Pulley Mod Who Makes the Best?

I have a Dinan rear section muffler, looking to do the xpipe soon too, but that is going to be expensive since I need to also do the o2 sensors and all that bs to keep my check engine light off. Anyways I want to do a pulley system to add hp which should be significantly cheaper than the xpipe set up which is next. Who gives the best bang for your buck for a pulley?

Active Autowerke makes really solid performance pulleys that claims gains of about 10-12hp. Definitely something to take into consideration.

I'd go with Macht Snell or Active Autowerke. Can't go wrong with either IMO.

Most vendors offer a replacement crank pulley only, Macht Schnell and Rogue utilize a dual pulley design and use standardized belts (rather than proprietary) which can be found at any auto supply warehouse if replacements are needed during maintenance time.



Dynorun 21: Baseline
Dynorun 33: Macht Schnell S65 Performance Underdrive Pulleys, OEM Intake, Stock Exhaust

More info on this dyno session can be seen in this thread: http://www.m3post.com/forums/showthread.php?t=567651

The Macht Schnell pulleys also allow the AC compressor to not be underdriven, since the clutch disengages at wide open throttle (WOT) and provide a considerable amount of power throughout the entire powerband.

If your thinking about doing other Dinan parts you might as well get their pulley. That's the route I went.
