let me help you out, its the year 2013. at the time of those engines, they "more" high revving. This new 2014 M3 will have a lower rev limiter than a 2002 BMW M3. also 600RPM is a lot, nice try though. |

Newbi question: At the risk of being slightly off topic.... why does it matter if it redlines at 8K vs something like 7200?

And, yes the redline is going "the wrong way" compared with the S65. My comparison was just to show that a 7700rpm redline isn't that different from previous gen M3 engines. And even though it might be redlined some 300rpm under the E46 M3, the S55 will have way more power... I know which I prefer given the choice of 300rpm more or 100+ hp more... I wouldn't mind if BMW had stayed NA either, but I suspect (or at least hope ) the new M3/M4 will give the competition something to think about. |

Agreed, that's why I'd rather have superior performance than 600rpm's extra... If you can't have both 8300rpm and better performance in the same package I mean...
I suspect the E9x M3 will be like a burger performancewise compared with the F80 |

I didn't have any good audio software on the computer and resorted to matching frequency by using this tone synthesizer http://www.philtulga.com/tone.html. Obviously Audacity is much more accurate with clear audio... I expected to be within ~5-10 Hz based on matching a few other cars really well. I have a new appreciation for hitting the rev limiter on the dyno. We need someone to get out there with a good mic and radar gun

I love all the sour pusses on this board hahaha. Some forum guy made an assumption based on something that is proven to be true within a margin of error and everyone bashes the guy, no to mention the car that isn't released and just about promises to be unconditionally awesome.
Cover the tach, lie about the weight, tell them it's naturally aspirated and said sour pusses will say it's the best thing since canned beer.

It's easy for a turbo engine to rev 8000rpm, Mc laren already did that.
What we need is low end torque (peak torque start @1500 rpm) AND 8000rpm redline. Mc laren peak torque start @3000 rpm |

Every journalist on earth said the E46 M3 exhaust note sounded like garbage when it first came out, everyone whined about the rasp. Now it's loved, go figure. This car, like past generations, will be amazing, and just like in past generations, the car will sound amazing [at high revs]. |

The S50B30 was limited to 7200RPM, the S50B32 upped that to 7600RPM.
At any rate they have been steadily pushing the state of the art and increasing max RPM since the very first M3, and that's largely why there have been no complaints in that area. This will be the first time they go back the other way for the M I6. Note that I am not suggesting the engine will be inadequate for this reason. Quote:
