Anyone have information about these pulleys?
The Speed Inc. looks damn It also appears to be lighter in weight.
I'd almost buy it based on the looks, but want to be sure there have been no problems.

I havent heard of anyone using the Speed Inc pulley, I havent seen it before. Many people use the SLP pulley. Most use the ASP pulley simply because it works. I love mine, no complaints.

Has anyone tried the Fluiddamper Aluminum Dampers?

I have been using the March Fluid Damper 25% under drive pulley, but I have temp problems in the summer while idling/driving in traffic. I had no problems with the stock pulley. I just bought the Fluiddamper 10% under drive pulley and am going to try it. I was just wondering if anyone else has tried one?

The real key is when you add your underdrive pulley you need to add some Redline Water Wetter at the same time. That's what I have done on every car I have added an underdrive pulley to, and never had a problem. It is cheap, and it really does lower your water temps...just don't expect a miracle. It's probably good for 10+ degrees F.

Id go with the ASP, its pretty hard to see the pulley, so does it matter what it looks like? I know some people go with March, but ASP has been proven to work with no downsides.
