It looks awesome Wes, I can’t wait to get out there and pick it up.

Sounds like the only place this truck is going to disappoint is rear tire life 
What was the "short" list on this truck again? Turbo, studs, IP, injectors, and intercooler?
Granted the transmission, but that won't be part of the equation for some of us.
You have me starting to reconsider my turbo choice now

Me too but there's always another truck.

overkill is under rated!
That is awesome @Thewespaul! Now Im chomping at the bit here to do my upgrades! Any word on those intercooler kits?
It’s got my GTX3582 turbo with the stock hot side and a 3” downpipe, my intercooler and intake kit, my 110cc pump, RnD stage one injectors, stock fuel system otherwise. Engine is studded with the modified 7.3 gaskets, comp 910s, and cerakoted piping.
Y’all should be getting the kits by the end of the month, the fab shop had to lay everyone off except one employee but they started on building the parts this week so should have them out soon!
That's great news Wes! No need to reply to the PM I just sent. Let's hope that it goes as planned!
Here’s the new housing that went on, hot out of the ovens.
Swapping the housing really improved the response from the turbo, picked up a couple psi and really changed the tone of the turbo, it’s singing at any rpms now.
Today we got it on the dyno to see what it would do. Right away was having issues trying to get it loaded right to get a full picture of the torque curve, the trans didn’t want any load below 23-2400rpms which is well past torque peak already so really only got about a 1000 rpms of the power curve on the downhill side of the torque peak. That made for some disappointing numbers, the best I saw was 270hp, and best torque reading was 527ft lbs. That’s a 120hp and 190ft lbs improvement on the same dyno, while real world 0-60 has improved from 15.2 to 5.8.

That's a fast truck!
So what are you figuring for crank hp? Around 350? I know wheel hp is always lower.
I was kinda impressed the numbers were so low given how effortlessly it was tugging that trailer. It's still probably three times what I'm putting to the rear wheels now

The real world performance doesn’t match the numbers at all, boost was even down to 22 psi at peak on the dyno the engine just wasn’t loading well, I wish everyone could ride in the truck and feel how this thing moves out and just grunts trailers up hills so well. I’ve got an 02 7.3 that’s got the cheap mods and tunes that was rated at 275/525 and even on the “160” hp tune this idi would easily walk it, and the Powerstroke has 130k and no heavy camper in the bed. I think this truck legitimately makes 320-330 hp at the wheels and mid 600s torque, just need a way to manually lock the trans in 3rd to get a proper reading, this just being a daily/tow vehicle were not going to go that far just to have better numbers, what matters is how the truck performs and I’m plenty pleased with the capabilities of the truck after the upgrades. Certainly won’t be going 20mph up anymore hills!

That's still outstanding! That truck is fast! And I bet you hit that 20k load up that same hill in the last video and you can really get a nice feel of that beast! I may need to delete my waste gate now......

Sometimes I'm still amazed at the power numbers that come from one of these engines with just a few upgrades (that right ones at least). This comes from six years of working on hundreds of these with stock or slightly above stock power levels.

I know the powerstroke guys usually have a dyno tune to lock the tranny in 3rd with the torque converter locked up too. Is there even anyway to do this with an idi? I don't know if you could get a 5 position chip or anything for the tcm like you can for a powerstrokes pcm.

I wish, the psds run the trans via the ecm where our trucks have a separate tcm. Only way I could see to do it without a manual valve body is to have the fipl output on a switch to fool the trans, and manual override for the lockup pin on the tcm.
