Electric Supercharger on Ebay
You'll like this, not a lot, but!
Ebay Linky
"Not your usual rubbish"
"3 phase! 80 amps!"
Anyone got a masssssssiiiivvvvvvveeeee extension reel?

3 phase supply.
Thats a long extension lead!

100 quid ! Worth it for the inverter alone.

dont touch it with a barge pole!! unless you want an hair dryer, even then i cant be sure it would finish the job off!!

Funny you should mock, as i did, but it transpires it's the future. At least it is for companies who can actually design and manufature such a
thing. The posibilities of boost control are rather exciting.

its never going to be as efficient as a regular supercharger due to the two extra energy conversions. I would think it better to put the effort into
controlling the boost of your existing supercharger.
However, this device as it stands, as an addon for NA engines, surely it would be better to market a supercharger that was a replacement for your
altenator, and have a small genny function on the back of it?

I'm not saying the item in the link is the future, just that supercharger/vehicle manufactures are looking at it as a way forward. The advantage
comes from the boost control, and spool times, giving much better controlability and tuning potential, giving high boost at cruise, thus needing a
smaller engine and such like.
It also turns out that electric would be a suplement to turbines, thus giving a faster 'idle' speed, and less acceleration needed to
achive the required spool speed.

Motorbike alternator to a regulator rectifier converts to 12v DC. He says it has an inverter supplied with it for a power supply It looks more like a
forge blower than a turbo/supercharger to me.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Not that I know much at all about turbos, electric or otherwise, but a quick search reveals:-

Would appear to be a genuine company.......
If its broke, fix it. If it aint broke, take it apart and find out how it works!

It could be 12volt 3 phase as many model aircraft use similar motors .They are brush less 3 phase and the speed control is a dc to 3 phase
inverter.They use them in large models now and get similiar performance to ic engines but use banks of Li poly batteries to power them which cost a
fortune.

I would imagine that the oomph required to successfully feed a bank of cylinders in a car engine at full chat (and maintain positive pressure) is a
bit more than that required to push a lightweight model aircraft?

I think Paul was just suggesting that 3 phase 12v applications do exist.
The larger model motors can produce an impressive amount of power for their size however; 600Watts (0.8hp) are not uncommon.
Some typical performance charts here. Current consumption is predictably dire, 360 Amps at 400cfm
and 0.5psi boost. Still, on a smallish engine it would actually manage a few psi which make a measurable difference compared to the pathetic computer
fan based jokes on ebay. The current consumption is why these things simply can't be run continuously.

my guess is a novak hvmax, the wires are definatly the same colours and in the same sequence, in which case they push out around 4hp running on 14.4
volts dc

Thinking out loud ..........
4 of those, 1 per wheel, 16hp ....... that would make one hell of a little buggy.
in fact 2 just driving the rear wheels would be a cool kids toy.
Actually, how many HP do mopeds have? I thought it was around 5 ...... two, in a little buggy (one to offset the weight in batteries) and you've
got a little city zero emissions bike).
