Picked up my car today from bmw and boy were those parts guys excited!
First off let me say that the dinan vortex s/c is very very quiet. At idle you could just make out a higher pitched whine and once you steped on the gas all you hear is the exhaust GGGRRRRRROOOOOOOOOOOWWWWWWLLLLL.
I was warned not to floor it in 1st with the traction control off or I'd be suddenly facing the other way.
The installation looks very neat, the hoses are all black, not orange like in the Dinan photo.
I also got their stage 2 clutch kit. It was a bit trickly at first but I quickly picked it up. Hardly any slipping, the clutch clamps up very quickly.
Pulling out of the gallery onto route 1 I punched it in 2nd gear and I suddenly had the strangest sensation of the rear of the car wanting to launch ahead of the front. I kepted it fairly subdued on the drive home. Got a few stares from the Dinan badge. Around home its very quiet. If you keep the revs down below 2-3k the car almost sounds stock.
So far I'm very happy, we will see what the next week brings!
