I have to say something I'm afraid, I wouldn't risk that crank in an engine. It may have overall end to end balance, but the internal balance and counter-weighting are going to be way off, so the odds on failure are high.

I would of just got the standard crack, balance, and polished, checked for ovality. These cranks are very good standard cranks. But Looks like it going to be a good biuld! Good luck with it.

I've spent a long time working on VAG motors in the past, especially the 1.8t and 12v vr6, and never had issues with working on stock cranks
looking around at a few french builders, some do it and some don't seems to be a french thing lol

I know people do it. But I took my crank to these people who looked at it and said to leave these cranks alone. Well bar from balance the crank with everything else I.e. blue printing. But not to knife edge it ect. Could be different with other cranks. But I showed him mine and they just said to balance and polish it ect.

What sort or RPM are you looking for? i would use a lightened OEM crank either. Shell looks pretty awsome like and the rest of the spec sounds noice!

RPM isnt the goal, on the cams im using 7500 rpm is as far as theyll make anything.
accelleration is key, getting the rpm to lift freely is key reducing rotating mass and static drag through oil....
Im not after making high power, just power that is smooth, fully usable and the right amount for a balanced track car and daily runner ( when needed )

Id go for a billet then or just stick with pulling it out of the flywheel/clutch.

Exhaust Update
Update
Been looking into manifolds for the car and have decided on this one
Maniflow Competition with additional flex joint and 200cel hiflow cat added.
Not cheap but worth it
Spent about 30mins on the phone with them, really good to chat to.

Get Mike Edwards to make you a custom jobbie up, cheaper than maniflow, longer primaries and better quality too

Picked up Crank today looks really nicely done and feels a lot lighter, has been knife edged, flattened and balanced
then due to comments, spent hours looking into Frenchies and KE,L,B Cranks
End result... Its staying, I have found quite a few builds where they have been used, no one with any issues.
This one in particular seems to be very nice..
The only questions against are the end balance and how it effects harmonics at static rpms
To combat this I would suspect the use of either a fluid or stock harmonic damper would be best over moving to alloy pulleys, helping to maintain harmonic balance while still freeing up rotating mass... Opinions?
To be sure I am going to get it to a machine shop and get it re-balanced with full clutch, pulley, and rods/pistons
