I was wondering does the cylinders of a S2000 engine at 9,000 rpms work harder than the cylinders of a F1 V10 engine at 18,000 rpms?

 

No.

 

For anyone that likes to say there are no dumb questions, please remember this post before you ever say that again.

 

Actually I remember something about the S2000's much longer stroke producing higher piston speeds than an F1 car, even at much higher RPM's. I'm pretty sure I read it on this board a year or so ago.

actually the car with the fastest avg piston speed is the E46 M3 (production car)
It was about 2.5 meters/sec slower then an F1 car's pistons. But, there is more to how "hard" an engine is working then just that.

 

C'mon Rev - Back off! If you feel that this was a dumb question, then there's no need to comment - just ignore it and move on.

 

Alright I found a Road & Track article talking about the piston speeds of the S2000. http://www.honda-s2000.de/05archiv/presse/...9_rat_79_gr.jpg

From Road & Track:
"Although Formula 1 engine bore and stroke and no longer published, their current maximum piston speeds are like in the range of 4500-5000fpm. When we do the numbers for the S2000, we find its pistons stroking out a racy 4575 fpm at peak power (8300 rpm), and a whacking great 4960 fpm at the 9000-rpm redline. These F1 type numbers in a production engine shows that Honda isn't shy about pushing the envelope." Road & Track magazine August or September of 1999

 

What about cylinder pressure? I thought that was another parameter for the "engine working hard"?

 

Piston Speed in FPM = (Stroke (in) * RPM) / 6
