RS Engine Problems
#31
Here's another way to look at it: if the RS made the same power / torque figures, but the redline was at 9,000 RPM instead of 8,800 RPM (looks like it shifts at 8,600 RPM in PDK sport, too), would you like that more? I think the honest answer is yes, for cool factor alone...

I have to say, though, there is something unique about RPM in terms of sound. Same power at 6,000 RPM vs. 9,000 RPM certainly has a different sound / feel.

And its cylinders are only 500cc each. If the RS had cylinders that size it would be 3.0L and could easily rev past 9k (but still not make over 400hp and ~250 ft-lbs). I think the extra 100hp and 88 ft-bs is a pretty good trade-off for lowering the redline slightly, no?

Maybe, if you could jump on it all day all night without problems for 100+k miles add a turbo and you'll have the upcoming next generation Porsche engine.

BTW, remember when Honda increased the displacement from 2.0L to 2.157L (less than 8%)? They lowered the redline from 9,000 to 8,200 rpm.
Well, the RS has cylinder displacement expanded by 27% over 500cc and it still revs to 8,800rpm. That destroys the Honda numbers (as well as the old 3.0L aircooled motors above, though the 3.0 RSR was pretty awesome)...
