So.... the Ford/New Holland/Shibaura 1720 features a 1.5L OVH mechanical injected 3cyl diesel rated at a storming (haha!) 28 HP. Now here’s the thing, at 1.5L and 28 HP that engine is practically the poster child for “understressed”.... enter turbochargers:

It seems the engine takes ~5-7PSI like a champ at 2500RPM leading to a near ~10HP increase.... stock compression ratio is 23:1...
Anyone know about adding turbos to mechanical injection diesels? whats involved in altering the fuel flow rates? How likely am I to blow this up?

I don’t know much, but lurking on the diesel 80 series forums seem to indicate that your biggest worry is making sure that your pump is adequate for STOPPING fuel flow to prevent a runnaway situation.

And if the fuel pump should get stuck in the open position anyway, always have something to block the intake, like a CO2 fire extinguisher or a frying pan covered with leather/vinyl (because air-tight seal).

yeah, sorry im not much more help than that. Im guessing the trick is to make sure they are in good condition and wont jam up if the vaccum pulls the valve wide open.

huh, never heard of that happening... but then again, I’m not much of a diesel guy. I do know that this guy installed a shut-off valve on the oil line to the turbo so that if the seals went and it was blowing oil and running away that way he could shut off the flow. (the pics are from a dude who used an old Saab turbo)

just thinking about it again, and i guess that *IS* how a run away could happen isn’t it? I was always thinking of run away in terms of extra fuel being introduced via leaky turbo/seals and then the injection pump, being mechanical, just does it’s best to keep up and keeps feeding the fire.... but if the pump itself were leaking through extra fuel then it could turn into a run away pretty quick...

I thought the engine actually burnt lubricating oil from the turbo so shutting off the fuel wouldn’t actually stop the run away. One cure is to drop the clutch in top gear and (hopefully) stall the engine.
