I got an idea, and for once it might work

Post by terkill »

It all started when I saw this 1986? or 85, dodge omni GLH in the local craigslist, so I got bored and started searching videos and found one of a collector GLH-S (the shelby cracked out omni). The guy had a ram-air hooked up in the headlight spot. Where I am it is illegal to have "one" headlight... but I thought of a solution that might work. First I have a question before I go any further that what I've done so far... would it help the tercel in a noticeable way? (Hooking up a cold air intake into the headlight socket)

Since im at my college at the moment, I do not have access to my editing tools or anything remotely useful, so I found the best picture on the forums that I could use as a front end example. (thank you)


My big question is: My state requires "two" headlights. One on each side. Would the two in the middle pass? or would I have to rig up a backlighting (to pass an inspection or to avoid another "defective equipment" warning) on the intake side?

thanks

The air intake already has a ram air intake of sorts, I doubt you would see a noticeable difference at normal driving speeds. The air is taken from the front grill area, which is already a high pressure area. the air "ramming" into the front grill area causes a pressure rise, and the air already is taken from this area. This is how the headlight ram air works, on race cars they need the higher intake capacity than the stock intake system since the engine runs at full throttle all the time.

One simple thing you could change is fix the flap valve on the airfilter housing, that comes from the hot air riser, so it always takes cold air from behind the grill. The colder air is more dense and allows higher compression, improving power and efficiency.

Hey there. I'm kinda curious if you did continue to purse your plans of putting a 'cold air intake into the headlight socket'. As you can see, my friend is having similar idea on one of his project car but he is kinda worried because he know that it is somehow illegal so we're trying to search too if there's an alternative way of doing it. Hoping you could update this post about your previous plan and what happen now with the cold air intake you where trying to hook up.

That trick was used for cars with quad headlights. Remove the inner headlight and run a tube to the carburetor. This was stock on a 63 Ford Fairlane model with the 427. Rare, superbad.

It's easy to do a silly-looking but effective ram air set up on a T4wd. Just cut a round hole in the hood, then feed a PVC pipe the same inner diameter as the carb bore's outer diameter through the hood. Clamp a stocking (thigh high prefferred) over the pipe's opening to keep the bugs out, and voila! Econo Ram Air!

I thought about doing this PVC setup for autocross days only since I have two hoods. Of course I would have a fake wood stripe for added comedic effect. But now that I have a Weber a simple round pipe won't work as the carb bore is of course rectangular. I could do a less silly ram air setup, similar to factory jobs. I remember a friend had a Cavalier Z24 ram air which was simply a square hole in the hood with the intake "foam rubber sealed" onto the hood when it was closed. There are tons of squarish scoops out there, the hard part would be getting the seal right and figuring out how to filter the air. I probably won't do it, but the fake wood stripe is a definite possibility....
It's a scientific fact that in a twin engine aircraft, when one engine fails there is always enough power in the remaining engine to make it all the way to the crash site.

Even better is to go through the local PickNPull and see if you can find any cool looking scoops off of something else you can mount on your hood. If you are going to use it as a daily driver I would prefer to keep it hidden behind the grill. The area ahead of the radiator is a high pressure area anyway (it is where the air stagnates when it strikes the front of the car), so just putting a larger intake duct similar to what is there now would actually provide more ram air pressure than a hood scoop. the area over the hood is a low pressure area. Removing a headlight to use as an air duct will not give you any more ram air pressure than drawing air from anywhere behind the grill.
