Leadership Team Shortshift Posted January 8, 2023 Author Leadership Team Share Posted January 8, 2023 Wouldn't a BEC need a fd ratio from the other end of the spectrum??Looking for the CSR!James Link to comment Share on other sites More sharing options...
Area Representative Richard Price Posted January 8, 2023 Area Representative Share Posted January 8, 2023 Wouldn't a BEC need a fd ratio from the other end of the spectrum?? No. Most bike engine/'box assemblies have a primary reduction.'Busa has a 1.596:1 primary reduction, so, even with a 3.14:1 diff, top speed is still limited...

Leadership Team Shortshift Posted January 8, 2023 Author Leadership Team Share Posted January 8, 2023 Ah, thanks Richard. The primary reduction explains it.Anyway, back on topic - anyone got one??James Link to comment Share on other sites More sharing options...

Leadership Team Shortshift Posted January 9, 2023 Author Leadership Team Share Posted January 9, 2023 Yes, that's the plan. Replace the 3.38(?) unit that's in the car at the moment with the longer 3.14 ratio to give more relaxed cruise performance with the 6-speed gearbox. Phil and Ollie at Road and Race can't help at present, hence my posts to see if there are any 3.14's available on the market.James Link to comment Share on other sites More sharing options...

Leadership Team Shortshift Posted January 25, 2023 Author Leadership Team Share Posted January 25, 2023 Thanks chaps - saw both of these on ebay and actually followed up on one, but the lack of provenance is preventing me from going ahead. If I could find one from a Club member I'd be able to buy with some confidence, but £1000 plus is too much to risk on a punt.Thanks for pointing them out, though.James Link to comment Share on other sites More sharing options...
DirtBuddha Posted January 26, 2023 Share Posted January 26, 2023 Shortshift: I have a 3.14 Ford diff for sale... but it comes with a Caterham Seven with Hayabusa engine so may be a little more than you're looking to spend Link to comment Share on other sites More sharing options...
Leadership Team Shortshift Posted January 26, 2023 Author Leadership Team Share Posted January 26, 2023 All depends how much you're looking for, I guess! James Link to comment Share on other sites More sharing options...
