Powerdyne Rant

[98GREENGLOW]

I just gotta say some stuff and I didnt no were to post it so here goes..... Lots of times when Im reading on other post I see people who dont even have a powerdyne saying that it sucks. I even read today that there are only two real forced induction alternatives.... The ATI kit and Turbo. They said that the powerdyne wasnt worth mentioning. Talk like that just pisses me off. They are saying it's not worth mentioning? This is how I see it. The kit has proven on two dyno's that I know of to produce 260 rwhp at 8 psi. That's roughly 100 rwhp over stock! Yet it's not worth mentioning? The kit has also proved that you will take anywere from 1 second to a second and a half of your et with 6-9 lbs of boost. It's still not worth mentioning?You can look on the time slips page and see three examples of people with the powerdyne all ATLEASTE running the times (or better ) than a stock LT1. Worth mentioning yet? The kit has proven reliability that expands over 5 years! The only problem with the powerdyne is the pully. It dose slip. However I had mine grooved and now have no problem maintaining 9 pounds of boost. I just get so mad when this is the only forced induction kit for are car that has been massed produced and has a proven performance and reliability record. I think most of the problem is that the powerdyne kit has been out for a while and everyone just dismisses it as old news and says it sucks. Heres the real deal. Go to superchargers online.com and read some stuff. You'll find out that the powerdyne and ATI superchargers are neck in neck when it comes to rteliability. One month more people are complaining about the powerdyne, the next month more about the ATI. Both of there scores are usually between a 2.5-3.0 out of 5. The vortech S-trim usualy hangs in the high 3's-low 4's. My point is that the ATI charger as a system has no better of a reputation than the powerdyne. But people who dont even research it are saying that the powerdyne sucks? Did you know that there are people running 13 lbs of boost off the same powerdyne us v6 ers use? All you do is change your pully and get it grooved. It's that simple. Of course you'd have to build up your internals but you can read " SWIFTS GUIDE " if you want to learn more about that. He he. I find 9lbs of boost enough for me right now and think the system is defiently worth mentioning. For two grand you can get a used powerdyne, spend 50 bucks to have the pully grooved and be ridind around with 9 psi all the time. You could pend another 500-1000 to have it custom intercooled. All that would cost you less than 3 grand. My machanic is gonna intercool mine for 500 total. I wont lie and say I'd rather spend 3 grand on a used intercooled powerdyne than somthing from force fed productions that's new for only 3,500, But I would rather spend the money on a used powerdyne that has just as good a score as the ATI and save my self two grand. Now this is not a post to say mine is better than yours or any childish crap like that. But until the kit takes two full seconds off someones quarter and dosent break and has been reliable for 5 years to members of this board I will still stand by the fact that the powerdyne is defiently worth mentioning.

I can see where you're coming from, but I think if you're paying soo much money fore a Powerdyne, then it should be able to do 9 PSI out of the box all day long without any problems, like it says. That's the only issue I have with the Powerdyne, and it's a fairly big issue at that, an issue that too 5 YEARS to figure out how to permanatly fix...

Well I have no complains about my PD. I've been pleased with it and I've had it almost as long as I've had my car, which is a little over 5 years. No problem so far.

As far as reliability goes. PD was plagued by bugs in the beginning when the company was new. First the bearing wouldn't hold the heat from high rpm due to poor lubrication. Then the belts would break or over run on its cog tooth. Then the small roller use as a tensioner goes out then the whole bearings and belt and gears goes along with it and causes it to seize. Then they introduce the polish unit, that had problems on its blower halves.

Now they use high quality bearings that exceeds rpm range with better lubrication, and reinforce kevlar belt for long life. They also removed that small roller that served as a tensioner to avoid damage. The polish unit has been impoved. The reliability has improved tremendously, comparable to that of Vortech and ATI.

The only draw back to PD is that alot of performance minded people gets hooked on boost. PD is only known for 9 psi. and up to 12 psi but anything higher than 9 psi compromises the reliability of the SC. That's where people are looking at ATI, Vortech and turbos go above 9 psi.

