Centerforce DFX or Dual Friction please chime in - Lateral-g Forums

**NorCal72** · #1 09-24-2013, 11:23 AM

Wondering if the DFX will be to aggressive or have to much chatter. Application is a 600+hp supercharged Gen1 383, LT t56, Detroit 4.11's,
335's in a Gen II Camaro.

Some road race/drag/autoX but it will be driven on the street a lot.

Thanks in advance for any input.
(I've asked for opinions before but I'm getting ready to drop the hammer and want to make sure. Sorry for being repetitive.)

Ive used them both, the DFX will chatter your teeth, I wouldn't recommend it on the street very harsh on engagement.

The dual friction is a decent clutch might just be outside your power requirement, if you decide on this one explore the possibility of fitting a 12 inch pressure plate for more clamping force. I believe it will fit.

I love my DYAD, never chatters, has great street manners and enough grip to hold my motor and yours combined.

Mcleod rst/rxt is a good piece as well.

That's the issue, with my Gen I SBC/LT1 conversion flywheel I have to run the LT1 clutch setup. Centerforce doesn't make DYAD for my application, McLeod doesn't make a RST/RXT option either. The Centerforce dual friction seems to be the best option. However, I agree with you on the power being a bit too much for that clutch. I've looked at the SPEC Stage 3+ as well but I've read a lot of mixed reviews. So confused LOL

Give the guys at centerforce a call. I Think you will be ok with the Dual friction. I ran it on a 540 cu in, Mitchell BB making near 700 ft lbs. It performed great, it wasn't until I made 5 passes with a set of Hooser QTPs hooking hard at the drag strip that I started smelling friction material. Real nice on the street, you more than likely will blaze your tires which takes a significant load off the drivetrain(clutch). Even the 335 r888s on my camaro with 500+ rear wheel blaze 1st and 2nd gear effortlessly, its just not as much impact on the drivetrain when the tires spinning.
Good luck- Rich

I was on the edge and slipped occasionally running a dual friction with my 90 corvette and a 400 roller cam motor with 315 R tires. With even more torque and sticky tires I would think you stand a good risk.

More conflicting, but great info. Im totally undecided on which way to go. Thanks for the replies.
