This is why they make GREAT paper weights lol
I was surprised when you said that you could get 1400 deg with a 4911 up half a turn. Both of mine that were turboed (banks kits), and both with the same 4911 pump (cranked) wouldnt go over 1200.
The first one I had would hit 15 psi pretty easily, had a turbonetics super V compressor and a .96 exhaust housing, ran really hard and eventually had an engine failure. It was in an 84 3/4 4x4 burb, and it was a rocket.
The second one had the standard banks turbo with the h trim compressor. it would boost a little quicker but only make 10psi.
