NA: stock or lighten flywheel
 

which would be better for NA purposes, stock flywheel or lighten flywheel? i know that a lighten flywheel will give you a quicker response and make the rpms climb quicker, but i also heard for NA, you need the weight of the flywheel for torque?

Re:NA: stock or lighten flywheel
 

For N/A I would lighten it. For turbo you'll be taken care of on the top end by the turbo, so you keep the FW stock for the torque.

Get a machine shop to lighten your stock one.

i dont see how a FW can affect tourqe. (more if it's heavier?)

all it becomes is reciprocating mass. lighter the better IMO.

Re:NA: stock or lighten flywheel
 

The reciprocating weight of the flywheel helps keep the rotation of the motor going. From what I hear with a lightened flywheel/turbo/heavy clutch, when you let the clutch out it wants to grab the motor and "stop" it from spinning, which will make for a jumpy low end. That's what I hear anyway.

I have a stock lightened flywheel....it's a bit jumpy at low rpm's...below 3K.
It has no torque at all below 3K and climbs slow below 3K...above 3K it's a monster.
I think it's because I have it in a already low torque D15 block and the rest from a A6.

yah i've got a lightened flywheel in my a6..rev's so damn quick.

All i gotta do is jab the gas pedal and it jumps to like 4k instantly.

Re:NA: stock or lighten flywheel
 

i have a N/A car with a lightened flywheel but it doesnt run >:( so i have no idea

Re:NA: stock or lighten flywheel
 

Good investment. Get a factory one lightned to around 12-13 lbs.