For me PD, Heads, Cam, and replacing my water injection with N2O or maybe both would pretty much satisfy me. I believe you could break into the 11 sec. with that, with no bugs ofcourse.

Well Powerdyne is becoming more popular in major automotive industries. They prefer it because it is quiet and more bang than the root blower. My dad has a Mercedes 320 and he wants to SC it. He showed me a brochure on the Supercharging option to increase HP. Believe or not, Mercedes is using Powerdyne BD-11A as their blower of choice. My sister's BMW Z3 roadster also has Powerdyne as a choice for blowers.

Powerdyne is worth mentioning because it advertises itself correctly as to what it does. Thank Goodness that there are about 4 articles on this from different magazine that say what it has done for the V6 F-body.

As far as slippage goes, thanks to you, that might not be an issue anymore. [img]graemlins/thumbsup.gif[/img]

All new products will have "bugs". Some people in here that think they will shell out the bucks for a different blower or turbo kit are in for a rude awakening..so what if the belt slips? Ever think that it might just save your motor? As for 9psi on a supercharger, you ain't gonna see much of a difference in ET because superchargers create an immense amount of heat. Getting this amount of boost is not that difficult, even with the Powerdyne. I've seen 11 psi on it. But anyway..... I think that a lot of the people in here are putting the Powerdyne blower down because of Greenglow's experience, when the fact of the matter is, that things like that can and WILL happen to ANYONE who takes on the task of modifying their car with a blower. He was just man enough to ask questions and talk about his experiences. Will some of you do the same? Probably not, because you won't want to be put down by others who have not taken the same direction. So, those of you who talk negatively, put up or shut up. Another words, MODIFY or keep your mouth shut. I as well as others are getting tired of seeing your ridiculous sigs that say "11 second bound" when in fact you have very little or NO modifications done to your car! And anyone who doubts the Powerdyne, you can go to my site and look at the article from GM High Tech Performance.

I have to agree with that. When I first got mine, it spent almost 2 months in the Vector Perf. shop due to all these bugs. Eventhough James have installed them numerous times on other V6-Fbodies. Every car seems to be unique on its own ways and had it own unique problems.

OFF TOPIC: I just want to say Shirl that you have been a great inspiration to me. And I do want to thank you for the help you have given me in the past.

Yea sorry... I do need to start writing in paragraphs. As far as coming out of the box and running 9 psi all day long... I agree. But when you can seriously pick one up for so cheap, putting a groove on the pully should be no problem. I saw a guy on this board sell a incomplete kit for $900. You can get a complete one for only 2 grand. Why did it take so long to figure out the slippidge? I heard so many people talking about using tape and differrent belts and putting a diamond knurl finish on there pully that I just said screw it and had my mechanic put a groove in it. It worked so good that I now have to let my belt have a inch of play so I wont get too much boost. Am I seriously the only one on this board to do this in the past 5 years? Mighty Thor I agree with you completely on he evelution of the powerdyne. However from what I have been reading on the powerdyne tech board.... 9 psi is not the limit of reliability in many peoples opinion on that board. Most people say that 11 psi is when your asking for trouble. Weather it's 9 or 11 really dosent matter though, because I think it would be asking for trouble to run more than 9 psi on our stock internals no matter what system your using. Shirl I also think that your right about people thinking negatively about it due to my experience. But what they are not seeing is that I AM RUNNING 9 PSI ON IT. Sure I only dropped one second with it so far, but did any of them notice that I dropped that full second while only gaining 3 mph? That should show that Im getting the power but having problems some were. There has never been one problem with my powerdyne. Only my car. I just wrote this to let everyone know that the powerdyne is defiently worth mentioning and for the money (used) is the best mod I think you can do. Oh BTW I may have only dropped a second so far but Im learning as I go. I recently realized that my spark plugs have been gapped at .60 since the day the powerdyne was installed. Thanks to you guys I gapped them correctly at .35 and My top end is much better now. I also just figuered out my jet scu 2000, and my gears now change at 5900 vrs the sluggish 5200 they used to change at till yesterday. If I pulled a 15.1 a few weeks ago then I know that my times will be MUCH better this weekend due to the higher rpm shifting and spark plugs. Enough about that, I dont want to hijack my own thread. Shirl you have also been a great inspiration to me as well. You would think that the person in the number three spot who just happened to run a LS1 time of 13.9 would prove that the powerdyne is more than worth mentioing.

