How significant does acceleration affect fuel distribution and HP?
I was wondering about all this talk about dyno HP, but it's not a true enviroment of racing, and one of these multiple aspects involves G-force, and its affect on fuel distribution in the intake manifold. I was told that with NASCAR, when the cars are under high cornering G-force, there can/is substantial alterations in fuel distribution, which I would think affect HP.
With drag racing in a normally aspirated car, , with acceleration, there is obviously some G-force with acceleration. In a 11 sec 1/4 mile car, would there be significant fuel distribution changes that occur as opposed with running the engine on a dyno? Is there a difference between single and dual plane intakes?
