need a belt drive blower

[missourihick]

I have an old ford farm truck with the 6.9L diesel engine. It has always been smoky when it is pulling,which is normal for a non turbo diesel.I turned up the injector pump and made it even smokier. I got it in my head to biuld a sort of homebrew supercharger. I am looking for a belt drive squirrel cage blower with an outlet of about 4 inches. Can anyone think of where to get a blower to tinker with. It would need to have bearings instead of bushings like a furnace blower. Who knows ,if this works,I might try it out on the old diesel farmall.

You have me curious-keep us informed.
Maybe try an impeller from a vacuum cleaner?
Maybe try running that motor from an inverter to test it out?
or
A long enough extention cord to run from the pumphouse to the pasture-LOL

Turbos arent that expensive. Maybe you can even find a complete set with manifolds and exhaust elbows on a wreckyard ?

I dont think your living room refreshment fan is going to create any substantial boost, and if you rev it so hard that it WILL boost, the blades will spin off the fan and find its way through, into the engine... :-/

I have an old 1.9 Volvo turbo diesel in the workshop, we want to build a dirt buggy around it. My current car is also on its way out, because it is old and last week my boss hung his 12 ton trailer in my front bumper when he turned off the premises onto the road...

So within 2 months i have another turbo, which i think will fit one of our tractors pretty nice... i think 1.9 liter at 4000 rpm would be pretty close to the air flow of either the 2.7 or 3.5 of our tractors...
The Garrett turbos i bolt off my old cars, are probably not big enough for the air flow of your 6.9 truck engine, but if you take a look at construction equipment wreckyards you may find one. Something that comes off a Cummins 5.9 for example.

My cousin in Canada had a Case 730 with a turbo that he bolted off a seized industrial Cummins, from the company he worked.
It whistled all the way, right from the moment you started the engine. He said normally these engines allways smoked a bit, but with the turbo the exhaust gas was invisible clean, and that tractor would go like a firetruck.

I have to agree that it just isn't going to work out. Just look at all of the electric blowers that guys are selling on ebay to the kids with the Honda's with garbage can mufflers. I'm sure it's a money maker, but not a power maker!

I would agree that you should search for a turbo setup for what you have that you know will work.

Most belt driven blowers are made to produce CFM with no real restrictions and not designed to produce pressure like a turbo is.

Now if you could find a REAL blower from an old truck, that could be a different story. A lot of old Detroits had them.

I have to disagree with you about the diesel smoking. I have had two Ford diesel's , one w/ turbo and one with out. The one without did not smoke when towing. You might need to rebuild your injectors which is usually the couse of a smoking diesel. A turboed engine merely allows for the top HP to be devolped faster and also has a few other good points.

How good is your engine on compression ??
My Volvo uses a droplet of oil, but when accelerating fast in a low gear it puts out a nice cloud of black smoke. In higher gears the engine doesnt rev up so quickly so the turbo has more time to keep up feeding air boost to the engine. smoke is either due to excess fuel injection, or loss of compression.
