Electric Supercharger?! (adaptable for fuel economy?)

by who; most of what i've read on the web leads to mixed results

E-Ram Electric Supercharger Testing

this guy thinks it produces additional power. Not much and it's still in the realm of error for both dyno and operators.

t vago's page suggests that it's about as useful as a cold air intake or larger/different throttle body.

ps. if you don't test something more than once; the subject of error over takes what might be good data. case in point the fuel logs

Sorry, I don't have the information any more. I found a link to it through one of the CRX-related BBSes, either the crxresource one or the crxcommunity one. This was quite a few years ago, though.

Hey, if you want to spend $300 to get a shiny new bilge fan, and test it over and over and over and over and over again, be my guest.

Post results when you do!

ps. 15hp=12kW

As said, F=MA. 10,000 rpm free-spinning is not quite the same as 10,000 rpm under load. A regular turbocharger will be spinning at 60-80,000 rpm under load... accelerating... shovelling air into the engine.

I have no doubt that 7 kW of motor is enough to net some positive pressure, but again, I doubt you'll get more than 5-6 psi on your 4 liter motor... looking back... maybe just 4-5 psi. Would be an interesting project... attach it to a supercharger... see how much boost it makes compared to hooking the same charger up to the belts, and how much power that boost will make.

I remember the e-charger! Bilge pumps, too! I used to search for stuff for my Prelude and I laughed at everything but OEM parts. I do not know about now, but the e-charger said that it removed 0.5 PSI of vacuum losses (or something) and provided the same amount of actual boost.

I remember someone doing the math of how much air an engine pulls in on its own and linked the manufacturer's specifications on the bilge pumps, not the fantastically unrealistic numbers on eBay. eRacing may make a bilge pump, but at least their claim that it would not fall apart and fly into your engine sounded credible.

Okay, I am going to find that leaf blower engine.

How bout you find a gas leaf blower, put on some wheels and a seat, steer by leaning and make a thread showing the complete build,lol.

No, what you need to do is build a special go-kart with a two-inch steel shield behind you and then drop live grenades!

Probably would be wise to install some sort of shock absorbing mechanism between the go-kart and the shield. One could carry a bunch of grenades in the cart, too, and have a ejecting mechanism to shoot them, one at a time, at a spot right behind the shield. Timing the grenade explosions could be tricky, though.

You'd always want an SUV or pickup behind you otherwise much of the blast energy will be wasted to the rear and not propel you forward as much as you want.
