superchargers?

[Gumby1008]

I think i still have video of a once local turbo hill climb car, no slouch but not for the faint hearted , i think he fixed the lag problem by not backing off ,, race to the sky in NZ
Sprintex in WA may be your best source of info on twin screw superchargers, i think a few in the US have tried them but in comparison to a turbo or the rotrex/paxton/prochargers there is a lot more heat /psi
Hayward engineering in Leongatha fit rotrex to hill climb cars and make drive systems for them, Brett builds and races the cars, and may be a good source of info too
sounds like fun, come back and update us occasionally

that would be so scary, not backing off on a hill climb.
but yeah currently the two that I have found are auto rotor, and Lysholm.
I only found auto rotor because they are used on minis and im guessing that you can give a busa engine more air than a 1300cc mini engine. I completely forgot about sprintex, I think that's the kind that is made by a guy around the corner from my mates work, they are way over priced, for a full kit I mean. Intercooling is still possible, and not that difficult. Twin screw is better than roots for staying cool, marginally, but centrifugal is way better than both. Only problem is that we want the power all the time. that's why we would prefer to avoid rotrex
