Your right about the power these days, Schumacher are even producing stronger belts for their TC's at the moment to deal with it so that 0.4mm might be exactly what we need!

The belts should be here by Tuesday, i'll let you know how they hook up and feel.

Cheers
Chris

Any sign of the belts yet?

Sorry Dale, been away for a few days...

The belts turned up on Monday so very quick service! As expected they don't feel as 'supple' as the kit belts, but still perfectly useable. If it turns out that they are causing some drag on the drivetrain then out comes the old sanpaper

I'm not at the stage of the project yet where i can hook all the belts up, but running them over a pulley they seemed to sit on there fine.

For the price they are perfect and i think they'll do the job perfectly too.

Thanks again for the link.

Thanks for the update, sounds like they'll do the job. Still can't believe how cheap they are (about 1 per belt for anyone else reading)!!!

I'll get mine ordered shortly and see how they go.

It certainly is cool to see some real dimms for belts like those used in RC cars and industrial applications - I always wondered specifically how the tooth was shaped. Thanks all for this interesting discussion.

Quick update from me. Ordered my belts on Thursday; 9 belts cut to 3mm width came to under 10 (so about 1 per belt, amazing!). And they arrived Saturday morning less than 48 hours later, absoutely fantastic service from these guys.

Very pleased with the belts. They are slightly stiffer than the ones normally found on touring cars, as they're about 0.2mm thicker overall, but the tooth profile looks spot on and I'm sure they will free up with use.

Here's the website for anyone else wanting custom belts (or just strong, cheap belts; these things definitely won't snap):

These guys are the saviours of the DIY car builder!

Agree with Dale's sentiments - great company!

Dale, what do you think of reducing the width to 2mm? With the extra thickness of these belts could we use that to get a little efficency back?

It might work, if you could reduce the pulley width as well. If you don't do that the belt will flip over (I tried a narrow belt on wide pulleys once before, it didn't go too well!).

I'd also be concerned about it slipping more as there will be less grip between the pulley and teeth.

So overall I think I'll be more likely to just sand them down to reduce the thickness, although to start with I'll just run them 'as is'. If my prototype car handles crap then it won't be worth spending time making the belts more efficient...
