Yay, more fun. Actuator, none, anywhere, that Cummins can find!

Sooo, anyone put a bigger turbo on one of these that has an actuator they want to sell!?

 

for the money, id go to a banks dealer, the banks aftermarket wastegates are on sale right now, you can get the banks quickspool housing with it for 350 bucks shipped!

 

No doubt, that would be sweet. But this also isnt my toy, its what hauls my toy, so it only has limited funds on how cool it gets! Plus, looks like (have to put it in and test) I have a good one here now, for free, from a buddy running a hx35 variation on his mustang.

 

whatever works. so whats your toy?

 

Keeping this updated:
Tried another actuator, worse, went to 12psi. OS swapped back in the weak 15psi one, and threw in the edge elbow. Much better. Then wired in the comp box, without the pump wire tapper, set it on 1-5, drives great, boosts to 23psi right now. Backed it down to 1-3 see if the mileage improves. But, pulled ~4-5k over 11k ft pass, pulled great, topped the pass at ~65, and only half throttle.

Plans now, turn off the box, take out the elbow, adjust the actuator to get it happy, back at stock settings. Then back in with the elbow, tap the pump wire, and be good to go.

As for the toy:

 

e, my nieghbor down the road has one of those rock crawlers, he taes it to the 4x4 jamboree in Indianapolis every year.

 

So boost elbow stuck in, and comp box set on 1-3, with pump wire untapped.

Varied on towing from 12-14.5mpg, however unloaded is up to 18.5, up from dea-on-always 17. Boosting at 23 psi. Playing with the actuator a bit more, and se if I should be boosting more or not. Then Ill tap the pump wire and call it done.

On the hard start, appears either fuel pressure or apps related. If I do key on, pump throttle, then bump the starter wait for 4psi, starts right up. However if I just pump the throttle, hard start still. And sometimes if it just gets the bump to 4psi, hard start. so thinking 12-15 psi is just a little too much pressure for the vp44 on start up.

Compared to a couple months ago, runs great!
