KKK K26 Turbo.....that's electric?!? MOve over ERam!

K, what's this all about?

electric supercharger.

here's one guy's take on claims versus actuals (albeit for a different unit).

[beepbeep]

Those wires are too thin to transmit any serious amperage...

[Amac]

So this thing run at full boost all the time?
I guess you could have a on-off switch.
Maybe you could use it to pre boost a real
turbo?
Don't think it's the real thing, looks like a
homemade unit.

Here's an article about a system that Visteon developed a few years ago for use with small displacement motors:

Can't believe noone here knows what this thing is....lol

KKK has always been a quality name in the turbo world....so what gives? Is it homemade? Or some type of blower for equipment in other industries that they're involved in...?

[tsuter]

Electric drive motor uses an old "slide wire" resistor coupled to the throttle linkage so that the more throttle you open, the faster it spins. That compressors good for 5-6 psi at 80,000RPM
Better go out and get one quick before they're all gone.
Right after you put an oil cooler in your turbo tail.

i thought i just told you what it was. do a google search for "electric supercharger" if you want more info.

I think I'll hook it up to the heat exchangers. "Are you warm now?"

Seems like you'd need a beefier motor to spin that thing to 10,000rpms (or whatever it is). Think about the size of a 1.5 hp starter motor. What kind of juice would be required to generate high RPMs against resistance? Um hello! But even if the wires were thicker you can't get something for nothing....you would also need a fatty battery and alternator to boot.

What do you think the German "instructions" say?

Probably "you are an idiot for buying this on ebay. Hans and I took a junk 944 turbo and bolted on this used electric motor. If your luck it it spin 900 rpm when connected to a 12 volt battery. We figured that some fast and furious type would buy this piece of junk."

"It looks brand new? and just may be. "

Bid with confidence

I recall seeing this in a magazine a little while ago.

Let's put it this way. Belt driven superchargers use quite a bit of HP to turn, in fact the bigger ones have been know to snap the snout off of cranks. I seriously doubt that motor has the power to spin that thing fast enough under load and if it did you'd probably need a huge secondary alternator to power it so what's the point, just install a "real" supercharger.

[marksportcts]

Yep, it needs either several smaller batteries such as the Hawker/Oddessy, or 2 large batteries that weigh 55lbs each.

Are you sure?
I understand that sometimes, there is underlying aversion against "the new stuff".


heh-heh

read "Corky Bell Max Boost".......it is in ez terms......you need amin of 10 hp just to start some action......that would be one big motor....

I've done the math on these electric turbo/superchargers.

To get 7psi pressure at 300CFM with a 70% eff compressor and 70% eff electric motor you need about 17Hp (~12600 Watts).

To get 12600Watts from a 12v battery you need 1000 amps!! Sure lead acid batteries can deliver this, but only for a very short period of time.

At less boost (3psi) you need about 8Hp (~6000Watts). This is about 500amps from 12v. With convenstional car batteries you could probably run at this boost for a couple of minutes.

3psi boost with no exhaust backpressure and zero lag is very appealing. Probably good for 20% increase in Hp. Also no messing with exhaust, mufflers, oil feeds, etc makes the concept very attractive.

I've given this concept much thought myself and may convert one of my spare turbo compressors into such a unit.

Once battery technology improves, this idea will become more practicle.
