Hey all....im thinking of putting on toothed pullys or micro v belt kit...
Anyone had any dealings with any of them.....ive heard bad things about the toothed kits buggering up the charger but im looking For advice...
-
Each person had there own opinion. I ran toothies an never had a problem. I swopped belts every 6month to make sure everything was good. Plus toothies were invented by vw motorsport why would they use them if they wasnt better? But like i say each to there own its like asking whats best standard or doing the boost return mod
-
I've had them on mine for seven years, and (touch wood) I've never had any problems.
Admittedly it isn't a daily any more but it did about 13,000 miles in the first year after they went on, didn't throw a belt or knacker the charger then, and hasn't done with several track days behind it. I much prefer the power delivery (though I prefer the noise of V-belts) and don't have to worry about over-tightening the pulley against the main bearings (which is just as bad, and a problem for V-belt setups).
BUT I don't hit the limiter, and I don't stab at the throttle like a maniac. Use a bit of mechanical sympathy and your car will thank you for it.
-
Thanks lads.....ill have a look into some kits....alex...u said you liked the noise ov v-belts...u mean the original set up.....?
.i heard That toothed belts are ment to make a nice noise too or is this rubbish....?
-
They make a good noise, but I like the deep whirr of V-belts (the standard ones) more. Just personal preference.
-
I always see people saying "I've heard stories of people blowing up chargers", but I've never ever met one of these people it apparently happens to all the time. I reckon it's no more than hearsay and rumours.
I ran toothies for years too, including when my car was a daily driver and on several track days. Never had any problems at all, never even had a belt snap.
It's a combination of buying a decent kit (i.e. not from ebay), using a belt with the correct tooth profile (i.e. not a timing belt), not over tightening (less than v-belts, much less, more like tensioning a timing belt) and replacing the belt every so often as a preventative measure rather than just keep running it till it snaps (again, like you would with a timing belt).
As for kits, mine was one of the very first sets that PSD sold so was the same as the "phase 1" set that Pete sold on here recently. If you see one of those kits then just buy it, they are the best.
-
the only toothed belt kits i can get hold of are from bar-tek and max-rpm...both look ok kits.both with steel pullys..has anyone seen these or had one...?
And does anyone know the real difference in profile of a timing belt and the toothed pully belt as some kits ive seen use a, gates 20mm optibelt....?
-
The only kit iv run is a bartek kit an they seem pretty forgiving on the belts aswell. Never had psd items so cant comment on them
-
One of the advantages of running toothies to me is also the lightweight of the alloy ones so I personally would wait for a set of PSD ones to come up. Thats just me though.
I have also run toothies for many miles and never had a problem with them apart from the odd belt issue but thats becuase I'm tight and waited for the belt to die before changing it. I would say these days I prefer the v belts myself also becuase you can actually hear the charger rather than just the belts.
-
Thanks lads....wear would i even get a psd kit from if i went for that one...ive searched everywear to look at one but carnt find anywear....
-
at the moment im running the standard setup. i asked for some new belts fitted when i had the charger serviced the belts are obviousley v belts but these have no teeth on them there just flat....anyone run these b4....
-
I've got the bar tek steel toothies kit and really like it, it's louder than the alloy ones but personally think thats better
They also come with proper conti grip belts and are really well machined, had mine on for about 10k now with no troubles and I've driven it hard
Think I paid £150 new which is pretty good when the belt alone is nearly £30!

Running Bartek pulleys aswell with no issues, sound cool as aswell!

Must be because it's steel or maybe the profile is different but it sounds alot more epic than alloy :) going through tunnels in Switzerland was awesome!! All my mate in front could hear with his roof down was the charger screaming through the tunnel haha :D
-
I got the bar-tek toothed setup last week..all steel pullys....need to sort other issues out with the engine and charger b4 i can put them on.
-
Most people run 65mm pulleys, has many ran a 60mm pulley?
Is there much more gains to be had? Im not planning on doing this just wondering.

its not recommended, i remember mr mirfin telling me the bearings are rated at certain speeds, and the 60mm pulley rotates the bearings faster than what they are rated at redline or something
even the uprated bearings
plus when i ripped my charger apart for the second time the grease from the wiggly eye bearing or whatever its called had displaced and was dry. im assuming this is because i over revved it (my redline is 9.5k for some stupid raison)
-
I've had toothed belts for around 10 years and put about 8-10k on in that time with no issues. I know Jabbasport don't particularly liked toothed belts and suspect they won't honour a warranty if you have them fitted. That's the only negative comment I've ever personally heard about them.
I've also heard pulley size shouldn't be lower than 65mm for reasons already stated.

Soooo
Was singing Barteks praises....
Started the polo today after finally putting it all back together and after a horrible and baffling rattle it looks like the alternator pulleys guide is splitting away from the pulley, causing it to vibrate.
Not sure if its the pulley thats loose also but I shall be able to report that back next week
:(

Sounds like the same kit I got.
My alternator pulley was just fouling off the ARB bracket.
A quick seeing to with a grinder soon gave me enough clearance.
-
Mmmmm...will have to have a look at this when i put mine on.

This is actually the cause, cheers to alerting me to it.
