I can't speak for Mr. Bello's car, or him. Is 700 possible via a bar of boost. Yes.
Is there any question that Mr. Bello's car is not fast, not really. It's a very quick machine indeed. Mind you not the only one around!

But then it depends on the modifications and methods applied to get there, and I don't place much weight in everything a dyno read's out. Some dyno's are quite sophisticated in there own right, but having them calibrated is one factor often over-looked. Then you have many dynamic variables that a come into play on a vehicle that ( a lot of main stream ) dyno's are not calculating on.

Dyno's are helpful in many ways, however they should treated as a piece of lab equipment that is to work in conjunction with a verity of other dynamics.
