We need a Beta Volumex supercharger drive belt.
Any idea where we can get one?

Assuming you have one to measure, just search online for the type of belt you need - shouldn't be to difficult....

I no longer have my copy but I seem to remember that there was a spec for the belt in the tech section of Guy Crofts book on the Twin Cam. Perhaps someone else has a copy?

It won't be a standard Volumex belt as that has to drive the power steering pump too. All you can do is measure the old one or the belt run route?

Used to get mine from Fenner belts all those years ago, I may even have an old copy invoice somewhere but I'll have to dig it out for spec plus I used the old power steering pump drive cog, machined out and fixed over the crankshaft pulley to speed up the supercharger 15% or so which might mean my belt spec is too long?

Thank you Guy, that is helpful...

Just had nostalgia trip through the file of invoices to see if I could find it but there's nothing there. I think I must have given it to Dave Watson when he bought the old engine off me for reference.

I'm sure that these guys will be able to help if you can give them the tooth size and belt length.
