I'm anxiously awaiting the results...
I know Darrin won't be pushing false info on us... Doesn't seem in his character, Not that I know him extremely well, but I wouldn't think so.
And as far as driving style effect MPGs... Doesn't really matter as long as the same person is doing the before and after, and they're consistent in their driving style.
I'm very skeptical, but also open minded, I don't know it all, but I DO know that our engines are extremely inefficient at Burning fuel, so If it takes some energy to make our engine more efficiently burn fuel, there is a certain point where it's plausible.
Turbos, and superchargers do the same... It takes energy to turn the pulley on a supercharger, but the energy it takes is less than the energy produced, on a turbo same deal, it takes energy to push the turbine on the exhaust, but it's more efficient at taking that energy and multiplying it.
So I say Plausible![]()
