Concider a Progressive Methanol injection system first
At 10.75 to one compression running 5 PSI you will be ok , but you WILL need to cool down that 5psi intake charge and boost up your octang level. Methanol will do all of this
I think at 5psi you will pick up some nice power , i wouldnt push it past 6 psi ,
With the methanol injection it will be awasome!
