there was a video posted on her about a guy showing off the sound of his exhaust, and then it shown his rev counter. and everyone was saying how he cudnt drive his car properly coz he kept redlineing it. then sumone mentioned a power rev or sumthing, like the exact time to change gear to get better shifts and better performance and more speed outta the car.
cna anyone clarify what was being said?
The more power your engine is producing the faster it can accelerate. The power curve - how much power through the rev range - is like a hill. The closer you can keep the engine to the revs at which the hill's peak occurs at the faster you can accelerate. So on a car where the peak is at 6,000 rpm you might change up at 7,000 rpm, which would cause the engine to drop back to 5,000 rpm, then accelerate until the engine reaches 7,000 rpm again, then change up again. That would keep the engine closer to its power peak and produce more acceleration than only revving to 6,000, or revving all the way out to 8,000 rpm.
What the best revs to revs out to before you change up depends on how rapidly the engine's power falls off after the power peak, and how widely spaced the gears are. But you should never wait until you actually hit the rev limiter because as soon as it cuts in your engine is producing very little power.
It happens that because the Clio Sport engine's power doesn't fall off particularly rapidly after its peak at 6,500 rpm, and because it doesn't have a particularly close ratio gearbox, the best point to rev out to is as close as you can get to just before the rev limiter cuts in. And Renault conveniently gives you a little light that comes on just at that point telling you "you're almost at the point where the rev limiter is going to cut in, change gears now".
quite reassuring that when mines on the limiter its not doing too much harm then. Although saying that I still don't fancy it staying there very long :nono:
