it changes the pulley ratio's for the belts that run off the engine to power things such as air con and power steering. but the air con and power steering and alternator etc still all work fine. but yeah it does give around 7ish KW 's back to the engine to send to the wheels
These underdrives work very well, close to the best "bang for buck" for the BA BF and FG Falcon. The guys on Ford Forums love the underdrive. Find them on cheap on Ebay.
the sound of an XR6 on the dyno is copyrighted now???
