why obsess over rev limits?
 

why do people care so much about this? i mean i understand that nobody wants a diesel in this thing but when i see comments like "if it doesnt have a redline of 8xxx im not buying this." ill admit that it is kind of a neat novelty but a if a higher redline doesnt mean more power, what is the big deal?

I could care less about high redline 4 cylinder engines as they make shitty ass torque(IMHO) in the range that matters to a daily driver 2k-4.5k rpms. The only time I will care for a high revving engine is when it has 6 or more cylinders.

Power is torque x rpm, so a higher redline DEFINETLY means more power..
And having a higher redline means you have more revs to play with ;)

I don't get it either. At first I thought they were troll posts, but I began to see them more and more. I couldn't tell you what my Miata redlines at, and I don't care. Fun is definitely not RPM dependent.

Divided by 5252. If your torque falls off enough, you're not going to make any more power no matter how high its redline may be.

More rpm doesn't necessarily mean more power, but if the rev limit is higher that suggests there is more power since the manufacturer wouldn't give you more revs if the power dropped off. Of course this is design specific, if the engine has higher specific torque then a lower rev limit doesn't necessarily mean less power, but the specific torque of engines with the same displacement is about the same.

At the end of the day, everything people are asking for is MORE POWER. lol.

More revs mean you can use gearing to better take advantage if the limited torque available from a small NA engine. Plus high revs can be fun to drive. I'd prefer shorter gearing and higher revs myself.

:bow: ding ding ding, its not about makeing hp its more trying to maintain trq band, when you shift gear rpm drops but if you can shift on a higher rpm you can stay on a higher trq band.

it depends on your tq curve. if your tq is going down, and you increase the rev range, you can get to the point where the next higher gear will actually make more tq at the wheels. granted this is more prevalent on large displacement V8's where peak tq is down low, but the point remains...

it never ceases to amaze me some of the stuff that's posted here. test drive an ap1, then compare it to your miata. it's a personal preference, but when you drive the ap1 hard(9000 rpm redline) it should be quite obvious why so many people like high revving engines.

I'm used to the power coming on above 8K and redlining at 14K! :popcorn: ;) That high reving whine is music to my ears!

As I mentioned before, I'm going to assume this car will redline but @ 8k but peak out around 7,700. Who doesn't like a rev happy engine!

I like high revs... Can change gears and get moving faster than if the rev limit was at 4k. :x

I like it also comes in handy when you're on the high way and you're coming off from a circular on ramp with a stupid stop light and cars merging into your lane. :x

A sports car is about power on high rev and not about torque. It is about not about power or torque but HOW power and torque are delivered. Power should be linear till redline and the torque curve should be as flat as possible. You think you get a flat torque curve with a turbo? Maybe in low range, but upper there is nothing left, and at the beginning there is also nothing unti lthere is no boost. Just look at these two different engines. The N54 is a turbo engine, with alot of torque in the mid range, but nothing around. The S54 is a naturally aspirated engine, has less torque but a completely flat torque curve. The power delivery is linear, mcuh better to drive in a sporty way.

Higher revs means more area to play with in one gear, and even if it drops off you can keep accelerating without shifting which is very important when you have a corner coming up. Dont want to go 3>4>5 for a sec then 5>4>3. Much rather hit the limiter in 4th or keep accelerating if you have a high revving car.
