twin V or 6 rib belts are fine but Id really prefer a gear drive
for perfect timing and all rpms, apparently some speedway people
had done it with chev kit.

You can gets kits from Japan. But you're better off adapting one.

You want perfect timing and rpms for your water pump? These belts do not drive the camshaft or the distributor.

Nah mate but sometimes a sloppy chain does :)

What is/are the benefit/s of a Gilmer drive set up?

The belt doesn't slip and it sounds good.

So they are basically a wank?

I've never had a properly adjusted fanbelt slip.

Might be a must have for running a supercharger, look pretty cool too.
Might be wrong but I see no other benefit.

a mate put a gilmer drive on his 202 once, he just liked the sound coz it sounded like it was supercharged haha

Yeah people just throw them on cars for the whine, i know of several 5 Litre commonwhores runninng them (they do sound tough, I'll admit) but I don't think they increase power or timing etc.
