Clutch Advice

[Dmichels]

I am looking to replace my pressure plate and disc in my car. The engine is a modestly built 440 that I drive hard sometimes, the stock speck  McCloud clutch can not quite handle what I dish out. I have read that many like center force clutches What is the difference between these two?


Centerforce DF269675
Centerforce DF269739

My car 10.5 flywheel 23 spline
Any other recommendations on clutch set ups appreciated

Thanks

I have a ram powergrip in my charger and it has a 10.5 inch clutch in it with the 23 spline tranny and it holds up to my 493 ci without any issues. It has a pretty stiff clutch pedal tho and I hear that the centerforce clutches are not as hard to depress. Several good choices for clutches these days. Good luck with your decision!!

I installed a McLeod Twin Disc RST kit. Works great and lighter pedal pressure.

x 2  But haven't been to the track with it yet . But seems to work great so far .

I was hoping to keep it under $500 The twin disk units are pushing $1000 If I had to guess I am just under 500hp

There are two versions of it . RST and RSX , RST is 750 ish . Pricey but overkill is better in my opinion , especially if you are gonna upgrade anything down the road .

The 739 should be for big blocks. The torque output of your engine means nothing. What you put to the ground determines what clutch you will need. 800 ft lbs means nothing if you have bfg radial ta's on it and a stock clutch will hold it.
   That said, you should run a blowproof regardless of your hp level, if you run stock style radials then the dual friction will be fine. Even drag radials will be fine as they wont hold a stick car. If you run a good bias ply sticky tire and have over 500 ft lbs, then i would say time for a twin disc if you plan on abusing it and want it to live.
  Fwiw, my 12 second 383 has had an 11" dual friction in it for over 10 years on sticky tires and it is just now showing some signs of the abuse.

but overkill is not bad right?  If I wanted the 800HP version of the McLeod even if I don't race or anything , but cruise.  noticed the prices is not bad....

Overkill on the clutch wont hurt the drivetrain.
