I've always wondered how much integrity there is in redline display? Since BMW fudges (for legal reasons) the speedo, are the tachs honest? I know dynos report the honest number, but are they always directly correlated to the indicated tachometer? Could BMW just say the F8x redlines at 7700 rpm, paint the redline there and have the engine only turn over 7400 rpm at that point, or would the moon just instantly collide with the earth, kill all mankind and doom us all?

It would certainly seem like it on this forum if they did that.

Agreed. RPMs become like the Richter scale at some point -- every 100RPMs above 7,500 is an exponential increase over the previous.
*This is all figuratively speaking, mind you.

No, it's only 600rpm apart... Or 7,8%
Hardly worlds apart... The E30 M3 S14 engine had a rev limit of 7300rpm The E36 M3 S50 engine had a rev limit of 7200rpm The E46 M3 S54 engine had a rev limit of 8000rpm The E9x M3 S65 engine has a rev limit of 8300rpm Never heard much complaint about low rev limit on the prevoius straight engine M3's before... |

Yes, the pitch (frequency) is higher. But it's not like it's the sound of two different engines... IMHO You would need to be an "expert" to be able to distinguish between the sound this V8 makes at 7500rpm and 8000rpm... (33Hz difference) Last edited by Boss330; 07-25-2013 at 06:38 PM.. |

I appreciate the thoughtful feedback! It's certainly interesting to see the science behind it. Per my original disclaimer, though, I was referring simply to the emotion of driving a high-revving engine vs. driving one with a lower redline. Or put another way, when I had my S2000, there was a world of difference between how the car felt and sounded (and how both made me feel) when I would hold the RPMs at 7,000 vs. when I'd hold them 8,000 and at 8,900. The same goes for the M3: 7K RPM feels a certain way -- and 8,000 feels like something else altogether. Source: My unscientific brain.
