Title: New clutch - McLeod, Centerforce or ??
Post by: torredcuda on May 21, 2018, 10:09:05 AM
I had a Centerforce and it held up extremely well to 20+ years of street and strip abuse but it`s finally time to replace it, should I stick with Centerforce or try a McLeod or some other brand? I do want to stick with the diaphragm type and the McLeod is cheaper but is it as good, and which part number?

Well my experience with a Centerforce lasted a weekend & if you shift hard & high rpm the pressure plate will invert & stay there so you need a rev limiter .
I toss them in the trash , just junk  :Thud:
My favorite is the McLeod Borg & Beck / long series , proper pedal feel & & will always return

I have to agree with CP. I have bent a few of those Diaphraghm setups, I tried one centreforce and it didn't work for me.

I do not like the diaphragm style at all :thumbdown:

But your answer sounds obvious....You've had Centerforce for 20 years, why switch now ? to save a few bucks ? :dunno:

I really like my centreforce diaphragm clutch. It's been there over a decade so far and never failed me. Maybe I don't treat it as rough as CP or runcharger?
Those guys are probably just hard on their cars...lol

Or maybe we build more powerful engines  :thinking:
After the first shift where the clutch pedal stays on the floor it is time for the trash , better have the rev limiter too or the engine may be trash also

I probably don`t have near the HP as some others, it`s just a basic 340 running low 13`s on street tires but I beat the snot of it powershifting at 7000 rpm, 100`s of drag strip passes and generally beating on it on the street and never an issue till it finally gave up. I figured McLeod was always a good name but not sure how there diaphragm set up compared to Centerforce?

I have a Mcleod and I am very happy with it. Stock 340, I just drive it. :)

I wouldn't use a diaphragm  :alan2cents:

I do drive my stuff as Mopar intended. I had a Corvette once and drove it like a Mopar. It couldn't take the abuse. That's why I liked them back in the day. A Mopar might have a rattle in the door but the power train won't let you down.

 :iagree: Totally  Mopars were always better engineered , drove them hard too , broke lots of Mopar parts hate to think how many parts the Gms would have eaten up by comparison !!

I think the BB long has been discontinued.  I use that and can't find another. If anyone knows differently, please let us know.

The street twins are good too , I have a B&B Long twin in my car right now
too bad they discontinued it , best design & the only company making it . I Guess I couldn't sell enough to continue building them  :Thud:

I like the B&B long also, sucks they discounted it.

Here's my 2 cents. I absolutely hate stiff B&B pressure plates on the street. Especially when I'm getting to run somebody and my clutch leg gets to shaking from adrenaline. I'm sure some of you know what I mean! Some won't.  Anyway I have run Center Force clutches since the 80's and never had a issue. The early versions were basically a GM spec piece and if you didn't use a pedal stop and pushed it to far to the floor it wouldn't return under high rpm. I'm guessing that's what CP has run into. The later units are specifically built for Mopar and don't require a stop. Just remove the over center spring on the pedal assembly. I'm pushing just shy of 400hp with a 340 and shift at 6400 rpm. Zero issues. The clutch works so good that under hard acceleration and shifting normal it will bark the tire in every gear including 4th.  Obviously I like them. I also heard they discontinued them so supplies may be limited.

Sp the CF is discoed, the borg and beck is discoed and the hybrid is discoed too? This really sux.
Shane, when waiting to sidestep or drop it I don't even notice the effort!

But on street tires that's only good for smoking the tires off :burnout:  I'm all for that also and do plenty of it. Let's say hypothetically somebody is beside me on the street. Dumping the clutch only gets you a view of tail lights. I prefer to slip the clutch in that situation.

I don't slip the clutch , I either make sure I am the right rpm to hook up or have decent traction
Title: Re: New clutch - McLeod, Centerforce or ??
Post by: RUNCHARGER on May 26, 2018, 07:47:28 AM
I slip it a bit with street tires too but I don't like doing it. If I figure I have the guy covered I walk it out of course. Automatics are easier to race but not half the fun.
I didn't realize almost all the clutch choices are gone. That's concerning, A $1000 clutch adds a lot to the bill. It cost Greg $10,000CDN to do the changeover 2 years ago going to the dual disc and OD4 speed. If you don't have the time to chase deals on used parts it is getting unrealistic.

I know the owner of McLeod is a Die Hard Mopar guy might be worth contacting him as a group / website & see what can be done ?
The B&B Long was only made by McLeod , no one else ever created that combo .

Looks like they still make the B&B Long for truck pulling / sand drags with non-shift type transmission so maybe that can remake for Mopar.

You could drill the holes in the flywheel & just mount that pressure plate
oddly it is small @ only 10.5 " disc diameter
