It was believed that using a UR crank pully in combination with the lightweight Comptech flywheel removed too much dampening for the stock pressure plate to handle.

I've been running the Comptech Flywheel and the stock crank pulley for around 33K miles with no issues. ThinJim has been using the Comptech flywheel and is putting down around 460whp without blowing up the pressure plate. It slips a bit with that much power but he's at an extreme level.

 

sorry to hear that allmotor! I have the comptech clutch/flywheel set installed in my 03 cl-s too. Nice difference...love the performance! but like everyone else I would have never expected something like that from a comptech product.

^next time, check the date of the thread before trying to offer condolences.

 

At least Ram will know he's missed

 

hmm, so no need for the UR crank pulley with this setup eh?

what about with the high power clutch setup that is being offered now that ive seen in another thread?

 

Shit, I have the lightweight flywheel being delivered already, and I have the UR crank pulley installed already. I guess I'll find out the hard way...

 

yes maam! didnt think it would matter

 

Both have benefits but my feeling is that you do one or the other. Doing the flywheel is much more costly but does also offer driveablity enhancement.

 

We'll keep our fingers crossed

Based upon your setup, we'll find out for sure if it's the combination that makes the pressure plate fail. Are you using the stock friction disk in your setup? If so, you're really going to punish the clutch. At least the Comptech setup was using a sprung hub disk. By you reducing the curb weight of your car, you'll make the clutch work a bit less which may help.

You're a prime candidate for an upgraded pressure plate combo of some type - especially with the power you're putting down.

 

Shit! now I find this. My CT clutch and flywheel didnt last long at all, and the pressure plate exploded. I've had a spec stage 2 in for about 10,000 miles and its starting to sound like the pressure plate is falling apart again, little klinks here and there. OF COURSE i also have the UR pulley I'll swap it out asap. Hope its not too late-

 

Good thing this thread was brought back up. Members might learn something or avoid costly repairs with this info.

 

My comptech flywheel, along with crank sensor just ate shit!!! it happened 3 weeks after I got my unorthodox pulley set. This sucks! that was a waste of 1,500 bucks! I COULD OF BOUGHT A SUPERCHARGER!!!F@#K $ ^%* %(#

Sorry to hear that. How long had you run your Comptech Flywheel before you added the UR Pulleys?

I've been running the Comptech Flywheel with SC for around 38K miles. I've had seal leaks but no problems related to the flywheel or pressure plate.

 

I just noticed that you read and posted in this thread back in March 2007. Why did you put the UR Pulleys on after reading this thread?

 

i ordered a ur flywheel, will the ur crank pulley have any effect? Should i take out the pulley or will it be okay?

 

The whole point of this thread is to tell you to avoid using the stock clutch kit if possible, but more importantly:

DO NOT USE THE UR CRANK PULLEY AND ALUMINUM FLYWHEEL TOGETHER< THERE IS NOT ENOUGH DAMPENING AND AS A RESULT THE PRESSURE PLATE GOES TO SHIT.

Not sure if an aftermarket clutch kit would be more resiliant and allow you to do both however.

You can try calling them and asking but they probably wont know, I think I called them onthis when the UR flywheel came out and they could not say. However the UR flywheel is only 2-3lbs heavier and the same thing will probably happen to your car if you try running both.

 

i need to find out b/c i dont need my car in the shop for any more problems

 

bc im not sc'd, will this still affect me?

 

if i had to run one, which one (pulley or flywheel) would be preferrable?

 

Is there any way to run both (upgrade pressure plate)?

 

'The only decent company that makes a clutch kit for our cars as of now is c.l.u.t.c.h.m.a.s.t.e.r.s. just get there flywheel/clutch kit combo, wer're trying to get a group buy going on it on v.6.p.n.et. Its pricey though about $700 for the flywheel and $650 for the clutch kit, we're trying to get them to drop the prices.

You can try and be the first person and try the pulley and flywheel together with their clutch kit. You could try purchasing their clutch kit and using the UR flywheel that you got.

