At wide open throttle at 100 mph with a well designed ram air system you may see a couple of additional horsepower, but not much more than that. The biggest horsepower gain would really be from using the coolest air avialable.
definately, get the air outside. It should be dramatic enough to reset the ecu, the battery, or however you do it.
I am learning now, even on a 23 year old carb little engine, it needed cold air
at all times, all temps...I feel rather silly about it. It is like I shrunk to a shrinking engine, and kept going the wrong direction. Anyway...outside air, big plastic tube, inert, as much as possible. It may pretend to be colder, it may pretend alot of things guages can't tell..just do it.
