Powerdyne BD11a -- who actually owns one & has some dyno numbers?
Looking for some actual HP & TQ numbers and/or actual track times for the Powerdyne BD11a. I've heard all the stories about belts breaking at higher boost levels, get a Vortech instead, yadayada, etc... What I'm looking for are some actual owners to chime in please.
Even if you don't have numbers but you own a BD11a, I'd like to hear your experience.
Thanks!!!

don't even bother researching them. just go here and read the reviews. i don't care what kind of deal you get on it, get a procharger or VORTECH.

RE: Powerdyne BD11a -- who actually owns one & has some dyno numbers?
I agree with nanaki all the way, but before you make a desicion read this. Here is what I said in another thread about Pdynes.
One really nice thing about Pdynes are their "Hyperdyne" curved impellers. They actually scoop air so their can achieve higher boost levels at lower RPM's than other Centrifugal's. Once again their drawback is that anything past 9psi will pretty much blow a one all to hell. Pdyne has come out with a gear driven version but I dont know how thats working out. If youll want higher boost numbers down the road dont bother with Pdyne, youll just end up selling it for a quality Vortech unit. Pdyne is a good entry level street blower for someone on a budget. A Vortech is an extremely high quality unit that will give you years of trouble free use. Youll also have extra room to grow in. It all depends on what you want.
You would be fine at 9psi but, I wouldnt go any higher than that. Your engine couldnt take anymore boost and the entry level Powerdyne isnt made to put out anymore. This is gonna be very strange for me to say and some people are probably gonna have contradictions but, you would more than likely be very satisfied with a Powerdyne. I just realized I have been bashing Pdyne on hearsay which isnt like me so I researched the product myself to see what all the smack talk was about. I found that most of the negatives against the supercharger were user mistakes. Lots of people will tell you the internal belt drives are crap and snap. This is true if you want to go over 9psi of boost but, Pdynes entry level S/C's arent designed to go over that ammount. Also most people dont realize that Powerdyne has switched to a new Kevlar belt which is much much stronger than the previous designs. Another common problem are the ceramic bearings. Where it is true that these bearings are not as strong as normal bearings, they have amazing heat deflecting abilities. Many people run into problems with these bearings because they overspin the S/C by running to much boost. Even if you did break a belt or fry a bearing, Powerdynes are the easiest to rebuild of any S/C and also run the coolest. Ive just talked to several guys running 9psi Powerdynes. One guy has had his on a 93 Cobra running 9psi for 5 years now with absolutely no problems. He also takes very good care of his car. If you are looking for a nice entry level street blower on a budget then a Powerdyne would be a nice choice.

how much is a pdyne kit? i didn't think it was an entry level blower when i last priced them. they're right up there with vortech almost. may as well spend the extra couple bucks. unless they've dropped since the last time i looked at them.

I know Jegs had a big sale. You could pick up a kit for an 87-95 5.0 for $1600.

Do you own one or use one? I get conflicting stories but, theres about 30 guys on Stangnet that own them and swear by them. The one I talked to has had his on for 5 years, he started at 6psi and after 2 years upped it to 9psi and hasnt had a problem one. He also takes very good care of his car both cosmetic and mechanical wise. The two guys Ive seen on here that own them also havnt had any problems with them. People used to think Prochargers were crap until they realized they fixed their problems. Now all kinds of people happily pack ATI's. I think if Powerdyne were as bad as everyone says they are, they couldnt stay in business. The more I learn about this kind of stuff the more I realize, dont knock it til' ya try it. They are designed to do differnt things than most people on this forum want. Than again they could be total crap.

i'm going by the countless reviews that were posted in that link. it doesn't have a very good user rating. people either gave it a 5 out of 5, or 1 out of 5. there were more 1s than 5s though. looks like it's hit or miss with powerdyne. just google it and you'll find lots of not-so-great reviews on it. i'd rather just spend the extra few bucks and get a procharger or vortech.
