This motor is an engineering marvel. This is a seriously bad ass motor and from what I read it is very under-tuned. I'm guessing we will see these putting out some serious numbers way higher than what they put out from the RuF factory.

The pistons act as the counter weights, therefore there is less rotational mass (no crank counter weights) which allow the engine to rev higher. I'm very impressed.

The fact that it will have a "FLAT CRANK" V8 engine, will make it VERY special motor and with a 8500rpm redline it should sound incredible. I cant wait to hear this thing.

From what I understand, flat eights are not as balanced as flat 6s and V8s. I know a flat 6 is more balanced than a V8. Is this true?
Also, many V8s are lighter than flat 6s because they don't have individual cylinders. Siamesed bored v8s are light and strong. Considering even the LS1 is lighter than a flat 6, this could be a very good thing. Also take into consideration that a new GT3 motor only lasts 100k miles, a detuned v8 putting out the same numbers I would expect to last longer.
Don't hate just because it is new and not what you have. This motor doesn't make your flat six and less of a great motor.
