just wondering what everyone is running as far as lightweight flywheels and what brand clutches is better

heres what i might get
one piece chrome moly 9.2 lbs flywheel (supposedly made by JUN)
comp clutch 6 puck disk
and comp +60% clamping torque pressure plate?

 

noone uses an aftermarket clutch or flywheel?

 

one last time... what clutches have you guys had the best luck out of?
and with a light weight flywheel do you use the factory counter weight?

 

ive heard from some ppl that light weight flywheels reduce torque? idk tho for sure

 

i know that becuase of rotating mass but rotaries dont have low end torque anyway

 

This is what I'm running...

even tho the flywheel is now half the weight of the original... the RPM doesn't feel much diff to me... at idle anyway... i'm yet to drive it so i dunno what it's like under load...

 

I use a ACT streetlite, don't remember how light it is off the top of my head, with a SS/HD clutch/PP. Its fine on the street as long as you know how to drive stick.

Lets clear some things up here about flywheels:

Flywheels do not make you gain or lose torque. Flywheels by definition STORE ENERGY. The "lack of torque" feeling associated with light flywheels is actually a lack of ENERGY. On a stock car, the flywheel "stores" energy in the form of rotational inertia, and transfers that rotational inertia to the rest of the driveline when the clutch is let out. This energy "spools up" (I know that isn't the technical term for it, but it makes it easier to understand) the transmission and driveshaft and axles which allows the power from the engine to just turn the wheels. A light flywheels stores less energy, and theremore more of the engine's energy is used to "spool" the driveline. This is why cars with light flywheels can feel sluggish off the line and a heavier flywheel is preferred for drag racing.

Now for the pros of a light flywheel. While a heavy flywheel can help off the line, once everything is moving, that flywheel is just a dead weight that the engine has to spin faster in order to rev higher. A lighter flywheel uses less of the engines energy to spin up with the rest of the engine, and therefore allows the engine to rev more quickly in the same way that lighter rotors or valvetrain components do.

ENERGY GUYS! ENERGY!

 

I'm running an 8.5 lb Fidanza flywheel and a "Stage 2" Competition Clutch and pressure plate combination in my TII swapped s4 NA. I haven't driven the car yet, but if you want to keep in touch for another month or so I'll be glad to let you know how it feels and my opinion.

plz do

 

Im running OS GIKEN Twin disc aftermarked clutch(this wont slip!). I know it aint got a lightned flywheel.
How noticable is it with a lightned one? Spiining the drivline is alot of "weight" anyway so i dont really see have removing 10LBS on the flywheel help.. Other than when you free revving..

 

If you use a lightened flywheel, you will need a counterweight from your years auto-tranny version.. But anyways Ive had good luck with a lightweight steel flywheel (aluminums havnt worked out to good for me on my TII for driveability purposes). My last setup was just a stock pressure plate and a ACT 6 puck unsprung clutch.. Clutch wasnt to stiff for driveability but it grabbed VERY nice..
