Transmission

This is covered in the instuments and controls section.

T.B.C.

Bike engines require a lot of gear changes when installed in a car and they are not really smooth gear changes either, especially relaxed gear changes.

If you are not going to use a chain drive from a bike engine, then you are going to need a sprocket adaptor. If you are going to use a chain drive, then you will still need a sprocket adaptor to take a bigger chain. A motorcycle chain is simply not going to handle the forces resulting from moving a heavier mass and the greater traction (from two tyres).

The move from a front-engined car to a mid-engined car means that no heavy prop-shaft is required down the length of the car.

With a mid-engine install, the bike engine is going to be mounted transversly (in the same direction as it would be in a motorbike), so that the output shaft is pointing to the side.

This is an interesting electric car build that has got me considering using a kevlar belt drive. This technology has moved on massively in recent years.

Differential

With the lighter weight and increased power, I plan to install a Limited Slip Differential (LSD) from the outset. The differential ratio in my Fisher Fury R1 is 3.38:1 and this is just about perfect.

The combination of engine, gearbox, final drive and wheels & tyres is optimised for acceleration and a fairly low top-speed. My Fisher Fury R1 will reach its 130mph top speed on track and with improved aerodynamics and more power, the planned top speed of approximately 150mph is very realistic.

The new IVA test dictates that cars now have to have a reverse gear. This can be an electric reverse and it only has to move the car a few feet on level ground. This now also means that the car needs a reversing light.
