If so, the advantage of these is they have toothed gears on the pulley wheels to stop slippage. They are designed for supercharger drives due to the force needed to turn the superchargers turbines. On an XR6T, well, I don't think there would be any advantage except for cosmetic and the 'supercharger' belt sound, but you wouldn't want that on a turbo car anyway.I think that's what you are referring to anyhow????Rob.

Dont think you can get them for an overhead cam engine. I could be wrong though...Chris Link to comment Share on other sites More sharing options...

Geardrives replace the chain and sprockets and give a direct drive via gears, usually straight cut...this is why they have a whirring sound. They use geardrives to prevent chain breakage and slop.A lot of owners get it for the supercharged noise they make. Link to comment Share on other sites More sharing options...
MrBean Member 400 Member For: 18y 8m 2d Location: Melbourne Posted 06/05/06 11:15 PM Share Posted 06/05/06 11:15 PM My 1st post here - helloI know Pete Jackson made a good set of geardrives for 350 Chevies, 351 Fords. They are superior to chaindrives in the sense they don't stretch, resulting in bad cam-timing.Nowadays true roller-chains are getting close to the same reliability as gear drives. Geardrives will have an advantage where very aggressive cams are used, with hefty valvesprings , especially in turbocharged engines where you are running huge 2.02"Intakes, and high bosst-pressures.You will need good quality dual-or triple springs, which will wear out a chain in relatively short time, but geardrives will last a lot longer. They are typically more noisier though, quite ok for the dragstrip, but sh*tty when you go on a 700km trip Anyway same as Zap F6's reply. Link to comment Share on other sites More sharing options...

I was unaware of 'gear drives' as such being available in gearbox or diff, I'll leave that to those that are mechanically minded. The gear drives I was referring to, apparently are 'perfectly timed' and do have certain clicking and whining noise.But thanks for steering me in the right direction though!
