Then altering the mechanical advantage on the pedal may be your only option....
unless you pull the engine and see if you can get a slave cylinder with and increase CSA therefore moving the hydraulic ratio back in your favour.
Guessing your slave is hidden in the bell tank in which case providing you can identify it and check this option before pulling the engine sure CC will know which model was fitted originally.
I use the clutch slave cylinder from SBD :Hydraulic Clutch Slave Cylinder 40mm, I think its the one from Titan, they all look the same. I calculated with the surfaces and the stroke of the 0riginal 15mm dia master cylinder I get the required stroke with the this slave cylinder for the clutch. The pedal pressure is OK for the yellow dot clutch cover which I use now with a high tuned 2.1 duratec engine. But its very hard with the red dot clutch cover which is necessary for the torque of the well tuned 2.4 engine I will put in for 2021 season. Anyone ever thought of some sort of hydraulic supporting device?
you could add an indirect servo........
or keep the yellow dot cover and use a cerametallic centre plate which will increase the torque capacity of the clutch, naturally there's a trade off in 'feel' though,
Guessing you will be looking at circa 220lb/ft for the 2.4
AP gave me the following figures based on the stock 5352 organic centre plate
Yellow dot (-1) cover 215 lb/ft
Red dot (-500) cover 280 lb/ft
Cerametallic v organic increases the torque capacity in the region of 80 lb/ft
Yes this could be a solution, I did have for a while cerametallic unsprung 184mm clutch, the feel was ok but the fact that it was unsprung was not OK because of the noise generated in the gearbox and clutch. Thks for your hint will look at it.
On a Manual gearbox you should use the spring version clutch, the solid plate suits better a sequential gearbox.
just read about Hunday electric clutch actuator i.e. clutch by wire
can someone report of a practial driving experience with cerametallic sprung center plate manual gearbox and road (not race) use only. Woiuld this be OK or a great difference and cumbersome compared to an organic plate?
