Does anyone out there have it? How much does it of a difference does it make?

 

a lot, and i dont have it

 

a lightened fly wheel maked your engine rev to redline faster, making it harder to drive in traffic.

 

which useing a bit a logic means many things, while it wont add horsepower to the engine it will lighten the rotational mass, ie freeing up more power to the wheels, it will also make it alot easyer to heel and toe when entering corners and rev matching. Although i dont have it it is on my 'wanna get' list so when my clutch goes i will do both at once!!

 

Basically correct. The rotating mass is less therefore, engine revs faster period. Remember you are not reaching max power etc until you are in the rpms where engine is most powerful. The sooner you get to that RPM the better. I have light flywheels in every car I own. FYI.

ROAD/RACE

 

Why is this? Sorry I'm a newb. Can someone please explain?
I've searched for this but can't find anything

 

if youre in traffic and your car revs up fast, if you arent used to it, the car is gonan jerk and if youre having fun, youll get some tire chirp if you let that clutch out.

 

the flywheel is officially on my neverending wish list.

 

i hear that, "hard to drive in traffic" is not going to dissuade me, a good enough driver can handle it, and with practice, im sure anyone can handle it, good or not!!!

 

i'm not that worried about the hard way to go in traffic either, i cant imagine its that bad and you'd get used to it.

 

I'm planning on getting new clutch + flywheel this summer... I'll let you guys know.

 

It is not too hard to drive. You will be used to it in a couple days.

ROAD/RACE

 

it's called knowing how to drive.....the car revs faster...a lot faster than stock, but it's not like revving a Suzuki GSX-R 1000...you can control it....just don't gas it as much.

i drove an OZ with intake/exhaust and flywheel, and it felt about as strong as a normal lancer with intake/header/exhaust. its very noticable

 

Its not like our cars rev THAT fast anyway
lol, I'm sure it'll be fine

 

Inertia is directly proportional to mass. I=1/2mr^2 I=inertia(kgXmXrad/sec) m=mass(kg) r=radius(meters(m)) and kinetic energy is 1/2Iw^2 where w=radians per second (1rpm is 2pie radians per min).

put simply, the more mass, the more inertia, and the more kinetic energy. The more energy the flywheel has the more friction it takes to slow down. Since friction in the engine is relatively constant if you make the flywheel lighter it will slow down much faster. Since this is true, it will take the engine much less energy to spin the flywheel faster.

The main reason this doesn't create additional HP on the dyno is because the difference in mass is in the drivetrain on the engine side and much more power is lost due to the moving parts in the tranny. When the clutch is depressed the transmission is not connected and therefore the difference in mass is much greater from stock to aftermarket, which is why everyone has told you the car will rev much faster. Get it?

It feels good to finally use the 600+$ in Physics classes I took in college
