Fuel Injection for Ford 8N?

[dullpain]

Go for it - you'll have the coolest , most unique 8N on the planet.

There are plenty of people who have converted the old Toyota Land Cruiser 'F' and '2F' engines to run fuel injected. They do it for easy starting and marginal fuel economy increases, but mostly they do it to better enable the engine to keep running when operated at extreme angles during rock crawling. The carburators can be tuned to do pretty well but will ultimately starve the float bowl at angle.

Most commonly used is the GM TBI system. It requires a junkyard raid for both the six cylinder HEI ignition and the fuel injection harnessing, fuelpump, and sensors. The two injectors are contained in the two barrel throttle body and an adapter needs to be made up to run the throttle body on either the one or more common two barrel manifold. (I'm not aware of a one barrel TBI, and would love to be informed of one if it exists).

Lot's of successful systems have been made up using the GM controller but the best for tunaility seem to always be the Megasquirt adaptations, That system can be made to fuel most any engine and all parameters are easily adjusted using a laptop and (I think) included software. The site posted tells all about it.

If you can solder electronics and have a cooperative (read low priced) part source I have read of the job being done for little over $200.

The megasquirt boxes were being sold in ebay for as little as $130. or so when I was last interested. Don't know the current situation or price.

All that said, I think if it were mine I'd be wanting to adapt one of the small diesels that are widely available. A huge heavy flywheel powered up by a small diesel could move a mountain!

My 9N purrs right along and I enjoy the simplicity of it and it's ol' school feel. I use my Mahindra for milage and getting the real work done. Ths 9N still does the bush hoggin' and box blade work though.

I could understand if you were replacing a Quadra jet on a hopped up 350. But, an 8n carburetor has minimal adjustments (and for that matter compression, cooling capability, etc) and it always works. On the last 8n we bought it took less time to adjust the carburetor than it took to load the fuel injection tuning software on my lap top for BDS's DFI, not to mention doing the actual tuning. I've been told, If an engineer designed the anvil it would have 47 moving parts and never work. To put it in other words your tractor is still running after 50+ years, you replace the cast iron carburetor with a bunch of electronics it certainly won't be running in 50 more. Finish the 944 and show us some pics of that project.

The old Suzuki Sidekick/Asuna Sunrunner/Geo Tracker/Chevy Tracker (All the same vehicle with different grilles and rims) used a single barrel, single injector setup.

n cooling systems are way oversized for that anemic hard breathing 119ci flathead.

My opinion is that you will not see much increase in fuel efficiency with the fuel injection setup. Henry Ford stuck with those flatheads , but in some tests they returned better fuel economy than the more modern OHV engines competitors used. Fuel injection alone provides very little improvement . Fuel injection, combined with digital mapping of injection timing, injection volume, spark advance, increased compression ratio, and more efficient exhaust manifolds would result in better efficiency and more power, right up to the point where the rods and crankshaft disintegrate. If you're not looking for more power, then I doubt you'll ever recover your investment in fuel savings. And, those old tractors already start in any weather almost instantly with their ancient carburetors, and no exhaust emission controls. Probably the best aftermarket piece of equipment offered was the dual range transmission adapter, which gave the Fords the low speed creeper gears that Henry Ford cheaped out on. There were conversion kits available to install Ford flathead V-8 engines, along with bigger or dual rear tires. Now, if you just want to hot rod your tractor and/or experiment with fuel injection, then that's another story. Go have some fun .
But keep the original parts around so some future owner can convert the tractor back to stock condition.

I am thinking of converting my new to me 1947 Ford 8N to fuel injection and Electronic Discharge Ignition System and do away with the old carb and points and condensors. It would maintain the govenor to regulate engine speed. The fuel injection would give it more reliable starts and allow the motor to run at a higher efficiency.

Has anybody done this?

I don't want to rain on your parade, but what do you expect to gain on 6:1 compression ratio L head engine running at 2000 rpm? If you are doing it for the challenge, have a go.

But don't be expect big power or torque gains or large BSFC reduction. You can put an electronic ignition in if for ~$100 and a big coil (that won't buy you much) to improve starting and rid yourself of points and condensor. If you want reliable starts and good running, give the Old Marvel-Schebler TSX a good cleaning and a rebuild (~$60 for a gallon of carb cleaner and a rebuild kit+ your time) add the electronic ignition and you'll have reliable starting and near spec performance if your engine is in resonable mechanical shape.

Good luck, whatever you decide to do.

before I'd go to tbi or anything like that.. I'd turbo ro supercharge it.. flatheads biggest issue is breathing...

you can get miserly carbs.. but the breathing being nat aspiration is the issue, when looking at efficiency..

ps.. if you want to go to fi.. look at megasquirt...

So why was this zombie brought out ?
