The idea, suggested to me by John Fetz, is to get back engine power lost at high altitude (due to reduced intake air pressure) by boosting the intake flow using a gas-powered leaf blower. Since I don't have one of those, I used an electric one for the first experiment.
The leaf blower is a 110V/12A Black & Decker rated at 375 CFM. Gas powered leaf blowers can generate higher air flow (I've seen ones rated at 900 CFM), so I'm optimistic it will work.

But you are probably,,,,,, leaning out the motor! Extra forced air,, ...Motor speeds up, because that forced extra air leaning the motor.Would probably cause high E.G.Ts Hope that leaf blower has a extra long long retractable cord LOL!

@curtspray The ECU keeps the mix at an optimal level for the given intake manifold pressure.
