Ram Air Induction

[Rollinflatty]

Hey guys, I was wondering if anyone has made or has seen a ram air induction on a 50 plymouth coupe. I have already cut out and fabbed one incorporated into the doghouse, going with the angle of the grill. I mocked it up using 4" stove pipe but only had one carter b&b carb on at the time. She ran better top end but needed more gas, so now I have twin carter b&b's on. She's a 218 bored out .40 over with a mini hei from Tom Langston. I also put in a 5 speed from a 89 C10. She runs 80 down the highway at 3200 rpm but I would like to see how much I can push her. I've heard storys of them running in the 14.5 in the quarter back in the day but I really don't know how? Any info on this?

I haven't done a ram air system but I have been playing around with putting a cold air induction system on mine.

Here is what I am looking at.

 

 

 

Lets see a picture of what your setups look like.

Not for a 50 Plymouth, but this was my go at ram induction/fresh air.  6 inch collector in the headlights to a 4 inch dryer hose, to the air filter housing.  70 Buick, I wanted cold air and didn't want to cut the hood.  This picture was taken the day it received some decoration.  Oh, the college years...  I drove it like that for a couple more years.  This was the car I had for 17 years and 200,000 miles.  I still miss it.

Any piping of cool air from in front of the grille, or wheel well, etc, will give you better performance.  i did this years ago at the drags in my slant six 72 Demon.  I ran with everything in stock for...think I was about 17.4 sec.  Then I switched to dry duct hose from the grille, through the rad support, to the air cleaner....think this dropped me to about 16.9sec.  I then removed the paper air cleaner...netted another couple tenths.

Here's a couple pics. I don't have it hooked up now but I used a flat k&n filter at the cowl then had the pipe after that. I would like to continue the flow of the air with minimum angles to get as much air as I can. Right now when I run it without it hooked up there is so much air coming in that it lifts the hood where it meets the firewall! I'm going for a "vintage" look but haven't been able to find anything period correct.

Al this is kinda what I had in mind. Pretty cool. Looks like you used polished galvanized exhaust pipe. I want to do the same thing but don't know wether to have both pipes directly after the filter or use a large pipe and funnel down to a smaller one as it gets closer to the carbs, that way it speeds up and forces more air into them.

[thrashingcows]

If I had dual carbs, then I would have a larger main pipe, then do a Y well before the forward carb and then have them run up and into the air cleaner hats.  Like you said you want to minimize the number of sharp bends.

I am looking at using 3 inch aluminum pipe like the link below. It comes in alto of variety. I have the duct type hose as well but was worried about the turbulence from the ribs. That is what is in the pic above as well. I picked three inch as it should provide more than enough air as the carb bonnet had exactly that size and fed a larger engine with smaller carb bores. I drilled it out to fit the bb's bore and spacing.

It comes in allot of configurations.

I was thiniking on the same line as you Tcows. Thanks for all the info guys. I'll post some pics when complete.

I seen this cold air intake system on ebay for $375.00.....

I think I could go to Lowe's Home Improvement and get most of the parts

for alot less money.....

[Alshere59]

Wow $375 is more than I have in my carbs, intake and cold air intake. I guess you pay to have someone figure it out for you.

[Don Coatney]

I am curious on what the expected improvement will be for such an installation? Major gain in horsepower or a gain in bragging rights?

[Alshere59]

I was looking at a possible gas mileage improvement. That and I have seen a number of threads that show the small chrome air cleaners as restrictive making it run rich. Looking at something besides just stacking the filters.

[Rollinflatty]

$375 is crazy! I would rather fab one myself and get what i want.

Don, I would like to gain more top end h.p...as everyone knows these flatheads have plenty of torque but are short on h.p. This may be the best of both worlds, torque off the line and a gain in h.p as the speed increases. I don't think i will get better gas milage, with the dual b& b's i think i would get worse gas milage because an increase in air means there needs to be an increase in gas. I know when i ran mine with a single b&b and hooked up the air intake i got a noticeable increase in h.p. after 40mph. I hope the same happens now but with more top end h.p.

and I am sure every 60 or 70 miles you will have to pull over and siphon out the extra gas in your tank..

60 to 70 miles? I haven't pulled over that often since my wife was 8 months pregnant.

For only $299, we can buy,(ebay), an electric supercharger/turbo, turbonator,

cold air intake system. Can produce up to 20 more HP(hampster power).....

Seems like only a year ago, they cost $10.......

I dont think this would work on an open to the atmosphere B&B unless you boxed the entire carburetor.

[greg g]

Like this perhaps?

 

[Alshere59]

That is to wild. Tell you what if someones buys it I will try it. Oh I would need two I guess. Other than that I leave it to a more adventerous soul. Not the pringles can either.
