I'm soon to build a FI setup and hope to make about 750 to the wheels. I am looking for info on how much a stock LQ4 crank can handle.

 

im sure more than that.. you goin to do good Rods and Pistons? ive heard the stock crank can handle 1000.

 

If your going to put the time, money, and effort into building a monster like that why not put a good solid crank in it? To be safe I would put a good forged crank in! I would rather be safe than sorry

 

I understand. I really can't spend $2000 on a crank though. I'll just have to not have as much.

 

I am doing rods and pistons. I talked to John at Wiseco and he hooked me up on some info. I have been told 1200 motor hp on them. Then someone told me 600 hp. So I'm not sure. Does anyone know if anyone is running above 750 hp?

 

stock48 put down 712 to the wheels on a 6L stock crank

 

My buddy has an lq4 with stock crank, forged rods and pistons and made 840 to the wheels with no problems...

 

Anyone had any luck in the mean time with some big HP numbers.
