This MotoDyne supercharger is the First compound boost supercharger designed for the 2.7L B5 S4.

An Eaton M90 is mated to a modified extrude honed RS4 intake, the belt drive and supercharger is similar in setup to a 2.8L SC system. It matches the B5's mechanical finish perfectly. A B6/B7 s4 larger throttle body adapter is mated to the M90 to feed the large 3.25in inlet charge tube from either a single turbo setup or a stage II or III turbo upgrade. A deltagate/wastegate mounted to the intake under the path of the turbo and supercharger is pneumatically controlled and can be operated in conjunction with the turbo(s) wastegate if desired . The supercharger case is enhanced by a hi-temp black powder coat and machined finish; it's an absolutely perfect match.

The B5 supercharger makes positive pressure right off idle for smooth, powerful engine response right to redline regardless of turbo size.

Squeeze the throttle in any gear for instant acceleration. Smooth flowing runners and plenum to deliver matched power and torque. With a superior drive belt configuration of 90 percent belt wrap on the blower drive pulley there is no wasted boost under load from belt slippage or power steering cut out in bad weather due to a miss-configured idler and belt orientation.

MotoDyne engineered this supercharger to be modular, simple installation that can be completed in about 8 hours. Premium fuel is required, ECM preparation NOT included. Complete with all parts necessary for setup.

fits all 2.7L engines:
