Sorry for the delays guys.. I've got a large order pending for these 82mm bodies. I just need to plug them into a few more cars and make sure all the electronics work properly.. Since I dont have an inlet to bolt it to I cannot fully install it and test it on the road.
As long as the electronics check out and the throttle plate moves as expected then I know that everything will be fine when they are installed..
I will make the bodies available once I've had a chance to verify all of this.

If the M275 is the same design Benz usually uses for their V12's, and like the setup that came with my M120, then you probably have two completely separate 72mm or 74mm TB's, one feeding each cylinder bank. Pretty advanced design.
If that's the case, then the bottom line for your motor is that there's probably no worthwhile gains to be had with larger TB's. Because you have 148mm of total capacity already, your motor would probably need to be pushing 800+hp before that would ever become a real constriction point.
I'm sure there might be some very slight gains to be had with larger TB's, or with a port and polish job, like a couple rwhp maybe. But you'll never see that huge 60hp bump that the 55k guys will, with their 500hp+ motors sucking through a single 72mm-80mm TB, because your motor doesn't have that capacity constraint at the TB in the first place.
If you can verify that your motor does have the twin TB's, then I would skip this mod, it's never going to give you a real bang for the buck.
