+1From what I've seen the pullies really help to make the car rev quicker... I've done some testing with both an M5 and M6 and it works great. There are a few companies that make them and they are pretty much all the same from what I've seen.. 20 - 24rwhp increase..
Shameless plug!!!:1:rpi is the only way to go.
Is this what you are looking for?did either of you install yourself? i posted on m6 side but no feed back
I will be doing this within the week. I will post observations.Anyone switch from the Evosport to the RPI pulley?
Keep us updated, pros/cons of the switch. Any difference?I will be doing this within the week. I will post observations.
:cheers:
Nero told me he had another m6 getting a pulley done this week. Get a before and after dyno if you can.pulley being installed tomorrow
Very soon. Since I just got back from oversea, the noisy sound in the morning still not bother me that much. When it does, i will let you know. BUt I don't expect any different in hp number or feel, just to eliminate the noise i experienced. But it worth putting them on dyno jet just for fun.Anyone switch from the Evosport to the RPI pulley?
Same diameter, RPI just slighly lighter than Evo and OEM color instead of black.Sorry if this has been asked before but is there any diameter difference between Evo and RPI?:dunno:
Kenny, what pulley noise are you experiencing?:confused2
