Forced air induction (RAM air)
I like the looks of these. I'm probably going to build my own. I'll also be putting an ozone generator between the intake and the snorkels somewhere.

Forced air induction (RAM air)
The ram air is a good idea. I remember seeing a setup on a N/A 2.2 or 2.5 Chrysler. The guy put in 4 to the front of his car. His HP and mileage went up. Can not seem to find the URL for it though.

Thanks for the links.
Easy to do you own though, couple of junkyard snorkels/hoses.

How much air does the typical engine consume?
Could you adapt the ram air to high-CFM electric blower to blow into the snorkels? I'm thinking the type of fan that's in your heater/AC but bigger and with higher CFM rating... I guess this would basically be an electric turbocharger. The problem would be it's a constant, so you'd be getting the same amount of air at idle as you would at full engine load.
Unless you could build your own "super charger" using a squirel cage fan...

As I recall its displacement X RPM / 3456 will get you in the ballpark.
As for an electric supercharger...several out there have tried/are trying.

Way back on the old Yahoo MPG list a guy talks about making a shroud to force warm air from the engine fan into the carb on an old truck...got a major increase in mileage.

Why warm air? I always thought you wanted to get as much cool air into the engine as possible. Isn't that why these snorkels are put on in the first place?

It depends on one's goals. Cold air helps with more power and can prevent detonation. Hot air helps with the vaporization of gas.

By putting a ram-type funnel behind the radiator, you get both hot air and the ram effect will at least partially restore the lost volumeteric efficiency of the hotter air.

Ok, so you take a heater "box" (containing the fan & heater core) and duct it to your air cleaner. Run your fan on, say, 36v and have an ozone generator somewhere in the mix... Then you've got hot air that's somewhat pressurized riddled with ozone. Has anyone done this?? Would this work?

There has been a lot written on electric superchargers. Most give 1.5 to 2.5 psi boost and draw 50 amps and only come on at WOT.
I have put ram air on several of my cars and it works. My 4 door Escort would do 90 mph in third gear and still be pulling strong (strong for a Escort that is).
The heater squirrel cage is said to work but I have never tried it. Running it on 36v would keep the amps down but would work your alternator hard.
Fuel for the hot air vs cold air debate. I think for low dollar modifications for mileage you want either hot air and cold fuel or cold air with warm fuel. I don't think you get as much turbulence in the combustion chamber when both are hot or both are cold. I base this theory purely on my understanding of fluid dynamics.

There used to be cylindrical electric fans sold on Ebay that went in the inlet and were supposed to slightly boost the intake pressure.
I think you should concentrate on hot fuel and keep the air somewhere in the 110F range...because fuel holds more heat and is what is being vaporized...cooler air is more dense and so contains more O2.

E=mc2 That sounds like it should work good. bemet

Seems to me those fans are actually used in boats/yachts? People we at one time repurposing them as 'electric superchargers' and repricing them...WAY UP. More advanced electric superchargers now adays use as many as three starter motors to get them up to speed. For short term use only!
re:Forced air induction (RAM air)
Cool Idea mate. This is actually pretty interesting. I hot the same idea before on the intake but I didn't do it. Maybe you should post a result here. I already got parts for this. I got a short ram intake right now. A good way to start I think.
