I have a 59 Giulietta Spider Veloce race car. I am running a Tilton clutch with the mechanical actuator and the clutch is EXTREMELY heavy. My thought was that some assistance from a hydraulic master cylinder/slave cylinder setup would make the clutch lighter. Since its a race car fabrication can be done originality is not necessary. Moving to an aftermarket race setup would be an option.

Do any of our US based vendors produce anything to assist with this conversion. Has anyone undertaken a project of this nature?
I have also considered moving from the floor mounted pedal setup to a hung pedal setup, having difficulty finding info on how to do this and if its even possible.

Any suggestions gratefully received. Thanks in advance.

Hi Gordon. Sage advice. Appreciate the swift response. I have had this Tilton clutch a few years now but it never properly engaged previously and I had all kinds of problems. So I got a really smart engineer to make this work with the engine he rebuilt for me. So now engine is awesome, clutch works perfectly but the driver effort to operate it is massive. I will be honest here I am slightly more vintage than my 59 Giulietta and the fact that with the floor mounted pedals you not only have to press forward but also downward. Thats why I thought a hung pedal arrangement where the effort was forward only plus hydraulics may work. Plus you have the added assistance of the larger master pushing the smaller slave to reduce effort.

My engineer is a smart guy and I will certainly speak with him about geometry changes to the mechanical linkage. We will also speak with Tilton. Final question you refer to F&S Racing who I am not familiar with. Of course I Googled it. are they in MD?

Hi guys having massive problems with the BB on windows ... gave up....so trying from my iPad seems to work here.

Anyways back to the technical. I was at my engine builders shop today.

So Richard it's a 7.5 inch Tilton clutch, aluminum flywheel and GOrdon is spot on I am running a mechanical linkage, with factory floor mounted pedal box. My engineer is in agreement we think it's a leverage issue. I do not have a definitive answer on the thrust bearing. I can tell you it is not stock Alfa. Just to clarify my car is a 59 Giulietta Spider Veloce with a 1600cc '64 Giulia block, with 1750 pistons mated to a 5 speed 2000 Spider gearbox with modified gearbox crossmember and shortened drive shaft. But still running the stock Alfa pedal box with a rod linkage. So it's definitely a mongrel or Mutt.

Did not know cable clutch was an option over mechanical rod or hydraulic. But believe me this clutch is really heavy. The issue I have with the Alfa floor mounted pedal box is you not only have to push forward but also downward and that's a real bear and I believe little mechanical advantage. I just thought that with a hydraulic since you have the advantage of master over slave bore and capacity would help. But I certainly stand to be corrected.

Really appreciate all the help guys and I will see if I can figure out how to send you guys my personal email address.
