Adriano917 · 06-19-2019, 08:06 PM

there's a lot of threads and debate on this. go to search bar.

I installed a used one about 7 years and 50k miles ago.

Sure, but the Dinan one is very hard to install. Go with the Macht Schnell or Turner.

Soooooo true. Getting a virgin belt on the Dinan pulley must be such a PITA since getting the belt on with 30,000KM on it still suuuuked.

I have the Macht Schnell pulley sets and have been really happy with them. Macht Schnell is the only one with both the crank pulley and power steering pulley set. Could tell a difference right away after I installed them. Not to mention easiest to install.

I had Dinan it was ok, install didn’t seem as bad as people made it seem.

i have AA Pulleys by BMW TUNER and have been good to me!

I say, it would free up perceivable power but not sure if you want the water pump to be under driven, especially if you track the car.
Maybe get a larger/upgraded radiator first...

At 7000 RPM, an under-driven water pump will make allllll of the flows you will need.

Happy with my Dinan pulley and would do it again. Haven’t noticed any downsides in 25k miles.

Bought a used MS pulley and installed it when I had some maintenance done. Car seems to rev a little faster but that's it. Dont expect much but it's worth it at used prices.

I spend a lot of time in traffic (low rpm) in hot weather. Would underdrive pulleys affect my air conditioning, or make the power steering work harder at low rpms?

I did mine and an aFe power intake, the two combine help open up 20 horse puppies! It was worth it to me to do it, plus gained approx 2-2.5 MPG when cruising on the hwy for long distance as a side benefit.
