I have seen some info about big manufacturers building electric turbos. Basically it's a turbo as usual but the hot side is a big electric motor instead of using the exhaust gasses.
I know some car manufacturers are trying to use this technology too i.e. Volvo has produced a tri-turbo engine with one of the turbos running off an electric motor and used to spool the other 2 turbos.
Some benefits of the top of my head:
- Lower temperatures
- Mount it anywhere instead of on exhaust manifold
- Electronically control the turbo through the ECU or standalone
- Easier installation
- No lag
Wanted to know other peoples opinion on this, I think it's a great idea.
