been doing a lot of playing around with the ve pump in my vw , and a thought keeps occuring to me , instead of a the 3200 rpm spring , is there any reason why the shaft and linkage out of a vw ve pump couldn't be used in a cummins ve pump ?
assuming the govener weights are the same in both pumps , then the stock vw defueling level would apply , and in stock form it is rather gradual , starting around 3800 rpm , in in full effect around 4200 - 4400 rpm .
with a bit of shiming of the 2 sets of springs that can easily be changed to around 4800 rpm , with 6000 + rpm possible .
i know the valve train on a cummins needs to be tweaked for the higher rpm's , but even the stock vw settings would be a improvment over the 3200 spring , which some people claim doesn't always start to defuel at 3200 , but sometimes much sooner .
( the ve pump i'm thinking of is off of the 1.6 idi turbo ..... other may vary )
just a thought since depending on where you look , there can be literally piles of vw parts going for next to nothing .
