builtby shieds looking at what inj. size to run with it

RSWORDS 12-22-2008 06:04 PM

Your not giving us alot to work with here. :D What all has been done to the pump? AFC mods? Fuel Pin? Fuel Screw? What size head and rotor? Cam Plate?

New Era 435's are a good injector that can support 400HP maybe 450 if your not towing

6x16's are a good power injector. gonna need some air to clean the up though.

Oh and I almost forgot...

:hi:

Okay.

Is it on the truck? You cant set the full power screw w/o it on the truck so that you can watch out for run away. Temps at WOT? Boost?

Turning up the pre 94 Ram diesel injector pump

Snaged this from a post by Cowboy Customs

What is a runaway?
A runaway can occur while turning up the fuel on the VE injection pump, the reason they run away is that the control collar can't move far enough towards the "defuel" end of the plunger (making the spill port area smaller), and the backpressure in the spill port becomes high enough that engine speed goes out of control. This is why they will idle OK but then hang at high RPM. At low RPM there's not enough backpressure to start the runaway.

How do u prevent a runaway?
With this procedure you can help prevent a runaway better then the old method of slow increments.
With every 1/2 turn of the fuel screw, snap the throttle. IF the throttle hangs in the upper RPM's before coming back down your on the edge of runaway, or if it will not comeback down to its prior RPM, back your fuel screw back out at least 1/2 turn.

How do u stop a runaway?
Remove an intake somewhere on the engine, if your doing this by yourself, open the intake on the driver side of the engine, if 2 people, remove the intake at the turbo and give your sidekick the board to cover the inlet into the turbo. What your doing is choking the engine should the runaway occur. This will the engine down.
You need to keep a sturdy board handy while your turning up the power, after all u dont want plywood sucked into your motor at 6000 RPM's do ya?

This is runaway, and thats how u can try to prevent it, and stop it. Still want to turn up the power??
