I am interested in this little piece of metal and I was wondering, for those who have it:

1. how you like it
2. how much it cost you

Disclaimer in advance for all the post ******: I did a search, geniuses. Nothing came up, Im going to check the archives now.

 

there's also an 8-lb chromoly one apparently...anyone got either of these? I remember hearing good things about the construction.

Chrome moly is bad and heavy.
Aluminum is better and lighter.
Do a search.

 

Chrome moly doesn't warp aluminum does

 

****

 

How much would I have to worry about warping? My setup is pretty much stock and it will stay that way.

 

check w/ Mike K, he has one and he likes it...

I'm sure he got a deal on it, being that he sells them and all

 

Interestingly enough, as much as he posts here, he's not that easy to get ahold of. I feel like a dick calling him at work, and his answers tend to be one-word, or grunts. I will call him again though...

 

my friend has one in his type R and it reves nicley, the revs drop down REALLy fast, but revmatchin and heel-toe is VERY much improved, its just so willing to rev its fun. highly recommended. !

 

That is the biggest load of BS.
Keep that crap to yourself.

 

hahahahahaha ohhh I love it

 

How much $$ separates the prices of the two Comptech flywheels?

Yeah you gotta love Sakai's responses...as long as you're not on the receiving end of the insults...he always tells me "Use your common sense" and "You don't listen, do you?"

 

I have the Comptech aluminum and i must say it is a nice piece. I payed a little over $400 for it. Worth it in my book. It was the first modification i did to my transmission and it felt really good. Much quicker revving!!!

Problems that I have heard with aluminum flywheels warping has to do with the physical properties of the piece.
An aluminum flywheel has a steel friction surface mounted to it with some sort of fastening device, bolts, screws, whatever. This will allow you to only replace this part if it gets gouges in it or warps. The problem lies in the thermal rate of expansion for the dissimilar parts. When the flywheel, bolts and steel friction surface are heated and cooled, they expand and contract at different rates. After a while this could lead to the friction surface not sitting absolutely flat. I'm not sure how long this will take or if it will ever happen with your particular flywheel. I just feel that it is one more thing to go bad in the car.
I would much rather have the slightly heavier one made out of one material. You will have more consistent performance from it. Also there are no bolts to ever loosen. It's just a little more piece of mind.
Also, Don't Toda And Spoon make one piece chromoly flywheels? I think they are about the same weight as the Comptech piece also. Makes me wonder why all of the sudden they introduced this piece when they have had the aluminum one for quite a while.

Just my opinion, and you all know what those are like.....

These warping aluminum theories are getting tiresome. All warping reports that I have heard are years old and are third or fourth hand reports and none involves the Comptech flywheel.

Comptech most likely introduced a chromoly flywheel because these silly warping stories stopped people from buying their aluminum one.

I had one in my R. It was one of the better upgrades I did. One nice thing about the aluminum flywheel id that it's only $75 to have the frictoin surface replced and the whole thing re-balanced, and the clutch step distance remains the same. On any single piece flywheel, as soon as you have to re-surface it, you'll start to loose clamping force from the increased travel.

Mike

 

I've so been waiting to use this...

 

Just get a clutchmasters. 1/2 a pound is not worth $125 IMO.

 

For those of you who are using the Comptech 6.75-lb flywheel:
How does your car idle compared to stock? The purpose of a flywheel is to keep the motor running smoothly (and make the car easier to drive since the car will not stall as easily). A 7+ pound flywheel reduction is a major drop in weight. Any negative aspects that we should know about?

 

Funny funny but when I've seen one and you haven't, how can you say that?????

Have you even seen a warped comptech flywheel??? well last time a brought my car into the dealership I did. I don't know what it was from but it wasa done deal.

Before you flame me, YOU'd better know what you talking about too, you bitch

 

haha...Hooptie doesn't look quite as stupid now...

2-piece Aluminum still sounds like a good choice though

 

I am assuming you are talking to me.

I just wanted to post that picture; I honestly don't care whether you are right or not. And it's not worth my time trying to figure it out

 

It's basically a .75lb lighter version of the clutchmaster which is cheaper ($279) Fidanza makes them for both companies. The Comptech chromoly one is stronger and a little heavier. The aluminum flywheels have the replaceable friction surface also. The car definitely revs faster with a lighter flywheel, and decellerates faster also.

We sell all 3 of them at Diablo. $425 plus shipping for the comptech aluminum, $392 for the comptech chromoly. Call 866-Diablo-1 mon-sat 10am-7pm Pacific time to order. Ask for Mike B.
We are authorized Comptech dealers.

 

You are correct, I asked them why they started producing the Chromoly flywheel and they stated that the market demanded a Chromoly flywheel as most people don't do the research and are afraid of the Al flywheel...in short to make money they produced a product that will sell in today's market, while keeping the Al flywheel available to those that prefer the lighter flywheel and don't put creadence in the "It's made out of Al, it's going to warp." bs...Realtime purchased 6 flywheels from Comptech over 2 race seasons ago, and they have yet to ruin one, or have to order replacement parts for them.

I asked the person that is in charge of R&D for Comptech and asked him which one he would use...and he stated that he was putting the Al flywheel into his own car within the month.

Mike, are you sure about that...Comptech told me that everything other than the ring gear(which was sourced from the OEM manufacturer) everything for the flywheel was produced in house by Comptech at their rather elaborate machine shop.
