I was searching on Ebay for TRD superchargers for the 1zzfe and going that route for FI. I then came a cross ducted fan design for an electric supercharger. I realize that the one for sale was a total piece of crap and not worth the plastic it was make of but it got me thinking. I think that it would be possible to make a I.F. design using a ducted fan from a remote control air plane. I think this would be the best possible marriage of technology and our cars you could make a completely custom boost profile. Full or partial boost at any RPM not dependent on engine speed or load. I am thinking of make prototype of one for my car but I don't know a lot of information. I think I would use a PFC to control the fuel and timing and for the time being make a liner boost profile using some sort of co-processor or something. I still have to find out how much flow I need to create enough boost I am thinking 5 PSI for now. I think it would be a safe amount of boost and then could be scaled up. Unfortunately, the ducted fans used in remote control air planes are measured in pounds or kilograms of thrust. I wonder if there is someway to convert pounds of thrust to CFM or liters per minute. I am looking for thoughts and ideas all are welcome. My intent is not to hurt the car or decrease it's reliability or damage it in anyway.

Thanks
Chris

Obligatory


If you have to ask questions of this nature you do not have the engineering or mechanical aptitude to DIY; therefore you will pay someone else to do it for you. At that point you'll realize that for the time and money you spent you were better off using a conventional f/i setup.

I build and fly RC planes. I did have a large EDF jet a few years ago. They will move a lot of air but I have no idea how good they are compressing air or how good the duty cycle would be for constant running. I find it an interesting thought just like electric assist power steering reducing the load on the engine. Do some research and good luck.

Well, I think that was a bit much. :)

Your average supercharger is a compressor requiring a bunch of HP to run. Now think about how big, say, a 10 HP electric motor would have to be. Yeah, not gonna happen.

I was flying EDF jets last year and it was like a dose of pure adrenalin trying not to crash it.
I realized that it was beyond my skill level not so much that I thought I couldn't fly it but my wallet said otherwise.

When I spun up that motor I was amazed at how much was being ejected from such a small opening.

I have one and I run 600hp they are awesome
Is that all?? you must have the slow one?? you running the full 12volts??

Electric ? Na, that won't work. Not enough power.

I strapped two Stihl petrol-leafblowers to the car, haven't dynod it yet, but I estimate around 750 hp !

And its reliable, I just have to check the ducttape every time I take it out !

You would need an overly powerful electric engine to force enough air in... the solution paid engineers found for "supercharging" a cars performance with electric power is called a hybrid.

In the end a hybrid serves a similar purpose to a supercharger in that it provides more torque and makes the engine feel a bit more like a larger displacement engine. It has also been put to use as a NOS replacement on some of the CRZ race cars. The hybrid system is disabled by default and the drivers have a push to pass type button setup to give them an extra boost of hybrid power when they need it.

With improvements in hybrid technology i could really see it becoming an equal to forced induction without loosing any of the benefits of an N/A engine.

I get that adrenalin rush every time I fly something with a year or two of time in it plus the $$$. EDF's do move a lot of air but I prefer props on round motors personally. Electric forced induction could work am I sure. I don't have any idea of reliability or cost to do so, nor do I have much interest as I like NA on the 1zz at that. Just a low rev'n slow poke enjoying the ride.

Here's something much more intelligent to think about.
Electric boost at low rpm to reduce turbo-lag.
It will take about 1,327 times the skills and intelligence of the OP to make this happen.

believe it or not an SA performance mag did a test like this for fun, modified a petrol leaf blower and did some runs
