so instead of 50miles its 20 miles on battery? lol
compound supercharger
i think stillen putting one on a hybrid with a trunk full of nickel metal batteries it a little different than a supercharger made in some outskirts of hongkong off ebay powered by an optima at best lol. although i kinda wanna see some dyno numbers on this to see if it hurts the car or actually does nothing.
A lot less efficient. Turbos are powered by exhaust. That's as efficient as you're going to get considering the exhaust is serving no other functional purpose.
"Better" would have been a more suitable word then. Having to use the exhaust has its "cons" as well. If the power is available, then an electric powered turbine would be better then any turbo/supercharger kit available.
Yeah. The con of a turbo is lag. If the turbine was powered electrically (belt driven like a supercharger), you would eliminate lag. One of the pros of a supercharger. However, a supercharge isn't as efficient as a turbo because it is using the engine to physically power it. Rather than otherwise unused exhaust gases.
If it was powered by an electric motor then it wouldn't have a belt.
