Flat plane V8 from two Inline 4s

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Flat plane V8 from two Inline 4s

Post

I've been thinking about the possibility for Honda to produce a flat plane V8 by basically putting two F20C engines from the S2000 together, an F40C if you like. I would have thought that, as the F20C produces 240bhp, an F40C should produce 480bhp or perhaps a little more. I've read on another forum about the same idea and a guy was saying that it definatly wouldn't produce that much power. Comparing an F40C to two F20Cs i would have thought the V8 would produce more power because the use of only a single crankshaft would result in fewer frictional losses and therefore more power. Also, the reduction in second order vibrations in the V8 could possibly allow higher revs, again, producing more power. Am i missing something here?

I can only say that the S2000 engine wasn't meant for racing; it will be relatively heavier and there are no pneumatic valves to allow high rpm. As a road engine it wasn't meant for F1... although some of its theories might work.

Sorry it's a bit off topic, i wasn't relating it to F1. I basically would like to know the power differences between the combined output of two inline 4s vs a flat plane V8 made out of the same two engines.

Usually carmakers design so-called "modular" engines that can be made longer or shorter, "joined end-to-end" if you like.

ie. a V6/V8/V12 design. Never heard of an engine that's designed to be modular I4/V8/W12.
