The POWERDYNE Power-Plus Centrifugal Supercharger will provide 40 to 50% more delivered horsepower
The POWERDYNE Power-Plus Centrifugal Supercharger will provide 40 to 50% more delivered horsepower
and torque and do it efficiently, reliably and quietly with no loss of driveability or daily ease of operation. You can
substantially increase your vehicle's quarter-mile acceleration. This rugged supercharger's precision construction
and the exclusive POWERDYNE SilentDrive cog-belt internal drive assures full high speed performance at all
RPMs along with outstanding reliability and quiet operation.
Strengths: Very quiet, less expensive if you can pick one up used. Install extremely easy if you have any mechanical experience. No oil lines to run. Most vortech parts are interchangeable with it. Great beginner to intermediate supercharger IF rebuilt properly. GET IT REBUILT BY 928motorsports.com!!!
Weaknesses: I HIGHLY RECOMEND IT GET REBUILT BY 928Motorsports.com, if not just throw it away and start with something else. Without it being rebuilt by 928motorsports it Does not: produce as much boost as advertised. Does not have cooler charge temps. Drive belt slippage!!! I suggest the 8-rib vortech pulley setup, reduces belt slippage immensly. The belt tensioner from Powerdyne is junk, it will bend or distort if you try to tighten the belt to much. Alot of people with bad units and even worse parts and service.
Summary: O.k. this is my third post about this product in hopes to help somebody else that is/was in my shoes. If you have purchased, bought a car/truck with one already on it, or was given a powerdyne BD-11/BD-11A it CAN BE a good unit. But you must get it rebuilt or serviced by 928Motorsports.com out of Wisconsin. The pros must out weigh the cons if you decide to keep your powerdyne. The parts and service for the powerdyne can seem expensive but look at it this way does getting it fixed right the first time (or how ever many times you tried to get it fixed by somebody else) less expensive than purchasing a whole new supercharger setup, plus having to install it.
My point to this post is to tell you that the powerdyne can be a good peice of equipment. Is the powerdyne a superior peice of equipment, NO. But it can be as good as SOME of the other units out there for a fraction of the cost. Will it perform as good as other products? Yes if you have the right service/rebuild done to it and properly tune your vehicle for it. But know you will be limited on how much boost you can produce. 928 has an impeller speed calculator on thier website to help you determine what pulleys you can use to produce max boost out of your powerdyne without having bearing/belt failure. without a proper rebuild on the unit you are limited to a peak impeller rpm of about 36,000. If you opt for the "super" rebuild as i did you can enjoy a peak impeller rpm of 48,000. To put that into perspective a Vortech V2, V3 & V5 have a peak RPM of 52,000 depending on trim package. I am only hitting about 45,000 rpm with mine and i'm making 10psi of boost. So what i'm saying is the powerdyne is a very capable unit, but you have to remember that it is internally driven by a belt so you have to expect a failure eventually. Have i had a belt failure since the rebuild? NO. Do i drive my car hard? about 50/50.
So if i could do it all over again knowing what i know now would i do it again? Yes. Would i do it again if i had enough money to purchase a new supercharger? No, i would have bought something more capable to support more HP. Am i happy with what i have now? YES. Not to mention the satisfaction i get beating vortech charged mustangs and the look on their face when they see i've got a powerdyne.

Weaknesses: Recomend gettting it rebuilt by 928Motorsports.com. Does not produce as much boost as advertised, but is atainable with a little work. Drive belt slippage!!! I suggest the 8-rib vortech pulley setup, reduces belt slippage immensly. I give this product an overall 3.5 out of 5. Alot of people with bad units and worse parts and service.
Summary: This is an update of my previous review, I have been using my powerdyne for 2.5 years now and just had my first problem. The internal belt finally decided to let loose on me. I have taken this car to the track at least 5 times and made multiple passes down the drag strip. If the internal belt was going to go it should have gone there at the strip with that hard shifting there. I have also recently installed a boost guage on the car. As i suspected the powerdyne does not produce as much boost as they claim. But since then i have sent it off to 928Motorsports.com for a rebuild. I opted for the "super powerdyne rebuild". A little on the expensive side but cheaper than buying a new supercharger. They install better high speed bearings pre-lubed with better higher temp synthetic grease, Put a new hardened steel impeller shaft, install thier own patented high speed billet impeller, and vent the case, and shim the impeller for better efficiency. took about 2.5 weeks for turn around. Got it back threw it in the car and went for a drive. I was impressed the supercharger brought boost in sooner (3,000 rpm) and pushed 6.7 psi with the same size pulley as before. Where as before the rebuild it was barley getting 4.5 psi. It does make a little more "turbine" noise while driving but no where near what most other superchargers do. If you have a loud exhaust on your car you wont even hear it. I am happy with the powerdyne with the "super powerdyne" rebuild on it from 928 Motorsports.com If you have a powerdyne and cant seem to get anything done right on it check out 928's website and give them a call they might change your mind. I am not here to tell you powerdyne is a superior product but i will say that with the right parts and service it can be a good peice of equipment for the money. If you want to run over the 12+ psi you might want to consider getting a gear driven supercharger such as procharger or vortech. But After the rebuild it will support 9-11 psi with the right pulley arrangement.
Strengths: Quiet with no whine.
No oil lines.
Some horsepower gains.
Weaknesses: No cooler or denser air charge.
BD-600 is unreliable junk!
Warranty is a joke.
Customer service is useless.
Summary: On August 11 of 2006, I installed Powerdyne's K10526-201 on my 2002 S10 Xtreme. This kit consists of JBA headers with gaskets, fuel management unit, plastic intake tubes, BOSCH bypass valve, crank pulley with spacer, serpentine belts, and the BD-600 supercharger with mounting brackets. As typical with Powerdyne, they shipped me the wrong headers; the ones for the C2500 Silverado which will not fit within the S10. After a long 4 week wait, the correct headers finally arrived. Once the install was completed, my S10 increased in horsepower from 151 to 235 at the rear wheels. On September 3 of 2007, shards of the inpeller fins were blown into my engine, destroying several cylinders! I replaced the Vortec V6 and of course, Powerdyne would not honor their warranty. So I dissembled the BD-600 myself to find that the tips of the impeller fins had been sheared off, the impeller shaft was bent, and the puny roller bearing on the impeller shaft was completely worn out. NEVER BUY A POWERDYNE!

Weaknesses: It's weaknesses are well documented here, repeatedly. I can't add any new ones, just nod in agreement.
Summary: I was searching for new (better) bearings for my BD11A (which is on the bench), when I came across this forum. I can only echo the agony of owning this product that are already posted here over and over. Mine is just over a year old, very low mileage and never raced. The ceramic bearings are gone and Powerdyne tech support doesn't exist. I say this with confidence, because they don't answer. However, I have a feeling that, if I wrote to buy a new one, there would be a reply immediately. Caveat emptor boys and girls.
Similar Products Used: None. This is my first experience with a power-adder. I like the concept, but chose the wrong supplier.
