Those "electric turbo boost super chargers +50hp and +60ft/lbs" on ebay, we have all seen them right? My friend had one of these sitting around and I use it currently to hold my air filter cone to my intake tube. It wasn't until recently that I even actually wired it up. I tried using it in just about every possible fashion but I never see my vacuum go above 0. I didn't really expect much.. I was just sort of curious if I could modify it to even get any boost out of it at all just as an experiment. It runs off 12v and I was almost thinking if I ran it on 24v it would spin faster? I don't have any hopes of this thing performing anywhere near real forced induction. I like to tinker around with silly frivolous things such as this just to prove a point to myself. How would you go about getting 1 lb of boost out of a blower motor?

It wont happen

It's people like you who inspire me to do things like this.

Drop the plastic turbo
Buy the reAl deal.... Lol

Those things are usually made to flow cold air to the intake
Not to boost

Consider this.

A real turbocharger spins at 100,000rpms +.

Those plastic ones, max 25,000.

Also, blowing air and compressing air are two very different things. Fin design and makeup are very important to do this.

Noble intentions, but a total waste of time.

Make your own with a mamba monster 8th scale electric rc motor and use a 6cell lipo battery to power it on a momentary switch. That should blow a good amount of air in. im pretty sure you can get 100,000 rpm out of it.

That's funny. The first idea that popped into my mind was to use a brushless motor.

NA James

It could work. And if it could be put on a gear/trans from like a losi 8ight-e it could spin at different speeds and a propeller from something like a turbo.

I would wonder how much current you would need to make any good amount of boost.
Check this link out I just glanced over it looks like 3 starter motors turning a supercharger.

have a nice day

thats funny the idea once crossed my mind a long time ago lol

Try a leaf blower lol

BetterBtuning

MAKE SURE THE LEAF BLOWER DOSNT HAVE STUFF CLOGGED IN IT OTHERWISE YOU HAVE TO RIP APART THE MOTOR AFTER SAID "AWESOME" IDEA CAUSES IT TO DROP A CYLINDER !!!!!!!!!!





SINCERELY

Haha that's awesome

rich7777

Why don't you just wire up a hair dryer to the battery and use that ?

Organization

lol i was thinking along the same lines

two brushless motors turning a real turbocharger impeller thru a gearbox to either reduce or increase rpms (final drive) and power them using two motor speed controllers which you can use to controller the rpms boost ect

this is just wild thinking

phunhaus

Rotrex?

Traxxas uses a 2 engine setup and turbos spin easier then the 3 differentials on a rc truck. Hook a spur gear up to the exhaust side and spin it to 100,000+ rpm with some 6cell lipo batteries and see if it works. Should be to custom

This ^^

Why is this thread still open?

I've considered this as well.
It seems to be a fairly logical idea to consider if you look at the path centrifugal superchargers follow.
Obviously a centrifugal supercharger operates a compressor wheel on the same principle as a turbo charger, however has a different means of propulsion.
Where as a supercharger uses a belt drive, and gear reduction system driven by an engine to make boost, why couldn't a powerful DC motor turn over a supercharger pulley like an engine could.
What I have thought as a possible option would be for the given electric motor to always spin at a set rpm.
Consider a AC motor from your typical air compressor.
They spin at 3450 rpms.
Adjusting that speed effectively to accommodate for throttle position, load and adjust the boost being delivered seems just too complicated to me.
Why not plumb in a "wastegate" downstream connected to manifold vacuum to either bleed off (at closed throttle) or deliver full boost (under load)
Just my two cents, and I doubt anything on ebay is anywhere near being a useful investment, but I credit the next for being brave and bringing up some new discussion.

Natural Aspirations

It takes 30,574 watts (2548 Amps @ 12v) to produce 41hp!!!

dglassmyer

I would like to see empirical evidence that converts thermal expansion required to power a turbocharger into a 41 hp figure.

i built a junk yard turbo kit for like 400 bucks, lipo batteries and rc motors sounds like it would cost more than that ... but that would be a first, and if it worked you would deff have my respect

Organization

you could use the car's electrical system for the power source instead of adding extra batteries, and you could even add a cap to limit the shock to the battery during initial start up along with the electric motor speed controllers

you get the ideal those rc motors are powerful but i think theres some better brushless motors out there with more grunt

i was seriously about to post the same thing

throw a couple lipos at it, and let it eat. HAHAHA
