Short ride in a turbo'd M813A1 5-ton 6x6 army truck

Cummins 855 cubic inch NHC-250, Schwitzer BHT3B turbo, 26cm turbine housing, 5" exhaust, #17 fuel button.

[@sgt.dieselellinger6461]

That's a beautiful sound of the roaring 250 Cummins diesel engine

[@Blazefork]

The M8 series are definitely the best looking units out there.

[@biffbalata1]

I remember working with the 6speed automatic transmission during testing in 1978 at APG Md. John and myself were the only GIs authorized to work on them. They were our babies. Ah, the memories.

[@m809er]

Were you guys driving on a test track?

[@ajax1137]

I'm on SS and followed your build. This is the sound of Liberty.

[@socaljarhead7670]

As reliable a vehicle (of any type) that the Marine Corps ever fielded.

[@m809er]

My coworker said the Corps was still using them when he joined up in 2003 and didn't let go of them till about 2011. A 40 year service life speaks volumes about the trucks' build quality!

[@socaljarhead7670]

They really were incredible. Much better than the 923s, and those were pretty dang good aside from the CTIS which gave some trouble on occasion. Many a young Marine actually learned how to drive stick on the 813. It was that easy to operate. If you got a 5-ton stuck somewhere, you shouldn’t have been there in the first place!

I miss driving my dad's m35-A2

[@timethious54]

Next project for mine, the turbo. Then a three stage jake 😊❤

[@m809er]

The two best noise makers! I have both on mine and they are my favorite additions 😊

Please make more video

[@USNENFTS]

Is this the large cam version of the 250?

[@m809er]

This is the small cam version (2" cam journal vs 2.5"). The Big Cam engines came in the M916/M920 family of trucks

[@USNENFTS]

@@m809er I may be getting a M813a1 here in the future and The first thing I wanna do is turbo it. I’ve read that the intake crossover doesn’t clear the hood,Did you custom make your intake pipe or just route it a different way? I see you have a second air filter housing on the passenger side. Also, did you source a different exhaust manifold? Looks to be a few out there that allow the turbo to bolt on.

[@m809er]

@@USNENFTS The factory cross over doesn't clear so a custom cross over has to be fabbed up or cut through the hood like @bobbed_deuces_wild did to his M813. Go to steelsoldiers.com and search for thread 'My M813 gets a turbo' as well as other turbo build threads. Guys have been adding turbos for at least 10 years so lots of good info there.

[@USNENFTS]

@@m809er okay will do! Thanks man!

[@EricTheHoly]

@m809er3 how much did it wake up the old girl? Any help with top speed?

[@techman9634]

Whats the top speed in this baby?

[@m809er]

They say about 72 mph

[@hisaddle]

That is cool. I know just enuf to be dangerous. How much boost? What is the change in pressure in the combustion chamber? Just curious. I have owned two dueces and two M923A2 and still belong in the MVCC in colorado.

[@m809er]

14.5 psi is the most I've seen. No clue what chamber pressures are...

[@sethtaylorm925]

What all did you have to change?

[@m809er]

Everything on the exhaust side of the engine, the intake side of the engine, the coolant reservoir location, and lots of little stuff.

[@sethtaylorm925]

@@m809er ok, I'm guessing might be little easier for mine, because I have Cummins 250;in m925, I'm looking into putting turbo on it. Thanks

[@m809er]

@@sethtaylorm925 , on a 925 you have enough hood clearance to use a factory Cummins crossover pipe and aftercooler unless you want to use an MRAP intercooler or go non-intercooled like I did.

[@sethtaylorm925]

@@m809er that's what I was thinking, I wasn't plan on going with intercooler, but few have told me it would be a wise choice, I think I'll get parts on and see where stand, maybe put one on.

does it have jake brake

Sure does; all 3 jake heads are on there
