pissedoffsol

neat! all supercars and hondas. lol

Drake

Thats pretty cool. In what situation would you want to know piston speed though? Would it help in designing full blown race engines? Have as much information as you can about somthing is always good though.

Silverchild79

Honda also dominates the top ten for vehicles that would own if they weren't FF..

d.b.cooper

No American car manufacturers on the list.

I had the aptitude and the interest for automotive engineering, but looking at the CRAP available in the late 70's to early eighties being produced convinced me that if any of the US makers had engineers, they certainly werent listening to them!

8. Saleen S7
Engine Code: N/A
Bore/Stroke: 4.13" X 4.00"
Redline: 7000rpm
Piston Speed: 4666.67 Ft/min

I'd have to say that's american

Calesta

Wow. Impressive list.

For the person who asked about piston speeds- they're very important in designing the combustion characteristics of the engine. Obviously, the faster the piston speed, the more difficult the design- but that's an oversimplification.

Just did some simple math... so the pistons are all moving at less than 60mph at top speed? That doesn't seem right. I guess I need to draw some curves, but at first glance it just seems a little weird.

asmallsol

I could see that, cal, the accelration needed to get to 60mph in 84mm (in the f20c's case) is astronomical. Also I would assume that the highest speed is right in the middle of the stroke because for the first half of the stroke its speeding up and the second half is slowing down. So in the f20c's case its doing that in 42mm's. For the s2000, the max speed is 25.22 m/s

using v.f^2=2as, and using 42 mm's, then the actual acceleration needed to get to that speed in that distance is 7572 m/ss, or in terms of g's, the piston accelrates at 772g's. I am really interested in the mass of the piston to see the force it takes to slow them down.

I like how there is one sport bike on there, you think sport bikes would dominate the list if they listed them all?

reikoshea

yeah, cal, you have to think, that is a nearly instantaneous 0-60....so yeah, its pretty fast if you think how quickly they go from 0 and then immediately to 60.

Calesta

Yeah, that's why I said I had to draw up some acceleration/deceleration curves. The dv number has to be huge.
