need help with a s/c

Hey guys, I need some help. I have a 01 GT that I put a Saleen s/c on 3 years ago. It will not make any more then 4psi now and it's leaking oil out of the s/c. My motor has 38,000 miles on it and it's fine. Should I rebuild that f*** s*** Saleen s/c? Or I was thinking of the KB 1.7L s/c. I hear they are the best out there. Dose anyone have one on this forum and how is it? How much boost can the stock motor take with the KB? I thought it's like 8 or 9psi, right?

Any help would be grate:)

Thanks, Mike
 
If you plan on keeping your car for a long time, I would suggest you find the fix and apply it. This way you can fix it the next time you have this issue.

Do you regularly have your drain line blown out at oil changes?

It could plug and cause oil to ooz/spew/chuck/puke/toss... what ever you want to call it. Have air blown down through your drain tube and RUN IT!

KB means having to remove a whole manifold application instead of a bolt on, for repairs and rebuilds....remember that!!!

No drain line to blow out DV. Unlike your Centrifugal, the Saleen uses a self contained Eaton blower.

Mike, pull the blower and check the condition of the rotors. If they're loose or have any unusual play or wear, you're probably in need of a rebuild kit....which can be purchased in the $500-$600 range. It's unusual for them to be worn out, with such little mileage (I presume) though. Those Eatons are usually good for 200K before wear gets the better of them. Something may have broke, but you won't know until you get a look at it.

What size/model blower are you running? An M90 or an M112?

I got the Saleen SERIES 2 blower 3 years ago. When it was new it peaked in second gear at 6,000rpm at 12psi. After a year it started losing boost and it's been whistling ever sins. Like it's losing air out of the s/c, but I checked all the lines and they are all good. It has 20,000 miles on it. I thought the rebuild kits were around $2,000? That's good it's only around $500. I'll pull the blower and check it out.

This is the picture of my motor.

Before you tear the blower itself apart, inspect the other areas of the system (inlet, vacuum lines, intake surface, etc,) The leaking oil is a problem the needs to be addressed, but the loss of boost pressure just may be a vacuum leak somewhere else within the system, especially if it's accompanied by a whistling noise. Like I said before, you won't really know until you get it off, but 20k isn't a lot of mileage for an Eaton and unless something has been damaged, it shouldn't need a rebuild due to wear for a long, long time yet.

Your blower is an M90/MP90 BTW and if it is in need of a rebuild, contact http://www.magnusonproducts.com/ for the specific model and parts. www.superchargersonline.com sell rebuild kits for Ford and GM M90’s as well, but you’d better check with Magnuson to make sure they’re the same.
 
As Gearbanger said check for leaks, that is most likely where your boost is going. After that, check the guage sending unit itself. As far as the oil leak, make sure it is coming from the blower before you start removing things. If the oil is not around the snout, or front seal, the leak is probably from another source. If it is leaking, front seal and bearing kits can be pruchased for less than a $20, and a complete rebuild kit for around $175.

Ahh, you one upped me :D . The prices I found at superchargersonline included the cost of them doing it for you. So if a do it yourself kit is available and he's capable, better still. :nice:

I don't want to start a *issing contest, but I like my KB. I'm getting 11psi from my "9psi" kit and haven't had any problems...yet.

Check to make sure the bolts that bolt down the blower to the manifold aren't loose. They have been known to back off and the boost pressure pushes out the gasket.

Thanks for all the posts, you are very help full. THis is the best forum I have been on and got help.

I will check it out this weekend, it's been crazy this week.

The oil is coming from the back gaskit from the s/c. Maybe they did come lose. I'll look at that this weekend. Thanks again:D

From this picture you can see the oil on the back of the s/c lip.

Yeah if it was sc oil, it would be around the front. Looks the you have a leak around your adapter plate. Tighten up the bolts and will probably be fine. You might want to look into getting a catch can to keep the oil from going from the pcv through the intake, although if you had one now you might not have found your leak.

Edit: Looks like you have some leaking around the top of the plate. You may want to unbolt the adatper plate from the lower intake, and tighten the bolts holding the plate to the blower. They are kind of countersunk allen bolts.

Sorry but where are you talking about? What is the PCV? is it the black round thing in the back of the s/c with pink foam?

I see you have the same s/c I have. How do you like it? Dose you're s/c act like a roots or not. mine only reads 3psi at 3,000rpm and slowly gose up from there. It dose not peak boost intill 6,000rpm. Dose you're do that? How much boost are you putting out? When I had it installed it peaked in second gear at 6,000rpm at 12psi. It just keeps going down. People say they do not last long at that boost level and I have to rebuiled it. I have 20,000miles on it now. How any miles are on you're s/c? And do you have this problems?

Thanks, Mike
 
Hey you're not going to believe this. I was having a idle problem too. So I bought a new TB sencer and I took it for a drive and the idle was still not right. So today I thought I would take it for a ride before it snows tomorrow. It idled fine and the car had a lot more power. I opened her up and the s/c was so loud and I looked down at the boost gauge and it was making 10psi:D It has not made 10psi for a year now. Could have the TB sencer made it not make max boost? I thought I was seeing things, so I drove around for a little bit. Every time I had my foot to the floor and at 5,000rpm to the fuel cut it made 10psi. Could have the cold temp have anything to do with it? it was 33 degrees out. But It's still leaking oil?
