Not So Pro 3

Diesel run better a bit hotter. They like 209-210. Many thermostats are at this setting. The warmer the fuel before combustion, the more complete the burn.

then why are duramax thermostats at 180 and 185 and why are there 2 of them ?

Cummins swap?

lol no i not buying a gold box

I'd rather error towards cooler than hotter especially when towing heavy.

with gooseneck and tractor i am about 24000 pounds maybe a touch more

The new turbo technology is far superior to the old

Yup, it does the work of two, and ya only need one.

That POS Toyota Surf would hit 900C (1650F) pre turbo under load so fast when i first got it that i'm surprised it lasted as long as it did.

Multiple mods later and a sustained 600c (1100F) was possible. Learnt a lot from that turd.

Time for another one this time with a 1uz.

Duno know and duno know.
Never paid Durajunk much mind. Made by Izuzu.

Gold box?

about 400 pounds lighter than the cummins or power stroke also

Nuh uh,

Gold box?

parts are 3 times as much as duramax

Left. Boost.
Ctr. Water in and out, switchable to externally cooled oil in and out.
Right. EGT.
Rocker switch for water or oil.

Result. 1KZ-TEs are the devil's engine.

The 1uz will be just fine with 37's lol.

Definitely wouldn't want to run any hotter. At the same time the efficient the more power is being put to the ground instead of wasted heat out the pipe. Nice and easy 2200 RPM with a warm diesel wont hurt a thing. I6 like the warmth a little better. the V8s are a bit different.

Most diesels are not afraid of weight. And I have/had both. Also had a Ferd 6.6l I6. That's about it though.

Lol mine just lights at 2,200 rpm. Highest water temp I ever seen was 210 up a 6% grade towing. No hotter for me. I got plenty of power so not overly concerned about what little is to be gained. Chit cost to much money to blow up.

heavy towing you need the weight savings to stay under limits
im getting about 14 out of mine when pulling a trailer

lol about the same as mine likes to shift about 3000 when playing

That's not bad at all. Last time I paid attention to milage I was getting 18 unloaded.

I reckon that's the best/worst thing about an egt guage.
You can see how much heat your adding trying to hold a given speed, but just a smidge lighter on the pedal costs hardly any road speed but runs way cooler EGT wise.
So then you're always looking at that instead of the road....

Got mine limited to 3,800 right now. But that's with smith brothers pushrods and comp cams 910 springs. Good to about 55psi of boost. I try to keep it under 50 pounds.
