Do all g60 injectors fit my g40

why would over tightening toothies wear charger bearings? if thats the case v belts must be doing masses of damage as i used to have to tighten the shit out of my twin vbelts putting alot more stress on the charger bearing than over tightening toothies
if you get me? ran toothies for about 7000 miles now, never had a problem (other than ripping my timing pointer off)
sound nice too
never hit the limiter. then again i have a psd chip and apparently the limter is 9k!!! but im a whimp and change at 6500rpm max when hacking it

The ones I've seen have been on '60's. Toothed belt kits do seem to work better on '40's but still aren't recommended by most specialist (they may sell them) but if they're honest they won't advise them.

The fact is the v-belts will snap long before a toothed belt will, the tensioning setup on a 40 just doesn't let you get loads of tension, hence the toothed kit working ok.

Where as fitted to a 60 a solid tensioner is required, these can easily be over tensioned, pulling the main shaft off centre, it doesn't take a lot but enough will allow the displacer to contact the casings.

So yes it's down to making sure tension is fine but no toothed belt kit I've seen for sale comes with instructions of how to tension bang on (because it's just a trial and error job) but it's not a job that should be!

I'm not going to argue they're crap as they do do a job, but it's just something I'll never recommend and a kit I see as more of a money maker than eradicating an issue, VW tested these chargers in Motorsport long before they hit road cars and didn't come out with using toothed pullies which is where issues of belt slip would of come in.

But each to their own

I was always under the impression that vw motorsport came up with toothed belt kits :s
Im sure i read an article on it somewhere.
The reason i like toothies is you dont have to tension the belt lots so your not stressing the main bearing where as with v belts to get rid of slip they have to be pretty tight.
But as stated each to there own like the ptfe spray subject some swear by it some hate it
Marmite!

Me too, but the link I had years ago is dead. BarTek and MaxRPM both credit VW Motorsport with inventing them too.

In fairness, PSD used to tell customers buying toothies to tension them up like a cambelt - it's hardly rocket science. They're far superior on a G40 than a poly-vee setup, no slip and easier on the 'charger bearings. Only downside was increased noise and less tolerance to pulley misalignment than a v-belt.

[hayesey]

does anyone have any examples where damage to a g40 could be put down to the toothed belt?  I've been around g40s for over ten years and have heard people saying "oh they're bad" but never, ever heard of anything actually happening.  I'm with Andy, less tension is easier on the bearings.  I'm convinced the only reason VW themselves didn't use such a set up is because of the amount of noise it makes.

Depends how it's driven surely? I bet snapping the throttle on and off won't do it any good on the toothed pullies

Why?

[gaz g40]

Im with yoof on this as the pulleys are run by the crank rotaion anyway so its not as though its snapping as you put it. Or am i totally off the mark?

[z3i]

snapping the throttle on and off wont do anything, it doesnt sound the best but going round 25 hairpins one after another up the stelvio is a constant full throttle, snap off, straight back on for like 30 minutes and mine is fine

jabba dont recommend toothies as if something in the charger breaks they will carry on and destroy it more where as v belt will slip, but to be honest if the charger was to break and stop turning.. its gonna be pretty annihilated anyway

yeah i agree, toothies are pretty loud, vw wouldnt want that from factory

I used to quite enjoy driving like the Polo like a cunt. Also grenaded my fair share of decent laders. Some would take it. Some wouldn't. Coincedently, one car I gave death everywhere had multi v's, never blew it's charger. Maybe just a good charger. Maybe the pullies being a tad more progressive. Who know's, as let's face it, no one has done enough miles on 2 equal laders to say realistically. Don't get me wrong they're a large improvement over v belts, and a lovely noise, but how many bearings are there inside a G lader? All running at what sort of tolerences after however many millions or billions of revolutions?
