powerdyne superchargers?

Powerdyne is not out of business, as a buddy just bought a newly designed impellar from them for my old PD that I sold him. I had a race rebuild done to it by 928motorsports, and with a 7" crank pulley and 2.75 blower pulley on a stock long block it made 12lbs, of boost at 5500 rpms. Before it was rebuilt by 928 the internal belt broke 2x, then I sent it out for the race rebuild and it never failed me again. My buddy now runs the same blower on on his 331 with AFR 165's & E-cam. He is running an 8" crank and 2.75 blower pulley. On that motor he makes 12lbs at 5500, but has belt slip issues with the 6 rib belt. There is another company the he used for his old PD that had good srvice also. Typically it is the internal belt that fails and you can buy the full kevlar belts for 50 bucks online, and change the belt while the blower is still on the motor if your good. The guy with the 331 made like 450rwhp and close to 500 rwtq at Kauffmans Motorsports. This was done pulling the motor no higher than 5500 rpms.

From what i've read, powerdyne at the beginning of this year was bankrupt and being purchased by another company.
929 tried to fix my buddies, then said it could not be repaired.


Here's some powerdyne reviews.

Do a search. All I can say is, mine was the biggest POS, EVAR!

hey guys, my dad was actually the guy looking into buying the powerdine supercharger and we never really heard anything about the brand but we did some research last night and i guess the belt in it comes off and you have to send it out for repair well the kid that wants to sell it took it apart (not sure why) and he said he just did it to do it and he "lost" the belt but i think the belt blew..

were not gonna buy the supercharger anymore but possibly the motor..

I wouldnt buy the motor either considering he's lying about the blower.

I have a very old BD-10 and have had to replace two belts in it in the last five or six years. Personally I don't think it's that big of a deal. Powerdyne wanted a ridiculous amount of money to rebuild the thing, so I took mine to a local machine shop to pull the bearings. I don't think they charged me more than $40. The top bearing sits right on top of a guide washer for the belt, and the lower bearing is in a blind hole so a regular bearing puller won't work. Taking the supercharger on and off is like a 15 minute job; just remove the serpentine belt and the 8 or so socket heads.

Here's a couple of links to rebuild kit vendors, but you can also find kits on eBay

I bought my rebuild kit from a guy on eBay for about $100. The belt is a proprietary Gates belts so regular HTD belt distributors will not carry the correct size.


BD-10 at 6psi, with Performer intake and heads, and TFS-1 cam. Dynoed at 342 hp and 335 tq at only 5500 rpm. Should be a bit over 350hp at 6k rpm.
