Dont understand why you guys would say its ok to drive with the belt off? It doesnt change anything really as the supercharger still spins at idle and knocks even with the belt off.. definitely not going to run it anymore. I really want to try dissecting it myself because I have the tools and not sure if ill be able to have it looked at so close to Christmas.. but I'm pretty sure that task is out of my mechanical league, even with my alldatadiy.com account. :'(

If your 100% sure its the SC, get a good used one. It will save you time and money. Put up a post, there has to be at least 2 people that have upgraded to a Weistec.

I agree DO NOT RUN THE ENGINE. Belt on or off. If the vacuum spins the blower with the belt off your very likely furthering damage that's likely already there and risking even more damage. The blower needs to come off and be properly inspected. Also the intake needs to be gone through to see if anything made it past the blower. Your only good luck here is that a used blower is relatively inexpensive compared to the unbelievable rape the dealer would try to impose on you for a new one. STOP RUNNING THE DAMN MOTOR! Just some friendly advise.

If your likely to have to get a new blower (seems pretty likely) I say open that puppy up. It's not as bad as you think. Then again I'm not sure how experienced you are?

GT-ER

He even went wot with this noise and it still does it. I highly doubt driving it to a shop will be worse. I woild just drive it. You guys are also forgetting that the intercooler will stop any pieces from getting into the engine and it comes out with the sc.

Regardless, it's just what I would do.

Playing with a hand grenade with an unknown lead time in my opinion. If something is wedged into a rotor how many slaps before a chunk cracks off? 5000 seconds or 5 seconds? Why find out?

PACougar

I've had the same thing happen, with the exception something got in there while the SC was on the bench. I had the same sound as well. Take the SC off and then pull the screws out, it's easy and you can evaluate the damage fro yourself. How much time did you let it run while making that sound?

Jakez

I'm not sure how long it was running with the sound because I drove somewhere and when I started the car again it started making the sound and I quickly drove it home. It could have happened as soon as I left to go there or happened right before I parked. So anywhere from 15-30 miles or 30-45 minutes. Although I don't remember hearing it when I stopped at lights or parked and I'm sure I would have because it's pretty noticeable.

Not sure if I want to attempt taking it off myself because I don't want to mess with unbolting fuel rails and this long list of other things alldatadiy says like needing star diagnosis.. doesn't sound like an 'easy' thing to do lol. And I've already made enough stupid mistakes.

And one of witch was driving it with no air boxes and open t/b
Lessen learned
This isnt gona be a cheap fix... just an fyi
But good luck hope its not really bad

PACougar

Well hopefully you'll get lucky, I was able to lightly sand out a couple of small nicks in the rotors and the SC was fine.

Hulk

hey PAcougar, now im really going to make sure i dont make any dust or anything fall into the sc when i take it off to do the tb since you got something in there when it was on the bench lol

PACougar

It was the craziest thing ever, we literally took it off, bagged it, and then later on unbagged and bolted it on. It turned out to be a tiny piece of aluminum and we still have no idea where it came from.

GT-ER

Again, it's what I would do. I have enough experience in these things that I dare take these chances because they are really THAT minimal. But, whatever he does...he needs to pull the SC off.

GT-ER

You do not need star diagnosis and it's actually pretty easy to do but is VERY heavy ( I use my engine crane to pull it off so that I don't break my back in the process ). Two people can do it in about 1 hour easily.

Jakez

Man, I really respect your advice on here (and everyone elses, thank you all) because you make things sound so easy and know what little bs tasks can be excluded from doing something to make it a more simple job. Due to your posts in various threads I've actually attempted more than a few things myself on this car that I would never attempt and came out very happy that I accomplished it myself and got more familiar with my car. I think I'll see what tomorrow brings, whether or not my indy shop will check it out and if not I'll disassemble it myself to inspect and maybe just have the shop put it back together later.

GT-ER

If you swapped your rear air bellow yourself, you can surely remove the supercharger. Let me know if you need any help along the way.

PACougar

I agree, as long as you have the correct hand tools it's a easy job. Make sure you have a friend handy to pull it off and put it back on.

berti_00

Does the sc need to be removed to take the inlet off??

Jakez

While we're here does anyone know the size of the stock supercharger? I know the Weistec is 3.0L but I've searched and searched and searched and can't find any size info for the stock one.

PACougar

Yes, it does have to be pulled.
As best as I can tell and according to Weistec it's a 2.1L.

Jakez

Do I need to remove the fuel rail all together? I wish it was just an all unbolting job, messing with fuel lines and hoses annoys me.. I've gotten as far as removing the surge tanks and now I'm stuck wondering what to do next lol. Someone needs to do a friggin DIY.

kustom2k1

Try this site for info, you can remove the intake as one whole piece, no need to take the airboxes part

Jakez

I was looking at that earlier but when he gets to the part about hoses and fuel rails and sh*t he just skims through it like its no problem lol.

kustom2k1

Its pretty simple, drivers side has the main feed. Use a rag to catch whatever fuel runs out, and 4 bolts hold the fuel rail in place. If you start it and run into problems, you can post questions and get walked through it.

GT-ER

I've done it three times and have never disconnected my fuel rail. I just set it aside in the drivers side strut tower.

03'55AMG

This takes *****. I've always wanted to pull the s/c, never had the shnuts to try it. Random question that may help others in the future, can somebody effectively name off EVERY tool necessary for this kind of job? Ill check WIS later, but not everyone has WIS
