I'd like to build a BEC and Im doing my research into it. Ive come across the
Quaife PowerTec gear drive:

Which is priced around 975pounds.

Ive noticed some here have use a chain drive.

Whats the plus minus of each system? This Quaife looks pretty good.

Thanks for your reply.

reverse on the gear drive looks handy

If you are going middy or rear engine, then chain diff is a cheaper option.
I have an xr4i 4 X4 lsd diff.

Hello Nitram, Thats one of the reasons why I asked. When I first did the research I saw the Quaife, then after spending a few hours reading everything here(almost) I saw your car and asked the question. Apart from price, why is your system better?

I would think that is lighter (not sure) and I can change my final drive ratio by changing the rear sprocket.

Powertec website says 2490 gear drive, 1290 chain drive, and thatīs probably ex-vat.

975 would be cheap!

Which engines does the Quaife fit? I've only seen it for Hayabusa so far.

Yes, sorry I was wrong. He gave no link from his email to his site and I got the products mixed up with this one:

http://www.quaife.co.uk/Yamaha-R1-1000cc-6-speed-gearkit

sorry. So with the correct price I might just stay clear of it.
