10.2 compression and boost?
10.2 compression and boost? Is this just a dumb idea or would it be ok 
I am looking to make around 700-800rwhp. It is a forged shortblock. The car makes about 450 rwhp on motor unlocked with a PT4000 
I am looking to make around 700-800rwhp. It is a forged shortblock. The car makes about 450 rwhp on motor unlocked with a PT4000 Would 10lbs get my goals I figured it would take at least 12-15 I just dont want to have to fill a bottle up everytime I go out which is like 2-3 times a week 
What size turbo and intercooler would be best for my setup?

you'll need 10-12lbs to make 700+. On 91 I made 641rwhp on a stock head/bottom end at 9psi. A forged block will better handle the pressure of 10-12lbs of course, and make sure there's no detonation. If tuned properly, you'll be good to go on pump gas.

I would like to line them up if you dont mind. My car is coming soon.
I agree about swaping heads to so bigger chambered heads like the LQ9 that have 72cc combustion chambers. That will lower your compression by almost 1 point then you can boost to 15psi no problem
