Another 1.2 hrs on the dyno with 80mm injectors, pulled 420 FTLBS@1900 rpm and 200 HP corrected at 2500 rpm. Needs more air.:)

That engine sounds absolutely perfect. I don't remember the ones we had running that smooth. Possibly, but we seldom ran them wide open on pumps or light plants. The one on our genset was governed to voltage and frequency and never changed. The pump ran just fast enough to deliver the flow we needed. One of the guys decided to horse around a little by blipping the throttle while I was washing equipment with a 1 inch hose. It took everything I had to hold on, even for a few seconds. I still have many fond memories but they're pretty rusty. You may have noticed that I have a great fondness for these engines.

That's awesome.:) My first exposure to Detroits was at the age of five. My dad owned a small logging company, Hayes HDX 12V71 and two skidders with 4-53's.:) He too loved Detroits and in the day pretty much everything was Detroit. It was those memories that started this Detroit obsession for me.:) Being I drive one daily, I'm always getting my fix.:)

Nice work there. The GMC dealer I worked at had no engine dyno. Had a chassis dyno for the big trucks. Used it to break in inframes and injector changes for extra horsepower. Real noisy to roll a big truck. Had to watch drive tire temp also. We did get big power out of the Silver 92's. Looking forward to your injector change.

Thanks for braving the cold to get us this video! I think it got to 44°F here and I about froze to death. Lol. God Bless

After watching Jimmy on your dyno a couple of times I think I finally understand your one hour dyno break-in - it's tough to put that kind of sustained load on him in your truck. But it would be fun trying, huh?😎

@detroitgarage9430 2 ай бұрын

Very true, the schedule calls for 2hrs of 80-100% loads. For the break ins on my truck hit the mountain hwys and do several loops. Going to set it up in the shop now so that will save the setup time each run.:)

adding a charge air cooler will drop the EGT's you won't see any horsepower gains.

Dang 25 psi is decent, you may have already said it, but what you get for peak EGT’s? It was smoking some, but by no means rolling coal, so that’s nice!

@detroitgarage9430 2 ай бұрын

It ran around 900 degrees at 100% loads.:) Some smoke, but just a haze.:) Next injectors will be 9E85's and that will be interesting. I'll run it first without an intercooler to see how much smoke there is.:) Will be adding the Intercooler after that.:)

@clayclifford53 2 ай бұрын

Not bad at 900, you got some temps to spare…and intercooler will be interesting to see what happens with smoke and egt’s. What injectors did you run in your truck a few months back that ran like poorly?

@detroitgarage9430 2 ай бұрын

@@clayclifford53 Should be interesting.:) I swapped in a set of used 9G90's. Ran real nice for 5-10 miles or so before one tip took a dump.:) I've replaced the tip with a new one, so see how they run now on the dyno.:)

Another terrific and informative video, question…. You pointed me in the correct direction for my 6V53T adapting a GM NV4500 to it. Now I may be getting 4-53T, would that be the same SAE#2 from phoenix to adapt a GM NV4500 as well? Thank you.

@detroitgarage9430 2 ай бұрын

Most likely, but some 4-53T's did come with #3 housings, so you'll have measure it to be sure.:)

Knowing CC per injection, rpm and power available should give a direct result in grams/kw/hr for BSFC. Boost is looking decent........still a long way to go to 42psi ( like the modern heavy truck engines) Interesting to see how boost tracks with injector sizes going up. However, for its capacity, it is making good torque, relative to boost.

@detroitgarage9430 2 ай бұрын

True, showing progress in the power bumps. The 9E85's will add another 20-30 HP, so we'll see how it responds.:)

@raygale4198 2 ай бұрын

High boost doesn't get the same result as a 4 stroke engine, fit a pressure gauge to the airbox and see what true charge pressure is. That blower becomes a hindrance at high outputs. On high spec 92s and 149s the blowers were fitted with boost operated bypass valves.

@detroitgarage9430 2 ай бұрын

@@raygale4198 Thanks, I'll have the airbox pressure gauge for the next run.:) Right now I'm running the T blower, but will compare the N and bypass blower.:) On my truck I have an N blower that's bypassed at 10 psi.:)

drill the exhaust manifold to get a temp per cylinder
