No, not the ebay special that promise 1 psi
Thinking about turbo lag and heat problems. Part of the heat issue and lag is the way the turbine is spun - with exhaust. Why not make the turbo more like a centrifugal supercharger but instead of spinning the turbine with the belt or exhaust, why not spin it with an electric motor? Electric motors are good enough to drive hybrids. They have no torque curve, it's instant torque from 0 - infinity RPM's. The turbine could spin instantly and make lag a thing of the past.
I can't see any parasitic loss occurring from powering a motor. I'm sure some smart people could come up with something. So why havent we? You wouldn't need all that complex piping and you'd reduce the heat and lag.
Why not? I'm not an engineer so tell me where my thinking is flawed.
