Ebay Superchargers

Hey Subadudes,

I have just been looking at those superchargers that you can buy on ebay (force flow etc) and I am wondering how good they are and if anyone has got one on their car?

Cheers,
Corax.

^^^WHS The only semi decent ones only run for a few minutes as they drain the battery really fast and price wise are in the 1000's. And forget hairdryer power, think leafblower. I think this has been discussed before?

do it! will go heaps fast

Not even possible.
That fan could only produce enough air to make positive pressure at idle, even at cruising throttle (5-10%) open it would cause a restriction to the intake.
How big are the wires to the fan? Just normal figure 8 cable rated at maybe 5 amps max

Even if it was to able to supply just 1psi at full throttle , it would have to use over 100A from the cars electrical system. And the engine has to supply the power to run the alternator. With all the energy lost due to friction/heat ect, you still loose power and fuel efficiency.

Thats a mechanical supercharger

If you are refering to this product Subaru Supercharger Turbo for Impreza Liberty Forrester its even worse than i thought. It doesnt even have a motor, its just some blades that freespin.
This seller should be prosecuted for fraud!!!

This is the electric version, which is a fan similar to what is in the heater blower but smaller Subaru Supercharger Turbo Impreza Liberty Forester Outb Yes its electic, but the motor on it is small, which means it cant spin fast enough to produce enough aur for WOT acceleration.

I have seen a real electric supercharger and the motor on it was like a starter motor, coupled to a step-up gearbox to to increase the output speed, and the wiring was as thick as your finger and it needed 3 extra deep cycle batteries to cope with the current draw

That's a hard call to make. The add clearly states it is in free spin so the buyer isn't being lied to in that regard. It seems they are pushing the turbine action of the vanes as being the catalyst for the benefits it supposedly provides. Its basically the same as a Hyclone except it moves.

The electrics aren't worth the effort.

they say up to 7hp gain, i'm not sure how you can dependably measure that anyway, that much variation can occur by dynoing at different times.

Hey Storm, get one

Oh,I see:) I mean 7hp, pfft, but with 10 of them:D:D:D that't be a thundering sti

Hi Subadudes,

Thanks for the replies, would put a link in but dont know how. The One I was looking at was the force flow x4. they reckon they can get 43000rpm out of one of these things and that it can add 7-10% increase in power. They also have got a you-tube video on the site to back up their claims. Worth a watch to see what you all think!
Still, good to know that they do bugger all! You guys just saved me $500.

Cheers,
Corax.

Theoretically the increase in hp would come from the veins creating a vortex in the air flow, as I said it looks like a hyclone except it spins where the hyclone doesn't. The engines vacuum would actually get the thing spinning before the air forces its way into it would get it spinning. Its the exact same concept as the kids fans that you can buy at the Royal Easter Show and town carnivals/shows. Kid runs along and the fan spins, a breeze blows and the fan spins, put it in front of an electric fan it will spin.

That's just a complete wank.

Toyota have been putting directional veins in the air intake for years, its nothing new.

Well of course, the whole thing is a wank.......
but why'd they write that in their add? I suppose by saying its a customer testimonal, gets them off the hook?

Those mob just depend on ignorant people just buying it, instead of well, people saying "I'm interested in my car, and learning more, so join a enthusiasts forum and learn more....and ask questions"

If you feel you are fully informed, then go ahead and buy the damn thing.

And now I'd like to see other confirmation that Toyota is "using directional veins in the air intake for year" and is it really the same thing.....not just hearsay.

Having something like this before the throttle body and plenum is pointless to start with, a half closed throttle and an intake plenum is gonna mess up any vortex before it gets to the combustion chamber anyway.

The only way it would work would be to have something swirl the air just before the head, Subaru's TGV's (Tumble Gererator Valves) anybody????

Toyota probably has a similar device

You can suppose that if you want, to me it seems as though they have just put it in hoping idiots believe it.

Don't you just love living in the free world! Its not illegal to be a complete and utter gullible idiot you know. Of course they work on peoples ignorance. If you lived in ancient Greece you'd be killed for doing such a thing (the term Draconian refers to Draco's laws which basically gave the death penalty for the slightest misdemeanor. Infact just being an idiot could get you in trouble even if you did nothing wrong

). You may well note however that the OP did ask a question on a forum cause he does care about his car.

I hope your not getting snotty with me. I merely pointed out that fraud is a hard call to make with regards to the free spin which I thought Suparoo was referring to.

Take a look at the air cleaner assembly of an HJ or FJ 60 or 75 series If the owner has kept it all intact you will see a tube that goes into the inner guard. That tube slides into another tube that is bolted to the guard. At the end of the first tube where it slide into the one bolted to the guard are directional vanes just like a hyclone. If you don't believe me you are most welcome to come to Tamworth and personally take a look at mine.

Not entirely accurate. Air will flow through a restriction and speed up as it goes through. Air will always take the path of least restriction so it flows around the throttle plates. Carburetor venturis and idle jets work on this principle.

Not if your previous theory is correct because as soon as the intake valve shuts your swirl stops dead.

read my previous post to see what Toyota has been doing.

Yes, but flowing around the throttle is gonna mess up any spiralling of the air.

Storm wrote: Not if your previous theory is correct because as soon as the intake valve shuts your swirl stops dead.

But the idea is to turbulate the air as it flows past the injector and make a consistent air/fuel mix. They only operate at idle and cruise to give better emissions and fuel economy. Read the latest EJ25 FSM, it explains why they are there.

I thought you meant modern Toyotas.

Is the device in your landcruiser before the air cleaner? Cos i have seen on tractors/earthmoving equipment ect. they have devices to make the air spin and separate the dirt from the air before the air cleaner.
