I filled it up to the lower end of the hole, where the threads start. It was around 200ml of oil

Thank you Rob :) This morning I bought a nice bottle of gear oil and filled up my supercharger gear house. I then refitted everything to the car and once it was ready it took quite a while before I dared to turn the ignition key. I'm officially boosted again! :D The noise is as good as gone. If you open the bonnet and really concentrate you can hear a silent whistling sound when revving the engine, but it might be because that noise problem has haunted me for a few months now and that's what I expect to hear :)

Thanks mateys :) The good news is I believe I've fixed the offset problem. Now I can easily spin the pulley by hand without hearing any strange noises, finally! There's only one thing left to do before I can refit my blower. When I emptied it some of the oil was spilled. I thought I might as well replace it with new oil, but what kind of oil is it? I went to my local Mercedes dealer and told them I need oil for an SLK 230 supercharger. They quoted me £35 per litre which was just silly. I'm sure the same oil can be bought a lot cheaper when it isn't called Mercedes supercharger oil :P What kind of oil is it?

Those were my old rear lights. I got the wrong model when I ordered new ones from the states. Fortunately, though, the previous owner of your car bought them so I didn't have to return them :) Since then they have been slightly modified due to the fact that they initially messed a lot with the light bulb warning lights.

Hello again, my friends. Once again I must thank you for all your opinions and support, you English people are really helpful in every way :) Since my last post in this thread I've been driving around like this: I've been trying to get a refund from the seller (Markus at Waffenschmiede.at) but as I suspected he doesn't care that he sold me a faulty charger. He blamed Prolex Dave and cried about not having enough funds to buy the supercharger back. I didn't think he was going to help me, but at least I had to give it a try. However, today I finally decided to do something about my supercharger. Almost every day I've been tempted to fix it, but I have been super busy lately. This is what's causing my high pitched supercharger whistling: The supercharger axle isn't properly aligned with the pulley bearing. It's almost 1mm off. I had a few ideas how to solve this problem, but I wasn't sure they were feasible(?) before I examined the charger more closely. The first thing I had to do was to measure exacly how much out off centre the bearing was, as that would be the easiest part to move. I dug up my old 'something'-ometer, which is the tool to use in these situations. It can be used to measure the exact distance between the center of whatever it's attached to (eg. a supercharger axle) and something that surrounds it. In this case the surface where the pulley bearing is supposed to be. The only problem was how to attach this meter. I went for aluminium stick, a kind of copolymer which basically turns into rock :P I made my little clay creation and went for dinner. This is what it now looks like. Does it work? Oh yes! :) Attached to the supercharger axle 'something'-ometer in place Then I just had to spin the axle and take notes After that I opened the front of the supercharger and discovered that the problem might be easier to solve than I first thought. I was afraid that the front bit that I removed would have a bearing for the axle, but it turned out there was only a sealing. That means the front cover can be moved sligtly and the pulley bearing would be properly aligned along with it. The two 8mm pins are the only things that decides exacly where the cover is supposed to be. If I redrill the guide holes in the cover I might fix the whole problem. However, as it would need a pretty precise job I won't do it myself. Tomorrow I will hand it over to a professional along with my measurements and I really hope I will finally be able to supercharge my car again :) Cheers everybody! I'll let you know how it turns out.

Hello mates, I've just had a few mechanical engineers examine my supercharger and the problem is found. Unfortunately it can't be solved... It turns out the problem is quite simple. The center of the supercharger axle isn't properly aligned with the center of the pulley and its bearing. The way they figured that out was really clever, but it I'm extremely disappointed now. This means it's a fabrication fault and the supercharger will never be able to run silently. On top of that, the seller (Markus Reinisch) stopped answering my e-mails quite a while ago, when I sent him the video comparison between the borrowed supercharger and mine. I won't give up, though, I never do that. Tomorrow I will return my borrowed charger and my boosted days are over for now. On sunday I'm going to Egypt for a week, after that it's time to give Markus a call. Thank you very much for all your suggestions and help, guys. Cheers Best regards Patrik Lindblom

Thanks, mate :) That is correct, my pulley is a lot harder to move than the one on the borrowed supercharger. However, as soon as I just loosened the screws a bit the pulley became smooth and quiet. I've already removed it as well. The next thing I will do is using a separate electric motor to spin the splined superhcarger axle at 1000 rpm. If it's quiet the pulley is the problem, I really hope so. Also, I could easily turn the axle by hand. I suppose I wouldn’t be able to do that if it’s as hard to move as the pulley was.

