Started fabbing up a poor mans ram air

No pics just yet. Tomorrow. I have about $70.00.00 in it.

$5.00 for air filter.
$3.00 for new wing nut
$3.00 new carb stud
$5.00 for dryer duct
$5.00 for inlets(hardware store stuff )
$10.00 for a 1984 mustang dual snorkel air cleaner used from swap meet earlier this year
$25.00 for 4 inch hole saw and adapter bit.
$10.00 for paint.

I just want to see if it works. If it does I will spring for a set up from
this company
http://ramairbox.com/install.html

I also decided that the grabber grill gets in the way(lights) So I painted my old original grill black and I have one of those billet aluminum maverick emblems made by 69ina1/2 that he was nice enough to let me borrow a blemish one. If I like it I will buy a perfect one from him.

If it works I would sell this one on the board if somebody wants it.
Hoping the weather holds out for this sunday for the MCG drag event at National trail raceway to test it out.:evilsmile I may beat "Pinky" yet

 

I would be very interested in seeing the set-up.

 

I would like to see some pictures of the finished product. I have an extra dual snorkle air cleaner lying around that I was thinking of doing the same thing to. I would like to know how it works.

Thanks
Don

 

Just for info, I made one a few years back for my 331. Utilized a stainless paper towel holder box found at a Goodwill store. Fit on top of 750 Holley with a 3in pvc tube inserted into each side. Ran heavy duty hose to another pvc tube mounted in one of the four headlight assy. that had been removed for racing.(78 Fairmont) Only gained 1 mph and no difference in et. Probably will depend on engine setup on how well it works for each application.

 

That is discouraging. It looks bitchin nontheless.

 

I've always wanted to make a functional Grabber ram air hood. That would be great!

 

Ivey Collins had one of those "ramairbox.com" set ups on his car and he posted on this board that it was worth 2 to 3 tenths at the track.

He said he proved it by removing it and the car slowed back down.

 

If I am remembering my understadning of ram air. It has to be in the frontal area of the car to pick up any air. airflow is minimal near the middle of the hood, ( hence hi rise hood scoops) So the ports in a grabber hood would see little if any air flow. Now, a setup wear a hose came out from the Grabber port through the underside of the hood and up to the grill area might work, in other words run the ram air runners under the hood then up through the scoops back down to the intake, but then why go out the hood only to go back under, unless it looks real cool.

 

PS the other aspect is you want the air Cold, in the middle of the hood it would be warmer than at the grill.

 

Saw a car at a show recently with a homemade ram air. He had a plastic mail box, like they deliver newspapers to, bolted to the carb. stuck up above the hood about 10". Bet he didn't have no $70 invested.

 

You want to be careful with "ram air boxes" too because if the pressure is too high it will lean the carb out because it will raise the pressure in the air horn and venturies - just where you don't want high pressure. The low pressure is what pulls the fuel into the manifold.

 

Just guessing he was running too rich in the first place and the extra air leaned it out which made it run faster. In my case, I had tweaked with the jetting for optimum fuel/air mixture on my engine and weather etc. That is why the lean condition only made a small difference.

 

Huh? Don't tell that to the guys with the blow-through supercharger setups. The more air that passes through a venturi the more fuel it pulls from the booster, up to the limit of what the main jets can supply.

 

I will post pics later tonight. I tested it:evilsmile with the butt o meter. I think it works

The true test will be this sunday at the track!!

 

Fwiw: The only thing these induction systems are good for is cooler air temps, therefore more dense air.

The term "ram air" is misleading... as our cars cannot attain the speeds needed to 'force' air into an engine. Sorry, no supercharger effect here, just cooler air... most of the power is made by leaning out the fuel mixture. However there is something to be said for the cooling of the combustion chamber which allows more timing, leaner mixture, or lower octane requirements... chose your poison.
