Here is a vid of an M90. Listen to the 47second mark

YouTube - Intoxicating Sound of a Rouscharger

It wont. My best friend has one of only a handful of supercharged RS4's and its using an M90. It has a pretty sick whine to it especially when you hear the car coming at you. Good news is - I had the pleasure of riding in a Rotrex powered M3, which looked to have the identical unit as mine, just days before I completed my kit and it sounded awesome. Its alot more stealthy sounding but during every shift you can hear the bypass valve giving off a sort-of 'laser gun pew pew' sound (ROFL). One thing we all agreed on was that it still sounded amazing, so worry not people...worry not.

My buddies RS4 for ref... http://www.youtube.com/user/kryptoni.../4/sGKvHUpzMjk He made the video for his forum so its very detailed...just skip to the 8 min mark and you'll hear it. Same as that mustang. Ours wont sound like that, but he also heard the M3 and loved it...

yeah there wont be any awesome gear whine with the rotrex, and as for comments about a stillen blower blowing a seal on track it's a vortech head-unit, stillen doesn't make it they buy it with a custom label riveted to it, and the vortech head-unit is usually very simple and reliable. on the same coin i remember when rotrex units first came out and HKS used them for their 350z supercharger kit due to the "awesomeness" of the variable ratio steel roller friction drive, and they had nothing but problems with them. The superchargers themselves should be marked for or against the manufacturer of the head unit not the company making the kit. Personally i hate all variable displacement superchargers so i could really care less about either one. The M90 is a beast up to about 350hp after that its adiabatic efficiency shoots through the floor and you better have the worlds most awesome intercooler and an amazing exit port job.
