Revs, how high do they go?

I was just about to post this. Might as well close the thread lol
Regardless of revs if you actually calculated the piston speed you'd find a lot of engines have pistons that are accelerating and travelling in the same ball park of speeds.
Eg vag 1.9 diesel 5000 rpm ish = 15.3 m/s
Honda nsr 500 , 13000 rpm ish, 16. 9 m/a
F1 engines are significantly faster mind at 24 m/s. anything that revs fast generally has a very short stroke. F1 engines stroke is < 40 mm.

The NSR500 ran about a 54mm stroke so at 13,000rpm it has a piston speed of about 23m/s. It's also a factory built race bike so doesn't count.Eg vag 1.9 diesel 5000 rpm ish = 15.3 m/s

A Ducati 1198 has a stroke of 67.9mm and will rev to 9750rpm which is around 22m/s.

Oh right I had read about 40mm stroke but I only had a quick glance for an example! A Ducati 1198 has a stroke of 67.9mm and will rev to 9750rpm which is around 22m/s.

That would be a much better video if it wasn't only available in 240p.Gassing Station | General Gassing | Top of Page | What's New | My Stuff
