Has anyone done testing to understand the Net difference between single and twin plug on a /4?

So, lots of cool responses.
I am curious if twin plug, large displacement enables slightly more HP, and a better more efficient motor. I think these motors were something like 35% efficient. Certainly a less costly road to travel versus a /6 |

Certainly a less costly road to travel versus a /6 Not sure how much you would gain (perhaps a percentage or two max I bet). I think you might end up using the second plug to compensate for the decrease in efficiency with a much larger chamber? They definitely aren't 35% efficient. That's F1 efficiency territory (no KERS), and higher end than pretty much any production cars. |
