Hi Michael,

The supercharger is a Rotrex, from a Danish company called Scanpower 
(http://www.scanpower.dk/). I think that they have resellers in the 
states...
It's driven with a poly-V belt (the wide one) - rather easy to install if 
the engine is equipped with poly-V from the start, mine wasn't. Anyway, the 
pulley on the generator is replaced by a new one, so that the supercharger 
is driven from the generator (there is now two belts on the generator, one 
driving the generator - the "original" main belt - and one driving the 
supercharger, going from the generator to the supercharger...)
The chip is standard, but I have installed a extra fuel injector, controlled 
by a MapFueler - this one needs to be calibrated with the car on a 
dynometer.
Finally I installed a intercooler (from a 325td), and a KN performance 
airfilter. Rest of the engine is standard. The exaust system is allso 
standard apart from the rear muffler, which is replaced by a Sebring.

I'm planning to have my clutch upgraded (it is slipping under hard 
acceleration). Allso I'm considering a final drive from the 325, which 
should raise the top speed to 250 Km/h! Finally I'm thinking about replacing 
the cat to the one from the M3.

I'm very pleased with the performance of the car. But as allways when you 
modify something on your car, you'll run into problems... But until now, the 
good have defeated the bad...

Regards,
Thomas.
