What is this modified pulley? How does it look, any pics?
Now in the 400+ bhp club!

Group Buy on modified Pulleys! I have a cam belt change coming up soon, an ideal time to fitted a modified pulley!

Agree with rog.
I had one of Barbz pulleys, but its just a pulley with an outter lip added maybe 3-4cm max. It will reduce the chance of taking it out, but its not a prevention of this.
Only way you could prevent fully would be with a enclosed section to the pulley, but the cover wouldnt allow this i don't think?

I was thinking of a plate next to the cam belt cover to stop it happening. I really need to look into it to see what's possible!

The ps belt doesnt snap, it derails.
Fitting guides (giant washers) to the pulleys is a better idea, is not impossible to do either.
The acceleration in the lower gears (especially on modded coupes) is so savage that the belt cannot hold on and slips off.
It was a very hard acceleration where it went. Big flame and then BOOM!

What is this modified pulley? How does it look, any pics? I found a pic of the pulley in my Coupé folder . Personally the first thing I did was to cut off that TDC marker which is attached to the timing belt cover and sticks out over the belt. At least it gives it more of a chance for the belt to fly past the cover rather than rip it off . Baz

I'm not all THAT technical, but what would be involved in changing the setup to a chain? (You may start laughing now.) Why laugh, Klaas? It's a very sensible question and one I've considered off and on for years... bear in mind the alleged reason for using belts is quietness from the engine, but I'd be surprised if it wasn't also cheaper. I've been thinking about the 16 with the more fragile belt, of course. You'd need to replace the cam pulleys with toothed wheels to suit the chain, the tensioner idler, the crank pulley, and anything else it goes around - water pump, balance shafts etc. (I'm not that familiar with the 20). You'd probably need to replace the tensioner assembly anyway with some sort of hydraulic device, and you'd have to arrange some lubrication for the chain. A sneaky designer might come up with some way to drive the tensioner from oil pressure and drip feed onto the chain - but you'd also need to scavenge the oil back again, so that might need a better seal on the cam cover unless you wanted a total loss system. The system would probably be narrower than either the 16 or 20 belt, which would give scope for better packaging (the cam chain on the similarly sized Nissan 1.8 turbo I used to own wasn't much thicker than a bicycle chain, though it did require changing due to stretch over a hundred k or so). Snag is, there's a lot of expensive engineering to manage before you get it working. Not impossible, but probably not financially feasible unless you've got one of the last three engines in existence, or you just happened to have an engineering works in your back yard. It's not an amateur project, I fear. But if anyone comes up with a DIY kit for the 16, I'd like one, please! (And for the 20vt, when/if I get one.)

£50? I'll sponsor you. Bike chain doesn't need as much lubrication? Also, it should be possible to have a piece of plastic moulded between aux and cambelt. Maybe something else... we're all looking at protecting the cambelt, but wouldn't it be possible to machine the pistons to make sure the valves don't touch? This might also help:

it's not just the belt - if the aux belt goes then it a few quid to fix.
If i goes into the cambelt when it goes then it's time for a top end rebuild + some new valves, AND and new cambelt + aux belt.....a lot more than £400.

£50 , I never heard about that. I can't believe that people were not keen at that price. If there was a 99% certain way to eliminate this problem I would happily pay several times that figure.

I wonder if a grease chamber could be made,so that the chain would pass through it,collecting grease as it goes. It could have a grease nipple as a top up device. Or is it all to agricultural? I worked on Catapillars for years you see.
