58cc head, how thick is your gasket, what bore is the gasket, and finally, what is the cc of the piston?

at that weight the car shoul fly. im sure im 3300+ and get 104 so i would think you could get up to at least 110

If you have MS excel you can download a CR calculator from my website.

If you don't have excel it won't work.

How have you lightened the car?

Be sure to get the C&L cal'd for the injector/EEC/MAS (the black sensor) combo you are using.
I have some C&L stuff on my site as well.

I have no idea how to estimate your power level.

good luck
