Jim,

I had the stock flywheel lightened and balance when I was having the engine
rebuilt and I was told that only about 4 pounds was taken off. It definitely
changed the car's character if that's what you are looking for. And from
what I was told, that's as much as the machine shop felt safe taking off.

I don't know what velocity does to the flywheel or how light it is, I have an
eip lightened flywheel which has 6lb's removed. The weight is taken from the
outermost portion and back side of the flywheel, this greatly reduces the
energy it takes to accelerate the mass. It also is fully resurfaced, which is
$50 by itself. Since I did it at the same time as the eip/centerforce, it
really only cost me $100. 

You definitely can notice a difference when you initially stomp the throttle.
The response from the engine is much more immediate. I don't know how much, if
any hp you would gain, maybe some torque. 

I like the flywheel and the improved response a lot, but I would rather have
the eip aluminum flywheel. It is much lighter than the stock lightened unit.
It wasn't available when I did mine but I would definitely choose the aluminum
version now. I held the flywheel side by side with a stock version, I don't
know what it weighs, but it's light as hell, especially compared to stock. One
other trick thing about the alu. unit is that it has a replaceable steel disc
that contacts the clutch disc. This is replaced when you do a new clutch
rather than having to have your flywheel machined.  

Peace,
Mike-O

I picked up my car from the dealer yesterday. They rebuilt my tranny and 
put in a few parts I supplied while it was apart. They replaced the 
second gear synchro and all the bearings and a bunch of other misc 
parts. I had them put in a Quaife diff, Velocity lightened flywheel, AP 
racing clutch (thanks Jim Chu), and a 3.67 final drive.
  WELL......Not much of a difference right away but after a day of 
driving......WOOHOO!!  The clutch chatters a bit but it is getting 
better. The Quaife, what can I say other than it should be O.E.- 
-superb! The flywheel and final drive help to propell me ahead a little 
quicker. I have noticed no ill effects from the flywheel, the idle is 
fine and no problems in the launch. 
Total cost for those of you wondering is as follows:
Quaife- ended up costing me ~$900.
Flywheel- $150
R&P- $275 used and I got an extra stock diff
Clutch- $425
misc pieces- ~$50
Parts and labor at the dealer- $1440
totaling--$3240 (ouch)

I had the Velocity lightened flywheel in my old G60
GTI.  It made a dramatic difference!  I loved it!  I
never had a problem with the revs dropping so fast
that the car stalled.  I really wouldn't worry about
it.

The engine was so willing to rev, it was great!

i'm going to replace the timing chain guides in my 93
C this spring and will be installing a velocity
lightened flywheel, along with a new clutch and the
bolt kit in the tranny.  I highly recommend you do the
bolt kit when you do the clutch/flywheel.  Nothing
like a fragged tranny to ruin your day.

Well I have over 70,000 Miles on my Lightened Flywheel, and must say the 
only time I really noticed a difference was with the SACHS Aluminum pressure 
plate combo. It drives fine, idles fair w / AC on(I have 268's). I never 
really noticed a negative. But with a normal clutch/pressure plate combo, I 
didn't notice that big of a difference. So my recommendation is don't tear 
it apart just for that, but do it when your up for a clutch replacement.

Oh yeah.... I'm on my 7th clutch... Maybe its time to learn to drive:)

When I changed my clutch in the spring I had the stock flywheel shaved down
to ~12lbs...not as good as the aftermarket billet flywheels, but a third of
the cost.  Performance wise it's a good upgrade.  Car revs up quicker,
easier.  Not worth the labour cost however, unless you are already going in
there to change the clutch or work on the tranny.

Faster revving both up and down the powerband.  No
real drawbacks, but not enough of a difference to do
unless you're pulling the tranny to do a clutch or
something else...

I had a lightened flywheel on my 2.0L (7lbs).  I experienced a quicker
revving engine.  The engine also lost RPM faster once the clutch is
depressed.  Rush hour traffic took a little extra clutch slipping and the
engine vibrations were slightly more noticeable,  but no other downside were
noted.  I will do a lightened flywheel on my GTi-VR6 when I replace the
clutch.
