Ford 8n with forge blower

Has anyone ever tried to put a hand crank forge blower on a
for n series? Run it off the belt or crank and Pipe it Into the
updraft carb to give the engine boost like a supercharger? I
understand the stock flatheads could handle around 6-7 psi,
but the rpms might be a bit much for the blower to handle
maybe underdrive it to 25% or so with pullies. Would the
updraft carb still work with air being forced through it, just a
thought to pass around.....

I understand it's just a thought, but what would be the point of doing all that to such an old tractor? Just put your money into a better tractor. Those kind of thoughts are for people with more money than brains. Understand I'm not talking about you since you stated it's just a thought.
 
Now deceased Forum denizen often suggested using a smog pump for a automotive V8 as a "blower" for an "N".

I don't recall anyone ever posting about trying one, though.
 
Good morning: If you are just wanting to experiment, I will offer this: In 1954 The Kaiser auto was offered equipped with a McCullough supercharger from the factory. The supercharger was belt driven, and its' output (air) was ducted to a box that surrounded the carburetor. In that way, the carburetor did not have leakage problems, nor problems with float bowl system. It might be possible to supercharge the 8n, but more as a hobby, not a real payoff, in my humble opinion.

I once saw a pickup truck at the rough and tumble tractor
show In Lancaster pa that some farm kids hooked a forge
blower to the intake on the passenger side Door post, not
sure if it was a for but definitely in the the 20-30s, Kinda a rat
rod but intriguing in design, the passenger kid cranked like
hell on that blower, I guess it gave power to the motor or he
wouldn’t of been doing it, I just wanted to see if it was
plausible. Would be pretty cool to see a champion blower
sticking out the side pushin air into the old 8n.

My opinion is that it is an exercise in futility. I fully understand why you would might try it though!

Yup! You never know though when some guy has an itch to try something, what he might come up with. What's that old saying about "Necessity being the mother of invention"?

I guess sometimes just "wondering if it would work" is enough to take the place of necessity.
 
(quoted from post at 22:11:10 06/23/20) 1957 T'bird also had a similar supercharger option.
ome things are simply something to flap gums about. Need more power, buy a more powerful tractor.

I have a hunch you are not related to Tim Taylor. :wink:
 
Who’s also to say you couldn’t put a forge blower on a flathead v8 either? Imagine the possibilities. Forge blowers are fraction the price just have to figure out mounting and compression, could slap an air filter on the inlet hole and pipe it into the carb kinda like a procharger
 
With my 2N & 8N I have always felt that the cooling system just barely keeps up in hot weather as it is.
More power usually means more heat as well.
How are we going to deal with that?

ot to worry, it is all just talk and is never going to happen. Blowing thru a carb & achieving all the necessary correct fuel mixture is very much more difficult than a procharger on a computer controlled/feedback fuel injection system.
 
I can not imagine a hand crank forge blower run at engine speed or any speed could produce enough air to over supply the amount of air the engine sucks in on a regular basis.

If you blocked of the forge blower outlet, I bet you could not get 5 psi on a pressure gauge.
The rest would just spill out of the blower inlet.
The tolerances are just too loose.
 
Very true it’s not a tight fit and heat might be an issue, the
carb does have fuel mixers screws, probably need to richer it
up a bit, but check out some videos on YouTube some kids
put leaf blowers on a truck and it works and puts out power,
the main downfall to any flathead is not being able to breath
probably, a few pounds is all it really needs. Not saying I’m
doing this I’m just asking would it be possible with the stock
set up, or maybe a 8nan would be a better fit lol. But imagine
yourself in the 20-50s trying to come up with a way to push
power out of a flathead i4, can’t really stroke, port or bore
them too much but you have heard of forced induction, what
would you come up with from that time period to do so? A
forge blower from your shop maybe?
 

You cannot not simply blow into a carburator. The easiest and (perhaps best) way would be to install the entire carburator inside a "box"....as has been posted. The blower can then blow into (pressurize) the box and the carburator operates as before, with one exception. The carburator does not compensate for the increased density of the air. You will need to adjust the mixture richer to accomodate the density increase. The throttle linkage and choke control will need to pass through the box. Sealing completely is not critical since the leakage will be air rather than an air fuel mix.

Note, you will have to increase the fuel pressure above that available with the current gravity flow system. The easy way is to install an electric fuel pump to increase the fuel feed pressure as your boost pressure increases. I suppose you could seal the tank vent and run some tubing from the pressure box to the fuel tank. In this case the gravity system should still work. I do not know how well the fuel tank will like the pressure!

...I think my N has plenty of power just as it is.
Back to hoeing the garden.

That's right, After people do all this crazy crap in order to get more power, that tractor still has the same transmission, brakes and rear end.

Just imagine Tim Taylor jumping on that tractor and doing one of his usual stunts.
