what are some of the issues people have had with these SC's?

 

there is a rubber belt inside of them that always break....It's an issue that takes quite of bit of labor to overcome..

 

i think i remember someone saying that powerdyne has an upgraded belt now that helps alot but still isnt a total fix for that problem.

 

Yes, a kevlar belt is available. Other problems are with cooling which was addressed with a third fan, and drive belt slippage at boost which can be reduced by using a manual belt tensioner.

 

actually there is a company out there that does a complete "race rebuild" for Powerdyne's to get as much as 15psi out of them...

A 928 Motorsports, LLC Exclusive!

BACKGROUND: The standard bearings used in most Powerdyne Rebuilds have these limitations:
a normal operating range of 26,000 RPM and a peak ceiling of 38,000 rpm
a lubrication within the bearings that is rated to 280 deg F
OUR RACING REBUILD: We worked with SKF Engineers to solve these limitations, and now have
a normal operating range of 40,000 rpm and a peak ceiling of 60,000 rpm
a lubrication in the bearings that is rated to 302 deg F
in addition, we add:
venting and shimming to keep your bearings cool
a Kevlar GT-series belt
new hardened steel SKF bearings for the drive pulley
EXPENSIVE? Consider this: the Racing Rebuild will last longer between rebuilds - and costs about the same as 2 regular rebuilds.

HORSEPOWER A-PLENTY: Now you can use the pulley you want to, and get the boost you always dreamed of from your Powerdyne without over-spooling it and blowing the bearings out. It'll SAVE YOU MONEY the first time you do not have to remove it from your car and send it in to be rebuilt!

THE WARRANTY: Sorry, no warranty provided on Racing applications. We have more experience than anyone else rebuilding Powerdyne Superchargers, and I can assure you it will leave our shop ready to race.... the rest is up to you!

$700 is a good price. I got a full kit for $600 that I had to rebuild. Sold it to a V6 guy in order to go turbo. Watch the belts. Youll be fine at 5psi. Get the better tensioner and proper fuel (used svo 30lb injectors work well). Just make sure its a decent quality piece otherwise, and you may want to consider a rebuild regardless. You can probably have everything installed tuned and ready for under $1800. Factor in $500 for tune if your not a DIY tuner guy.

 

If you don't buy this PM me so I can.

 

**** man for 700 bck i would say do it. But you have to make sure the thing works. And also your gonna need other stuff. Make sure you want to do this.

 

lol this was dug up from the grave

 

ysi dude

 

for 700 dollars you can not go wrong. I vote yes

 

as long as it works. im sure you can make a cheap fmic work and up the boost

 

I'm pretty sure he's already made his decision since he asked this almost 7 months ago...

 

Haha yup.

I just saved up a little more and installed; gears, cam, and nitrous instead.

 

Good choice, better bang for the buck for sure.

The upgrade mentioned by 928 are nice, but it does not overcome a poorly designed head unit to start with.

A friend had one, broke the 'brand new from Powerdyne' belt on his first 1-2 powershift.
Sent it to 928, got it back, new bearings, new support, few other mods, and their latest, greatest belt, and it made it through the 1-2 shift, but killed itself on the following 2-3 shift.
Never got so much as a 1/4 mile out of the blower before it was promptly replaced with a HP-76 turbo setup. (Boost is addictive...)
