so how much can a stock ls1 crank handle, i have to get mine checked out to see if its repairable after a spun rod bearing, but im going turbo build, so how much can it handle.

just wondering, also how about the main bolts, im thinking doing arp bolts.

As far as I have seen people say 1000hp on the crank but I can't say that is for sure.
At least 700+ I'm sure someone will come in that has a better Idea.

There have been more than a few to see 1000hp.They are deff safe to 750-800hp.

ya thanks guys, i just need to know for sure. il be safe then. i was thinking a goal of 500-600. i will put in arp main bolts to hold it in real good too just in case.

Oh man 600 will be a breeze for the stock crank, the whole stock bottom end will do 500whp as it is.

Build a 347, just toss in con rods and pistons and your set. Do the 2000 arp upgrade for the rods in case you ever want to raise the boost for more power.

Am running a stock crank, stock rods, stock pistons and 98K+ miles and a 150 shot look at my sig, and its through an A4 500+ and 600+ hp on a stock crank is nothing.

Stud the mains, and have the caps align honed and you'll be fine.

izzman55

ok great, so should i mark where each bolt goes so i put them back exactly where they go then? the mains are the ones without the caps obviously have the cap on top? im very new so thats why i ask. is it expensive to have them hone aligned? and what is the process of doing that.