Hi Rob, I actually did remove the outlets and examined the lobes. These are the pictures I took: This is my supercharger. As you can see there are a some scratch marks on the lobes, but in the pictures I took when I first got the supercharger there are no marks. That would suggest that my supercharger hasn't been run before I bought it. Also, please have a look at the next photo. This is the borrowed supercharger, which runs perfectly fine and is quiet. As you can see there are even more scratch marks. My theory is that the lobes are simply to be worn in a little bit. I'm pretty sure the grinding/whistling noise is caused by the supercharger pulley, as it seemed to disappear when I loosened the screws. I will show you in a video tomorrow :) Hello mate, My own supercharger is certainly quite old, but I haven't found anything that would suggest it's been run before I bought it. The borrowed one is old as well, but it's been used for maybe a thousand miles.

I was recently given one of the IS200 watches (no. 870, series D), complete with leather box and instructions manual. I might be able to scan the instructions for you, mate. I've seen a series E watch as well. Does this mean there are 5000 of these?

Here you go, Rob. Idle and max rpm of the supercharger :) Please wait a few seconds for Video to Load!

Mine did that as well. I thought it sounded great until I let my girlfriend rev my car with the bonnet open, then I realized it was actually a sqeek when the throttle was released. I tightened my belt as hard as I could and the sound disappeared :)

My car does the same thing sometimes and I’m pretty sure it’s caused by the slipping belt. I think it only happens when the rpm is low and the bypass valve is completely shut. I tried closing the bypass valve by hand, in idle, and the belt is obviously slipping a bit before regaining grip. Please wait a few seconds for Video to Load! Yesterday I picked up a 790 belt but I wasn't able to fit it. I will get an 800 belt tomorrow and then I'll use some anti belt slip (no idea what it's called in English) on the pulley. My current belt is 803 and the tensioner pulley is all the way to the right.

Never mind, mate :) I'm fairly certain the bearings are perfectly fine. Thanks a bunch anyway. I actually measured the supercharger max revs the last time, but I don't remember how much it was. I will measure it again and give you all the details about the meter tomorrow. I've now fitted the other supercharger and it's really quiet. Man what I difference when I finally got boosted again :D I've been driving around without a supercharger belt as I've been worried about the noise. One thing I noticed is that once I loosened my old supercharger pulley screws just a bit the 'scraping' stopped and the pulley became much smoother to spin. Tomorrow I will continue investigating the cause and when I'm happy with how the pulley feels I will fit it with a seperate electric motor and see if the noise is still there at 3000 rpm. This is the difference between the other supercharger (left) and mine (right), when my supercharger screws are tightened. Also, it's not because I replaced my screws as the scraping was there even before I did it. Please wait a few seconds for Video to Load! I will also replace my belt (803) with a shorter one as my current belt is tightened as much as possible and it's still slipping a little bit. You can hear it in this video when the supercharger rpm drops before starting building up boost pressure as the bypass valve closes. Please wait a few seconds for Video to Load!

Mine snapped during the summer and it didnt get so cold in the winter to effect meatal - the screws are just crap. Patrick - how did u measure the speed of the supercharger pulley?? Thanks mates! :) To measure the rpm of the supercharger pulley I put a special kind of reflective sticker on it and used an optical rev meter, like this one: I just picked up the second supercharger, which means I've currently got two thirds of the entire Swedish TTE supercharger population :D Anyway, right away I could feel there is a huge difference when just spinning the pulley by hand. The one that I fitted feels a lot heavier to move and it kind of sounds like something is rubbing against something else when moving it by hand. Now I've got two theories; Maybe my former Mercedes colleague is right and the 'blades' inside the supercharger needs some running in to sort of worn off their top layer of paint or whatever they are treated with. I'm more suspicious towards the bearings, though. I have a feeling that they are dry and the first thing I'm going to do tomorrow is removing the supercharger oil plug and check if there is any oil in it. @Rob: If I remember correctly, you've replaced your supercharger bearings once. Do you know where I can find new ones if it turns out I need to replace mine? This is the second supercharger. I didn't have a look at the cf airbox, but I certainly will later on.

