Kraftwerks Supercharger Owners Thread

[projek_01]

My whine at idle is fairly quiet. I was able to rid of the whine at idle but the belt slapped around a bit. The whine is definitely noticeable as I accelerate though. I believe that is normal.

You are loosening the bolt of the idler when you are adjusting the tension right?


no whine idle for me, we just really need to find the sweet spot. If it is a little loose, no worries because it's cogged.

It's not the whine noise, cold start is fine without noise, after driving a bit, the noise came really loud, I'm loosing the bolt for tensioner Even the bolt not touching the idle pulley, it still making the noise

[scionfr_s]

Another video in the day light, I did adjust the tension a bit but it seem doesn't make any different at all

Just picked up my Kraftwerks SC last weekend! Waiting for my FRS to get back from the shop to start my install

@zoth according to KW a loose belt will have the same issues as overtightened belt as either way it's an extra load on the belt. so you should worry if it's too loose.

@scionfr_s did you read and check all that people have already suggested? otherwise you can post a new video every day - it won't fix your problem.

for belt tension try this:
- unscrew tension pulley bolt, just enough to be able to slide the pulley
- unscrew the tension bolt
- manually slide the pulley forward to tighten the belt and tighten tension bolt with your hands. Do 1/4 turn on tension bolt to tighten it some more.
- tighten the tension pulley bolt
- check the belt tension with gates phone app, it should be close
- if needed, unscrew the tension pulley bolt and adjust a bit the tension bolt, screw the tension pulley bolt and recheck again with gates app

Of course not too loose, enough to get rid of his noise. A better judgment on his side will be needed. Gate's app sure will help, but it's very inconsistent.


I wonder what will be the equivalent of 60.7 HZ using a electronic guitar tuner?

Guys.... If anyone is looking to upgrade from their C30 to a C38 I have one for sale. Shoot me a PM. Used for approx 75kms. this thing is practically brand new. I stripped one the screws on the pulley mounting bracket like a dumbass and had to send it back to KW for repair, which I give a huge thumbs to CJ for his awesome customer service, he will be fixing this under warranty. The reason im selling, this got lost in the mail/held up at customs for almost 4weeks, I was with out a car, couldnt wait any longer and ordered up a brand new replacement. So my original found its way back to me this past tuesday and is on its way back to KW for the repair, and should be back in roughly 2 weeks If someone wants it.

asking 1600obo cdn... so you folks south of the boarder from here can take advantage our low cdn dollar.

This method really helped me dial in my belt today. Thanks @vgi

My belt was way too loose before I think. I was getting belt powder on parts near the SC plate. I also thought the cogged pulleys were the reason why the whine went completely away, after switching from smooth pulleys. But seems like my belt was just too loose.

I also couldn't get consistent results on the gates app because the belt was so loose. I'd pluck the belt and wouldn't get any results, or it would jump from 15hz to 120hz or something like that.

After using @vgi method above, I was able to actually get the gates app to read a consistent result. It is reading 55hz after every pluck (as well as I could actually feel it resonate now).

I'm going to drive around for a week or so and check back if the hz stays consistent (or my belt breaks from being so tight now). If it's still 55hz I might try and dial it into 60

Edit: well now that I measured the bolt, it's 19-20.5 mm depending on how you measure it exactly. So that puts me a little more at ease about being the correct tension now. Plus hearing the whine again is awesome!

Don't be alarmed but the belt will stretch some. I've adjusted mine a couple times now, just a half turn off the adjuster each time

[vgi]

the belt should whine a bit at idle (although my idle is at 900rpm).

if the belt is too loose you would hear kinda grinding noise (has been mentioned in the thread) at low rpm when starting to move, i still do a bit.

the belt does stretch a bit, i though decided not to readjust it for now - perhaps KW have encountered for it? or not, then adjustment really should be made.

If anyone is interested in a C30 to replace a damaged unit? I'd sell mine to buy yours!

Stuff like this should go into the first post. A section for "Common Issues" and "Common Fixes" would kill a lot of the noise in this thread, especially when the exact same issues (especially belt noise/tightness/looseness related) keep popping up.

It could be something simple, like links to the post for "Reducing belt noise", just like the link for clamping hoses so they don't pop off. We should make it easier for (new) owners to absorb some of the accumulated tribal knowledge, not force them to go through 150+ pages of mostly drivel just for the few good, relevant posts to whatever issue they're having. Searching through all that is tantamount to hazing.
