anyone know what clutch this is.it came with a tko 600 i traded for a old c-4

 

The disc looks like a Centerforce DFX disc. But the pressure plate looks like a regular OEM style Zoom or Spec plate.

Centerforce pressure plate will have fingers that spread with RPM thats supposed to make more clamping force.

kinda like this one from the TKO in my son's car. But I am not 100% sure this is a Centerforce clutch. If you look in the lower right,.. it too has the Valeo pressed on it.

yea i looked it up you are right it looks like the center force but if i got with the tko600 over the ART CARR C4 ill sell this clutch and get a new setup that can hold more power




thanks

 

How much HP are you planning to make?

The regular Centerforce DF is rated to 700hp. The DFX is the next step up. Darren who used to work at A&E here in NPR has one in his Terminator making 800+ and Terry has one in his Terminator converted to TT making 730hp and both swear by the DFX.

650 to 700 for now till i get a better block.i guess i could keep the clutch and just get a better plate.

 

Not sure how well that would work. The whole premise for the DF and DFX clutches are those finger weights in the pressure plate.

Do some research before you decide on that route. DFX clutch will be in the $600 range new. Regular DF clutch will be $320 for 10 spline and $420 for 26 spline. Zoom's new clutch supposed to be pretty hard core as well. I've used a Spec stage 3 clutch and other than some chattering (DFX will chatter also) it was a nice clutch that held many 6000 RPM bonzai launches.

i take back the 650 to 700 what i should have said was i dont know how much power so whatever 14lbs will give me thats the power ill make.i wont run more then that untill i get the better block.....i know on my 347 with spray i had a ram power grip and didnt have any peoblems with it but im not sure what it was rated for.if i end up going with the tko 600 ill research more about a clutch.ill try and the ART CARR and if i dont like a c4 ill go to the tho600

 

I had a CF DF clutch in my lil n/a motor and it slipped on DR's. Those clutches suck. They have organic material on the PP side and some other type of material on FW side. Aside from some of Mcleod's PP that increase clamping force as rpms increase all the diaphram PP's are all the same (valeo). So if you're going to get a diaphram clutch make sure you get a good disk with some decent material (at a minimum kevlar). Some of the more agressive clutches come with cermaic or carbon and you can get them in a puck style or full face. Be warned, more agressive clutches will tend to engage like a light switch (on/off). You got to give a little if you want it to hold a lot of power.

EDIT: your disk is a DFX like Hurst said. PP looks valeo.

 

thanks either way i think ill sell it and buy all new if i dont use the c-4

 

Looks very similar to the Zoom stage 3 clutch. Cant say thats what it is, plus the PP is not their signature purple but the design is very similar.
