ets electric supercharger

[BIG BIMMA]

hi guys , has anyone got any info on , or used an electric supercharger ?
found one by a company called ETS , WANT TO KNOW , ANY GOOD , JUNK OR NOT .
I HAVE A E36 328I COUPE WITH SCORPION EXZAUST,DAVEF KIT AND M50 MANIFOLD .
ALSO HAVE A BBTB COMING SOON AND WANT TO FORCE FEED IT .
ANY INFO OR SUGGESTIONS WOULD BE APPRECIATED .
THANKS

NEED MORE SPEED FOR MARHAM

It's yet another of these toys sold to the gullible.

Agreed - elctric "superchargers" fall into the highest order of snake oil! If your induction system is standard, then fit a good freeflowing air filter, that has ducted cold air feeding it.

Buy an m3 for a quicker Marham day.

Every time I see on of these post I remember something you one wrote... along the lines of... "yes, they are highly effective - at parting a fool and his money."

Even if the electric supercharger did create enough pressure - and i'm not saying they dont - its not just a bolt on mod. You would needt to alter your fueling and ignition timing to take advantage of the extra boost.

thats what i am trying to do , i want to force feed the induction kit to work in conjunction with the bbtb and uprated fuel pump so that i can get more air and fuel in before i get it remapped to maximise the engine power across the whole rev range .
i know that the so called ELECTRIC SUPERCHARGER is a gimmick but it can be used to boost engine power
MORE AIR + MORE FUEL=MORE POWER

Yes it can be used to increase power, on a lawn mower. The problem isn't that the goal of supercharging is wrong, it's that these little gizmos are so woefully under powered that they will struggle to overcome the drag of the motor and fans in the air stream let alone have any net benefit. More likely when fitted to any decently powerful engine they will act as a net restrictor. Worst case scenario is that after having the engine sucking hard on them for a while the blades will come off the fan. It's downstream of the air filter of course so nothing between that little cheap and nasty (OK, expensive and nasty) fan and a few thousand pounds of engine damage.

To put it into context, the air is coming through the air intake at a substantial fraction of the speed of sound in many cases. Adding any useful compression to air at those speeds takes a LOT of power, it'll depend on the engine capacity but as a rough order of magnitude let's say we need 1000W of mechanical power per 1 psi boost. If your motor is 75% efficient and your fan is 75% efficient and it's powered by a 12V supply that means the motor needs to draw around 125Amps for 1 psi of boost. You need some pretty hefty wiring to carry that, and a motor big enough to handle that much power is a big old lump. This is just for a 1 PSI boost, which is only a 6% gain and hardly worth shouting about if you're trying to tune your engine. You can probably get more impressive gains by changing your air filter. Curiously, the motors that you get in these things fit neatly inside the ducting without obstructing the air flow. Is this because they're made using exotic 'rare earth' magnets and superconducting coils, or perhaps because they're just weedy little motors that sit there making buzzing sounds while you convince yourself that it's doing some good.

Or, to put it another way:

Waste. Of. Money.

Then again there's always a TVR... muscle and curves... big V8... no need to strap any toys on...

[thetrash]

I have one of these on my car to deliver 8/9 psi on a 2 litre engine and it's pretty heavy



This runs off the crank pulley and makes a hell of a differance. You can supercharge BMWs with rotrex superchargers(I think)but for what it would cost you'd be able to buy an e46 M3

There ain't no replacement for displacement.
LS7 v F430 engine

Nice explanation if the different types here. One guy is running one of these positive displacement Harrops...



@ 12psi and getting over 500bhp at the wheels.

Mine uses one of these:

It's a big heavy thing that takes several BHP off the crank. The thought of replacing it with a little electric fan is quite comical.

To extract more power, you have to put something into the equation and, aside from engine-driven supercharging or exhaust-driven turbocharging, there's simply no other way of compressing enough air to get more in. So, unless bolting one of those is on the cards, go for the freest flowing induction kit you can get, so that the volume of cold air that the engine can gulp in is not limited in any way by the filter or the inlet tract. Other than that, without mods involving remapping the ignition and fuel, or more significant mods such as raising the rev limit with the consequent need to beef up the engine internals, about the only other area is the fuel. Using octane boosters might give you a little more, but beware the ones that say raise the octane rating by 2 or 3 points - reading the small print can reveal that they mean raising it by 0.1, 0.2 or 0.3 points, not by a whole 1 2 or 3 points. A petrol mix with neat toluene (about 2-5% of the latter) will increase the octane rating by far more than the octane boosters, buit is difficult to get hold of and is nasty stuff. Then there's a nitrous kit.....

But in all of that, increased power will increase the acceleration rate, but unless the rev limt or gearing is changed (whether through gearbox, final drive ratio or tyre size changes or all three) the top speed will remain the same.....

There was a thread recently that attached an electric leaf blower to a pickup engine - now THAT made a difference ..... but you would need a long extension lead

I am constantly amazed how these things are sold on eBay - can anyone really be that naive? It is right up there with the so-called remap modules that richen your mixture (actually a resistor that costs 10p) and boast a 30bhp increase ...... in your dreams.

Save your money - it is a load of twoddle.

that's nothing, we had a guy on here recently who believed that folding down the rear seats made his car faster
