Need To Sell!!
i was going to go 12 or 13:1 also but with the boost you will be somewhere in the 19 or 20:1 so you will run out of octane. you will have to run race gas all the time to get it to run good on top end. im running into that problem now with 10.5:1 im running 100 b\c after 5500 i dont make anymore power with 93 it just levels off and stays there. so good luck.
