Anyone in here try or heard of Rotrex Supercharger? I heard it's very quiet and reliable. Here is the link http://www.rotrex.eu.com/body.php. I think HKS is using these unit at the moment.

george said:hey lex thanks for the nice words. thats my car by the way. i already have headers on it with a full twin 2.5 inch exhaust. im running 440 injectors and a walbro fuel pump so the fuel system is good for much more power. to get it up to 15 psi i am having a custom crank pulley made up either 7.5 or 8 inch diameter. the belt looks stressed becaused it was damaged as i was testing the system (the supercharger wasnt 100 percent in line with the crank pulley). cobra i cant machine the ribbed pulley you are talking about because the ribs actually make up the pulley. if i was to machine them flat the pulley would fall apart. to achieve 15psi all i would need to do is move the supercharger forward by about an inch and install the new crank pulley. Not a big deal reallly and well worth it, on 15 psi it will make a massive amount of power. by the way the car made 206rwkw with a restrictive exhaust (fixed now) and with the auto abou to slip (had been on the dyno for about 2 hours) should make more power now
You're already at the manufacturer's speed limit (100000 RPM).ismo67 said:In my setup there is an extra aluminium pulley on the top of the crankshaft pulley. And the Rotrex has already the smallest one available from Rotrex.
So, maybe machine 8inch pulley and adjust the pressure with Rotrex pulley?
But that's after I have forged internals?
So, making the motor flow better is still the issue here in this setup...turbotwig said:You're already at the manufacturer's speed limit (100000 RPM).
