How many Newtonmeter got the 1986 m1009?

m1009SouthHessen · Dec 18, 2018

Hey there,

i didnt find informations @ steelsoldiers so i would start this thread!

I´ve got the information that the ´86 got 165HP and 330lb-ft @ 2100rpm.
is that right?
i think 450nm isn´t so much!

greets from germany

Taken from the TM 9-2320-289-10 The CUCV M1009 has a 6.2 L diesel at 135 bhp 3600 rpm. Not sure where the extra 30 HP are coming from that you have listed. Happy Holidays.

--- 135 horsepower = 100669.489389 newton meter/second

Look on the side of the engine air cleaner where the emissions label clearly states (for 86/87 years anyway) 155hp.

thanks guys

The GM Diesel Engine manual lists the HP as 130, the TM lists it as 135 for the J code CUCV. Where is the spec that states it is 155hp? Could that be for a civilian turbo charged motor? I would love to have 155 under my hood.

Unless I am blind I read that entire label you have posted. I never seen the HP listed. Honestly I went by the TM. It lists the engine as 135 HP at 3600 RPM. I know it isn't much but it is about the same as a 305 gas engine in the same time period. I think it is hard to really tell who is right and who is wrong. Wikipedia has this listed. I know they are not governed at 55 MPH. I drove them faster then 70 many times. Sometimes faster. [h=4]Powertrain[edit][/h]All CUCV Is were powered by GM’s 6.2L J-series Detroit Diesel V8 engine non-emissions diesel.[SUP][7][/SUP] These were rated at 155 hp (116 kW) and 240 lb⋅ft (325 N⋅m), which was 5 hp (3.7 kW) more than the emissions diesel engine of the time. They were all equipped with the TH-400 automatic. All but the M1028A1 and M1031 used the NP-208 chain drive transfer case. The M1028A1 and M1031 units had a slip-yoke rear output version of the NP-205, which was specified mainly for its PTO capacity. The CUCV series had a governed top speed of 55 mph (89 km/h).

Also listed at 135 HP.
This is a friendly debate and I am as misinformed as all involved. I tend to believe the 135HP rating.

The 305 gas was the standard engine and what the 6.2 diesel compared to in power.

305 cu in (5.0 L) (1976-2002)

130–250 hp (97–186 kW)

Merry Christmas. Friendly debate and information that others have at their finger tips.

Power output varies greatly depending on the measurement conditions. Cold, dry air at sea level is optimum, hot, humid and high elevation are worst.

The military used hot, humid and high for output of military standard engines. If I recall, 10k feet above sea level and 110 F was the standard. Could they have tested the CUCV at hot, humid and high? Elevation alone is 3% loss per 1000 feet so that would be 30% loss at 10k. I wouldn't want to drive my 1031 at 10k feet passes.

This air filter housing is off a 1986 CUCV.
My busted original housing from 1987 had identical decal.

48 cubic millimeters per stroke at 3600 RPM and a brake specific fuel consumption of 0.465 pounds per horsepower hour is worth about 160 HP. Depending on fuel density etc.

Still don't know if the BSFC numbers are net or gross. Do know keeping engine speed below 2400 RPM makes the BSFC in the 0.420 range.

The TM's and the actual GM engine manual all list the 6.2L J code HP as 135. The decal you have on your air cleaner housing is interesting. I am wondering, since it looks like a replacement decal, if it isn't one from a turbo'd 6.2 of the same vintage or someone made a mistake (a typo if you will). I searched (as much as my feeble skills allowed) and could not find a reference to 155 hp anywhere.

Your looking at out of date printed once TM's and GM manuals... 6.2 came in a ton of different options... funny enough NONE were turbo.

EVERY engine ever pretty much... came out at 1 HP number and got bumped up once or multiple times until EOL...

Tinstar · Dec 21, 2018

Decal is original.
Clean air filter housings do exist.
All 1986 and 1987 manufactured CUCVs have this very decal.
Straight from factory.

My 1987 filter housing cracked and I replaced it with one from a 1986 made CUCV.

Tinstar · Dec 21, 2018

TMs and manuals are constantly updated once published as mentioned above.
No updates inserted/installed and you will be reading out of date information.

I think this HP horse has been beaten enough.
