lightweight flywheel
just browsing the internet and saw this http://www.comptechusa.com/store/product409.html can anyone remind me what the purpose of the lightweight flywheel is and and what the postives and negatives are of having one thanks

on another note, I emailed Tilton (made the clutch and flywheel for the RTR tsx) about offering a product for us mainstream tsxers. They responded by saying that RTR bought way more flywheels than expected and they could give us a contact at RTR. The Tilton rep said RTR may sell their extra flywheels to anyone who wants it. It was a bit peculiar though that RTR said Tilton made a clutch and flywheel, yet Tilton only mentioned a flywheel. I'd be surprised if RTR opted to use a stock clutch for competition.

The last thing you want is a racing clutch on a street car. They're impossible to drive in stop and go traffic.
Lightweight flywheel can be a good mod but just don't underestimate how long it takes to instal. If you were going to do any clutch upgrades, that would be the time to do it.

you are going to remove the entire transmission to get to the flywheel. a person can't do it by themself, and its going to cost a lot to upgrade. like dan said, its optimal to swap them when you already need to be in there to replace the clutch.

i havent seen any clutches available for the tsx as for the moment are there any other applications that would work? i was jw b/c once a SC/TC comes out i would like to do everything at once ie new clutch,flywheel,SC or TC,etc.... although i know it will still be a while till before it is released ...thanks again

I haven't seen any clutches available yet either but I imagine once forced induction becomes more popular we'll start to see kits on the market. It is also quite possible that you could have a clutch adapted from another car.

The one thing to be careful of with a lighter flywheel is the idle speed. A car with a lighter flywheel will tend to idle at a higher RPM with a lighter flywheel. hope this helped.

Like JTso said, the whole reason cars have flywheels is to store the engine's rotational momentum to smooth out shifts and whatnot. A lightweight flywheel works both ways; easier to speed up, but since it stores less energy, between shifts the engine will lose more RPMs.
A bad thing with a VTEC car if you ask me. I bet if someone compared acceleration times between cars with light and regular flywheels, you would see that the car with the lightweight flywheel would be:
faster to 30
slower to 45
faster to 60
slower to 75
and so on..

I know that this is a really old thread, but just thought I would contribute my experience.
My previous car was a '97 Integra GSR. I had i/h/c/e and also UR pulleys and an Integra Type R flywheel. Two of my favorite mods were the lightweight UR pulleys which pulled harder from idle to redline and also the ITR flywheel.
I think where a lot of people become frustrated with flywheels is that most of the aftermarket flywheels out there focus their advertising on who has the lightest flywheel possible. IMO super light flywheels should be more for racing applications. The make the engine rev nice and fast and help with initial acceleration, but like stated can drop the rpms out of the optimal power band between shifts. Going "too light" so to speak is the problem.
A moderately lightened flywheel such as the GSR (18lbs stock) and the ITR (15lbs) stock (only 3lbs difference here) helped with acceleration in every gear due to faster revs and also didn't drop my rpms too much during shifts. 5th gear acceleration on the freeway was significantly improved as well often eliminating the need to down shift in certain passing situations unlike before the upgrade.
I'm sorry this is so long winded, but I think moderately lightened flywheels can provide more balance for daily drivers like us. Perhaps options like flywheels from the k20 RSX-S, the japanese Integra DC5R, or maybe the new Civic SI. Does anyone know the weight of the TSX fly vs the weights of these other cars? I don't even know if they could be installed properly, just throwing it out there for idea sake.

I agree. Having had a Fidanza flywheel in my 04 TSX, it was fantastic. I loved every aspect of it and it was about 10lbs lighter than stock. I did have to take my flywheel out because the clutch kit (ACT) decided to have a failure (mentioned in another thread), thus having to put in an Exedy application which required the flywheel to be replaced (basically an RSX Type-S application). So I still have my Fidanza, which simple needs the friction ring replaced available if someone were interested. I initiated the construction of it with Fidanza and again, it was absolutely one of my more favorite mods, but it wouldn't work with the Exedy clutch to do dimensional differences. It works with any TSX specific clutch application, thus keeping it available for use on stock clutches.
