I wouldn't touch the crank,
Just get it balanced.

When I get cranks done we only get them balance with clutch cover, crank pulley, flywheel all together, also getting them sized and polished at the same time.

We want to gain from weight from rolling parts because, my engine has all the equipments like hi comp. pistons 12.2 cr, ph 5 cams , newman valve springs, 1MM OVERSIZE 6000 SERIES COMPETITION VALVES, forget con rods, kent cams pulleys, at power itb, megane rs injectors, omex 600 ...
my tuner said that we couldt gain from ecu mapping any more we need mechanical change,
so last option is lighting rolling parts as i think

Lightening Advice - Dont do it.

What are you aiming to achieve?

[AXracing]

I would not recommend knife edge or lighten. One of the best bits about these engines are the cranks. They have brilliant counterbalancing that let these engines rev to high heaven. Any metal you take off odd are will just be detrimental. If your after throttle response have a look at a alloy of steel fly wheel.

What is your current power figure out of interest?

[axsaxoman]

If you really want ot get crank to lightest spec and still run your 8000rpm +
then buy a billet one----one made from a solid lump of better quality steel --
