Default Do i need my flywheel skimmed or not?

Im planning on upping the power on my car from standard 240bhp with a VF23 FMIC and Walbro fuel pump so expecting 300+ BHP with any luck.

Anyway my clutch is curretly fine although im expecting it probably won't be
after the power upgrade.
Im planning to fit an Exedy clutch before i do the upgrade to save me doing loads of work and then the clutch slipping.
Can i just fit the new clutch without getting the flywheel skimmed?

Get it skimmed. Its good practice if nothing else.
Would not want to take the box out again if there was any issues
It also means a little less weight

Wuz can do a good deal on clutch and skimmed fly balanced to match

Im no expert, but i wouldnt have though the flywheel would need skimming if theres no obvious scoring/high spots. If you do get it skimmed, make sure its by a reputable company so that its done properly AND balanced.

Personally, i would change to a new lightweight flywheel if funds allow.

What type of clutch fo you have? With Cerametallic clutches we recommend using a uprated/forged flywheel.

Cheers,

Bob

Thats not always the best way forward for a road car.

I have driven many scoobs with different weight fly wheels and I opted to run a skimmed oe flywheel.

YES you should ALWAYS SKIM a flywheel to give the new friction disc a chance to bed in onto a fresh surface. That's why so many peoplke on here say they have a new clutch fitted and it still judders. Because it didn't judder before [ unlikely ] doesn't mean it won't after a new clutch.

AND

NO you cannot fit a ceremetallic paddle clutch to a cast [ OE ] flywheel the material is too aggressive and the OE flywheel will be mullered within 1000 miles. You need a steel billet flywheel.

Clever guy - got it in one

Yep.

Steel billet flywheels can be a nightmare. MANY of the cheap ones do not have hardened starter ring teeth and you end up with dodgy starter issues in a few months - then you'll need another starter and a flywheel. Despite claims from the cheap flywheel sellers, try running a file across the teeth of whichever one you buy. If it slides across and does not make a mark then it is fine - if you can file it, send it back.

Nearly all steel flywheels I have seen, have the teeth for the starter cut into the steel. IE no separate ring gear - hence the lack of hardness. And also hence, when the teeth wear away, the whole wheel is scrap rather than just the ring gear.

Call me for a proper price on a proper one, that will not embarrass you or me a few months down the road.
