolts. We ended up stretching the rod journals.keep it around 700rwhp and it will live for a long time.

As two people have said before me, the engine can be tuned to handle 800+rwhp. But don't expect that to stay together for more than a handful of pulls...
On 93, a well tuned LS2 can handle some 5-600rwhp reliably. With E85 you can probably go a little higher than that.

Thanks guys and yes I don't except it to last forever making 700+rwhp. The car is a weekend cruiser and track car so it sees make 2-3k miles a year (maybe a little more). But, I would like it to last longer than just the tuning process lol.
I have also been tossing the idea of leaving it on 93 but throwing a meth kit on it instead of e85. I'm still trying to figure out how much of a hassle e85 is going to be to run on the goat. I'm getting mixed reviews on it; some are saying all I need is another fuel pump, bigger injectors, and fuel rails while others have said I need all that plus a return system and bigger fuel lines. Any suggestions?
Who would a tuner like that be? I live in kentucky and we only have 2-3 tuners for ls motors around this area and I have always had the same guy take care of all of my tuning....

Its a hard pretty much impossible question to answer. I agree with Wicked69... its mostly about how long it will last or who can tune it to make it last for a while and to hold impressive amounts of HP. Also depends the parts you use on that block. The engine itself will handle lots of HP but it has to have a great tune also for durability
