custom_junky Posted September 22, 2009 Share Posted September 22, 2009 while in theory you could have an electronic supercharger, it is not effecient nor economical. first to create this monstrosity correctly you will need an electric motor that will have the power to turn a turbine through a set of gears to push enough air to make the "supercharger" worth while, not only that but you have to make sure that the motor can both speed up and slow down the turbine to match with the RPM's/fuel delivery, ie proper tuning that is no longer mechanically connected to the engine, this makes the response of the supercharger costly since it is now electronically controlled. i don't think that this will ever be a good answer...

mwiener2 Posted September 23, 2009 Share Posted September 23, 2009 Before you all bash something, you should read into it first. The majority of electric superchargers are complete crap and are more a restriction than anything. This product seems to be a well built electric supercharger that could actually work. Ebay electric superchargers draw around 15-30 amps. Far too little to move a significant amount of air. This device draws well over 200 amps. Enough to actually do something. This device is meant to be used on a small engines to boost low rpm torque... similar to how a hybrid system works. It is not meant to be used for more than a few seconds at a time. If the price is reasonable, I may get one and see if it can be used for pre-spooling a turbo hotside.

N.sane Posted September 23, 2009 Share Posted September 23, 2009 Joke's aside, the only legitimate bolt-on supercharger kit I've seen that might fit our cars is the one that Group A / Raptor Superchargers produced for the USDM Impreza recently.

mwiener2 Posted September 23, 2009 Share Posted September 23, 2009 what do you think your starter motor draws? Why are batteries rated over 500 Cranking Amps? Ever had the starter going for 30+ sec?

ScoopMan Posted September 23, 2009 Share Posted September 23, 2009 Might get a little funny at night when you have to floor it to get onto the highway. Headlights will get pretty dim for a few seconds. Considering our stock vf40 turbo pushes 415 cfm, I would reason than a 1.2 liter motor only needs half as much airflow pushed by this supercharger. Not a very big compressor wheel. It may have less mass than the rotor of the electric motor. I don't know enough about what kind of electric motors are out there, but the one in question spins very fast, very quickly. Initially you need a spike of torque to overcome the inertia of the wheel and motor itself to get it spinning, after that you have a steady state overcoming friction and maintaining whatever airflow they are engineering for, 200 cfm or whatever it would be. Anyway 200 amps at 12 volts is 2400 watts or about 3.2 hp. A lot stronger than a hairdryer. Should be able to push some air with that. Link to comment Share on other sites More sharing options...

05lgt5spd Posted September 30, 2009 Share Posted September 30, 2009 No different than a HVAC motor which might pull 30A on startup, then kick down to 10A. Locked rotor current is alot different than continous current. Link to comment Share on other sites More sharing options...
mwiener2 Posted September 30, 2009 Share Posted September 30, 2009 I'vehad my motor cranking forover 30sec at a time. Followed by several more long cranking cycles. Ever see someone kill their battery trying to start a car? That's several minuets of cranking. (or not very long if your battery sucks) No different than a HVAC motor which might pull 30A on startup, then kick down to 10A. Locked rotor current is alot different than continous current. That's 120v AC. Very different kind of motor. What's your point anyways?

05lgt5spd Posted September 30, 2009 Share Posted September 30, 2009 Point is that if the motor draws 200A, at given times, It could be drawing 100's %'s higher. I think 200A of continous load would kill your battery. Unless you found an alternator to support 200A plus the load of the cars electrical system. And even if you found one to support it, you would probably need a couple batteries and caps to take the draw off your car when the motor kicked on. Basic AC theory is the same as DC. Different kind of motor, but same laws apply Link to comment Share on other sites More sharing options...
mwiener2 Posted September 30, 2009 Share Posted September 30, 2009 Electric Supercharger Variable Torque Enhancement System Startup 350a Running 220a Full speed 70,000rpm time to full speed <350ms Pressure ratio 1.45 I can't find the specs on our starter motor, but I bet the starter draws more than 200 while it's cranking... probably more than 300 with a cold engine. It's not meant to be used constantly which means there should be plenty of time between uses for the alternator to charge the battery. And so what if you need to put a honker alternator in. You're custom fabing an electric supercharger onto the car. A new alternator is part of the game. Aside from the fact that this thing will max out around 5-7 psi... which is pretty good considering it will do that at idle... actually, that's really good. This thing just might work after all.
