Light weight flywheel AND clutch????

Greetings,

I am going to install a Fidanza aluminum flywheel and would like to install a high performance/light weight pressure plate as well.

2001 2RZ engine, otherwise stock 2wd (not a racer, just spirited street driving).

I see that there are competition twin plate units, but they are really pricey and I don't need/want to go that light for that cost ~$1500-2000.

Are there any lighter than stock weight pressure plates out there??

Any help appreciated,
thanks,
chris

 

Here is a pic of the Fidanza 7 pound flywheel. $399. from Summit Racing

Any recommendations for a good clutch, particularly a light weight/aluminum unit???

You might find something here. I don't know your application, or why you are all hot on uber light. Just use caution, as all the 'good things' about losing weight in this area will be countered by negative things.

Yes, it will spin up faster, but it will also spin down faster as well. It's sensitivity can be trickier to drive, especially in heavy traffic. You'll get used to it if you are the only driver, but if others need to drive the vehicle, they may freak a bit.

And contrary to popular opinion, it doesn't really make more power, it just lets the revs build faster.

Just speaking from experience here with lightweight stuff in lightweight sports cars with very revvy little engines.

 

Hi Bill,

Thanks for the link.

Here is a shot of my 85 Toyota xtracab engine ready to go into my work truck. This was a 12 pound steel billet from LC engineering. I just got rid of the truck, with 424,000 miles. The light wheel really helped perk up the engine. When I got into my "new" 2001 Coma, I was slightly underwhelmed with its slow revving, but that is fixable. If I could find a light pressure plate, that would help also.
My earlier Datsun work truck also got hot rodded and had a light wheel.
The second photo shows the flywheel from my old Ferrari. It went from 16 pounds down to 8. The pressure plate is about the same and it is a 3 liter 8 cylinder, so the difference isn't that great.
I have also put a light wheel in a speedster auto cross car, as well as had the flywheel machined from 28 pounds on my old 914 4 cyl hot rod. It also had an aluminum pressure plate and that thing would really rev and shift quickly.

All of these light flywheeled cars and trucks were a bit touchy leaving the line, (even in mild street driving), particularly, the 4 cylinder ones.

You are correct that lighter internal engine parts, (as well as lighter wheels, axles, tires and drive line components), don't increase the horsepower numbers at all. Measuring output on a dyno would yield exactly the same numbers, with either wheel.

BUT, lighter components will spin up faster, because less of the engines output has to be used to accelerate the mass, it is available sooner to accelerate the car or truck. It is kind of like two equally strong guys in a foot race, one wearing tennis shoes or track shoes and the other guy wearing heavy insulated work boots. Guess who gets to the finish line first.

Sorry, no pics of the speedster, Datsun, or 914 parts, but here is a shot of my all time favorite car, (lots of suspension and brake mods).
