Message: [QUOTE="NyCowboy87, post: 1519074, member: 1776"] Something to consider when sizing compounds is the size of the high pressure charger turbine wheel compared to the compressor side. Also turbine flow of the hp turbine is crucial too for back pressure purposes at wot. I ran a hx55 with a 80/76 turbine and a 66/98 compressor and a s4t which has the s500 turbine and a 86mm compressor with a 1.15a/r housing and 400/200’s with swamps tuning. Truck ran great and drove like a stock truck if you wanted it to. Very little smoke and could have thrown the egt gauge out the window. Would run 65 psi in a light street tune and about 95psi in the drag race/pull tune. That was with no wastegates either.
