they should be good for right around 75 hp. That will of course depend on the builder and how much care they take, but for the most part you will get the rating they are.

Also gotta say the turbo is much nicer at sea level. If you punch it at 60 the tires just lite up. Spool is VERY quick and smoke levels are low regardless of what level the tuner is on. Now I just have to come to terms with the fact that I live in stupid Colorado at stupid 7000'........ not mad about it at all.... Mpg's for the turbo are pretty much the same as the hx35. They really don't change regardless of the vanes being set to wide open or running at 9cm. MPG's still follow speed closely. 55 23ish mpg, 65 20mpg, 75 17mpg.

Here a very short video of the truck at Sea level ( well closer to 1500' at that point it was even cleaner at sea level), 0% throttle to %100, not rolling into it, just right to WOT. i cannot believe how clean these 7x.009's are at sea level

Headed out on a 1600 mile road trip, I will able to do some mpg testing.

ouch.

Should have done this awhile ago. but I have started to zip versions before changing. I have also added a change log starting at this point. I added the links to the Article so people can see the log.

no idea, can't be any worse than the orielly filters I typically run. At $4 a pop or whatever it works.

sell what you have and get the right block? That seems like the easiest way to go about this.

hoping / praying for the best man.

Great to hear! Sometimes a plane ticket and some diesel will get you a good deal and some good stories on the road.

Also I updated the article, Can someone look it over and give some pointers? suggestions on the vague/limited wiring and config section I added. Is it enough? should I do more indepth on how to wire the arduino? http://articles.mopar1973man.com/general-cummins/34-engine-system/480-he351ve-vgt-standalone-turbo-arduino-controller Mike, Any suggestions on how to generate some google traffic from the title?

Anyone think of videos you want to see that I can do?

You could troubleshoot the 1690 code by putting a new sensor in. You could also save a bit of money if you trouble shoot with the article. either way works fine. However you p0216 code is almost always a vp44 that is getting tired.

Yep as cowboy said, you can just buy the stuff I have listed in the first post. Upload the code set I keep updating, and be off to the races. You should be able to read through most of the code as I tried to make notes. Everywhere you see "//" is a note. today was the first time I really got to lay into the throttle pedal and hold it. The truck screams compared to the hx35. I am pretty sure I am well north of 400 hp I however don't think I would recommend the vgt to someone that doesn't like to tinker. With about 30 minutes chatting with my you could successfully tune the turbo pretty good, but it does take someone wanting to learn, tune their setup.

glad to hear things are going good for you two.

I prefer the hat trick attack on rust, Oil from blowby vent ATF from tranny lines and some diesel from a leaky water drain

Yea, can you think of a better name for the article that might get more attention? Same for the swap article?

Yea I would assume they have a pretty in depth map for it. I wonder how far off base I am haha,

Mike that's not really fair. I know you crawl under there with a toothbrush.

I think it is ~ 3psi - 5psi difference in effective boost due to the loss in atmospheric pressure.

Thankfully I can tune the curve to the "normal" altitude and temp. I would love to talk with a Cummins/Holset tech about how they tune the turbo.

I live at 7000' so it's not to far off. My hx35 ran about the same at 75 mph. Sealevel should drop that by 100*f if it acts like my hx35 did at sealevel.

depends I have a couple different profiles that are assignable via an in-cab pot. I can choose from 3 curves currently low mid and high Low or towing curve will put me at atleast 5 psi at 55 unloaded. Loaded I am sure that would be closer to 10-15psi ( no extra fuel run except for the injectors) Mid curve I see ~3psi at 55 unloaded ( fueling should be set to lvl 2 on the quad or canbus plus timing only) High curve performance mode I see 0 psi at 55. ( I can runt he quad turned up on this mode) Keep in mind my curves are based on the amount of fuel I am putting in rather than how much psi I want. The tuning of the turbo works better if you do this. So even though I have 0psi cruising at 55 in Perf mode, If I step on it the fueling I have will light the turbo quick and build to the max boost WITHOUT overspinning. If I use the towing curve with all my fuel turned up it does make for a fun ride, however you push the turbo WAY out of it's map, I would be blowing hot air by 2000 rpm. I am able to do this since I am watching my TPS values and adjusting the vanes from there. // TPS_range calc process if (ThrottlePosition <= 25) {TPS_low = true;} else {TPS_low = false;} if (ThrottlePosition <= 45 && ThrottlePosition > 25) {TPS_midlow = true;} else {TPS_midlow = false;} //{TPS_range = 0;}// watches throttle input to increase vane position. Vane position mapping is based on low throttle input. if (ThrottlePosition <= 70 && ThrottlePosition > 45) {TPS_mid = true;} else {TPS_mid = false;} //{TPS_range = 20;} if (ThrottlePosition > 70) {TPS_high = true;} else {TPS_high = false;} //{TPS_range = 40;} if (TPS_low) {TPS_range = 0;} //supports low throttle cruise. if under %25 don't change vanes if (TPS_midlow){ if ( BoostPressure < 5) {TPS_range = -40;} //it will try and spool the turbo if tps is 25><45 - numbers decrease vane size else if ( BoostPressure < 10) {TPS_range = -20;} else {TPS_range = 0;} } if (TPS_mid){ if (BoostPressure < 10) {TPS_range = -20;} else if (BoostPressure < 20) {TPS_range = 0;} else {TPS_range = 20;} } as an example you can see that I am making TPS_range range between one cm smaller , -40, to one cm bigger ,40. Then in my vanes calc section I add that TPS_range value else if (turbo_rpm < lit_rpm) { AntiBark = false; vane_position = map(turbo_rpm, curve_rpm[4], lit_rpm, turbo_curve[3]- TPS_range, turbo_curve[4] - TPS_range);} so if I am cruising with turbo rpms at 50,000 and I step on it the vanes will actually close some if boost if lower than 10psi. However if boost is up above 30 psi I will open the vanes some.
