Electric SuperChargers Mythbusted
video description
I see no reason why you couldn't get a high power brushless DC motor, cut a turbocharger in half leaving only the compressor side, mate the motor to the compressor, and thus have a very seriously powerful and programmable air compressor. Finding an electric motor that does 150, 000rpm without gearing is not trivial but they do exist.

That first toy probably introduced a restriction. The turbine blades made from beverage cans was a visual give away of impending failure.
Now, with 2 blowers you need a plenum a bit bigger than a PVC T piece. Highly likely that there was airflow stall in one or both leaf blowers.
Common problem in air feed systems.
Try again with 2 holes in the filter lid.
Get a bit scientific fellas, fit a simple manometer tube to see/measure what's going on.
If you don't add fuel you won't get more power by just blowing, at best you are reducing induction losses. Worse case is your blowers are choking the inlet.
More science with the fun please.

Still, considering that I didn't see you pull the air filter out, I can't help but wonder if you would have seen a whole other pony of power if you had checked that. After playing with a lot of 200 to 500 dollar cars, replacing the air filter is generally one of the first 3 things on the list when I get an old beater. Spark plugs, air, check compression & add Engine Restore if needed (for 3 & 4 cylinder engines, anyway) are usually the first things that make a noticeable difference.
How do we know you wouldn't have made a whole other KW or 2 from those leaf blowers if we didn't see you check the air filter?

I remember my mom had a 1L, 3 cylinder Geo Metro and later had aftermarket A/C put in. There were some long mountain inclines where you couldn't get it past 45MPH if you had 4 passengers. That requires you to put your hazard lights on in the U. S, on the interstate. It was a manual transmission. Trying to start at a stoplight on an incline with 4 passengers & the A/C on was usually impossible. You'd have to switch the A/C off & still ride the clutch to get the thing moving.
50MPG is nice & all but not when you can't travel beyond a snails pace. Get a bike if you need that kind of gas mileage.

I think all of you make wrong tests. In first, from experience, you can't measure on dyno everything, some things can fill and measure just in riding a car. Second, you do test with external battery but her voltage is smaller than from car alternator. Third, your test car use negative pressure for working, and can't be boosted without some mechanical changes. Also, power will go higher after some time, like with other gadgets and additives. Some gadgets is really without effect, maybe this electric turbo also didn't working, but your tests not valid.

I supercharged my car for only 10. All you have to do is draw air from the front of the car and route it through to the air intake under the hood. The opening at the front of the car should be a minimum of 2 inches wide. Best of all, a supercharger like this requires no electrical power, switches or relays. The supercharger is activated as the car drives down the road. The faster you go, the greater the air pressure at the air intake box. You wouldn't believe the amount of air and air pressure at the air intake, when the car is moving at just 60mph.

Actually the CONCEPT of an electric supercharger is a good one - use electric power (basically from the alternator) to boost the air pressure going in to the cylinder. I think the problem with the one they tried was that the air pump was a pretty useless fan. Get a proper electric air pump and it would work great. They might also want to put it AFTER that enemic air cleaner.
I really don't know why auto mfrs go with turbo rather than electric or mechanical supercharging.

He's worried it's going to take too much power huh or make it I'm sorrywell you can't just boost an engine and think it's going to make maximum power right away you have to do a lot with the fuel system like bigger injectors and a bigger fuel pumpCourtney polishing excetera just throwing a turbo on there's going to get you some power but it's not going to blow your engine up unless it's already a piece of shitt to begin with and in that case you have no business boosting it

The only electric turbo I've seen that works is one that Cleetus McFarland tried out on a Chevy Cobalt. That actually gave a 5-6psi boost, which was a noticeable bump in power. Unfortunately, those systems are very bulky, and very expensive, coming in at about 2500, though it's a straight-up bolt-on system with a very simple install. I believe it's called the TorqAmp. If it wasn't so expensive, I'd consider one for my daily driver, just for the hell of it.
