Electric Supercharger's
Im looking at getting an electric supercharger for my b20z engine, just wondering what your ideas were? performence wise and reliability wise...
cheers...

Re: Electric Supercharger's (sepetinswenze)
i remember watchen a guy around here design and install/test them on differnt cars. Honstly. made 13whp on a turbo gsr, it helped spool time. Also tested it on a o3 cobra and made like another 21whp if i remember right but its not something id ever buy. there peices of **** in my oppion. Just spray your car with a 50-75 shot you will be happier. or save up and go real boost.

They are for real.I would think reliability would be good.They are very expensive/hp.

Re: Electric Supercharger's (NJIN BUILDR)
It has been proven that they CAN work. Sure, the physics is there, and these units that use 3 STARTER MOTORS deliver enough power to deliver the boost. But you have to ask yourself, why?
1) You need to rework the entire charging system for them to work.
2) The are just as expensive as a turbo.
3) After all is said and done they are heavier than a turbo system.
4) They draw massive power from the charging system, and that power comes from the engine. Because of copper losses, they are less efficient than either turbo or supercharger.
Now, there is a place for these things. When hybrid cars start to come down in price and people start modifying them, I could see the electric supercharger being a good option. A little more current draw on the batteries and a little more fuel burned for better acceleration. Not a bad idea for those underpowered hybrids.

Re: Electric Supercharger's (beepy)
Actually, I have links to a multi-part article where they put a turbo on a prius. Not only did it help gas milage, but boosted power (both nearly doubled). Cruising it ran ~1.5psi, so it was working hard.
Anyways, running such that uses an actual roots-style SC would mainly help spool the turbo. Ideally it would turn on between idle and a when the turbo starts spooling, then turn off and open up a bypass around it. As long as its set up to draw more power than the alternator provides (using extra batteries as shown), it will still add power. The cheap ones (glorified house duct fan) won't be much help at all.
A much better solution is dual-charging, using a slightly modified SC setup with a turbo before it.

um, doesnt the gas motor in the prius just supply electricity and its actually driven by eletric motors?
i don't see how it would get anymore power from that.
