It will drop 0.1/1 mph consistently.
The SLP underdrive pulley says it has the taller walls to prevent belt slippage... the march pulley is the same pulley as the SLP Pulley...
Pulleys give you extra horsepower mainly because it is a LIGHTER pulley, not because its smaller.(or so i've heard)
If you have an A4, u would want to get an alternator Overdrive pulley, which is like an extra $30 or so and u can get it same place u get the underdrive pulley. Some people with A4's do not use the alt overdrive pulley and are fine, but most recommend it.
WIth a manual u generally don't have to worry about low power from the alt, unless ur running a system.
Whatever pulley you get, make sure it is SFI approved, i believe some of the earlier ASP's ones werent? someone correct me if i'm wrong.
I recently ordered the SLP one, and its a very nice looking pulley, being aluminum.

Yes the pully is lighter because its smaller, but as Zeus stated earlier in the thread, the power comes from the pulley being 25% smaller than stock. That turns the accessories slower and allows more power to the wheels.

So if my car (M6) is my daily driver, and I drive around D.C. in bumper-to-bumper traffic... should I rethink this whole pulley idea?
I was going to get the 25% crank pulley and the stock Alternator pulley.
What do you guys think?
Should I stick with the stock Alt pulley if I'll be sitting still in traffic? Or should I not get the pulley at all
