Just wondering if anyone has any experience with DM Motorsports Pulleys?

Here is a link to the pulleys

RX7 Billet Pulleys

 

dm motorsports is a Company based in the UK... I think you will have more luck ti ask the guys from mazdarotaryclub.com (UK based Rotary Website)

 

Also, prices will be pretty high since the dollar is kinda weak. There's another thread somewhere on their pullies, I don't think anyone has tried them yet.

The Ebay pulley kits work well, I have no complaints with them, and I've installed 2 of those sets. Good price, too.

I'm not sure on their airpump idler pulley, I don't see how it installs. The Pineapple Racing pulley is a really clean, proven design and is worth going with.

I was going to go the ebay route. The touge fatory ones, but I have only seen underdrive crank pulleys. If touge factory had a stock size pulley I would be all over it, because they are priced really well. DM offers the main crank that isn't underdriven. I also talked to SR Motorsports and they offer a size that is 1/4 inch smaller than stock. The good thing about the DM pullies is that I can get all the ones I need in the same color also. I am replacing every pulley except the AC because I am taking the AC out. Then there is always Super Now pulleys, but they are also pricey. i can get the entire set of the DM pulleys that I can 3 from Super Now.

 

The Ebay touge pullies are a VERY conservative underdrive pulley. It's underdrive *enough* and doesn't run the alternator super slow at idle.

If you're doing pullies, you wanna do underdrive, that's half the reason for them. The SR pullies are nice but HORRIBLY overpriced.

I'm waiting for my IRP higher amperage alternator to shipped. What type of effect would the touge pulley have on the high amperage alternator or any crank pulley that is underdriven for that matter? Thanx for ur input btw

 

I don't *think* a higher amp alternator will help with a serious underdrive pulley. Typically it just means the alternator can produce more amperage and service a higher load, but alternators typically need a minimum amount of RPM to generate a certain *voltage*.

Yep, they're good, seen them in person on a couple of Fd's and I'll be putting a set on mine
