electronic supercharger

[jvs8864]

hey everyone, im brand new to the forum but have personal experience with these electronic super chargers..
just a little info on why they dont work, a normal turbo has a blade that increases RPM with the engine (when your engine needs more air, your turbo blades spin faster)...
but, with an elextric one, the "induction" is only at one RPM, whatever the motor is set to run at, so, there is a very miniscule amount of power gain, and its at a very small RPM window...

ive installed these and tuned them for people who feel its not a wate of money, hope this helped!!- feel free to ask for more info.

the speed of the blade has little to do with it. you could make a blade turn a measly 300RPM and still move 1500+ CFM...it would just have to be huge.

the problem with all the current "electric superchargers" on the market is the lack of power. they all use a puny heater-blower-motor sized motor that couldnt draw more than 100 watts or so...when even a small displacement engine would require closer to 1500 watts in order to move sufficient CFM for even a small boost (2-3 PSI). this means something on the order of a large starter motor, not to mention most vehicles would need upgraded charging systems to support a continuous 100+ amp draw.

the second problem with electric super chargers is impeller efficiency. those little plastic housings and blades are not designed with close enough tolerances to build any real pressure...meaning most of the energy is wasted past the blades.

a real electric supercharger would be a large, commercial starter motor out of a heavy machine, driving the compressor side of a commercial turbocharger.

the problem with the thomas knight setup is it runs on a second battery bank....which means your hauling around 200lbs of extra battery weight all the time, your limited in how long you can use your boost, and you need to charge the battery bank for several hours after every run.

for the downfalls to the TK system, a guy might as well run NOS.

All they are is a bilge fan from a boat... A turbo or charger compresses the air through the inlet turbine housing by forcing it through a smaller dia pipe, with a carefully designed impeller.

I high doubt it adds any boost at all. In fact I am will to put money on that it prob restricts air flow at higher rpm.

I am not bashing anyone on here, but how come everyone who says they work never has a before and after dyno sheet to back it up.

I'll leave the "Supercharger" to the rice boys.... I'm sticking to 10hp+ stickers!

Its not that hard to go with a real turbo

I have heard of some of the cheaper "electric supercharger" bilge pump ones have plastic blades. Also if your engine draws enough air, this thing will be a restriction and the engine can possibly make the blades spin faster then they are supposed to leading to failure of the blades which = junk in your engine.

i wanted to know if anyone has seen those electronic superchargers that come off your intake and have a cone filter on the end they are suposed to give you a 3 psi boost and wonderd if anyone has one or knows anything about them

I push 5 psi through my Eaton blower using an oversized pulley. The only thing a hair drier is going to do for your truck is draw amps from your alternator and likely COST you power. If you want a blower, do it right. Stay away from the hair driers!
