If you can put more air into an engine then you can increase the fuel supply and produce more power.

If the Cobra is kept under 80 mph it probably doesn't matter either way, but a disadvantage to using a carbureted engine with a set fuel delivery value might be you don't have a computer to increase the fuel as load is increased with speed and while exponential amounts of air are being forced into the engine the faster you go.

It seems logical that the choice is either tune the engine for cruising around an have lean conditions at high speed or tune for high speed and have a rich condition at low speed. A forced air system without a computer seems would increase the effect.

Lower temperature air entering is always an advantage.
