I posted a thread some time back asking the same thing. The pulley must be steel to apply the coating. Some of the guys here have media blasted their aluminum pulleys and then had them hard anodized. They report less or no belt slippage, So, if you are experiencing some slipping, this could be one way to help, but you will need to buy the steel pulley and coating.

I sent them a new 2.8 8 ribbed pulley for my tvs2300 last week. They called today, ready and shipping.

I will post up my thoughts after I have installed it and tested.

Thanks for the link. I wonder how long it lasts on a daily driver. It gives me hope that an 8 rib setup can spin an F-1C without slipping.

The claim from Procharger is that the current head unit pulleys are already hard anodized.

If they are hard anodized doesn't that mean they are aluminum then?

Yes, it was more to the point someone posted above about some people media blasting their pulley then having it hard anodized.

Bead blasting the surface of an aluminum pulley will remove the hard anodizing. You need to have it re-done. Here is the thread I mentioned.

So the bead blasting roughs up the surface, then hard anodize over that for extra grip? So the Procharger pulleys that are just hard anodized wouldn't have the grip of a previously bead blasted pulley?

I am just reporting what others have done. Most pulleys are black anodized aluminum. The anodizing evidently adds strength to the top layer of aluminum. So, when you rough up the surface it removes the stock finish. I guess we need a metallurgist to step up and give us the facts.

I called them today and they said they have started coating the aluminum pulleys now.

Both Vortech and Procharger anodized their pulleys, but neither are doing hard anodizing. It is a different process that yields a much tougher coating. For example, when I bead blast a Vortech anodized pulley, it is like waving a magic eraser over the pulley - it's black then you hit it with the beads and it turns silver as the coating immediately is removed.

But I had to clean up a hard anodized pulley after it was damaged by a bolt, and it took 10 minutes to wear through the coating and fully clean the pulley with the bead blaster. A regular one takes about a minute to do. After 6K miles, I can't detect any wear on the pulley that I had hard anodized. And it is a grippier surface since it is matte and not glossy.

FYI, there is a similar process for steel called alodining, but I don't know if there is a hard alodine surface, nor do I know how tough the alodined surface is. Never used it.

I had a 2.8 TVS pulley coated. There was less belt slip than with a non coated 2.9. However when it did slip (low RPM, high load conditions) there was belt dust EVERYWHERE. Now Im going to an 8-rib.

They're basically making your pulley grooves sandpaper. It's going to grip, but god help you if it slips.

I got the two pulleys, I sent in, back from carbinite racing. They work great. Fast service from them also. Ill post up some pictures later on.
