VE pump tune up

Recommended Posts

Hey gang. 

 

I've got a 1992 Dodge here that I've just installed injectors into. DAPs (5 x 0.011) +30 HP 1st Gen injectors. Now knowing what I do of tunning I know this pump needs a bump in timing. @JAG1 gave me the wrench for doing the timing. Now I need to know which way advances the timing. I'm thinking it turn it down as you stand at the driver's fender. 

 

It taps out at a mere 75 MPH and that all it will do for speed the owner would like to see more out of this. I'm thinking the governor spring is shot and not pulling the fuel pin as much anymore. I know I could opt for the 366 governor spring but that is a PITA to install. I'm thinking of just turning up the fuel screw more to compensate for the shortcomings. He's an older gent doesn't need a race truck just wants good power.

I never adjusted the timing on my old 93, but the Denny T fuel pin and pump adjustments went a long way, low end and top end.

Hmmm.. Food for thought.

 

With these +30 HP injectors, it's just a tad smokey. Idle seems a bit low as well. Just want to add a few degrees at most. I'll have to dig the internet and see what I can find. Actually, the timing to advance turns the pump upwards towards the block.

 

Denny T fuel pin is a for sure of extra power they have some steep profiles. 

 

This pump still got all the smog caps on the adjustment screws. Untouched for 260k miles.

I can't remember which way to retard/ advance neither. :shrug:. I hope that wrench helps anyway.

I haven't done any research on this but I think the pump needs to turn CCW while looking from the front of the motor.

 

50/50 chance, right? :lol:

@Mopar1973Man rotate the pump towards the head. Additionally each tooth is if memory serves 5°. If you don't know already the timing mark on the case to pump should be visible, it looks like a chisel punch.
