Cheap FI Mods ?

Compressed air tanks don't hold enough air, and the ones that do would weigh your car down, plus they lose pressure too quickly.

An air compressor might give some bump but then you'll still have intermitent use.

I was thinking something like this but not Co2 of course just air. It only flows 25 cfm.

Anyone figure out how much CFM would be needed? I was thinking it would be like nitrous shot not long term.

let me just make it crystal clear. anything that looks like this aint compressing air enough to do shit. because i know thats what people are already thinking about. i'm gonna try and find the supercharger that was powered by electric motors. it was a roots type. post it up if anyone else finds a pic.


ok, check this shit out. these are actual compressors, not just a high velocity fan.

900 - 1,200 cfm perhaps... I'm not sure.


I know 25 is not enough.

I had links to Thomas Knight and the E-RAM as examples... all of them are where they should be... in the turbo FAQ thread, if you guys ever care to look through it.

Why not use a tank of compressed O2 injected into the manifold like a NOS set up...O2 is a good oxidizer, no? Pure oxygen would give your engine a kick in the ass with the right fuel management...plus compressed oxygen is easier to buy than NOS and you can even get a machine that will create and compress pure O2 from the atmosphere.

I think pure oxygen would be explosive or melt your engine, something like that.

Right, so after all this, the simple answer appears to be: any electric blower that would generate enough air pressure would require too much current to be viable - ie. the one site mentioned a draw of upward of 700 amps(!!!!).

See now, that's all I was overlooking... that wasn't so hard, was it?

yep and another search here I stated on the tomas knight thread.

"if you uped the voltage what happens to the current draw?"

I think I asked our resident no it all ASE SAE engineer. The standards for cars goes to 36 volts in a few years. So not to far future it could be viable.

And CFM is a measure of volume not pressure. There is a differance.

Well that's simple: it drops proportionately. Basic electrical theory.

Interesting... that's gonna wreak havok with aftermarket electronics designed for 12V. Back in the day when I was working installing car stereos, we put systems in a couple diesel-powered Toyota Land Cruisers, which use 24V systems... the regulator modules we used were fine to run a deck or alarm, but just couldn't handle the current required by anything more than about a 20W amp...

Obviously, but the result is the same: not enough air movement.

nothing REALLY works except turbos and superchargers, all that E supercharger and all that stuff just doesnt work and the stuff that does "work" just isnt really practical

Well said.

I think my understanding is they will have batteries with a 12v post (tap) as well .

you want cheap power?? nitrous is the only way! im tellin you. why put an air tank in your car when all you got is air? put the same tank with nitrous in it and you will be much better off.



oh and btw dont call me when you blow your car up

[speedpenguin]

i concur. the money you spend fabricating this thing. is better spent on nitrous. it's safer, and already proven.
