Title: Light Flywheel V6
Post by: opelfreek on 12 March 2012, 21:06:38
Hey  :)

Wondering if anyone has replace flywheel on a x30xe, one from a different engine (xe / let / xev) to get one that is lighter than the original V6 flywheel (15kg)
  If so, what have you taken and what clutch did you spend?

Hey Serek !!

Sincerly

I think i'm getting on this one...
Does anybody know the length of the spacer?
I can make it and the dia's are easy, just need the length...
Also, What's the bolt pattern on our x30xe's? Looks like the c20xe has 8 bolt holes....

Got one in mine but was already fitted when I got the car now a bit worried as to when I need a new clutch they will fit the wrong parts

I would get the parts listed above and tell them to compare them to the old ones....
Or do the job yourself??? Not that hard....

Inner or outer diameter ?
Inner diameter is the same, that i found out yesterday when i try the c20xe flywheel on my X30XE engine/cranksaft  ;)

Is it a straight swap then? It was the outer that I was referring to....
I need to do something as my DM is buggered! Clank, clank....

Also, I'm guessing the point of this mod is faster engine response, better engine braking and maybe impoved fuel economy???

Just faster engine response, really. You might find slightly quicker acceleration in the lower gears, but the main reason to do it is to allow the engine revs to fall faster from the red line as you change up the gears, and for quicker response when "blipping" the throttle to match the revs on downshifts.

It won't affect engine braking or economy.

I was lead to believe that with a lighter mass of the flywheel, you gain engine braking???
Which I think is almost non existent on the Omega, well it is on mine anyway???

Silky smooth free revving equal balance 6 cyl makes it feel like that :)

MPGs may increase but not really noticably, just less turning mass on the engine etc, same as losing the air/con pump (no on)

Diameter would be the same, or the starter wouldnt work :)
