Hello everyone!

Now I did my research, and its a pretty crazy way to describe what I plan on doing.

I am currently building my 1999 Hatch. Fully painted and tucked engine bay, full custom bride wrap interior seats, blah blah. Its going to be at 500hp high boost, for a fun car at the track. (1/4mile or auto-x).


I know that clutch wise I will need something like a Twin Disc to prevent clutch slip. I also know there will be increased clutch pedal feel with anything, even if its a stage 5 clutch.


I am not going to daily drive this car, more like a weekend rocket. But I always have that feeling im going to get stuck in traffic and my leg is going to fall off playing with the high clamp force clutch.


Is there a way to illeviate pedal pressure while mainting something like a high clamp force clutch? I don't mind the rough on/off engagement, more so the pedal pressure.


Can parts like the master/slave cyclinder or hydralic lines be upgraded to ultimetly help push the clutch in softer while mainting its grip in high horsepower situations?

 

Honestly you should just go with a Competition Clutch stg 4 clutch. It held 620whp on my car and the pedal isnt very stiff at all. Almost feels stock. I first bought it 2 years ago when it was making just over 400 and last year I threw it back in expecting to blow thru it on the dyno last year, well that didnt happen. It held up just fine. It is very easy to drive on the street and the price is unbeatable. I'm very impressed with it and it sounds like your best bet according to what you plan on doing with the car.

 

I understand I can go with that clutch, but the main thing I want to find out is if the "system" can be upgraded to make a twin disc or high clamp force disc pedal pressure softer.

 

You could but its pretty unnecessary. There are plenty of people that are running stock hydraulics on twin disc clutches. I have heard that the pedal on the stock twin isnt very difficult to push either though. I can let you know first hand in a couple of days

 

Sounds good buddy, just post here and let me know, in the mean time, I just love testing and getting my hands dirty so I want to find out what people have used and how I can upgrade something to help that high clamp force pressure go away.

 

I run a cable Y1, had a CC twin fitted for a short while then changed it for a stage 5
Both are a little heavier than stock, don't confuse grab with pedal weight.
The twin was a little heavier than the stage 5 but not a great deal to be honest, so on a hydro you should not really worry.

 

Grab and Pedal Weight I will never confuse.

I just assumed, now I could be wrong, that with easier pedal weight, even if you have a harsh grab/engagement/bite it would be easier on the leg lol.

Hey if its really comfortable, I wouldn't mine running it more often on low boost around town.

 

It's hard to describe the difference between the twin and the stage 5, on the street the twin will take some getting used too but it's totally manageable, bit difficult to engage 10/10 times in stop start traffic (compared to a stock clutch) but that's the compromise with any up rated clutch, if you can in fact call it a compromise.
I've used ACT for many years with heavy cover plates in the same Y1 cable box and my left leg used to shake after heavy traffic, now it's not the case, I would dare to say manufactures have recognized the need to make up rated clutches more user friendly coupled with high torque holding.

 

Anything that's going to reduce pedal pressure is going to increase pedal travel...am I correct?
