Somewhere on Mud someone posted a Mad Max meme, “A343F: 2 hp enter, 1 hp leaves!”
Hmm. A442F here but if I had dyno access and the required disposable funds it would be interesting to run mine now and after I install the Extreme Valvebody I have coming from Australia.
Im a bad reader, thanks for clarifying

It sounds like we might have a lot more Utah data coming shortly.
Some 6bt diesel power, stock 80 power, SC 80 power and turbo kit 80 power. SO lots of comparable data at 4000ft of elevation....

Sounds like its time for the mud R&D slush fund to be setup..... I'm sure people would chip in here and there for beneficial tests such as these.
I'd not get too stuck on the drivetrain loss stuff given this truck appears at least to me to be running larger tires than stock, also not sure as not seen it mentioned but what's the gearing?
Its my understanding that the dyno computer corrects for tire size, gearing, speed, rpm, etc...
Well it will use either an inductive pickup for RPM or manually set by the operator but I'd doubt on that dynojet it's correcting for tire size verses OEM or gearing as they'll select the only gear they can lock and take to redline (2nd would make sense although L would lock but not be close to 1:1 ratio) Dynapak dyno would require then operator to enter a final drive but the dyno used wouldn't

This is correct.
The dynojet calculates hp from actual torque at the drum using an inductive pickup clipped onto the ignition lead to get RPM.
The only correction would be to correct to standard temp and pressure. There will be no correction for tire size, gearing, etc. but the only thing that matters is the delta between the pre and post turbo numbers. As long as the same truck and same dyno are used you will have comparative numbers.

Dan if you’re actually interested. The place that might be dynoing all the other 80’s is Turbo Lab Racing in Orem. They have a Dynojet 424 AWD just like the one Joey used. They have a price of $95 listed but maybe we can get a package deal of sorts?
Do it! Everyone wants to see what a bus tranny can do......
Yea I may have moved the air temp sensor while using a Dynojet nearly two decades ago during a magazine shoot out to umm aid with numbers for our car, don't recall if it was the same shoot out or not but we also ran C16 in a hidden 1 gallon gas tank use solenoids to um help our pump gas numbers a little
Totally agree with the same truck required for the delta's in the numbers, hopefully similar conditions weather wise as well.
Seeing these results kinda makes me want to chuck my 80 on my dyno to see what it makes
I HAVE seen what a bus tranny can do; hopefully whatever Dan is involved in is more "technical" related....

Maybe its time we get you to move to Utah.I just paid double that
It may not be worth the discount. This was taken about 45 minutes ago.
