I've had my car for a year and it's only recently I've taken the car up to 6000 revs. I've never taken it into the red.

As mentioned above, it's a performance engine and should be treated as such (occassionally). I find my mood varies. Sometimes, especially when driving to work, I drive it moderately in order to preserve petrol, but on weekends I like to take it for a spin on some stunning local B roads and rag it. Make it sweat.

To be perfectly honest, the car sounds great at about 3500rpm (especially with an induction kit) and just above that is usually when I change gear from third to fourth and then into fifth for a constant speed.
