If it's not to much of a pain, pull the tranny and do a visual inspection.

 

Rocket,
What is your opinion on the new Tilton clutches and PPs. I noticed you have not listed them. I know they are expensive and the new product is relatively new, so you may not have seen one. But I have read articles that herald this new clutch as a great addition to powerful Hondas.

CLUTCH 101

HOW TO RECOMMEND A CLUTCH

This is a question I am asked very often, "Which clutch should I get?" I usually have 2 to 3 clutches in mind but since the clutch affects the way you interact with your car a clutch seller should try as best as possible to understand BOTH buyer and the buyers car. The general rule is the more hard core you are the more likely I recommend a puck disc. The more conservative you are I would recommend kelvar.

...more to come

 

Who make's a good segmented Kevlar disc?

Does a disc alone increase the torque capacity of the entire clutch?

How is a segmented kevlar disc differ from a straight kevlar? torque capacity?

 

Action has good segmented Kevlar discs like the one pictured in the earlier posts.

The reason for segmentd vs. full face Kevlar is that Kevlar needs more pressure to work properly.

Yes, torque holding capability can dramatically increase with different friction materials. It's measured by what engineers called coefficient of friction. The lower the coefficient of friction to more force is needed produce the same holding power.

Copper Ceramic has one of the highest (but tends to break up under heat). Kevlar actually also has high coefficient of friction almost approaching that if the sintered metallic pucks.

 

Tiltons seem nice but they are hard on your synchros. This is from 1st hand experience becuase I rebuilt 2 tranny's for a customer of mine that runs a Tilton.

My personal opinion on RPS is that Rob Smith does a good job of marketing. I've never got my hands on any of his clutches because not many people run them here in LA. Kinda makes you think doesn't it.

ACT makes really good pressure plates and clutchnet makes really good discs.... would it be a good combination to run an ACT pressure plate with a clutchnet disc for a 500hp daily driven honda?? I would like to keep the pedal feel as close to stock as possible with the engagement somewhat smooth.... What would u recommend i run? I cant find information on the Action Clutches.... I am getting mixed results on ACT and Clutchmasters...

 

The only bad thing that I've heard about ClutchMasters is the springs tend to pop out to easily. What if I never launch at high rpm (4k or lower), would you consider a CM stage 3 is a good clutch for daily driving? TIA.

 

Wow, what a perfect thread. This is exactly what I needed.

 

Doesn't matter, the springs in the disc can just get beat without hard launches. This is especially true with the lighter flywheels. Crank rotation has jerkiness to it and it kills the disc.

 

review of action clutch.

Action is basically the combo you propose. The reason why you can't find info is because Action is a small shop which never advertised and does many clutches for shops and some name brands. I am one of the main sources for advertising for Action.

However, this thread is not meant as plug for Action, it is meant as a Educational post, and I have tried my best to explain what I know about clutches without bias.

 

any review on clutch specialties? how come i've heard some brands are just the same clutch as others? is that weird? good post i needed this lesson. especially the part on material and construction of the disc.

What do you think of Exedy clutches? Because when I first got it in the mail, it look liked a basically stock unit? is it? From what it says on their website, its supposively able to handle up to like 300lbs of torque, and this is their organic unit..

 

That website is lying. It is a stock unit.

 

Those are good for about 180ft-lbs torque max.

 

Did you get the standard, or the "racing" organic ? I was under the impression that the standard one was OEM, and the racing was a bit more aggressive. I'm thinking of getting the racing organic soon, so I'd appreciate some more info

 

Exedy's racing pucks are not all that either. They have stock like sprung hubs.

 

I will have some words on Clutch Specialties.

 

Not the 3-puck ones, the solid disk organic ones. Supposedly 32% "capacity increase."

I'm looking for something pretty mild, but a little more aggressive than stock, and possibly complimented with a light flywheel (as I'm not FI, and not even bolt-on'ed yet )

 

Their clamping load figures are way low.

Pedal pressue stock is higher than this so clamping force is about 5 times this due to leverage. Clamping force is a multiple of pedal pressue due to leverage. Look at my diagram and you can see why.

 

How good are the Exedy pessure plate's though?
Mine said it was at 70% over stock.(212MM 90-90 civic/crx)
I was thinking of using my Exedy "racing" pressure plate with an Action Kevlar disc.

What do you think the limit's of that are?

I'm trying for 350HP, but I am not going to be doing much track driving. Will this setup work?

If you have a B-Series motor it's cheaper to just get a whole Action kit. I'll post more Clutch 101 on how Action pressure plates are made.

 

The engine is a ZC.

Can't wait for the pressure plate section!!

 

It will be best for you to get the 90+ flywheel and use the 212mm clutches. ZC clutches are too small for that kind of power.
