if i go from stock to stage 1 clutch and a light weight flywheel, will my 0-60 times and 1/4 be faster by a few knocks? and by how much you think?

qcktegls

it all depends on your shifting. if you suck at shifting then u could run slower times.

No your car will not be faster.

It does allow the engine to rev more freely, which is good for downshifting around autox and road courses.

I have a Clutchmasters Stage 1 clutch and 7.5 lb flywheel in my car, had it for over 50K miles now, highly recommended.

Well, strictly speaking and all other things being equal, it will be. BUT NOT MUCH.

It is the rotational equivalent of removing weight from your car. Since the flywheel has to be accelerated in order to accelerate your car, if you reduce the torque needed to accelerate the flywheel then there is more torque "free" to accelerate the car.

But again, there will not be a significant difference, and it would be hard to verify through testing.

As Patrick says, the primary benefit is seen when the clutch is disengaged and free to rev, such as when rev-matching while downshifting.

If you're concerned with mainly 0-60 and 1/4 times then a super light flywheel might not be your best bet, autoX and road racing on the other hand could take full advantage of a 7.5 or something.

Ditto to what everyone said, prolly best used for autox and road racing.

doesn't a lightened fly wheel hinder idle? (Just a question, it wasn't a consistent problem in the car's I've driven with it in)

if u put a stage 1 then its kind of good because it can give u better shift, it takes more heat and it lasts longer but depending how many horsepower is depending what stage u pick

redINTEGRAdriver

what would a stage 1 clutch do different then a stock? is it worth the extra money?

u always say this...LOL when the engine is spinning, it has to devote some power/energy to spinning the 20lb stock flywheel or whatever, taking power away that would go to the wheels... if u have a 7lb flywheel, ur car wont make more power, but less actual hp will be put into rotating the lighter flywheel..allowing more to go to the ground....... phsyics....it pwnz

i believe u loose torque with a lighter flywheel... but great on the freeway if u're cheap like me and don't autoX

riceball777

this is common sense people
if you take weight out of the rotation assembly the engine will loose less hp from the rotation assemble and more hp will get to the wheels, so therefore there should be more whp
lighter flywheel, lighter pistons, and rods, knife edge crank, smaller geared trannie, smaller brake rotors, lighter wheels, should all free up more hp tp the wheels

Nononono. This misconception is one of my pet peeves. Don't take this personally, but:

THE FLYWHEEL DOES NOT PRODUCE WORK, THUS YOU CANNOT "LOSE TORQUE" WITH A LIGHTER FLYWHEEL.

Your engine produces torque. Torque is a function of combustion pressures through the geometry of the cylinder and the crankshaft. The flywheel has no impact on this.

However - just like it takes torque to accelerate your car, it takes torque to accelerate your flywheel. SO - the less torque required to accelerate your flywheel, the more can be "used" to accelerate the vehicle, resulting in faster vehicle acceleration.

The reason some people say you "lose torque" is this: When you launch from a standstill, you typically rev the engine to a certain speed as you're engaging the clutch. When the flywheel is rotating at a given speed, it possesses energy that is proportional to its mass - the heavier the F/W, the more the energy. Thus, it takes more torque to slow down the heavier flywheel, and the heavier flywheel will launch the car "easier" than the light one.

That being said - I went from a stock f/w in my GSR to a Fidanza unit that weighs like 7 lbs... And I barely noticed the difference in launch quality.

allenp &lt;-------What he said!

mrDFWmechanic

yup what /\ said

Nekekami

in terms of 1/4 mile times you'll probly get hurt. Your car will rev faster and have free torque, but every time you let the clutch out it will also DROP REVS faster. which means that shifting at redline normlly would probly keep you inside the powerband, with the lighter flywheel the motor will slow down faster and everytime you shift you 'll end up lower in the powerband than stock, possibly casuing you to bog down and lose time till you motor gets back to its powerband. Roadracing it rules though for heel toe shifting.
To restate what was said above, on a 1/4 mile its a minimal difference and probly not one worth the green, if you do autoX however, its a pretty good investment

rough_draft

with a lightweight flywheel the revs will go uip and down quicker, so if ur a shitty shifter the rpms are gonna drop more

only for a granny shifter...
i have an ACT prolight (~8lbs?) and the revs don't drop as fast as you make it seem....you still have ample time to get it into gear before it drops too much.

I found out that the real big, big deal race cars actually use a heavier flywheel when i was looking up the same thing. It has made me reconsider buying a lighterweight one, i'd rather just drop some weight off my stock one and get it balanced. But I was told that it comes down to what type of a set up you are using (street, drag, or track) and how high you plan on revving, its more related to that stuff then just saying one or the other is best.

NathanMorris

I'd just stick to the stock one unless you know how to shift well. That, and the money spent on it, could actually be used for a lot of things other than that that'll probably help you more at this point in your build.

yup. the revs don't drop that bad. it can bog a little, but you get used to it real quick. i have the prolite, too. 8.8 lbs.

boost. the heavier flywheel will keep the turbo spooled better... and when u have 1100+hp u can spare some hp for a 20-30lb flywheel.

FireMedic

I have a streetlite flywheel (12lbs?) and i can hardly notice the revs drop any faster... I notice, but only cause i'm concious of it.

The Poopsmith

you'll be losing aobut 10lbs from the car depending on what flywheel you get, stock GSR is around 18lbs. so you'll be .01 seconds faster
