"Off the Wall" Idea for an Electric Supercharger

OK, we've seen the so called "electric superchargers" that are really just a boat bilge blower with a ducted fan billed as "electric superchargers."

But, now with electric radiator fans becoming more and more efficient as they get smaller and smaller, what about taking a small electric radiator fan and stuffing it up within an "in-hood" air cleaner unit similar to the L88 or right within the air filter housing itself?

1,000 CFM of carb flow will easily support 500 hp. Here is a radiator fan that is only 8" in diameter and 2.25" thick and moves as much as 2,100 CFM.  Other compact designs are also available in higher flow applications.

This is small enough such that it could easily be mounted within the confines of the air filter and suck external air from the cowl (ala L88), or even a pleated air filter top and with internal ducting, perimeter, ramming it down the carb or throttle body.

With solid state speed controllers readily available, a throttle position sensor could be used to match fan speed with engine RPM and allow varying degrees of "boost." Of course the carb or fuel injection unit would have to be prepared similar to a "blow through" supercharger unit and additional fuel pressure that tracks boost would be required.

This is just too easy and cheap to implement, so what's wrong with this idea?  It sure would be nice to have a patent on a "drop in" supercharger that fits right in the air cleaner housing.  

 

keep us posted on the progress of research and development of this fine idea

That's 2,100cfm of unrestricted, large area flow.  Restricting the flow (smaller cross sectional area) will significantly drop the cfm rating of the fan.

i was hoping to see how much boost pressure the fan would create in the manifold

That's right.  The flow at any kind of meaningful pressure ratio would be minimal.  The density ratio might even be LESS than with no fan at all.

If dyno time didn't cost so much, it'd be fun to hook one up to the top one of those K&N full-flow air cleaner tops and see if there's any measurable h.p.

thanks guys...you've used your fans to remove the smoke i was blowin'

I'll look for it later tonight but there is a video of EFI guys on a chassis dyno that hooked a large gas powered leaf blower to a SBC, it added about 2.5Hp to the engine, or roughly half the 5Hp rating of the leaf blower.

OK..., so maybe the guy with the leaf blower was on to something but the implementation was wrong.

The guy with the leaf blower is reported as expending 5 hp to get a 2.5 hp increase.  But what if he was running the leaf blower (or somenting equivelent) into a turbocharger where the exhaust would be plugged in?  Certainly turbos put out far more power than they consume.  

so instead of running a small gas motor (leaf blower) to power the turbo you're suggesting turning the stock iron manifold in a manner so the turbo could be attached to it and let the motor in the car will run it

or do you mean to run the leaf blower to power the turbo?

Run the leaf blower/fan/whatever to power the turbo.  

i vote for a custom block.. with 8 inch pistons on one side.. and 4 inch pistons on the other...  using the 8 inch pistons to compress the air for the 4 inch pistons...    sort of a modified triple expansion motor reduced by one third and run backward..  















and if you believe that.. i have a good deal on a bridge for you...  

does that use standard or reverse rotation water pump?

For fans, the power required works something like this:

Shaft h.p. = (5.2) X (in. water) X (cu. ft/min) / (33,000 X efficiency).

"In. water" is pressure.  The radiator barely causes a pressure difference because all you need is the mass flow across a radiator.  To maintain a minimal streetwise boost of 6+ psi, you would need a centrifugal blower, which is really just a fan anyway.

So, take a Procharger head and hook a batshit motor up to it and you're ready to go.  

Hey, you can't do that.
That patent is mine.
If you do that I will demand you.
