Powerdyne any good?

[redrider]

On the fence about powerdyne supercharger. Please help me make up my mind.

If you do a search on the Corral about the Powerdyne, you'll find less than favorable results. The problem is they are not the most durable s/c on the market, and their customer service has a horrible reputation. Do yourself a favor and look into getting a Vortech S-trim, ATI P1SC or a Novi2000.

I'm planning on S/C in te near future. I'v done some research, and I'm probably going w/ the ATI Procharger P600B or P1SC (both intercooled). ATI's w/ intercooling are cheaper too, in comparison to other similar Vortechs/Paxtons etc. Whatever you do......get one that's intercooled (more hp and it'll save you $$$ in engine problems. Looking to get one soon? Good luck.

I have a powerdyne on my 92 GT. I admit I do love it, but the vortechs are superior. The powerdyne is so quiet people will never suspect you have a blower. That's the strong point. The weak point is the internal belt can break. I believe they cleared their problem up. The old blowers used to have an internal tensioner, and it would seize up and the cut the belt in half. Mine did and I replaced it. Cost $60 and 6 hrs. of my time. A good thing is the simplicity of the blower. just a fan with a belt. No gears, no oil. If i had to do it over again, I would buy an A-trim vortech. Easily upgraded to 10#'s and sounds awesome. I personally love the blower whine. Get a VORTECH!!!!

I have the latest version....the BD-11A, It has NO problems so far(knock on wood) and has about 20K on it. I have the 9# pulley, and thought about going up to the 11, but sources say DON'T, even though they claim to hold 14# w/o breakage, but I won't chance it...I am fast enough for now.....

Vortechs are better, but pain to maintain and install(from what I have heard) and they boost their advertised number, unlike my powerdyne that only boosts 5-6(REALLLLY PIZZNIZES ME OFF) Other than that it is a great street blower, but if it is 9's you want...save $$.

There is no extra maintenance with a Vortech (over any other blower). I've had mine for 3 years, with no problems at all. I change the oil/filter every 2500 miles, and change the plugs and fuel filter once a year. I wouldn't call that a pain.

As far as installation, the only issue most have with the Vortech is tapping the oil pan. Actually, tapping the oil pan is much easier than you think. Once you've done it (or seen it done) you'll know what I mean.

[SaleenGTS]

My bad, just rumors you know...I am not sayint that I would rather have a powerdyne than a Vortech, cause it is the other way around....I just hate the fact that my damn blwer only boosts 5-6 #'s instead of the claimed 9.

On top of the problems smokedchevy mentioned, I think PD suffers or at least suffered from quality control, they just didn't have it. Before I purchased mine, I called around to some speed shops to get their input on PD superchargers. The ones I spoke to claimed the BD-11A model, like mine, are not breaking at the alarming rate the earlier models were. They haven't had too many customer complaints on the new models. This obviously isn't a scientific study, just my own research.

I do worry every time I step on the throttle whether or not the internal belt or bearing will give out. Yet they can make decent power though, just look at my sig. I have put about 2500miles on mine with 10 1/4 mile passes without a hiccup. Only time will tell if it will last.

I would still recommend Vortech or ATI unless you can't afford them. I got such a great deal on mine, brand new, I couldn't pass it up. I really wanted the new P-1SC but just couldn't fit it in my budget. Good luck.

1995 MGTS, your blower should be fine. The new model you have has had the internal tensioner removed and the belt shortened. As a result of no tensioner, the insides of the new blowers have been lightened. I just unscrewed my tensioner, chucked it in the trash, and bought a shorter belt. Works great. Also, the only reason the belts break are due to the sudden strain of clutch dumping drops. The impeller RPM goes from 60,000RPM to 33,000 Rpm in no seconds flat.

[SaleenGTS]

1995MGTS-What are you boosting at on your guage??

I am boosting at 5 with a 9# pulley, it kinda pisses me off...

smokedchevy, you seem to know your $hit when it comes to the Powerdyne. I'm coming to you from now on with my PD questions :} Here's a question for you, I have heard ASP makes pullies (crank I believe) that can increase the boost on the PD without putting more stress on the blower. Would you happen to know anything about this? Thanx

SaleenGTS, I see about 4psi on my boost gauge. I wouldn't worry too much about your boost pressure. Isn't boost a measure of back pressure? You seem to have a good combo so though you don't see 9psi, you are still making good power. If you are making 390+rwhp untuned, you have alot left on the table. With 9psi, you are most likely making great torque numbers. I still have some hp in my combo but my torque seems to be maxed.

I haven't heard a lot about the pulleys. But any time the blower makes more boost by changing pulleys, the impeller is going to spin faster. I'm not sure how fast the impeller can spin before frying the bearings inside. I believe powerdyne makes an 11# update kit for their blowers. I don't think the belt driven PD was intended for serious race action, and modifying the impeller speed is going to start hurting stuff. You couldn't be doing that bad with 391 rear wheel horses!

[Blwn88cpe]

1995MGTS, yes ASP makes a one piece 7" crank pulley that when combined with the 9# blower pulley is supposed to make around 11psi. Houston Motorsports did an install article on this awhile back. They stated that it does not overspin the blower(its right at the max recommended rpm). I have this setup on my car and so far I've had no problems, knock on wood. My best so far is a 12.2@120 on 17" nitto dr's. I purchased my pd 4 years and 6000 miles ago, before I had the info that is available online. If I had to do it all over again I would have gone with a Vortech S-trim. I'm seriously considering a turbo kit in the near future.

[1995MGTS]

Thanks for the info guys. I am probably going to go with a power pipe, larger injectors, and maf. Trying to get the max power out of 6psi. I am also planning on being a guinea pig by replacing my belt driven PD with the new gear driven PD if it ever comes out! I figure it will be easier and cheaper than going with a Vortech for more power since it should fit right in with my current brackets. No modifications required :}

That is entirely UNTRUE!
My car is an AOD, and broke the internal belt randomly at various speeds and loads. No less than 6 times!
