Again every engine has a powerband.
Say a engine reaches maximum bhp at 6000rpm. You want to keep the revs between 5000 and 7000rpm (powerband)
Do you mean does a vr6 give you a kick up the arse when you hit a certain rpm? No it doesn't as the bhp pick up is very smooth and no sudden kick in power throughout the rpm range. It also makes a lot of torque low down the rpm that is also smooth.
Edit. (Miss read) No it doesn't run out of power up the top rpm.
The cam in the 8v is poor. I changed mine and it pulls right up to the limiter
