Update
Couple of things this round.
First I've been making some orders lately. One of them was for a Dynamic Timing Advance kit. The VE injection pump on my cummins has a timing advance function that increases timing with increased rpm. The little device that controls that has a limited travel distance, this kit merely gives it more space to travel allowing more range of timing advance. So what this means is that I can return the timing back to factory numbers for better low end and this kit allows more internal travel to allow more timing advance on the upper end where it's more useful. I heard about this on 4btswaps, did some research on the bomber sites and decided I wanted to run one so I picked one up from
M & H Inc. - Dynamic Timing Device.
It's a pretty simple kit, just a spacer really but it costs $105 shipped. I'm hoping with this, hotter injectors, a fuel pin and more tuning that I'll be able to work that HE351VGT turbo I'm still planning on throwing on in the future. This kit goes under the KSB unit on the side of the IP.
Since I'm odd, I brought this with us on vacation this weekend in the thoughts I might have some free time to play on the truck. I did get a block of time and it was fun wrenching in perfect sunny weather at a beach house (beach front) with the sound/site of the ocean in the background. There was something peaceful and enjoyable about it.
Getting to the two little T-30 torx head screws was a little challenging due to the steering pump being right there but with a torx socket and my small 1/4" ratchet I was able to get in there and loosen them up.
This is what comes out, a spring and a shim. Some diesel fuel comes out but not much and it doesn't drain the pump or anything.
This is how it goes back together with the left side against the KSB and the right side against the IP. So left side starts factory shim, kit shim, factory spring, kit spacer and o-rings.
With some careful hands and no gloves because I needed the dexterity I got it all installed.
I re-timed my pump to 13.5 degrees and did some IP tuning. I gave it a little more power screw, adjusted the star wheel, adjusted the AFC, and the smoke screw. I started it up and it worked! That's always a nice result. We went to take it for a drive to the store and I was getting an error code on my tranny controller. Basically the TPS was not reading or it was intermittent. I'd take it off and rotate it and it would read voltage on the controller, I'd put it back on and it would just stay at zero when I moved the throttle. After some head scratching I figured out it was the way the TPS was mounting now causing the internal arm to not contact the wiper area when it was rotating due to it being pushed just far enough up. I found some perfect washers in my misc. spare parts in the truck and the first attempt was with tape. That didn't hold it well even for a temporary test so when we ran to the grocery store I found something that would be easy to mod but strong enough to keep some tension on the washers. As luck would have it there were even holes spaced just perfectly in it to use my existing screws.
Yup, a plastic 33 cent ruler.
It held well on our return trip home and fine this morning to work. I think I'll cut something out of aluminum to replace my ruler fix before I take it to any car shows.
The re-tune and timing kit gave me more grunt down low and more pull up top. The turbo responds faster and while I do get a puff it doesn't haze as much. We believe I'm now around 185hp and 395 ft lbs. Someday I'll have to put it on a dyno to get hard numbers. Probably not until after the turbo upgrade though.
A couple weeks ago I found my air filter split. I taped it to get a few more miles until I could do some research and get a new one.
I believe that it got a crease in it that made a weak point and with the motor rock I get on shutdown it eventually just split it. It must have be hitting the fender well the way I had it mounted just enough to create the stress and eventually split it. I did some reading to see if I could find anything else I wanted to try and so I went back to looking at the fluted donaldson style filter but at $100 plus for a universal I kept looking. Another Amsoil was going to be $70 plus. I per chance stumbled across R2C performance filters and started to research them. They are kinda new in the automotive performance market but have been around for many years supplying the military and dirt track guys.
R2C Performance
I couldn't find dimensions for their conical filters anywhere so I called them up and talked to Ed (I'll have to check my notes). He was confident, relaxed, and helpful and asked what kind of an application I was fitting one for. He liked the swap and asked for the space constraints where I was putting my filter so that he could get the biggest one in there. Since this was a new application for him he cut me a great deal and sold it to me for $50. When we got home it was on the front doorstep.
Part No. C010517
It's a dry conical and has these dimension:
7.25"(big end) x 5.34"(small end) x 9.5" overall length 4" inlet
I adjusted the intake piping to space the filter off the fender well better and I'll need to make some mods to my heat shielding so I took it out for now. The filter cage feels quite a bit stronger than my previous Amsoil filter so for durability I think this will hold up pretty well. Under the same tune I gained 2psi max boost on my turbo from better air flow. I haven't been wheeling in way too long but now I feel better about heading out with my engine protected.
The last thing I've ordered recently was a complete swap kit for the 14bolt from Ruffstuff. There were some things missing (diff cover), somethings to be exchanged (disc brake brackets) and some things to be returned (I bought the antiwrap plates but not the kit so the bushings, bolts, and additional plate need to go back). I also pick up another heim as a spare. The website is new and has a few little fixes needed but I talked to Dan and he's on it. When I opened up the box and found the different pieces I called and talked to Brian and he said he'd have the right parts send out the next day and a return label for the others. I understand there are hiccups from time to time and it's the how a company deals with making things right that makes it important.
I've redone my hood liner. I cut them out to fit in the recesses and glued them in. Visually I think it looks better and it still cuts the noise down.
So now I'll need to turn my attention to the axle, wheels and tires.
