While its not good on the charging system, and it won't produce any boost, these electric turbos can give you a small increase in power for a short period of time. Its proven on a dyno and at the track. So yes its a myth still because i still see it claimed to boost the motor, but its not a complete lie as there is a couple hp to be had. Obviously the size of the motor will matter as it would with selecting a REAL super or turbo charger.
