Just goes to show the NSX's engine technology isn't exactly at the forefront anymore... but also shows how much room for improvement there is too!

 

[goldNSX]

I would say that the NSX delivers 8000 rpm with a unknow reliability before.

 

[dave22]

I'm the winner!

What does piston speed have to do with technology or room for improvement? I think it's just a function of RPM & stroke length. Faster piston speed doesn't have a direct corelation with better performance.

Otherwise you're also saying the engine of the 2001 Acura Integra GSR is technologically superior to the Ferrari Enzo motor which has lots of room for improvement in comparison.

Piston speed obviously has a connection with a motor's specific power output. The S2000 engine has the fastest piston speed, and also one of, if not the highest specific power output of any mass produced engine.

The NSX engine makes 90hp/L from it's 3.2L engine, whereas the S2000 makes 120+... Piston speed and specific power output are relative, as to achieve higher power output for the same capacity, you need to increase the RPM, in turn increasing the piston speed.

I understand that it's "just a function of RPM and stroke length" but why would they bother engineering an engine to be strong enough to acheive such high piston speeds unless it was in the pursuit of additional power?

Where I work we use piston speed calculations all the time, but not in the manner for maxiumum hp/performance out put.
We use it as a formula to tell how much stress load we are putting on the lower end of the motor without all other components considered.

The NSX is low in a good way and I wouldn't hesitate to keep RPM's high for sustained periods of time which is excellent for high speed road racing.

If my memory serves me correctly, Csaba Csere wrote a great column some years ago about piston speed, mass, and forces exerted in an F1 engine (of the era). I'm sure Ken (Sax) could steer us in the right direction toward that article.

Ken?...

ChopsJazz,

How long have you owned your NSX?
Your license plate rings a bell.
The last NSX meet I went to was about 6 years ago, maybe more.
We went to an airplane museum and then a 2 hour drive in the hills.
Did we meet? The only other thing I can remember is you asked me which exhaust I liked and you may have had some kind of sticker on your window.

[ChopsJazz]

That's me. In fact, that was my first big organized drive. My sister came along with me. It was a blast.

The sticker? Skip Barber Racing School

Holy thread ressurection.

Piston speed of the new 2013 450hp Audi RS5 is 5000ft/min.
