I put a 3200 spring in my buddies truck tonight and he loves it. The truck is totally different now. I also moved the throttle linkage and turned the fuel pin to the deep side and removed the nylon washer. I wonder why they didnt put that spring in these trucks from the factory? It only took me a couple hours after fighting with the one allen head bolt that holds the pump top on. That thing didnt want to come out for anything I finally beat it out with a hammer and a punch. That hammer and punch trick is one I learned on here and I have used it many many times.

 

nice, i can't wait to turn my other truck up ;-)

 

I bet they didnt put it in from the factory because they are too much. See my video the other day? that thing will make some RPM.

 

I bought a 3200 spring off E-bay some time ago, went to install it in my resealed IP and found that they sent me a 4200 spring. So needless to say the 3200 is on it's way, warranty.

Those are the mods I want do to old RAE as well...to start at least...once I actually get to start driving it again.

 

My guess is they didn't want people blasting up hills with the hammer down at 3,200 rpm....probably why it wasn't a factory option.

 

Yeah, the 'mighty reliable Cummins' might have had a much different urban myth/legend surrounding it these days than the one it's got, if they had made it an option.

 

Cummins designed our engines for longevity and economy. Diesel engines running efficiently at low RPM's have a strong tendency to travel more miles and run more hours for fewer dollars. Most of those big freight train engines you see pulling millions of tons are running in the 1,000 RPM range efficiently. Of course your end results will vary....

 

depends if your talking about Diesel mechanical, Diesel-steam or Diesel Electric. If your referring to the last one, then yeah those diesel-electric locomotives make some awesome amounts of power at low rpm. Something like 450tons 1 mile on 1 gal of diesel. I think most of those motors make around 3000hp and generate some 2000Kwh to power a few 1000Amp drive motors.

Fweww it is kind of mind blowing when you think about it . I think your millions of tons is far fetched though... most freight trains should be no more than 8,000 tons (150-300 tons per car). But one car one mile on one gallon of diesel aint to shabby.

 

Yes, a typo on my part. I was thinking of millions of pounds but started thinking about all the tonnage involved and type tons instead.

 

yeah its still amazing they can even move

 

The CSX feel god message is just that. What they don't tell you is the trucks shuttling the freight around the yard, trains shuffling the cars, loading cranes, idle time....

More like a 1:1:1...

 

here is an interesting diesel locomotive engine.....

That engine is awesome! Those MTB's were unreal fast, even these days they'd be considered fast, and they were made of wood! I'd love to have one of those tied up for sure.
I went to a water pumping station a month or so ago. They had 5 Fairbanks Morse engines of varying displacements. All 2-stroke horizontally opposed configurations. Basically the same engines they put in WWII submarines. Built in 2000 using 1938 technology. Seriously cool.
