Lost a bit of weight .........just over 2kg ! Will post after next remap to see what it has done. Good news is it should cost less to post back.

[TurboTurkey]

What does it weigh originally ? (turbo or NA) Where did you have it done? did they drill or skim of both? interested to see the results

[VX-GT]

what is the new mass (weight)

[Baron Von Scubadaddy]

2 kg lighter than it was originally !!!! I'll pick them up today and take a picture and post it so we can see what has been done .

How much power will it have gained you?...........(snigger)

[Exmantaa]

I had my OEM flywheel lightened by a German tuner. Went from ~9.5 kg to about 5.8kg.

Milled, drilled and fine balanced:

How much difference did you notice?? Was idle affected much?

[chris_uk]

Mine was 9.5kg to 4.5kg Or something close Idle wasnt effected but it certainly revved up much quicker. Check my youtube channel for vids (vx220ukct)

Any down sides at all then ???

You have to think when pulling away, car no longer lurches forward regardless of revs when clutch released.

i found the revs dropped quicker when changing gear etc

[Sticky]

i found the revs dropped quicker when changing gear etc

and when backing off.

[The Batman]

mine drops seriously quick, good thing i learnt to heel and toe in the van

[chris_uk]

Yea the flywheel will reduce its speed rapidly as there is no weight to keep it rotating as long. Not a peoblem on the road but on a track the sudden weight transfer firward when lifting off may cause some issues if you dont learn to reduce the effect, toe and heeling for example.

I don't think you get any extra power do u ???????
Just gets the engine spinning up quicker
and also the car now weighs less.

[Baron Von Scubadaddy]

Couple of snaps of whats been done.No I didn't take a picture of what it looked like before.
I do know that it weighs less and it is now balanced and true.
Will post my feelings of this latest mod once rebuild is complete.

[chris_uk]

just looked at my video it was 9.5kg but the new one was 4.2kg

video 1 - idle


video 2 - through the revs pre s/c (160bhp)

It was a test based on you stating you'd post up after a remap

Lightening the engine's rotating past is a really good idea, makes the car feel a lot racier. However, you do have to be a bit careful as in mine I have lighter con-rods as well and as a result it is very hard for the MOT man to hold the revs steady to take an emissions reading. Just something to bear in mind.

[The Batman]

i got lightweight flywheel, not sure if conrods/pistons are lighter , all lightweight pulleys, balance shaft delete, balance chain delete, water pump delete revs like a motorbike hence the need to absolutely learn heel and toe but it definately makes alot of difference not alot of vibration at idle either which is suprising, cant say i had a problem with mot though maybe different for tubby cars
