Same combo I have other than I have 9.6:1 compression and a 76hpq turbo. If you have a 70 q trim, you should be able to go mid 9's no problem. You are losing alot with that converter.
It's hard to say exactly but the 76p in a .63 precision housing is good to 136mph in decent air. Maybe 136-138 in really good air. The 70 compressor will support more than the 76p will. With increased CR and the cam profile and timing optimized you can squeeze more out of the small ex wheel. I'd expect 135mph out of it the way it is now. The converter is probably eating 2-3mph out the back. The boost level doesn't really matter. You will hit choke flow at the same mass flow regardless of the actual manifold pressure. You are getting close to that point. You should be picking up 27-28mph out the back.
