See if you can put one on a spec miata race car, win your race and then pass tech for illegal performance mods. 1psi of net air flow change is 6% gain in density. I dont think that would be fair to anyone in the class, do you?

I'm a little weary about shoving something with blades in the intake tract. What if something clobbers it and the fan breaks throwing shards at the MAF and/or into the engine? I already had a hamburger wrapper, 6 ounces of pine needles and cigarettes sucked into there. At least there was a filter to stop it.

Thats why it is either, before the filter, (like mounted to the 928 air box) or after the filter. (filter mounted to it). I prefer to have it before the filter, then, it is a non issue if something happens. in 10 years of racing and street driving with it, I have had no issues.

Thanks Mark. I like being common

mark kibort

Hey, I didnt mean it like that!!!!!

If they would of thought about something simple as putting the fans inline before the filters parts never would of made it into the engine.

There is little about me that is common. I kinda liked thinking at least my thought process was common

Searched more on the EDF.Looks like it has been done and with a nice looking setup.Good for 10hp if you can get 4%?Hp is usually higher on small engines but says good for 5.0 liter and under motors.If 10hp from the fans and 10hp to 12hp area from the cold air 20hp overall is ok.Looks similar to Eram but in AU.
Draws 60amp from battery with 43,000rpm brushless motor.
Not sure on the x8 motor if it uses its own battery pack or runs off the car system.

Its crap, and doesnt work. we have done exhaustive dyno testing with the full range of fan impeller designes at 60amps and 12volts. basically, its a slightly more effective, traditional eram, at a higher price. You just cant get much more pressure and flow with that little input power. Plus, thats a patent infringment (on the patent of the axial flow design of an electric supercharger), and cant be sold in the USA.
the motor might be 43000rpm rated, but if it is spinning at that speed, there aint any pressure generated, nor flow, because the power is not there.

Mark,
will the new Eram be setup in the tube like that?I know patents have to be setup in every country to be protected so it couldn't be sold here and vise versa if that has a patent in AU then US models couldn't be sold there.Only way is to know someone to buy it out of the USA if you really wanted it.I am just looking at the setups to see how they are put together and that is what I was looking for.I would think the 24volt systems would be best like you say as they have more watts.

EDF's are for pu$$ys!

This is what a Mirage should look and sound like




and an A-10 (wonderful flight demo the guy does also....looks as real as it gets)

mark kibort

a little bottle of kerosine, a little turbine engine, and we could get some big pressure, problem is the heat it would generate, via the exhuast , which no intercooler could help. Or, it could drive a compressor, but then , why not just use a belt. electric makes more sense.

mark kibort

Yeah, we didnt go for a global patent, too expensive and too hard to enforce.
These guys were sellng on ebay and we shut that down.
I think we got a copy of the unit as well.
Yes, we wil have a similar configuraton, but it will be a heck of a lot more powerful. Their design uses a traditional edf impeller that is designed for high speed and not pressure. we have tried to blend the pressure we want with the flow we need for the application.

I like the combo of both electric and gas the GT3 hybrid is my favorite car.
The 928 is just my toy for now and when I get bored like to make things for it like the cold air system,maybe the edf setup till I can afford a 0-100mph 6.8 second
997TT which may be never lol If it looked more like the 997 GT3 would like the car even more.They need options on the 997TT so it would look more like the
GT3.

inactiveuser1

Know what you mean on the global patent,would have to chase ever company in China etc.Going to try and call Mike today and see what he has to say on the Eram.I did aslo read somewhere on what you are talking of the edf as some are more for air flow to the back than for pressure and need the right setup for the pressure.
