Does the car sound like it has an exhaust restriction? Rattling underneath about midway down the car?

The pins of the coupler overlap. The SC will still produce full boost without a coupler, so like the other Bill said, it'* time to move on.

I'd like to see the poster spray carb cleaner on each vacuum line and fitting at idle to search for a vacuum leak, then do the boost control solenoid bypass trick to verify it'* operation. Only for troubleshooting though.
No rattling in the exhaust, I do not think the cat is clogged, as it runs too good. I have shaken it when its up on the hoist and no rattling, so I know it hasn't fallen apart. My car does have a exahsut leak too, somewhere on the rear manifold, guesing its cracked or have a bad bolt.

I pulled the belt of this morning and spun the supercharger by hand, it spun freely with no noise or effort, spins as easy as the tensioner pully, I would think with ti turning 2 supercharger screws, that it would have a little resistance, but it has none. I also noticed that the nose housing bolts have been remover before, because the paint is chipped off them from using a socket, same with the bolts that hold it to the manifold. woudl it be possible that someone removed the nose and cut the pins off so it would not work?

I am real hesitant in pulling the supercharger off because I need the car running, because we drive it every day and have on other good running cars now.

I did the vaccum leak check, sprayed every vaccum line fitting good, even around the injectors and intake and no change in engine idle, I used a lot of carb cleaner and nothing.

anything else to check?

I think you answered the problem.

Rear exhaust manifold leak. You are probably getting massive amounts of knock retardation and your timing is down around "half dead wet turtle" therefore you can't get past 0 pressure.

I'd wait for a WillWren response..pretty sure that'* enough to do it though.

The SC pulley should have a little resistance. Can you at least pull the intake tube off, use snap ring pliers to pull out the retaining ring on the MAF screen and the screen, hold the throttle open and use a flashlight to see if there are rotors in there.

I am going to pull the supercharger off tonight and check it over, make sure its in working order, the gaskets are cheap enough.

Ya I have a exhasut leak, the one far rear manifold bold towards the passenger side snapped off, So I need to drill it out and put a new gasket in.

How had is it to replace that gasket and could that affect my supercharger boost?

I can understand an exhaust leak causing false KR, but I still think he would have more than 0 psi of boost on the gauge.

I suppose its possible but I had a GAPING exhaust leak if you recall, enough to see thru the manifold and it was NOT a cause for ANY of my KR.

mine was so loud you could hear it inside the car.

an example I've learned with my car...even with KR i still maintain full boost or dang near close to it. Whether my KR is real or not its still there and it was NOT caused by an exhaust problem. If you recall I replaced my front manifold and pulled the rear but it was fine, no cracks and not very restrictive on the welds. My car problems have little to do with the thread just throwing it out there.

I will get some pictures to show what I was talking about in my orginal reply to this thread.

thats the strangest picture i've seen in a long time.

I think your engine ate your rotors lol...or someone removed them....wow.

92-93 SC'* are easy to find for under 100.

for example:

ebay auction with a $100 buy it now <---not sure I'd trust that one though since its been ported..god knows what he did to it.

make SURE you get the GEN 2 (92-93 only) the 94-95 were DIFFERENT. the little lines on the spercharger on yours go all the way to the bottom, the 94-95 stop at the top...

Hans..thank you for the smart A** pm on something you know nearly nothing about. Don't EVEN get me started about 95% of your posts lately and the cleanup that has to be done after every one of them.

That is extremely odd, we have had one person remove the rotors from that plate. To remove the rotors from the plate between the charger casing and nosedrive takes specialized tools. So specialized that no one on this club or any other place besides American Supercharger, Magnuson and Eaton have the tools.

As for the link that Hans just posted, you do not want it. Someone has taken it apart and "PORTED" it supposedly. It'* more than questionable to say the least. Please hang in until we can advise you on the reputable vendors and sellers we know from experience. There are many out there that will take your money and give you nothing but garbage.

it was a joke

there is this auction but I would not trust it either..it would be good for a core if you were going to put a new coupler on it.

Like billboost mentioned, dont trust most ebay superchargers out there... furthermore you may want to start a thread in wanted for either a complete SC or just the rotors if you are compfortable installing them.

eitherway not having an operational supercharger is likely harming your fuel economy and confusing the hell out of your car. however it is hard to say since I've never heard of anyone running a series 1 without the rotors.

Which leads me to my next question..what kind of gas miliage were you getting without the rotors installed?