If I had to pick one and money wasn't really an option it would be the flywheel since your removing more then twice as much weight. 17lbs with the UR flywheel, and 19-20 with the other ones. Versus the 7-8 with the crank pulley.

 

I don't think you can use the c.l.u.t.c.h.m.a.s.t.e.r.s. pressure plate on the UR flywheel. It's specifically matched to their flywheel. Both were designed as a package.

And I would agree. Between the two, go with the Flywheel. In addition to the lighter weight, the position of the weight is important. The weight reduction on the outer edge of the flywheel is more productive than the weight reduction on the outer edge of a crank pulley since the diameter of the flywheel is greater. Same concept as heavy 19" wheels slowing down acceleration. The additional benefit is you get a single mass flywheel and better/easier clutch engagement. It drives like a clutch should.

 

Yeah i've been thinking the same thing about there clutch kits since even with their stuff it requires some modifications or so some have said.

What is this better clutch engagement that you speak of?

 

i talked to mr.steve and he said the comptech clutch would be compatible. I think I might get the one selling in the black market

 

Don't, its crap, and which PP would you use? Your stock one?
We're assuming it would be compatible if everyone built there stuff right, usually it comes down to the splines on the PP needing some more clearance or something along those lines (refering to the CM kit).

Just saying if you have any plans for FI dont get that clutch.

 

If you're talking about the item littletroung is selling, it's just the friction disk. A full clutch kit is made up of a flywheel, friction disk, pressure plate. This Comptech Friction disk was intended to be used with their flywheel and a stock pressure plate. I would imagine that it could also be used with the UR flywheel too. It won't work with the stock flywheel.

SPEC is the only other company that I know of selling a pressure plate that will work with the lightweight flywheel.

I think ThinJim was selling a used Comptech Flywheel. PM him and see if he still has it. I personally like mine and it's holding up fine. BTW - $200 for the friction disk is a good price.

 

If he is only looking for added performance from the lightweight UR flywheel he doesn't need to worry about an upgraded pressure plate or a stronger clutch.

You can not use the stock clutch with the UR Flywheel since you'll lose so much mass the driveability would severely suffer. You need a sprung clutch (like the Comptech piece).

 

Well considering the friction disk is equivalent to that of the OEM unit you can get the OEM unit for $230 disk and pressure plate. Also you can't get a replacement pressure plate (stock) by itself, it comes as a kit, so its either or.

 

If all he's looking for is a stock friction disk, I've got two brand new Acura OEM units laying around.

 

i ordered the comptech clutch from littletroung so hopefully everything works out

 

i put 7000 miles on my clutch kit, still hook up well

SPEC is the same as the OEM PP with blue paint, so NO don't buy that! You can not use lighten FW with lighten crank pulley without upgrading the PP. it's either the FW or the crank pulley...

 

God luck, just go with the crank pulley then.

 

so, as of right now i have the comptech friction disk, the UR flywheel, and my old oem pp. Should I replace the pressure plate with a new oem one or just keep my old one?

 

oh, so i guess i'll have to keep my stock pp for now then

 

yes I was aware but I prayed to the vtec gods that after installing my pulleys it wont happen to me, I thought it was just his car. I had my pulleys for about 10 months before installing my pulleys. I do use my CL as a daily car and I am very agressive with it, especially during traffic! When the mechanic took the transmition apart, it turns out my clutch was gone already and it would of been a matter of time until my clutch ate shit. Pieces of the pressure plate were broken, the clutch was worn down to the bearings, and the teeth were the c/sensor meets were bent nasty style. I'm switching back to stock clutch and flywheel and keeping my pulleys, I'll let you guys know if anything happens. I'm going to try to get a digital camera and hook u guyz up with picz.

I would suggest you get a new one due to the nature of the flywheel. No sense in your pp going out just because it was a used older unit when the new one probably could have taken it.

 

and get a new throw out bearing too while you're at it.

 

Seriously, I mean why take the chance? that would be like me reusing the original timing belt that came on the junkyard motor that I used for my swap. Not worth the savings. Anyway when you get it done we should meet up so I can see how it is.

I've driven a few setups, but im just forgetful I guess. I want to see how the clutch engagement compares.
