You mentioned 8 lbs of boost up top, and under 20 lbs at the bottom. I think this is doable as long as your willing to turn the boost up some. Doubt you’ll get to 700 wheel at 8 lbs…might take 12-15+. The Gen5 stuff is crazy efficient.

Sorry let me clarify, I am running 8 pounds now with a bone stock motor.
I was thinking of a 20 lb max after the rebuild with a new upper pully and a boost controller.

I am picking up all my other stuff from them (rods pistons oilpump) and they are doing the porting. they have a turbo cam and a low lift cam and High lift cam for the l83 but no supercharged cam per se.
BTR on the other hand has a superchanrger cam

Ok gotcha. You should have no problem at all hitting 700 wheel.
