Air-Cooling a Water-Cooled Engine

[shady]

would only work with liquid nitrogen. an orifice in each water pump hole, open the valve & go. no fan or compressor needed as the nitro is already under pressure. big heavy tank in the trunk for added traction. Train the trunk monkey to open the valve on the last yellow and it's a win-win-win. It would be spectacular to watch with all that fog.

My 390 was air cooled this weekend. Paid the price.

FElony, are you eating those brownies being sold by a guy at the park with dreadlocks again?

Um, uh, so, you know about that, huh? Damn social media doxxers. Actually, my favorite male vocalist has dreads, too. I'd air that one out but I don't think you guys can handle. FElony entertainment. Mmmm, brownies.

The reason a small water system wouldn't work is wait time at idle over 100 degrees ambient. No real rules there. Mostly meant as a fun thing, so you'll see ATV's and 2-wheeled stuff and what not. No tech inspection.

Since I don't have direct knowledge of this event, that still leaves lots of questions...

Are all these vehicles running in the same class?

My vehicle in question is El Alacran, the '69 Ranchero made infamous in the other forum about three years back or so. It's my Wild Card.

I once helped with the installation of a 427 into a '57 Ford. The owner fired it up before installing the radiator, and probably let it run for a couple of minutes before turning it off. The engine came to no harm during that period.

Many drag cars use only water in the heads---using a fully-filled block.

I daily-drove a 2.3 four-cylinder '79 Mustang with a fairly serious draw-through Turbo set-up, using a DCOE Weber carb. Knew a guy with an early 'vette (265 CID) and I could get him soundly. Ran a 4.62 8" rear. Used a VW aluminum radiator that probably weighed about five pounds. The whole system held about a gallon of coolant. Never had any overheating problems.

A number of those ugly RatRods use a rear mounted radiator and fan. That keeps weight off the nose and more on the rear end.

Yes, so I read. What a drag. Hopefully it'll be a quicky fix, if there is such a thing when you have to pull the engine.

There is a group that runs 1/8 mile dirt drags around Ohio.  They run a race during our truck show in June.  They have classes for everything, 4 wheelers up to semis.  Talk about a crowd!!! It's packed, especially with the 4wd diesel truck class.  Every redneck in the state shows up.

I checked for videos because I couldn't visualize 1/8 mile on dirt. I have seen 300' on actual sand, but 660' on dirt? Yikes! I found several KOI vids; this one appears to be 200' to me. What do you think?

I am thinking I might be able to get 4" wide fence blocks into the Ranchero tailgate.

Ya, they only run 200ft at Ashland.  They basically run on the truck pull track in the center of the horse track.  It's pretty fun to watch, haven't ever actually raced, though buddies have told me to unload the wagon and take it over!!  Ah, not!  I complain about the dust at a dragstrip....doh!   We have a few local guys that run their big trucks.

Now that is the best idea. Easy to do, weight on the back and no fried engine! Methinks this is the best solution and puts to bed any idea of air cooling....which will never, ever work. That or FElony needs to dump that FE and get a Porsche flat-six!

FElony has at least 3 dozen FE's, so that's a lot of dumpin'. Much less strenuous to sit out back eatin' brownies from the Rasta man and comin' up with zany ideas.

However, even without brownie influence, I think I'm going to try the air-cooled thing on an engine stand. I have a couple of disposable motors sitting around, so whatever.

Thanks to all who participated in this thread. Nobody mentioned fresh water marine engines that cycle river water, but that's OK. Next time.

Kinda hard to recyle.....mother earth!

Hmmm, here's a thought.

Three large capacity hair driers with no heaters.  Plumb one pulling air from the top(like the waterneck), others pushing air in say the rear freeze plug on each side?  I'd be curious as to if it would be able to hold enough airflow to control the temperature enough?

An air cooled engine just has fins to carry heat away from the block with air flow.  Since water jacketed blocks have that cavity to deal with you need air flow through it to cool the sleeves.
