The clutch discs use a sintered iron friction material. Sintered iron has a lot of holding power and doesn’t flinch with heat. However, it is surprisingly smooth and driveable, considering that it is a race only material.
The discs use a copper face for good heat conduction. A solid hub allows for positive action, ease of stress on synchros, and they also help a dog box shift better. The flywheel and whole clutch assembly are dynamically balanced as a final manufacturing step.
Our engine is now together. Stay tuned- it is now going to Eimer Engineering to get adapted into the Ariel Atom Chassis (modifications have to be done for intake manifold and dry sump pump clearance). Eimer Engineering will also be fabricating some custom 4-1 merged collector triple-step headers with the help of Burns Stainless.
