why not see how the 650 tune and car perform before making the huge jump?
do you have a full exhaust system and is your subframe/trailing arms setup correctly? i'm against methanol but have you considered that or a fuel system on e85? unless you are going for a 1/4 , 1/2 or mile records the 10psi realm is risky.
