I know what acceleration is. I don't know how best to achieve it. My 2010 GT runs perfectly, and I baby it (12,500 miles). It seems to accelerate best when I am already at about 2500 RPM's, but maybe it's just the beautiful exhaust noise that makes it seem so.

Also, I have never revved the engine above 4000, and even that makes me nervous. Yeah, I won't be racing on the NASCAR circuit anytime soon!

Do all engines accelerate better from a high RPM level? And would it be good for the engine to rev it to at least to 5000 once in a while? I ain't going anywhere near that red line, though. Unless you guys tell me I have to.

Thanks,
Rob

As rpms increase the engine is literally spinning faster, which is how it can make more power, up until the point where it is no longer efficient, and then it will start loosing power. The power curve is like a slope, as the rpms increase, the amount of power increases. Most engines make peak power a bit under redline, for you peak power is it 6k rpm. So basically you ideally would shift a little above 6k rpm.

You drive a Mustang GT, enjoy it!

Thanks, four degrees. Shifting above merely 4.5k is "daring" for me, but I'll give it a shot. I thought the red line was the line beyond which you risk burning up the motor. Not so?

Redline is the limit for how fast the engine will rev, so yeah don't bounce off of it. Your redline is at 6.5k, try shifting between 6-6.2k. the only way you will ever experience the full rated power of your car is to be at 6k rpm. It's not going to blow up, it was designed to operate there.
