but at your talking about is compounding, compounding only makes sense when your shooting for a really high pressure....like what a diesel needs, and even they tend to use compounded turbo's because of their greater efficiency. only reason you see screw/turbo compounded diesels is when they are shooting for instant pressure increase to help spool the bigger turbo
Jonbob/Pritt's/PRJ whipple GP, hasn't done over 540whp, even at 22+ psi, Tq must be ungodly at just 1500rpm....but our relatively small turbo hits 608 whp at just 18psi, and we still have a helluva Tq band
imagine the whp increase if it wasn't losing over 100 hp just to turn the whipple.
nitrous is so awesome because aside from parasitic losses of an alternator feeding the amps the solenoids require....its all "free power"
with modern turbo's running quite well even at higher pressure ratio's, whats the point of a heavy overly complicated twincharge system over a full boogie turbo.
besides, the 2300cc/140ci whipple is too small for us, you have to spin it too fast, better the larger sizes
id rather see someone bolt a 4-71/6-71 roots on, with the bug catcher turned 90* like a Quasimodo hunchback, lookin Johnny number five, looking at ya like yer a stupid human.
I award you no points, and, may god have mercy on your soul
