The main problem is that the overall ratio is changed due to the lighter weight. Some companies will try to compensate by using a larger pulley. I have no idea if that works. The result is that you have to buy custom made belts that will work properly with your pulleys. I believe UUC supplies the belts with their pulley kits. In a lot of Japanese cars such as Hondas, I have seen a lot of cracked aftermarket pulleys. Reliabilty would seem to be an issue. The material used to make the pulleys is very important. That also affects the price, as you can see they aren't cheap.

TMS pulleys

The reason you don't see too many of these installed on BMW's is that I find most BMW owners (around here anyways) are not really performance oriented or properly informed. They don't do research on modifications, but rather buy into hype. $400 intakes anyone? Compare the ratio of people who drive BMW's to Honda's who actually know how to tune for a/f ratio and actually know what they're doing. Most BMW owners I have met want to install a mod then forget about it, no tuning or calculation whatsoever. I recently met a fella who told me he wanted to convert from OBD1 to OBD2 because it was newer so it must be better. WTF, please people, understand what you're doing to your car before you do it. That's almost as bad as the guy in the other thread who wanted to convert from manual to automatic! :lol: j/k

them. If only we could tune out airfuel ratio. I was looking around at some stuff about TBs the other day, and I saw some valves that looked like low and highspeed adjustment you might play with those to fix your idle.

I'll post up some pics I have of a spare TB sitting in my basement, please help me identify what I should by playing with. Also, I've heard that my idle could be self-adjusting because of my Dinan chip. Can anyone confirm this?

Kev, I haven't forgotten about the Dinan dyno sheets, I'll get them up asap.

Taking the load off the engine is a great way to free up power. Just make sure when you use lightweight parts, make sure they are made of high quality and very durable material. Highly recommended modication. I removed the stock belt driven clutch fan which was attached to my water pump pulley, made a world of difference.

I had a less-noticable effect with the removal of the belt driven fan. Revs a little quicker and better MPGs but little on the straight up acceleration as far as I know.
