Electric Turbo!

-
I saw that Roadkill episode, too funny!

I'm thinking LI batteries to power the turbo. only need it rarely and for relatively short bursts, batteries kept fully charged all the time with a 12 V LI charger tied to the car battery.
 
I see ZERO advantage, and what you have essentially done here is turn the exhaust powered turbo into a belt drive blower, just like a paxton. WHY? Because the ALTERNATOR is belt drive and it now has to supply the power to spool up the supercharger. And it takes a LOT of power to run a blower.

I'd be lookin for about a 300A alternator

I understand where you are coming from... I see it as a NOS like device. Where you add boost ONLY when you want. 98% of the time it would not be used. If it was hooked up to a LI battery, like a jump starter battery, (lots of current flow for a short amount of time, but a lot of time between to recharge the batteries) the batteries could be recharged with a low current source.
 
I have heard rumors that the new Chrysler inline 6 is going to have an electric turbo.
 
I like it ! We dont drive full theottle all the time anyways.
Its kinda like hockey.... the average NHL player only has possession of the puck for about 45 SECONDS in an avg game !
And we dont drive full throttle much more than that on the street. So unless you are racing a rod course it wont matter.
 
I looked at their website and looked around. They use a 7HP motor to run the turbo.

Mad Max called and he wants his Switchable Blower idea back.

If you "assume" that motor is say, 70% efficient, that means it actually consumes about 10hp electrically. The electrical equiv of 1hp is about 800 watts, so 800w X 10HP is 8000 watts. At 14V, that's 8000/14 which is about 572 amps.

LOLOL so my initial guess about a 300A alternator was a little "small"
 
Their website said 5000 watt electric motor, and online converter said about 7hp mechanical

They supply a controller and a battery with built in charger. They claim 10 seconds of charging for 1 second of boost., No special power for charging needed.

Supercapacitors. Charge up fast, discharge all they got over about a 30 second span into a 12v device with huge amps. Trouble is pumping a constant 9psi into a running vacuum (motor) take a grip of power in itself. There is no free ride. Dont know why they dont just inject compressed air out of a tank instead of having the motor draw it in. Instant power, supercharger like response with no parasitic moving parts. Its called CAS, compressed air supercharging and it isnt 'new'. 850 HP on 10 psi on 91 octane. Whats on the lift at 1:59?
 
^^Just to be clear^^, either a cap or a battery "pretty much" takes the same energy to "charge" it as whatever you expect to get out of it, less the inefficiencies of each conversion. As you say, there is no "free ride"
 
Art Malone ran a CAS car back in the 60's. It takes one 300 SCF bottle at 2500 psi to power a 350 SBC at 14 psi for 15 seconds. Dont know what Art ran back then.
 
Lame-O
Oh gee, it had to happen; somebody came to preach sending horsepower into an alternator, to generate electricity, to charge a battery,to send electrical horsepower down a cable, to drive an impeller,to supercharge a mini-me engine; that could totally be handled by a slightly bigger displacement.
Lame-O.
On the street, the whole modern idea of a turbo pays off because it helps the small displacement engine make additional bottom-end torque to get away from a stop in a reasonable amount of time.
Take your small displacement V6 turbo-charged gas pick-up with it's four or more speed automatic, for instance. I know more than one guy that, after the turbo packed it in while towing, swapped that rig for a good old fashioned NA large displacement V8 truck.
Getting stuck a thousand miles from home with a dead turbo, puts you at the mercy of some pirate out there who is gonna rake you over, cuz he can. Not to mention; your vacation is officially over; send the wife home on a plane, cuz this is not what she signed up for........... and she is gonna be reminding you about this for a good long time.
So now, what happens when this little electrical bugger packs it in? Or takes the wiring out? Or melts the alternator? Wait; back up the bus; just exactly how big is a 600amp alternator anyway,lol.

Appears to be a later model Duster based on the hood
 
I think one of the auto mags did a write up on how BMW was looking into a large belted generator on a clutch, looked like a huge alternator that they claimed added 100 ft.lbs of torque just by turning it on. It was designed to aid when downshifting or passing or starting from a stop...something like that. It was just another component under the big plastic cover under the hood.
 
I gotta laugh;
About a year ago, I bought a 2014 Chev Orlando; basically, a high roof wagon. It comes with a Direct-injected. variable valve timing, 2.4 EFI, 167hp@6700 4banger, and a close-ratio 6-speed auto with loc-up; all in a 3600 pound chassis. It motors pretty good on the base cam timing, and at 4500 the VVT cuts in, and then hang on; well in second gear hang on anyway. For downshifting and passing at 55mph, it makes a good effort but you know.... it's still just a 2.4 liter.
Thing is; if you pulled that fancy-smanchy power unit out of there, and all the support works, and dropped a 5.2 Magnum/A500/3.91s, into the hole, the only thing you'd lose is the 32mpg; but you'd gain so much more, in power,torque,reliability, etc.
The point is that for all the technology the manufacture's have brought to the table, since the 70s, in order to use these tiny engines, the only desireable thing we the people get out of it, is a few more mpgs, and 7 friggen airbags. But all the money we save at the pumps, gets used along the way in maintenance and complicated expensive repairs; whereas the Teener-TF is about as stone-anvil reliable as it gets. I'd prefer the meager 20/25 mpgs and drive it forever character, of the ancient power-unit. And you can keep yur stinking traction control, yur stinking ABS, yur stinking 7 airbags, yur DI-VVT,yur plastic engine cover designed to lull yur brain into thinking there is so much more under the hood than the stinking 4 pot pos that was in your 1984 Hyundai-Pony, and I'll even accept a carburetor. And that Magnum, to make 167hp, now at half the rpm, don't need no stinking turbo, no super, no hi-test, no nuttin-honey,
and especially not no electric scroll-fan;
just drive it.