Hey I wrote that last one in pargraph form. I dont know what happened.

I think they mean to space your post out a little. Don't feel bad, I have a tendency of doing the same thing. Like that last post, try to have 3 or 4 paragraphs instead of just one big one. It just makes the post hard to read. ;)

Also, Green, I've been tring to follow your post with the powerdyne system. Great info. [img]graemlins/thumbsup.gif[/img] Also, have you sent the idea of the grooved pully to the makers of the powerdyne system? That way they can have the pwerdyne system ready to produce 9psi right out of the box. Would be cool. :D

But, thanks to your posts about the Powerdyne system, I'm probably going to get one next spring or summer. I'm also, probably going to intercool it. Just wanting to say thanks for making me a believer again about the powerdyne system. I was going to get one about a year ago, but heard all about the belt slippage and then decided to wait until a new system came out. So I've once again, thanks to your posts and your idea of the grooved pulley, decided to go with the powerdyne system. ;)

I think he knows what they mean.. He apparently spaced it the right way, but it came out different after he posted it.

Your exactly right camaro slp. Im happy I showed one person the light. Why spend 5 grand for 9 psi when you can spend 2 grand on a system that has been proven to perform? I think Ive had more bad luck getting my car to run right with the powerdyne than anyone alse I know and Ive still managed a full second drop so far.

Wait..... you have to let your belt slip in order to keep your boost at 9lbs??? That doesn't sound like a fix to me.

Maybe I read that wrong, but that's the way it sounds.

[98GREENGLOW]

No what Im saying is that if I actualy tighten the belt to the half inch level that it's suppossed to be at then I sometimes get a little more than 9 psi. To me that is asking for trouble and Im scared she may blow up due to too much boost on the stock internals. Si I now keep my belt loose. Trust me it STILL dosent slip. I just get 7-8 pounds of boost instead of a possible dangerous level. I think it's actualy better to be able to do this. When you really crank down on the belt to maintain boost you put a lot of stress on all your accessories. Since the day I grooved the pully I have had NO SLIPPIDGE. IF I want it to run 5-6 psi I let my belt be atleast a inch loose. It will stay at those boost levels till I change it. Same thing with 7 8 or 9 psi. It's all up to me now, vrs before when I had to tighten the hell out of it and just hope for 6 psi to last a few days.

My point is that the amount of boost you want shouldn't be maintained by loosening and tightening your belt. The belt should be tight at all times and the boost should be consistent. The boost should only change when you adjust pulley sizes or make the motor breath better.

See what I'm saying? If you are loosening your belt and your boost levels are changing then there IS slippage somewhere.

No actually I disagree with you. I beleave that when this sysytem was designed they knew there would be slippidge and rated it that way. Example... The 6 pound blower is actualy capable of making 10 pounds of boost if there is 0 slippidge. Vector knew there would be slippidge and just rated our pully at 6 pounds to not false advertise there boost numbers. However, since I have completely eliminated my slippidge problem I can maintain that full 10 pounds if I wanted to. That would be great if the engine could handle it, but I dont want to be riding around on borrowed time. The instructions say to tighten the bely to a half inch play and you will have 6 pounds of boost. If I tighten mine to a half inch I will maintain 8 -9 pounds of boost. Why... Because there is no slippidge. So I kind of see your point aboutloosening the belt, but if my belt has more than a inch of play and I still see 6-7 psi then thats defiently a GOOD thing. There is some slippidge there but only because I chose it to be there. And that 6-7 psi will last till I want more or less boost. I actually thnk it's a blessing. Of course any one who loosens there belt on any charger system is gonna have slippidge, But with there loose belt will they still be seeing the boost numbers that were advertised? I do.
