Throw those kind of EGTs at a diesel and good luck getting 10,000 miles out of it before it implodes.
What in the heck are you talking about m8?
I learned to drive on a 1966 Diamond Rio with a 335 Cummins that had more than a smidge of advance and a smaller than stock “button” (bypass orafice) in the pump. 5x4 transmission. It was 1979, and I was 17. It was a hot rod for a truck. No ECU, no DEF, none of that BS.
seat belts? LOL.
power steering? LOL. Keep your thumbs out of the spokes.
It didn’t even have brakes on the front axle. And yes, completely legal in that condition.
The word from dad (he and grandpa owned the truck and the company) was “no smoke, and don’t drive the pyrometer too far above 1600F”. He was
constant about the“no smoke” part. It was was the larger Issue. Load a Diesel engine up with fuel and way too much cylinder pressure is generated, along with soot from the incomplete combustion. Ya gotta let up a bit before you crest the hill too, as running downhill, throwing a bunch of cold air onto really hot parts (valve stems, seats) is not a recipe for longevity.
I was taught to drive it like there is an egg on the pedal (a story in itself), and don’t build too big a fire in it.
On a diesel, 1600F is fine. 2100F is death. There’s an art to it, and it’s all about your right foot, though the ECU does it all for you today, and you can just stomp on the pedal and let the computer drive. It won’t let you “roll coal” without mods.
On a gasoline engine, if you’re running higher than 1400-1450F, I suspect one or more of: too much boost (Joey’s kit is 7PSI, which is fairly safe), fuel mixtures are too lean or timing is too retarded.
But it’s still about your right foot.
p.s.: I’m dropping a 1HD-FTE in a lx450, with a bunch of aftermarket (PDI and gturbo) mods. I ain’t skerd, except for the clutch in between the FTE and the H151F. Dyno run soon.
