Interesting turbo set up

[Lids]

a thread just started on the samba, anybody with any info on this?

[richie]

looks like a pro charger to me, crank driven super charger, takes a lot to drive it though

cheers richie

[dannyboy]

isnt this why superchagers arnt common for vw motors? it takes to much power to run them up? or am i talking crap again 

[Lids]

looks the bollox though.

Perhaps they should now fit supercharger and turbo, best of both worlds.

It does, but for me packaging is proberly the biggest problem, that set up would only really work in a front engine application

I kept looking at the gold case and thinking I am sure I recognise it, but couldn't think where from, now I know

Interesting!

Surely a crank driven turbo induction system wouldn't use as much energy as a supercharger?

The working of a supercharger are far heavier in weight than a turbo fan.

Looking at the picture of there system it only uses an intake fan so that should reduce the energy required and make boost instantly.

Not sure about how fast it will spin compared to a normal turbo. Maybe its a geared set up?

Procharger uses normal gearing, rotrex uses planetary gears to multiply rpm's. Thus the boost rises with rpm's which can be problematic as normal turbo's usually reach their max boost somewhere in the middle of the rpm's. Surely stupid idea: how about to use reversed variator from scooter to drive procharger?

their dragster has made some good passes.

You guys have it pegged. We talked to the the guy yesterday at AJ Sims. It's a Procharger that's run off the nose of the crank through a gearbox.

Ok I looked at the picture again... that's me to right in the black shirt and red Vans. To the left are fellow DKK members, Tod Fuller, Nanci Mayeda and Robert Baldwin.

For what it's worth. A Miller 91 from the 20's

As above, there's nothing new exciting me, the earliest ever engines had turbos designed in from day one, they failed material wise, compounded turbos, muted next year in F1, were done in the 40's.   Turbo+ superchargers are old hat, the VW Polo is on that just now, about all we have is better control from electronics, and better and newer materials.
