Since you spent some time with a bunch of diesels, what's more desirable as far as trannys go? Manual or auto?
I am thinking more and more about a European import.
They come in both flavors. Manual (5spd) and Automatic (4spd).
And of course that's not a speedo.
That would be the tachometer.
And this is a speedo.
Hope it have a lasting effect on your memory now.

Based on what I remember from my old HDJ80
Green comes on at 3psi
Red comes on around 15psi - factory overboost warning.
You'll not likely see red with the factory turbo setup and a stock tune, the fuel pin in the boost compensator defuels as it approaches the factory boost limit. With a stock setup seeing the red light indicates a problem.To be clear I dont ever want to see red? What is the max boost set by the factory.

Factory boost level as per the fsm test is 8psi, however the test is performed stationary with no load, so in real world driving you might see a bit more than that.
The limit of the stock turbo is around 15psi safely and efficiently, above this there is the risk of failure and because it's operating way outside it's efficiency the air is being heated a lot. With some turbo upgrades, a 1HDT is quite happy with a lot more than the factory boost, with a good standard fuel pump and injectors you run out of fuel at about 25 psi and 140-150 rwkw with associated mods ie intercooler, exhaust etc. I made 154 and 580 rwkw and rwnm at 25 psi with a modded pump, airbox, intercooler etc
On a performance note, by swapping the standard exhaust for a 3" turbo back exhaust (including dump) I went from green light coming on at about 2k rpm down to around 1400 rpm. Big drivability diffence.
Sorry, for some reason I didn't see that. Given the auto, it's possibly why the boost builds a little later, could be to do with the stall of the converter or something.Im 3" equipped
The one nice part of all the diesels is they never seemed to run out of power even at the top of steep pulls.
Sure... Right up until you install a pyrometer
You DO have a pyro, right? Tranny temp gauge is a very prudent install as well if you don't have one yet.
Cool truck. My 1HD-T is running at about 16 lbs boost with a 3" exhaust, so I see that red light all the time. Not worried.
Since you have the exhaust already, an intercooler is a huge upgrade on these motors. Even better if you can pair it with a G turbo and a Wholesale valve body. Like Enigma, I have none of these things
After seeing first hand what this drivtrain is capable of Im not a bit concerned because it will never see that hard of life.
So it's for sale then?As it settles in Im not sure I didnt bite off more than I can chew with my upcoming white 80 remodel.
