Supercharger Tuning- electric "supercharger"

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.

It seems like the clutch would have to go on the S/C pulley so the belt would always be sapping power.

What I'm really trying to do is boost the idle to 1500rpm flat spot that my 4.0 Jeep has, I don't care if it runs out of puff at 2000rpm since I very rarely rev it that high. It seems like an electric S/C would be far more suited to the task than a mechanical setup. If it saves me a downshift on the highway or even means I don't have to regear my axles when I add bigger tyres it would be a huge win.

Yes a S/C can easily consume 20hp to run, but that's at redline where us Ecomodders rarely venture.

The clutched pully isnt going to waste near as much power as spinning the super charger all the time, which is the standard setup.

If you had a turbodiesel you wouldn't have to worry about turning the boost on or off.

You will find that you can add a kick ass turbo with plenty of fueling on any car.

a non Turbo 350 Chev responds very well to a aftermarket Turbo as does a Geo Metro 3 cylinder and every other car you put one on.


You should look into putting real Turbo on your car ,Re manufactured Parts are not so expensive and you will get hp rather then fan power.

Here's the restriction.

3" inlet - 2" outlet

Plus the impeller itself when not running.

Like Old Mechanic said you would have to have 2 different pathways for the air.

Oh, 2" is probably plenty big for most of our little engines. Even my V8s have smaller than 2" intake tracts. And an electric motor can probably freewheel just about as easily as a plain shaft on bearings, steady-state. So other than the inertial lag, having the dumb thing sitting there spinning- powered or not- probably isn't restricting the intake much. Besides, the engine doesn't know any better where restriction comes from so if there is some, opening the throttle a bit more will compensate.

Still applies to the glorified fan in the first post that can't create meaningful pressure

Except there'd still be a torque hole before all hell breaks loose. With ~18,000 miles on the clock an engine swap isn't planned.

I'm not really after 'power' I want off idle torque. I've got three turbo cars already FWIW Keep in mind that F1 now uses electrically spooled exhaust driven turbos.

Advantages of the electrical set up are torque where I want it, with the flick of a switch you can be back to OEM specs, if the E-S/C fails, you're back to OEM specs (handy in the middle of no where) and much easier to install (my Haynes manual lists 30+ steps to remove the exhaust manifold). Can easily return the vehicle to OEM. There's no good place to mount a turbo in a TJ, at least not for any of the conversions I've seen, and they all use pod filters that are a really bad idea on a 100% off roader.

Anyway at 9 year old and 18k miles the Jeep is getting a bit of a facelift over summer so we'll see
