as a percentage base per displacement 360hp is a good way from a full 400hp in a honda on pump gas. 400hp is still a lot for any 4 cyl, even a race engine that's an impressive number, ok maybe not if you are an F1 derived AER and own a Lola.
Yes, yes, I'm sure someone could find me a dyno graph of a turbo Civic with a hair dryer turbo pulling some insane peak number....
Even with an LSD 400hp on a FWD car is a scary sounding. Unless maybe you could program the ECU/PCM to limit the sucker in the lower gears to a much lower boost level keeping well below 300hp and only use the full power on the top end. limiting the boost might also help save a so called streetable clutch kit too.
..and with the comptech flywheel being a steel unit you won't need the friction disc, you just resurface that flywheel.

Okay, I just got some tenative information from my contact at Fidanza:
-It should fall between 8.5 to 9.5 pounds
-Replaceable friction plate 1045 steel with high carbon content
-Replaceable ring gear
-6061 T6 aluminum
-Military grade fasteners
-Priced lower than Comptech's flywheel ($399 MSRP)
-It should fall between 8.5 to 9.5 pounds
-Replaceable friction plate 1045 steel with high carbon content
-Replaceable ring gear
-6061 T6 aluminum
-Military grade fasteners
-Priced lower than Comptech's flywheel ($399 MSRP)

High carbon content would be SAE 1090, 52100, or ductile iron. You are friends with 3 materials engineers and you work for a major engineering company, you'd think it would rub off a bit :P Just joking.

After years of engineering military grade still has no definable term without a spec. But it sure does sound cool doesn't it.
None-the-less it has be better then the cast lump rusting away behind the engine from Honda. What should scare you, are the bolt holding the pressure plate on military grade? It spins faster and is a lot heavier then the friction disc.
Thanks for the update though.

so, given MrChad's comments, how does the fidanza product compare to comptech's?
fyi - comptech:
* Lightweight Chromoly-Steel One-Piece Flywheel
* Heat-Treated so re-surfacing will not affect durability
* Weight: 10.5 lbs. (5lbs. lighter than factory flywheel)
* Application: 04-07 Acura TSX
* Installation time: 9 hours +/-
fyi - comptech:

* Heat-Treated so re-surfacing will not affect durability
* Weight: 10.5 lbs. (5lbs. lighter than factory flywheel)

As for the comments on the Comptech wheel. Chrome-moly steel is most likely something in the 4140 family, a very heat treat friendly grade of steel.
The Comptech wheel looks to be cast (billet machined is the other option likely here, it may even be forged but that would be surprising). The Comptech wheel will work fine, but it's only going to have a finite service life (the same as an OEM unit) maybe 2-3 clutches because of how you resurface the wheel. I really like the Comptech design, very close to OEM; but lighter. If you have one, keep it, if you need one now and can find one go for it. But it is pricier.
The Fidanza wheel appears (at least my Accord unit) to be made of billet Aluminum, which is very economic to produce vs. special casting w/ machine work. The replaceable friction disc also means you can likely replace the disc forever never ever needing a new wheel, regardless of the number of clutches you go through.
The kicker is, do you really expect to keep this car 400,000mi and 3-4 clutches down the road? I say likely not for most of us.
Once in the car I doubt you could tell these designs apart, and that's all that matters.

Back in the day, yes I'm kinda old, I would have never bought a two piece flywheel. Reason being, the friction plate is attached by screws, and is a different material than the disc. With 1000's of heat expansion and contraction cycles, I was always afraid the screws would eventually fail to hold and bam! there goes the flywheel and any thing in it's way. That is why I always had cro-moly flywheels (Toda Racing).
As I have aged, I have discovered that although the theory is sound, I haven't seen any two piece flywheels fail, and I have been watching.
So it's very cool Fidanza is making a light flywheel for the TSX, and everything I have ever seen of them over the last decade + is great quality and awesome performance, plus they have always been fairly priced.

And I dont why you guys are waiting for a "TSX" flywheel when the market offers a zillion flywheels for the RSX that will bolt right up. ![Thumbs Up](https://acurazine.com/forums/images/smilies/thumbsup.gif)
![Thumbs Up](https://acurazine.com/forums/images/smilies/thumbsup.gif)
I'm going to check to see if the 05 got a lighter weight flywheel now.
EDIT: Just checked part numbers and they are the same for 04-07 model years. I shipped the box to Fidanza and it weighed in at 19.15lbs. Honda Parts catalog puts the weight at 8.255kg, so that translates in 18.2lbs (I personally recorded a 20lbs on my scale). Now either FedEx's scales are wrong or your scale was. I'll have to ask Fidanza to weight it as a 3rd one.

EDIT: Got a response back from Fidanza and here is what I was told:
-Engagement from the engine mount to the ring gear is different.
-The step from the clutch to the friction plate is different.
Additionally
-TSX oem flywheel weighed in at 18.45 lbs. on our scale.

Alright guys I got some info from Fidanza. Here is some info on the flywheel. It has been designed and it has to be put into production. I am working on prices and production now. I will post up a GB to get some special AZ pricing going.
6061 T6 Aluminum
1045 steel friction plate
1050 steel and heat treated ring gear
Weight: 8 lbs
I need to get a list of people who are interested and ready to buy. The more I get the lower the price will go but I have to gauge interest. Please post ASAP b/c I want to schedule a production run.

FYI, my contact at Fidanza said, the more interest/orders, the faster the flywheel will be sent to production.

As an FYI for anyone looking to purchase the Fidanza unit. I just had the F22/23-H22/23 model installed in my '00 Accord coupe.
Install went without a hitch so the shop says, no drilling or anything special needed, a true direct bolt on. I also confirmed this by purchasing all new bolts prior to the install from Honda.
I had the clutch kit and flywheel balance checked at a local shop, the flywheel was totally true so you shouldn't need to balance the K24 units.
Even with dropping some 12lbs.+ the car is totally easy to drive. I've only had it for about a week now and have only driven the car a few times as yet. It's not my daily ride but everything seems ok.
As far as the clutch flywheel kit goes.
The biggest problem I had was that Honda wouldn't do the install so I had to find a local shop for the job. Just over $450 for labor on this job.

Just an update on timeline... My contact at Fidanza said the flywheel will be in production soon and estimating that I'll have a flywheel on my doorstep before the end of June.
