Rotrex superchargers.

Interesting, they will also re-grind your 944 cam. They seem to have several prices, might give them a ring tommorow.
 
TTS been around a long time.They started doing bikes 30+ years ago & seem to have evolved.
Centrifugal superchargers are very popular in the US & the Rotrex has been used on an Elise conversion amongst others.

I'm using a Vortech from the US for mine. Max BHP is around 850 on this compressor build.

Their cams look OK but to be honest I'd tried Dave Newman in Farnborough.
 
Great work Jim and thanks for the camshaft source. If I get cams for my lux I take it I'll need the DME re-mapped. I think it would cause problems when the DME is injecting based on RPMs at WOT where the cames would change the air flow.
 
TBH it would be a cam on an 8V ;-)
Yup the DME would need remapping, bare in mind that the DME fitted to a 944 is a relatively dumb device compared to current ECU stuff.
My S2 lump came without a loom or DME so I'll probably go for an after market management. Debate at the mo is Emerald or Megasquirt. Assuming the cam has more duration & overlap then the fueling could vary considerably, assuming you don't go mad then a good mapper could set up the original DME to suit.

Remember a 1984 doesn't have a removable "chip" so it isn't easy to replace it with an EEPROM
