Compound Procharging!

[overZealous1]

i have only seen turbo's feeding a supercharger before. was going to do this on another project and did quite abit of research but never got around to doing it.
plan was twin turbo into a 6/71 huffer. it had been done years ago by rick dobberton. i contacted him directly to see his findings. with the turbo's feeding the blower, whatever your turbo boost is set at, will be multiplied by the blower boost in theory.
i would assume the same to be true for a compound supercharger set up, but would imagine effiecientcy losses to make it a loose theory.
i would try to contact racers who are doing it and get more info. if they wont give up their secrets, procharger will to sell ya the parts!! haha

Regarding asking the racer himself. I did just that and he stated that it cost them a lot of "blood, sweat and tears" to develop the system..

Unfortunately Procharger are not as progressive in the racing scene as they are with the "bread and butter" street scene. They only developed a gear drive many years after the Supercharger Store launched theirs. Also Procharger do have a gear drive now but only for the F3's on BBC's.

My thoughts were as to wether a smaller gear set on one side of the twin gear drive hence spinning one slower with meth/water injection in the pipe between them and in the intake of the first blower. Then finish with boost control on the charge pipe. It should have twin screw performance at the bottom end with ultra high boost on the top end!!!!

This would be using all the components of my existing twin parallel set-up with just a change in pipe work and gear sets.

When studying the Promod car it appears they have one standard rotation F2 and one reverse rotation F2. this indicates a fourth gear set in the twin gear drive meaning the step up ratio was quite drastic. But then they are identical blowers...


Obviously they didn't go with an F3 and and F2 due to flow issues or they didn't want to go staggered due to the Pro mod packaging issues...

Yet twin F2's didn't allow enough difference in speed without and additional gear.

Just to clarify a single input (from the crank) gear turns two other output gears (to the blowers) either side of it. If you add a fourth to either side you reverse the rotation!!!!
