With regards to iforb's post, the rpm at a certain speed is determined by gearing ie if your top gear is 40mph / 1000rpm then at 2000 rpm you'll be doing 80mph, your power upgrades won't affect this, apart from getting there more quickly The additional power and torque means that you are can probably travel around in higher gears.

You need a certain amount of power available to stop the engine from stalling.

Without changing the gearbox or overall drive ratios, then you will still have the same speed at the same RPM. It doesn't matter if you have a million horsepower or 50. As long as you have enough power to turn the gear, then at say 90 mph in 6th, you'll still be around 2500rpm.
The amount of throttle you are using will be very different though, as with more power you need the same power to hold the speed, but the amount of throttle needed to give you that power is less.

Another way to think about it is that if you hit the rev limiter in each gear already with a standard car, then with more power you'll still hit the rev limiter at exactly the same speed. The only difference is that you'll get to the speed faster as you accelerate quicker.

Think i get it now guys, i wasn't thinking properly. Thanks for the help
