I just had a little moment where I thought I'd stumbled on something that hasn't been done, but I'm sure it has to some effect...

I was thinking about doing my own CAI and I was wondering how I could get high pressure cold air into the engine without spending thousands on a supercharger... Now heaps of you will go "dream on buddy" or "thats a recipe for disaster" but here goes:

What if, in ordinary 90mm CAI piping, you had a turbine or fan driving air into the box through the filter and through the TB into the engine? I'm sure some kind of addaption could be designed to do this without comprimising airflow, temp, safety and budget. And, if it can be done, how efefctive would it be?

The kind of motor I am thinking of is that out of a vacuum, hair-drier, plumbing/ducting applications and should need to be a powerful air mover and run off 12v. It would also need to be mounted within the CAI pipe or adjacent to run a fan/turbine within the pipe.

What do you recon? Please let me know what you think.
Cheers,
Danno

Look at this http://www.aussiemagna.com/forums/showthread.php?t=23679&highlight=electric+supercharger

It can be done but to whether its worth it or not is another question. And you will need a very powerful motor and efficient ducted fan to make it worthwhile.

hehe that thread was up the other day... should have read it propperly!
I guess that means you can get kits then...

I would like to know more from people who have aco post their Opinions on the performance difference.. I do not trust the Advertising on that their site... 1 PSi of Boost from a PC fan is a little hard to believe..
Not to mention it would cause the car to run rich..

you'd need a very efficient fan to do that. anything less than that would just act as an obstruction.

the car's induction has been tested by engineers at mitsubishi....i'm not so sure your garden variety aussiemagna enthusiast could improve it too much :P

anyways, u could try make your own motor or something, but one thing is, if u have the motor inside the piping, it sorta defeats the purpose.

How else could you do it though? the motor would have to fully crank to be efficient hey.

I'm thinking leaf blower, separate engine to force induction... :D

Here's another idea... reroute (some or all of) the AC ducting to the filter box... hmmm...
I wonder if you'd get significant gains or if the motor running the AC would just crap itself?

Umm... i wouldn't say its worth the effort...

Anywayz... my TS 2.6l sounds like a vacuum cleaner already. lol

do you think there's a way to run a belt off the existing fan/crank/whatever to run a fan/turbine to help increase induction pressure?

Is there a major reason noone has done this? or is this just a backyard s/c?

from rpw:

Certain models of the Mitsubishi range run the Mitsubishi MAS / MAF sensor which is an the electrical metering unit that goes after the air box. This unit reads how much air passes through the unit via ultrasonic waves and is a oval shaped unit. One of the major problems we see is the fitment of universal K&N Pod Filters which then start creating problems with idle or power by running rich, stalling etc.

The reasoning behind this is the honeycombed section requires the air to be very straight and clean in order to rear correctly. A pod filter is cone shaped and instead, causes a swirling action which confuses the pod filter. Additionally many of the adapters fitted to the MAF / MAS sensor is square and cuts off some of honeycombed section in order to bolt on the round pod filter.

would a fan not cause swirling of the air..................just a thought

There is an electric supercharger out now in the states(USA) you can get them on ebay if you are lucky for about $185USD not sure how good they are or if they really work and it depends how much more hp you want

if u think of using a leaf blower engine update the filters on the engine cos they suck and blow to muhc dust/crap.....
