Outer Limits 4x4 Board

i was looking at purchasing an electric turbo for my hilux. its a 2lt 4 cyl petrol. to install you don't need any computers or anything. it simply mounts before your intake and it runs off your battery at a constant boost.
what are your comments on this?

I haven ever heard of these.

Dare I say that they sound like a hiclone type product - but expensive.

Have you been able to talk to anyone who has one?

if you look at the dyno sheets for these products the power gains are not much better off than simply installing a K&N type pod filter.

They draw lots of current, will your stock hilux alternator keep up with the lights, wipers, stereo, heater and this thing running?

Is your Hilux carbied? if so howwill it run with forced induction. Carbies like to have air sucked through them, not blown through them.

That statement is incorrect, from a physics point of view sucking something through and blowing something through is really the same thing born out of a pressure differece between 2 points.
You end up with the same result.

What is critical in a carby is that the pressure on the fuel in float chamber is the SAME as the air pressure that is on top of the carby. The easiest way to acheive this is to "box in" the carby if you have forced induction.

As for the electric chargers and any "hy-clone" style product that are sold aftermarket you must consider this...

"If its that great, why arent car manufactures who spend millions a year to gain better power/economy fitting these?"

And then you realise its all just a stupid gimmick.

About The Electric Turbo / Electric Superchargers
The eTurbocharger.com Electric Turbo / Electric Supercharger has been developed to install on any vehicle just as most aftermarket high performance cold air intakes are installed. The only difference is our install connects to your vehicles battery and a momentary push button switch is either installed on your vehicles throttle or somewhere within your vehicles cabin. The electric turbo will operate whenever the push button is depressed. Many people ask why the supercharger dont operate constantly under all throttle conditions. The main reason is constant operation would drain a significant amount of your vehicles battery and some stock alternators will not be able to keep up with the extra electrical usage. Our install basically works like most nitrous oxide systems. At wide open throttle, or whenever the push button is depressed you will receive an immediate a full boost until you release the push button. The feeling of the extra boost is immediately noticeable and will leave you quite impressed!

I read this off there website. Sounds funny to me

Some how that electric turbo looks dodgy to me.

Why don't you just buy a normal turbo? Tried and tested. I take it your engin eis the 22R...easily find a turbo at the chop shop.

because if you add some extra plumbing, you can do you hair at the same time.

they are a waste of time!

dont buy one, they run at about 2-3 psi and the difference is barely noticeable as the alternator is working a lot harder to run the thing and using more flywheel HP, so you dont really gain bugger all

Waste of f'ing time and money

i recon you should buy 2.

install the second in the exhaust but wire it in backwards so it sucks the burnt gas out of the combustion chambers

I absolutely laugh my arse of at these hair-brain ideas, just the conversion losses between an alternator to make the 12v then a 12v motor to drive the fan, I don't think they know how big a @10kw 12v electric motor is, that is about the equivalent air pump to produce this minor increase in air pressure, let alone the 10+psi needed to make a difference.
To put it simply a diesel 2.8 litre 4 cylinder motor needs @ 1.4 litres of air per revolution, so even at the lowest idle of 600 rpm, that is 14 litres a second, just stick your hand on the intake of a diesel you will see for yourself (after you get back from casualty ) that is a lot of air.
Check out carbibles.com, they clear the crap on lots of myths out there, hyclones, slick50, batteries going flat on concrete etc, I like to see new inventions, but I use basic chemisstry and physics first B4 believing advertising crap

Fully G*A*Y.

just buy one and then come back here and tell us if tis any good or not

U may be onto something there.

Ebay

While we are on the subject of silly idea's.....

How about the concept of using compressed air in a tank with a regulator to push a few psi into the engine when you trigger it. Maybe a switch under the accelerator or whatever. Anwyays, back on the air side of things what you reckon? I can see one major drama being any amount of water in the system so you'd need very good filtration.

You wouldn't have an air tank big enough to make a difference.

There are compressed air powered engines out there that work real good.
They use carbon fibre air tanks under the full length of the car.

The electric turbo thing was tried on motorbikes a few years ago and from reports made stuff all differance.
So in other words they are shit and don't work

So you're saying you need a big burst of air not just high psi coming out of a small nozzle?

what size intercooler car you run with them??

That's it. Look at a 'real' turbo - it's got a huge outlet, but might only produce 6psi, as opposed to a comressed air hose, producing plenty of pressure out of a tiny outlet. Someone mentioned you need 14L per second? Well a big tank in a 4wd is 20L, and i can't see that being emptied in a second!

Even if you could get enough air in there quickly enough, it's not going to do much if your running a standard tune.

I have to reply - it's annoying me.

To start with. Boost/pressure is a result of resistance to flow. Any turbo can make 100+ psi, just simply block the outlet. The way an engine is 'boosted' is the fact that the turbo can supply more air than the engine can use (at certain rpm) which is why boost drops off higher in the rev range, ie using more air, less resistance to flow.

Let's take a car running 14.7psi (1atm/bar). If the N/A engine uses 1.4L/rev then @2500rpm that's 3500L/m (124cfm) of air then the same engine turbo'd @14.7psi would need 7000L/m (248cfm) of air.

I can't see how a small electric thing like that would be able to supply 'more' than 124cfm to make 'any' sort of boost at what is resonable revs for a deisel, let alone a petrol.

In the famous words from the castle - "tell him he's dreamin!"

Yep,

Having read their thru their web site, I was getting flashbacks to the blower on Mad Max's XB coupe with the on/off switch (also a gimmick!), save your cash and if you still want a turbo, get a real one, not a pretend one!

If it worked, the water may not be a problem, People do use water injection systems.
