I was suprised that the whine was so much more than the 181mm, but I would say
nearly twice as loud in a good way, and off part throttle vs mid to full throttle. If these things can be kept cool their gonna be monsters.
I'm guessing that car had a needswings intake(or something similar)? I have SL55 setup and you can barely hear the s/c under WOT and inside the car.........outside it's just a quiet silver/blue blur going by. LOL
