max boost or rwhp on LS2 block? Im building my twin turbo ls2 right now and i was just curious on how much hp these ls2 blocks can hold in them without grenading. Here is some info on my setup: Scoggin dickey bottom end, calies crank, rods, JE pistons, hell fire rings, cometic .40 gaskets, afr 225's, fast intake, nick williams 90mm, arp studs, and a set of custom turbonetics ball bearing turbos.
Whats the most hp some of you guys are running through the ls1/2 block?...ive never really heard of these block comming apart, but i just wanted to be sure before i get carried away with the boost button

From what ive heard 750 is pushing it with out a girdle on the bottom end. Alot of flex in teh aluminum blocks. Ive heard of them getting so distorted under boost that they seperate from the heals enough to leak while under load. The bottom end girdles seem to make it possible to run alot mroe power in the LS1's and i would imagine the LS2's. GL man

I have one of our girdles on a stock cap that will see some boost before the end of the summer, after dyno we will disassemble and inspect mains.
