Moon Tricky - no, the 30% number I gave is a different 30% to the number you were trying to work out.

Looks really nice tucked down so low into that sports car. The firing order would be the same as a boxer six? As a low engine package, it reminds me of Formula one when it became a sort of engineering trend to bring down center of gravity with the wide angle vee 10 like Renaults 111 degree(or 109). Probably with the crank mounted so low it might have an even lower center of gravity than a boxer while using a much simpler crank, maintaining a shorter engine length. I'm not clear on its balance though. I'm still facinated by a 120 degree vee 12 and have always been.Originally posted by Engineguy

a 120° V12 would be quite a beast. You'd have to have each crank pin 60° ahead of the last, instead of a straight-6 style crank, otherwise you'd get two firing events at once. The crank might be a bit stronger, with more overlap of one crank pin with the next, although would you need a balancing shaft?
A 144° V10 would also work.

What the world really needs, IMHO at least, is a flat-8 , short-stroke version of the LSx 5.0L , 500-600bhp depending on emissions, 7500rpm redline, 140kg all in a relatively compact package...

That'd be a hard engine to love. It'd sound like a 4 banger, oi tink.

That's only with a flat-plane crankshaft with shared journals and double firing intervals. Not very appealing at all... Proper flat-8s should sound like a flat-plane V8, but without the vibration nastiness (if the proper crank configuration is selected)
Check out this video for a marvelous demonstration of what a flat-8 sounds like:
