Phantom Supercharger- a new Performance option? - Toyota Nation Forum : Toyota Car and Truck Forums

this is an electric supercharger, discussion of the electrical details... it is set up for short bursts only, ie on acceleration. The evidence and testing is not as rigorous as some do here but its fairly convincing

Awesome, I've always wanted a forced induction set up for my Jeep but didn't want the FE hit of a S/C or the cost (and lack of low end) of a good turbo install.

This looks like it will fit the bill and best of all, if it fails the vehicle just runs as it did in original form.

Could this produce 3-4 psi in a small displacement engine as advertised ?

Possibly.

However.

It would seem to me that when it is not running it would be a restriction in the intake therefore increasing pumping losses.

If the issue is an intake restriction then I would devise a flap that was closed when the supercharger was operating and otherwise open until the supercharger's pressure closed off the nonboosted pathway. A rocker flap that only required the preessure to exceed ambient pressure to change the charge pathway to through the supercharger.

But I still like the idea of a positive displacement supercharger that would replace the throttle plate, where the restriction was utilized for some electricity generation. It would not be much but you have to consider the duty cycle where the supercharger was actually providing pressure. In my case, I seldom see over 3500 in the Fiesta, even through a whole tank of fuel.

I think the electric supercharger has a future, when combined with an engine like the ecoboost with reduced displacement, so in my case the engine could be less displacement which means higher load for the same vehicle speed and better efficiency under all operational parameters.

It would also mean start-stop would not have to deal with cooking the oil in a normal turbo setup.

You can get the same on off effect with a clutch on a supercharger.
These compressors have to put out 10 and 20 horsepower worth of air to provide boost. Not something easily done on a 12 volt system.
It can be done, there is an electric super charger out there that does work. Its a screw type compressor with what looks like 3 starter motors powering it. That thing had like a 10% or 20% duty cycle if your electrical could keep up.

I would just go with a clutched setup.

I would just rev a little higher, or forget it.

It costs $2000 and will sap hp & gas from the engine via the alternator load.

I could buy and install a traditional waste gated Turbo for less money with MUCH larger gains.

For instance with my Waste gated Turbo I can buy a over sized intake manifold from Europe for $250 then add larger fuel injectors $200 plus a $60 chip replaced in the ecu and The car will jump from 90hp to over 220hp.

I think you will find a traditional Turbo is not as expensive as you think , if you buy the parts Online re-manufactured or used / rebuilt & do the work yourself.

This only holds true if there's an OEM or off the shelf setup to duplicate. For most cars that's not an option.

I don't beleive it will. If you accelerate at BSFC your reducing your acceleration time and you're then recharging the S/C battery 'off peak'.

If the impellor is on a one-way bearing, the restriction would be minimal.
