Title: Clutch hydraulic ratio
Post by: FC427 on March 02, 2011, 10:41:28 PM
Has any one played with the hydraulic ratio between the master cylinder and slave cylinder on there FE FC to make it lighter  ??? ??? ??? ??? this is not relevant to a standard small clutch  but with my new blown engine i need a fair amount of clamping force to cope with the torque .....FC427.....

Hello
what clutch fork are you running , I had a HR with a brass button clutch & i kept on bending standard  Holden  M20 & M21 forks i had one made up  , I think my master cylinder had a slightly smaller cup in it ,

Modify a nissan patrol or skyline boosted clutch maybe they are very small in diameter and run on vacuum like you brakes???

Mark,

I think an EJ Slave cylinder is larger in diameter, I stand to be corrected.

Cheers
