Powerdyne superchargers
I'm surprised more of you guys are not into the powerdyne setups.
A few yers back (ok like 7 years back) when I got the vortech, I ignored powerdyne because I heard some folks complain about belts breaking.
Well I've been doing research recently, and went to a powerdyne setup.
The powerdyne uses an internal belt, so it's very quiet. The bearings are sealed factory lubricated units, so there is no need for an oil cooling or discharge line. This also results in a cooler blower temperature.
When I ran the vortech, the straight cut gears were noisy, and the hot engine oil made the blower hotter than it should have been.
About the powerdyne:
The BD-11A powerdyne for example, has a 3.05:1 step up ratio, with a max
impeller speed of 41,000 RPM with stock bearings. This will produce
a max of 9psi boost at around 39,000 RPM. It's max efficient RPM is around 38,000.
A company called "928" motor sports makes race parts for the BD-10, and BD-11A head units. For example, for $250 you can get a race bearing upgrade kit and kevlar internal belt. This allows for a peak operating RPM of 60,000 RPM. The greater RPM allows the blower to move more air, with upwards of 12psi boost range.
Additionally, they make an impeller upgrade kit ($450) which moves 20% more air per revolution than the stock powerdyne impeller. Combined with the race bearings and the new impeller, it's possible to see 16-18psi boost with the silent drive head unit.
The average used cost of a BD-11A is $500, and the average rebuilt cost (with race bearings + kevlar belt) is $1100. This makes it a fairly reasonably priced head unit that can be used in a lot of custom applications.
I'm rather surprised folks are not making blower brackets and using these. For relatively short money you can supercharge your car.

Re: Powerdyne superchargers
I just rebuilt my buddies powerdyne after 30k miles. It was a PITA and I would never buy a powerdyne.

Re: Powerdyne superchargers
Why did it need to be rebuilt? The internal belt broke, froze the bearing with all the shredded belt and broke the tensioner on his when the S/C froze up. There was probably a good dozen and a half of sugar packet size amounts of shredded belt powder in there. Needed to clean the case and everything else and took a lot of time.

Re: Powerdyne superchargers
That powerdyne doesnt have what I needed. And I like my 5.4:1 step up ratio alot better!

I had my vortechs apart a few times. Those kinda sucked. the Powerdyne doesn't look too bad. The model your friend has is a BD-10 (the belt tensioner gave it away). Those are older units (think early 90s). I think it's expected to throw a belt after a while.. I imagine the belt shreadings kinda sucked.

Re: Powerdyne superchargers
Joe, i'd have to bet there arent many thirdgen guys with powerdynes because they dont make a thirdgen kit. Anybody who's willing to fabricate bracketry is typically going for a lot more power than the BD11 is able to push.
FWIW in reference to your plans to use one on your car, my friends mustang was running one with 9:1, 11 psi pulleys (saw about 10 at the gauge) a ford e303 cam, edel performer (not rpm) heads and intake, it would go 6.7@99 in the 8th with both of us in it on a 75 shot and pump gas.

Re: Powerdyne superchargers
I run a Powerdyne on my Yukon and LOVE the thing !!! I am getting 12 psi with the stock 6 lb. pulley... Powerdyne was surprised, but said it does happen now and then ? Why would that be?

Car: '92 Black Camaro RS
Engine: 305 TBI
Transmission: 5-speed T5
Re: Powerdyne superchargers
I have a '92 Camaro RS with 5 speed manual, and 305 engine. It still runs good at moment and has 172000 miles on it. I am planning on pulling motor out sometime in near future when I have extra cash and doing a complete rebuild.
Some of my friends are telling me to just put a 350 in it, but for some reason (don't ask me why) I want to keep the 305 in it and build it up to keep up with some of the big dogs.
To let you all know I do not want to go all crazy with this, I want to keep it street legal and a somewhat of daily driver. But want some opinions from some of you who may know a little more on what would be best for me to do (ie. What motor would be best, etc).
I am thinking about putting twin turbo charger on it if possible but like I said before I look more into this I would like some opinions on what to do and what not to do.
But would like to really super charge it. I am probably going to get a gen I 350 and build it right for what I want.
Thanks for everything in advance.
