The electric motor to be used would have to be a pretty unusual motor. IMO, supercharging is "better" because the PTO side of an engine is less ... trouble than the exhaust side. Superchargers are generally heavier.
- hvidgaard 10y agoSuper chargers generally result in a fairly large parasitic loss to power it. Turbo more or less harvest free energy with only a minimal loss due to increased back pressure.
- ArkyBeagle 10y agoSo they say. The story I always got is that turbo ( for aviation - where this all grew up ) was simply lighter. The old rule of thumb "turbo costs 3x less than super" is true for a lot of cases. Supercharge provides a linear boost where turbo does not.
- hvidgaard 10y agoSome superchargers provide linear boost, others behave much like a turbo. In any casem FI is used to increase efficiency, so it doesn't make sense to use a super charger with a must larger parasitic loss. Modern turbo can provide boost from 1500 rpm, and result in a flat torque curve - the only negative thing is the lag.
