supercharger problems?????
Re: supercharger problems?????
sounds good, boost gauge is on the way. im going to get in to the intake tomrrow to see if it is blowing air, where is the MAF located? i will check out my S/C directions to see thanks for all the help

As the others said, you may be able to send it back for warranty repair if the internal belt's broken. Let's not jump to conclusions though, I would be surprised if it's broken already. Are you sure the discharge tube of the blower is connected to the up pipe securely? That is a very poor fitment and if someone carelessly hooked it up you could leak major, major amounts of boost at that point. This stuff is not hard to check out yourself at all, all you need is a screwdriver. Check the simple stuff first ...hell, as said, why not just take off the up pipe or TB elbow and just see if it's blowing air through it. Also, you should hear a faint whine as you decelerate from say 1,800 to 1,200 rpm ...just rev the motor with the throttle body lever and listen for the mild impellor whine as the rpm dies from 1,800 to 1,200 and then to idle. It's a quiet blower but it should be clearly audible with the hood up and listening for it. Your installer may have hooked the MAF up backwards too .....not so hard to do. Your car should trap 111-113 MPH with that setup. If you rebuild the blower, there are better options like a stronger Kevlar internal belt and beefier bearings.....I would let a professional do that if necessary, or let PD do it if it's under warranty of course. I'm hoping and guessing that you're going to find a simpler problem though, it's hard to tell what might be wrong at this stage. The external belt really needs to be pretty snug ....are you sure it's really tight enough? You should have about 1/2 inch of deflection when you push on the middle of the belt, or grab it with your thumb and index finger in the middle and twist it, it shouldn't want to turn any more than 1/4 turn without really heavy effort. If the external belt is slipping you should find rubber shavings on the cooling fins of the supercharger unit ...shine a bright flashlight on it and look. Keep us posted, I'm sure we can figure something out.
Edit: I just noticed earlier in this thread you said you're using stock plugs. Regardless of this problem that could be a problem in and of itself too. Stock gap is .060 I believe ...which is too much for a blower. Also, stock plugs are platinum tipped. Platinum can melt and cause detonation. I would strongly suggest Autolite 104's gapped at .035 ....don't worry about it, they're cheap as hell and work great. They are one heat range cooler than stock and are a copper plug ....much, much better for your application. That big .060 gap could be allowing the spark to get blown out. Do you have a multi-spark ignition hooked up? (not a big deal but helpful) Also, do you have a timing retard hooked up or a custom program? Very important, you don't want to use full ignition timing with a supercharger.....especially on these 10.5:1 engines.

Re: supercharger problems?????
You probably should have learned what the MAF (Mass Air Flow sensor) was, as well as many other automotive terms before investing in a supercharger.
This thread has been making me chuckle. Let me know if you want to bail out and let it go for cheap, maybe I can get it working on mine!

Re: supercharger problems?????
Sorry I shouldn't have been a schmuck.. I'm just jealous. Reading back on your original post, have you tried tossing on wider wheels/tires to control that thing on the road? You're looking for more power, but already notice an unreliable grip to the road. Even my basically stock SS can't stay put off the line and I thought my 17x11 was an upgrade
. Sorry.. I got off topic. Carry on, I'm still interested in why you're not getting boost..
MAF should be located just before the throttle body, depending on the modifications made for the supercharger install. If you look under the hood, and still have the stock MAF sensor, you will see it connected to your intake duct with red pointing arrows toward your intake manifold. Should be easy to spot.

Re: supercharger problems?????
HELP, i pulled my intake elbow off and started the car, how much air should i be getting??? i was def getting air coming out, the car was starting to die, so i couldnt do as much as i wanted but it seemed air was coming out, let me know guys
thanks ed
thanks ed

Did you disconnect the MAF? If not, it's reporting incorrect airflow.

Re: supercharger problems?????
You need to disconnect the MAF sensor before you start the car. In the stock car, it sits right next to the elbow, it is usually gray/silver and has a black box connected to it with an electrical connector that connects to it. I am not sure on the powerdyne setup, but the ATI setup makes you move the MAF and connect it right before the air filter.
The car will run without the supercharger hooked up, it will suck the air it needs in. (How do you think it got air before the supercharger was on there?) .. Disconnect the MAF, and restart it, how much air is coming out of the elbow ?? It should be a lot, like a lower powered leaf blower.

Re: supercharger problems?????
With the elbow off you have to unplug the MAF and run like speed density or else you're going to run insanely rich, it's likely you've flooded it. You see, the MAF measures how much air is passing through it and the computer adds the appropriate dose of fuel; but when you have the elbow disconnected that air isn't going through the engine, instead the engine is getting a tiny bit of air from the IAC motor. What you end up with is a gross misrepresentation of how much air is really going into the engine (the MAF is measuring a lot more than the engine's actually getting ....ESPECIALLY with the supercharger blowing air right through it). So the computer adds WAY more fuel than necessary and you've flooded out. Next time you start it hold the throttle wide open as you crank it to help clear the flooding. The MAF should be just downstream of the filter as said, there is a simple connector on it that you can pop off with a flathead screwdriver, pop it off before you start it again. Since you said air's coming out of it, that pretty much answers the question, if the internal belt was broken I doubt the impellor would turn at all ....so it should be ok. The thought of a broken internal belt on a brand new blower is kind of ridiculous anyway, but possible since we're talking about a Powerdyne I guess 
Make sure the MAF is on correctly while you're looking at it, as said there should be arrows pointing downstream (toward ductwork rather than filter).
