Electric Turbo Tested

[maddogmorg]

if its powered by the engine or electrical system in the car/bike it takes out more power than it gives

'eh? so how do belt driven superchargers work?

And aren't the electrical superchargers a problem as they require a lot more power than a standard alternator/battery can produce, so the kits use a small fan which doesn't produce anywhere near enough energy to actually increase power?

Running a petrol driven supercharger, independent of the engine could give some very impressive results i'd of thought, with constant boost at all engine rev range and the ability to reduce it for more economical driving so not constant full power. Though adds weight, complexity and takes up space.

The theory is sound as exhaust powered turbos and supercharges both take power away from the engine it's just they allow the engine to produce more than they take.

An electric super charger works as shown in the original post except electric fans use stupid amounts of power which most car electrical systems can't cope with hence why the ones they sell on the Internet are pointless and useless, a good leaf blower is gonna need about 2Kw of power which is about 160+ Amps off a car battery at 12volts, about the same as your starter motor under full load.

Conventional forced charging works because the air/fuel mix is changed to the explosion is more powerful. To make that more powerful explosion you you need to use a little power.

The problem with using an electric one is efficiency the drag on the alternator (if it was able to output enough current) would be more than that of a well designed supercharger.

because they are super chargers. wont work if you run a leaf blower off a belt

i'll just buy a really long extension lead.

Turbos and superchargers are specifically designed to produce high flow rates at high pressures.

The average electric fan can not do this, they tend to do one or the other not both so are useless for forced induction, especially on diesels as they tend to run much higher boost levels compared to petrol cars.

But bolt on electric kits are on their way.

.

belt driven supercharges drain more power than they give back above certain rpms. There simply parasitic.

Electric charges are a product to get money from people for nothing. They are simply not able to create good enough pressure (if any at all). I am sure that you could make a good working electric supercharger but its cost would exceed standard supercharger or turbo multiple times.

you best hope the dangerous brothers don't find you one of these

Just read through that link and what car battery or alternator can put out 350amps!! Gonna need some 0awg wire just to power it!

Horsepower ratings for typical starter motors here:

http://www.lucas-tvs...ducts/star.html

Multiply the hp figure by 80 to get a rough current on a 12 volt system (this accounts for motor inefficiency).

A typical diesel engine with normal starter gearing requires about 1/20th the engine power in order to start it.

For example, a 50 hp engine needs about 2.5hp (200 amps at 12 volt) to start it.

So my 115bhp Multiwagon would require in excess of 400amps to start the car(if I've done my the maths correctly).

While the car is easily able to produce this amount of power for the 2 or 3 seconds its takes for the car to start I'm not sure how the cars electrical system would cope with a huge 350amp surge everytime I put my foot on the accelerator. Some newer cars cut the engine when the car comes to a stop and automatically restart it when the accelerator is pressed. This must drain a lot of power but they seem to cope ok so who knows it may be possible one day.

Yes an electric turbo does increase engine performance but at what cost?

BMW use a twin turbo setup, one large and one small turbo. Small turbo for producing power at low engine rpm. Perhaps this electric turbo could be used in a similar setup on future cars, small electric turbo for low rpm power?

Look on the bright side, if electric turbos are ever used as standard all the 0awg wire will increase its scrap value ...

Im pretty sure there is already an electric turbo'd production car out there

I think its a nissan or something

when you want some more power - it has electric motors that spin the turbo's up sooner and faster to give a boost

i think i saw it on topgear....

I've looked but been unable to find this nissa electric turbo car. Anyone else heard of it?

 

[RuSZ]

Not sure it's a proper electric turbo, more an Motor Assisted Turbo, because it uses the motor to spin up the existing turbo.

An electric turbo would work in a similar fashion to a supercharger and run indepentaly from the exhaust gasses (used to spool a turbo)

If we're thinking of Electric Assisted Turbos;
