I just ordered a 3.1" RR pulley thru Lethal Performance. Hopefully it'll ship out in a timely fashion.
Strange that the Reichard website has been taken down ??

I don't think it is the holes that make the difference...rather the cross cut slots that actually grab the belt...or so the man himself says.
Thanks for the lead. If the email address you're referring to is 'reichardracing@yahoo.com', I've already tried that.
I went ahead and ordered the RR pulley thru lethalperformance.com. I'll have them deal with RR instead of myself making unanswered phone calls. Hope it arrives soon! They stated that is should ship within a day of order (which I don't believe)

Update. I had a new crank drive pulley made, from the guys at ASP Racing 
I sent in my 5.45 SOS crank pulley and asked for a 6" version. About 4 weeks later it has arrived. Fit and finish is absolutely perfect. I paired this up with a RR 3.1" pulley and should be good to go. The 6" crank and 3.1" blower pulley gets me pretty close to my previous setup of a SOS 5.45" crank and 2.8" blower pulley. The new pulley is a tad bit faster, as far as RPM goes.

They charged me $150 which is a steal. 
If you're interested, I'm sure you can give them a call and they'll fab one up. Since they have all the engineering design complete, it should be very easy. You can mention my name (Arax) to pull up my file.

Some high-end industrial v-belt drives also have grooves cut in the ID of the pulley. This prevents air from being trapped between the belt and the pulley at high speeds. Notice the upsets on the inside of the pulley in this picture. You can see the holes to let air escape.
Edit: The picture wouldn't hot-link, so here's a link to the page it's hosted on. Click the pulley for a bigger image.

That is a steal. If I dont blow my motor with the fuel issue Im having, Im going to give them a call.
So if I stayed at my same SOS 3.4" Charger pulley and added this pulley would that be equivalent to say a SOS crank pulley and a SOS 3.1-3.2" charger pulley?
BTW: Thanks for paving the road for the rest of us with this new crank pulley.

Im running a custom ASP crank pulley on my SOS setup, Paxton 1500 with a 2.7in. I have to run so much belt tension I keep snapping belts too. My pulley are steel, and are smooth/non textured. I actually am going to try the Carbinite coating, will have my pulleys back (2.6, 2.7) this week. I do roll street runs, no track. Hopefully it helps. Next stop is cog...

I tried the Carbinite coating myself and it's crap. Your belt will shred, create dust everywhere then snap. I was running the stock 5.45" SOS crank pulley w/2.8" blower pulley.
