Come on guys. Someone help a newbie out.

Unless you're running alky one fuel ain't enough to keep up with that combo. It should have a double pumper in it. Also needs a good strong tranny. Ther is enough good parts in that combo to go mid 10's in a well prepped car.

It has an alky kit on it but he said he doesnt use it. He said he uses c16 instead. Should I be worried about the bottom end? He said the car went 11.20.

I went 11.20 on my stock bottom end at 23 psi. I did not get to crank the boost up for the real pass because I got booted for no cage. The stock bottom end should hold as long as you dont detonate. The higher the boost you are running the less tolerance the motor will have for knock.

Looks like a good combo for some mid 10's like Steve Hughes said with the right boost levels. Of course I have stock heads. With some good heads like you have you shouldnt need a crazy boost level to get that 10 second slip.

good combo , at 20 psi you might be ok but at the limit on single pump ,after that alky will help with extra fuel , you should not worried about bottom end , 4 steel mains are good enough , two center ones would be enough to go deep into tens, tune of course - 0 knock is a clue , if he says he only used c16 to go 11.20 that is a good thing ,car can go much faster with this combo .one thing here , if you don't have already I would invest in WB set up , or MAF PRO or FAST , something to read ,or even better control tune with WB / AFR sensor :wink:
