Fuel Injection for Ford 8N?

[speedracing944]

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?

Not that I've heard, but it sounds pretty cool.

Are you planning on adapting a 4cyl car FI and computer to the 8n or go with an aftermarket kit ?

I would use the standalone system by megasquirt. This is a standalone which gives you complete control of every engine parameter including air/fuel ratios and ignition timing. I would use the Ford (car) 4 cylinder EDIS ignition system which runs off of a 36-1 crank mounted trigger wheel.

What is great about the megasquirt is you can adapt it to anything from a single cylinder lawnmower engine to a 12 cylinder F1 motor turning at 16,000 rpm.

This is the same system I have built to run the Corvette LT1 motor in my 944S

It appears to be an easy modification to design and put together.

Gotta link for megasquirt?

Wow.. what a waste of money on a poor breathing engine like that.

For less money and work you could simply get a NAA and be probably near the same power

There are 2 common 'drop-in' electronic ignition kits.. a hobby kit that still uses breakers as a trigger, and a tru breakerless kit which comes in a few styles, even one allowing you to use a hot non oem round coil and wider plug gaps..

Do that.. get domed mercury pistons, snath the liners out and run bare in the block.. mill the head to min clearance, have a hot rot shop work over the cam, relieve the head for clearance .. get new rotaing valves, have the block bored for cam bearing inserts.. rework the governor.. and make a supercharger for it from a smogpump ( yes.. there are plans on the nternet for this ) and you can spend thousands of dolars to get an engine that is jst a few mre hp than stock?

As we say on the N board... 'How fast is your wallet?' If yuo want to trik it 'just because'.. and you got loads of cash buring a hole in yor pocket.. go for it... if you just need more tractor.. buy a 860 and if yuo close one eye.. it will look about the same as the N.. and have 2x the hp... and cost probably 200 - 1000$ more than the N.. and be a way better machine..

Your souped up N still has no live hyds.. though yo can adda an engine mounted pump /live hyds kit... probably 400$... no live pto.. though if you search you can find a very rear dearborn live pto kit.. probably 1000$.. might as well get power steering.. add 1200$

in the end you will have a machine that the weak link is now the divetrain.. and it will probably cost yo about 10 thousand dollars.. and .. not be as good as a 3500$ ford 860 with a common dealer option on it..

Do take pics. i wouldn't mind seeing the work.. especially if it wasn't my money! (wink)

There are plenty of re-powered N's.. one with a turbine engine... neat things to look at.. though no practical use..

Soundguy,
I understand the point you made of modifying till your wallet is empty. If this was the case I would run a Garret ball bearing turbo at about 1 bar and a standalone but hot rodding is not what I was looking for. I was more targeting increasing reliability and motor effieciency. For this those who use thier tractors often fuel economy is important. I don't use mine for much more than cutting the yard and pastures and for snow removal.

Cost for parts for a project like this would be about $600 which would include the standalone computer, ignition components, and fuel pump and pressure regulator. It would interface with a lap top computer and could be programmed on the fly if you so wish.

Best regards,
Speedy

600 bucks sounds cheap to me, must have changed a lot since I looked at converting a 91 crown vic over form the dang cheap old variable venturi carb to fuelie setup, (was going junkyard injection of a mustang onto the 351 police inceptor engine, I sold the car for demo which the guy did day he picked it up as he backed it off trailer and right into the neighbors honda! left red paint on the side/rear bumper of the Crown Vic and tore the honda hole back end nearly off left bumper, tail lights and back spash pan setting on ground hanging by the other side tail light wires!


I snatched off the licence plate & fled the seine hahaha

If your sole purpose of the tinkering is effiency.. then leaver everything stock, and add that smogpump-super charger. Biggest stumblink block that little flatty has is breathing. the carb is next in line.. the ignition is bottom of the bucket.. except ththat if you went FI.. then you would want programmable ignition.. ( I agree on that point ).

Have you thought about a TBI system retrofit from a junkyard?

Never thought about retofitting TBI system. Is there a system you know of which would be easily compatable? I think any car systems out there would be way oversized for the little 27 HP that the 8N puts out.

I think that could be fixed with in the injector computer.. if you could find someone wif a eprom reader to get int here and program some new tables for ya... Kinda like a 'superchips' setup.. only for an 8n.. (wink)

I think one of those single nozzle setups like I say on late 80's 4 bangers would be a starting point anyway.. Would still be quite a project though..

Hmm.. anoker thought would be a mechanical injection pump.. maybee something like the 144ci diesel that ford had for the hundred series.. and then go EI.. on top of that.. etc.

Course.. this would probably only be adaptable to a side mount distrib setup.. etc.. hmm...
