How good is stock LQ4 crank? I want to make 12 or 12.5:1 cr and turn it to 7000. In the end it will probably get a 200 shot of n2o.

 

it'll work...for a little bit.

 

agreed...thats a lot of stress on a stock crank. I'm sure people are going to come in here and say it will hold 1200 HP+ and it's fine, but when it comes down to a major engine component and someone else's money, I'll recommend upgrading the crank every time on semi extreme setups.
