I'm one of the few who has had no problems with the Centerforce Dual-Friction in a 1987 Turbo II.
The engine has never made over 300bhp.
I would never recommend the clutch to anyone making close to 300hp at the wheels.

The clutch looks like you need to be very careful on break-in.
I happened to break my clutch during a fresh rebuild, so I took it easy over 2,000 miles.

After the careful break-in, I did not hold back, but max power was only 253hp at the wheels on a DynoJet.
The car and clutch survived a brutal 30 minute session at the drag strip which involved 17 runs and trying to dial-in my launch.
(The dial-in involved drag launches from 3,000RPM up to 6,500RPM with varying amounts of gas pedal and clutch slippage.)
Even through launches that wheel hopped or "smoked" (i.e. burnt clutch smell), it never failed.

I've pulled the trans 3 times so far, and inspected the clutch (disc) every time.
So far, nothing obviously wrong with it.
Wear was even, but due to all the drag launches, wear is obviously greatly increased.
At 20,000 miles, the clutch was already 3/4 worn.

The car recently put down a leisurely 240hp on a Dynapack dyno, which when adjust for DynoJet #'s is actually more than the earlier 253 level.
240hp Dynapack + 10% conservative adjustment puts it around 265hp DynoJet.
The car has about 30,000 miles on it now, and I expect to replace the clutch soon.

Problem with ACT...
Unless you have GOOD hydraulics, the heavier ACT pressure plate tends to blow your clutch hydraulics.
Even if you have good hydraulics, the heavy pressure plate just wears the stock hydraulics prematurely.
The ACT (pressure plate) also tends to kill pivot balls on FC turbo transmissions.
I do have an ACT...just in case.
...but I'd rather go twin.
I've driven OS Giken and Carbonetics, and they are bad ass.
Superior clamping force...
Less wear&tear on hydaulics...
Easier on the leg...
And it's probably the last clutch you'll ever buy unless you go 20B...

this info is as accurate as its going to get.. well said Ted

Yup yup.... kept her inside for the storm ;)

Thank you....

Yeah.... I killed one on my old n/a FC....

Not likely.... snow on Thursday ;)

:rofl:

Yup yup.... except I've never had problems with the ACT HD PP, the Extremes are known to kill hyrdo's and pivots, the HD's seem to be ok

Same thing happened to my centerforce. let go in spectacular fashion at Mosport DDT in Ontario Canada.

Now run a Stage III Bully Clutch in my 10th AE and a Spec in my 1989.

I've been running an ACT 6 puck ceramic clutch for a few years.
Last year I had to replace it because the first one had worn out.

My FD doesn't make huge power, about 350 RWHP, but as it is an autox car it gets driven pretty aggressively.

The 6 puck is kind of hard to drive until you get used to it, but once you do, it is a piece of cake.

I'm an ACT guy, has done well for my 400RWHP car.

I love my ACT as well.

Sorry to hear about your Centerforce but thanks for sharing! Thankfully no one was hurt.

The centerforce worked well with small power but once the power went up it showed why the pedal effort was so low not enough clamping force. The ACT is in and the car has been dyno'd at 410 Hp to the wheels and now the tires are slipping while it was strapped down.

Slipping 90% of the way through 3rd on the dyno..... you steer this car ith your foot :smilielol5:
