I just need to find something powerful enough to boost in a sealed intake tract. I KNOW that a 3000cfm electric fan through a 3.5" hole is going to create quicker air going through the airbox....you can't argue that. Will it pressurize? Don't know but it couldn't hurt to try. I could set up a test with just the custom box, air lid, Maf, & TB and see what comes out the other end. Need that flow bench & velocity probe charlie! I'm working on making one of those too. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> Quicker throttle response & revs probably if not a little boost??

Fans only blow air, but with a restricted outlet the air either leaks out or gets pushed through given enough power. Don't forget about the almighty power of a shop vac! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> And I KNOW it builds pressure or you wouldn't be able to flow cylinder heads or suck up anything.

I can see it now....Jantzer Performance Vacuum Cleaner Supercharger powered by Craftsman wet/dry vac. LOL! Filter built in the Vac, it's the airbox holding dry ice and it'll fit fine without that front bumper support in. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Now is that not a crazy idea!!??

 

LOL that would be wild hahaha <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Also retrofitted with a honda gas generator in the trunk to power it!
LOL!

I realize that but what if there is too much load on the alternator though <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Save yourself some trouble, and look for a pump. My brother pointed out some fan "supercharger" for imports to me before, and all the reviews said it wouldnt do ****. Ill grant you that a fan would be superior to a "n/a" ram air, but if you are serious about making a little bit more than normal power, you'll look for a pump. Theres bound to be something out there that would work. I wonder if you can gear drive a turbo? Maybe a electric motor spinning a small turbo off to the side that you can plumb straight into the maf?
Just throwing some ideas out to you - i always love brainstorming crazy **** like this.

 

Not an expert or anything but with a fan once you read critcal speed and the fan produces the flow at such and such MPH, once you pass that it becomes almost like a block blate and restriction. You would need a fan that not only produces pressure but can maintain well over 150MPH thrust in order for it to work and have any kind of effect. I would think. Other wise you are just putting more restriction in your air flow to the motor. Now that Ram Air scope might be interesting. You may want to secure the back side of the air lid though, the pressure could blow that off. That would be interesting as well. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" /> But if you were to do that just find an old junked rig with a turbo (big diesel turbo <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> ) and just build a kit for it. Of vourse that could be interesting. Probably slpit the block......

Since we are on this subject, after a recent dyno session we came to this conclusion.

Idea 1: If you where to get a wet dry vac, moount it where the air enter sat the bumper (some mods of course for fit) rig a inverter for 110 and run the hose up to the MAF. Of course taht would be hard to adjust do idea 2 comes into play

Idea 2: Get a leaf blower mount it in the same place. You'll like this. Run the throttle cable of a lawn mower to the dash <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> for adjustment and one of two things to start it. Have it pull started before you start the car, and or rig a 12V starter to it. Of course we actually thought of puting a leaf blower right up to the MAF when dynoing to see if we got any results, just for ***** and grins. No one had the ***** to try it though. But it was a thought......At this point though you now qualify for a japanese sticker that translates to Honda Powered. <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" />

Since you've been thinking, how about thinking about this. You know that clutch/pressureplate/flywheel or flywheel and torque converter do a lot of spinning at high rpm, right? And its bound to make pressure inside the bellhousing too, right? What if you made a gasket for the bellhousing, and put a hole in one side for air to come in and another hole in the other side for air to go out of it? Now the flywheel has become an impellor in your new ghetto supercharger. Then what if you filled the inside of the bellhousing with that foam stuff that you shoot into a hole then it expands and hardens. Then you'd have to pull it apart and cut a path for rotating parts, and clutch forks or whatever. Think that would make some positive manifold pressure if you routed a line from the "exit" hole back around to the intake tract?

Stop it...your making my head hurt. The ram air idea is cool, and at higher speeds it obviously will help. But, a poormans supercharger?!?!?!?!? Any pressure a fan would devolope (small amount) would only flow backward out of the intake. It is not a sealed air pump. Put a piece of cardboard in front of a fan in your house. cut a hole in it and put it up to the fan. The air coming through is only slightly accelerated, the rest of the air is pushed out the back of the fan or sides. NOW stop it, you making my head hurt!

The fan or whatever WILL increase air velocity throught the LID/MAF. I did say SEALED BOX that also has inlets on both sides for your FRA piping like T.Burgers. It would be positioned to atleast be directly pointed up the intake tract thus less obstructed flow and few turns. Air SHOULD take the path of least resistance.

This isn't a mod for a guy that runs fast on NOS. It's for a guy that runs fast NA but wants to be faster under NA rules. And for the guy that is so intrigued by doing what people say can't be done. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> Look at the replies, obviously it's entertaining and fun to throw around ideas.

The cardboard example is ludicrous. We're talking in a funneled setup not a pin hole in the middle of a cardboard box. It's all about the Radius, whether it be the MAF/TB/or the poor man's supercharger. Somebody knows something. Now it's the VELOCITY STACK POOR MAN'S SUPERCHARGER!

On a more serious note, I'm seriously thinking about trying a dual TB setup with a custom manifold. Either NA or try to mount a roots blower up to it. I just know a guy that can do all the fab work on the manifold. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> But that won't happen for a little while, I've still got easy mods to gain power yet.

Logged my manifold pressure today using a aeroforcetech obd11 gauge. Idling it is -6.0psi but at high speed 100mph it was a steady 0.3psi.
I have read that naturally the car should be at around -1.0 to -2.0psi or even -3.0psi. So it seems an over radiator intake with a straight intake tube (no filter) is giving a gain of at least 1 to 3psi.

Is this data interpretation correct??

 

what in the hell did you bring this back for?

 

h ah ah ah ah aha LOL