Last winter my best average was 39,5 mpg, doing 862,2 km (535,7 miles) on 61,73 litres (13,4 gallons) of petrol :)

Thanks mate :) It turns out there was no leak at all. I started by measuring the rpm of the supercharger pulley in idle, 1100 rpm. Then I closed the bypass valve and saw the pulley revs falling to around 300 rpm while the engine remained exacly the same. I thought that was strange, as the engine rpm should rise when boost is building up. I then noticed what caused this behavior. Both the boost and the noise disappeared because the three little supercharger pulley screws had snapped. I replaced them with M5 allen type screws and the engine became much more powerful again. However, as my boost came back so did the annoying noise. Yesterday I removed the supercharger belt and used a separate electric engine to drive the supercharger without anything else interfering. The noise was present, so now I have excluded everything that is outside the supercharger unit itself. I now think the sound might be caused by a dry bearing somewhere inside it. However, I don't have to open my supercharger up just yet. Believe it or not, but I've just managed to source another supercharger kit only 50 miles from here. It's been sitting in a box since it was lifted from the TTE supercharger demo IS200, used to promote the charged version in Sweden. I've been told that its airbox is made of carbon fiber, but I can't confirm it until later this week. I was also told this kit was bought by a production company for the Swedish movie Livvakterna (Executive Protection), but they never fitted it to the car that was used in the film. Anyway, the current owner will let me borrow the kit, hopefully this week. That way I can quickly replace my supercharger to see if the other one sounds fine :)

I recieved my hoses yesterday, but I didn't buy a kit. www.sfsperformance.co.uk This is what I ordered: 200mm of Ø51mm hose 600mm of Ø60mm hose 200mm of Ø70mm hose That's more than I need, so I can cut them to the optimal lengths. You would need a bit more of the Ø60mm hose, though, as I believe you've got the second generation piping. The total cost was £47

thats not good mate fingers crossed it was a leak then what clips did you use to hold all the pipes on Rabs Thanks mate. I used the simple one that were included in the supercharger kit. I think I might go for some Mikalor clamps, but I'll have to order them.

Here you go, mate :) Silver is a practical color, but I would definitely go with white if I had the choice.

I removed the tensioner pulley but I couldn’t find anything odd about it, the bearing felt the way it should. I also checked my bypass valve and it’s opening and closing correctly. The noise has actually decreased anyway, and yesterday I found it completely gone. Unfortunately, though, that wasn’t the only thing that was gone. My boost had also decided to leave me. My car drives like it has never seen a supercharger. This got me thinking, could the sound have been caused by a small air leak? If so, it might have turned into a major leak, meaning no inlet boost pressure and no whistling sound. Yesterday my new silicone hoses arrived. I will replace the rubber ones today and see if I can get some boost again.

I have to admit I'm not entirely sure what you mean, but mine is silver and I like it :)

You're absolutely right I am, oh my god. My color as well I'm really happy for you, Rolex. That is a wonderful piece of art :D Edit: Might I ask if it's possible to get hold of one from Japan without speaking Japanese?

A few MY.IS members have tried them but I haven't read about anyone who's been satisified with the way they work.

A few new pics :) Info and replies are coming tomorrow, hopefully. Cheers

Yeah, that's what I mean. I really don't think it should be there, but I don't know what's causing it. The supercharger pulls really nice, so it's definitely working. Might be the belt or bearing, even the pulley to tension the belt has a bearing in it :D That would be easy to test. I will lubricate the tensioner first thing tomorrow :) Thanks mate I haven't really thought about it. I only floor the pedal when I'm already in higher revs and the whistling sound isn't present. But shouldn't the bypass valve be completely opened until you put your foot down? I'm pretty sure my valve opens and closes as it should. I just tightened the belt this morning, but I will certainly lube the tensioner tomorrow :) Haha! Yeah, that would be something :D I'm hoping to be able to join you at JAE this summer :)
