Nope, the load the dyno put on, that's where she held.
Interesting.
And 1800* EGT!!! That's a tad warm! Was that with just the #2 or with the NOX? That water/meth injector you've been talking about should help. But you already knew that.
Did you just dyno or did you run as well?

Just Dyno'd. In a 1/4 mile run the EGT's hit over 2K. They actually peg the gauge about 3/4 way down the track. Yeah, I know it's warm, that's why there's a new turbo coming. And yes, that's with NOS. There's not enough NOS to clean up the smoke. This thing with these BIG injectors looks like an old time locomotive rolling down the road. Kinda fun though. Been looking for Terry cause I know he drives with his window down.
Exaust Gas Temperature. From the numbers I'd say that Todd had his thermocouple installed pre-turbo. I'm not sure about his app, but in my Cummins temps above 1300* can cause bearings to seize. Needless to say, EGT's are just as important to monitor as Boost.
I'm guessing here, but Todd's next most likely mod is either o-ring/fire ring (to handle high boost) or dual CP3's (to feed those Stage II's).
Thought you had V8 Windsor not a I6 300 stump puller. j/k
To monitor EGT's all you need is a pyrometer kit. Drill and tap your exaust manafold a couple of inches above the collector for the thermocouple (most likely 1/8"NPT but could be 1/4"NPT) and wire like any other gauge. Get two and you can monitor both banks. Or two thermocouples and a switch.
Add in a vacuum guage and you've got excellent tools for monitoring your engines health.
You obviously have not yet had the experience of meeting my beloved Ford.
She's a 79 F150 4x4 with a 351M and lots and lots of custom parts. Ask Todd about my battery hold down...he's in love with it.
The exhaust manifolds are still on it, but shortly thereafter the exhaust kinda goes everywhere as the entire exhaust system has had years and years of that Missouri road cancer applied. Let's just say that you can hear me coming long before you can see me.
Exhaust temp kit? Oh please. First methinks getting all of the exhaust flowing in one general direction would be a priority. I still haven't decided if I'm doing a full rebuild or just pulling the heads this summer.
My kids will be out here 03 July, and I intend to have some fun with the old truck while they're here. It'll do my boy good to get some grease on his hands.
Yes, pre-turbo. For the 6.0L, 1250* is redline, but when I go above, it's for very short duration and it doesn't heat soak in that quickly. I give her plenty of time to cool. Next mod is aftermarket boost gauges. Yes, two. Drie Pressure and Boost Pressure. Want to see how well matched I can get the turbo. After that, this fall, will come turbo #2 for a sequential setup and some 275cc injectors to help. Stepping up from the current 225cc's.
I don't need the dual CP3's. I get plenty of fuel thanks to the FASS 150/150 and Return Regulated Fuel System. She holds 80psi fuel pressure just fine.
The fire rings are coming too. Hypermax makes them for the 6.0 that don't require machining of the heads or block, but I'm still not sure those will be for me. I'm looking for a shop not too far away that can machine the heads for me as I have a spare set. Actually, I have a whole spare engine.

I've been lurking long enough to be aware of some of your "shadetree engineering" parts such as the imfamous 2x4. Hey, I couldn't resist a little poke after the last "real" truck comment.

I hear ya on that one. There are times I think the only thing holding my sheetmetal together is the dirt!!

Hold on now, you want the exhaust to all flow in the same direction!?!?!?! I'm kind of in the same dellema about a rebuild. I'm in short supply of 2 of the 3 important ingredients, time and funds, desire to do the job I've got in buckets.

Grease under the fingernails is good for the soul!!

I still plead innocent. I bought a well used truck a bit more than a year ago. It came with said "shadetree engineering" installed.
I've got lots of plans, but as you mentioned, time and money are always the issue. As bad as my truck looks (and sounds...) it drove me to Phoenix and back....moved me into my house...and has done whatever various chores I've needed done. A few months ago, I took a tour of half of the state one weekend, and she just did beautifully.
While running on six and a half cylinders no less.
I should have it back on the road this weekend. To be honest, $3 gas has been the issue this summer. I'll get there.
(...and I still say that Todd is just jealous... )
Glad to see you posting more often, and feel free to fire shots at will. We gotta have a little fun.

Smart. So many don't consider drive pressure and wonder why they blow headgaskets.
Want to see how well matched I can get the turbo. After that, this fall, will come turbo #2 for a sequential setup and some 275cc injectors to help. Stepping up from the current 225cc's.
Compound? Has anyone considered duals, as in parallel? One dedicated to each bank? I'm presuming that since Banks has done this with the Duramax it is also feasible on a Powerstroke. Depending on plumbing clearances of course.
I don't need the dual CP3's. I get plenty of fuel thanks to the FASS 150/150 and Return Regulated Fuel System. She holds 80psi fuel pressure just fine.
Delivered psi looks good. But, what is the rail pressure like at WOT? At the power range your running your probably not having an issue with starving the injectors at high rpm's.
The fire rings are coming too. Hypermax makes them for the 6.0 that don't require machining of the heads or block, but I'm still not sure those will be for me. I'm looking for a shop not too far away that can machine the heads for me as I have a spare set. Actually, I have a whole spare engine.
No machine work for fire rings? Sounds more like a reenforced performance headgasket. how much boost is this supposed to hold I wonder?
Has anyone developed a bolt on cam/gear to deal with the gear backing off under high rpm's?
