supercharger belt sliping

[BoostedK20]

Ok so 04Turbospec and i recently just replaced my supercharger belt on my RSX. Ever since we replaced the belt the damn thing will not stop squeaking. It onlt squeaks at low rpms and when i turn the steering wheel from lock to lock. It also wont hold boost, it should be boosting hapily at 7lbs but the belt just slips and drops to 4.25 or 5lbs. I dont understand it's a brand new belt all the pulleys are good and the belt tension is perfect. If anyone has any sugguestion or advice it would be greatly appreciated.

have you tried upgrading to a 7 or an 8 rib pulley and belt?

Where did you get the belt from? Sometimes the supercharger company will use an odd sized belt.

he already has a 7lb pully on there

im not saying that, im saying a pulley of the same diameter that has more teeth

What type of belt did you put on there?
Sometimes, the "cogged" belts work better than the "non-cogged" ones.
This is one of the biggest problems with superchargers, the belt slipping.
Many times, you can only make so much boost on a certain width belt. A few of my friends with dakotas couldn't get any more than 12 PSI on a centrifugal supercharger, before the belt started slipping. Even at 12PSI, the belts on lasted for a few runs down the track.
And typically, once the belt slips, it glazes the rubber, and you loose all grip.
Try another style of belt, I've had alot of success with dayco's poly-cog on my dakota when I ran N2O. The goodyear cogged belt was supposed to be pretty good, but pricy.
Hope this helps.

i ordered the exact replacement belt that came with the supercharger when i bought it, thats why im so confused by this problem. The supercharger should have no problem holding 7lbs of boost i know people who run 11lbs on an rsx using the same blower and belt that i do who have no issues.

you sure its the belt thats causing the problem? my jrsc had the main bearings go. maybe something else is binding up and causing the belt to slip.......I also know the tensioner i had on my jrsc wasnt the greatest thing I had to tighten it every few hundred miles.....

maybe but my superchargers only been on the car for 6 months. Could a bearing already have gone bad on it?

New belts stretch, you're going to have to keep tightening it until it stops.

<-- Used to have a JRSC.

yeah i had to tighten my jrsc belt every week, it had the worst tensioner design on the planet

i forget the company, but i know there is one out there that makes a belt tensioner that replaces the jrsc one, and it doesnt loosen up over time. let me try to find the link

[BoostedK20]

yeah find that link for me if you can

[specialgoodness]

we're talkin a manual tensioner and not an auto right?

[BoostedK20]

yeah it's a manual tensioner

tighten it up.. alot of people put vht on the belt too...cog setup is way too serious for someone who is only running 7lbs(but if your 6 rib and can upgrade to 8 i would definatly do that, might see more that 7lbs too)... sounds like you should just drop the belt down one size if your tensioner will allow you too.. pry it on if you have too.. keep in mind though you want that belt real tight but if its TOO tight its going to warp the bearings inside the blower or whatever else the belt is attacked too on that setup (not familiar with rsx supercharger belt route)

[AMF Racing]

adding something like vht or belt dressing is only a temp fix that in the long term can actually cause your belt to get glazed and slip worse. it also wears out the belt a lot faster cause it eats it. just keep tightening it, it will take a good few hundred miles at least on a new belt before it is done stretching, specially in this cold weather.

I've had my supercharger on for about 5,000 miles now, and have never had to adjust the belt tension. Would a shop have tools to accurately set your belt tension? I'm sure an Acura dealership won't adjust your supercharger belt, unless you know somebody. Dealerships can be such a pain when it comes to anything aftermarket.

totally different designs between the k motors and the b motors. jrsc for b series had a much better design imo.....k20's have one belt while your motor has 3. i think thats the main reason why they slip more on the k's.

Gotcha, that makes sense.

the b had a better design b/c there is alot more room work stuff to be added. for what it is, the k-series supercharger brings much better results than the b-series does

i agree 100% it makes more power, and is a nicer blower, but the tensioner due to the room/one belt isnt nearly as good as the older style.

true, they should come up with a better tensioner design. i believe one company did that, but i forget thier name. just make sure to not overtighten the tensioner, it could break

heres a concept, would have prevented all this: listen to your mother when she says you should have gone turbo. The volvo is turbo, and its got PLENTY of get up and go, not to mention e-brake snow drifting.

[Evo8kid]

O and you drive a honda that beat 240, thus youll have honda problems like the 240

pulling up the e-brake in a fwd car and letting the a car slide, isnt drifting.

[Evo8kid]

chill man, its cool its his moms volvo, awd, in the snow. Let me more politically correct to please the younger crowd...would you rather me say slide around in the snow? Does that make you happier? and yes he does pull the e-brake something fierce.

[KawBoy]

My blower is doing just fine..

But I got a B ;)

[BoostedK20]

yeah so it turned out that my one of my upper brackets came loose and was crooked therefore throwing off my belt, and the lack of tension. Now that this is fixed all i have to do is buy a new clutch cause it just blew.

[AMF Racing]

at least you got it figured out. once i get my cams in I want to run you for fun. hell I'll run you pre-cams :)
