Default Re: Hydraulic Thow out bearing

Tom,
I'm putting together a Drag Pak stick with an hydraulic system to try. Using an adjustable stop on the pedal for air gap setting.

John

I am building one that is both hyd. and mechanical.
A mechanical t.o. bearing and fork pushed by a hyd. slave cylinder.

I wonder if this is legal ?

I am interested in what your are doing with the hydraulic cylinder, in whether it will be quick enough, and how big a cylinder, and how big the bore on the master cylinder. I run a hydraulic throw out bearing, that uses no fork. I don't run stock or super stock, but it is legal in my class. I don't see many hydraulic systems, except on the new cars. Very controversial. And what type of fluid you plan on using. I don't believe I would call this a hydraulic throw out bearing, I would call it a clutch hydraulic slave cylinder. Hydraulic bearing won't have a fork

Alan,

I would check with your division tech director and get clarification from them on legality. There are a few reasons why you would not want to run a hydraulic setup even if it's not a class car.

Do you want to go rounds and consistently cut a light? It's hard enough with a mechanical setup to cut a light constantly, then add the reaction rate of the fluid and those components. Depending on the ambient temperature, the viscosity is going to add another factor on your reaction.

Either way, good luck.

Sean

Its the 009 car that a friend purchased that I'm going to run.

I used an hydraulic system with a fork in my stocker Dakota since I built it in 95. NHRA had no issue as it was the production set up. They did look it over for and solenoid in the system.
