I watched this video , and i noticed that on the manual car, the supercharger is basically inaudible. Ive seen this on a few cars where you cant hear the TVS, usually they scream.. Why cant it be heard in this video on the manual car, but easily hearable on the auto car?

EDIT.. hmm in the 2nd run on the manual you can hear it actually

 

Ya I think it has something to do with the longer gears on the autos. On the street with a full load the manual will whine just as much.

 

Buy it anyway! Holy sh*t that sounds good.
