OT: Which Engine Configuration has the Most Power?, Curious Minds Want to Know Options

[Britain Smith]

I was discussing the engine layout of a Porsche motor in a horizontially opposed configuration and the question came up on which engine configuration produced the most HP/liter and why? I know that an advantage of a Porsche motor is that the center of gravity is really low, but does its configuration have any power advantages when compared to say a 90 degree V6 or an straight 6? For simplicity, lets keep the discuss focused on normally aspirated motors. What are you thoughts and why?

I believe the current Rx-8 makes about 238 HP @ 8500 rpm from just 1.3L I think that little bugger has this contest beat. It has a redline of 9000 rpm!

The only people that call one 1.3 L work at Mazda.
The FIA call it 2.6L....still, gud hp, no torque.

If one is totally unfettered......the most hp per liter I ever heard of was BMW's FI turbo engine.... an estimated 1500 hp from 1.5L in qualifing trim. 80 ish lbs of boost....a 4 banger.
It got down to the least amount of frictional losses.
