8v92 Peterbilt

[@MasterWitchDoctor]

My 1st Pete was a '75 359 with an OO92 I ordered new to haul milk in Florida for Milk Express. It was a twin stick Spicer 4x4 with 3.70 gears with a single bunk 36 inch sleeper. Joe Vitavicchi got me the job and my dad got me the loan for the truck. I doubled up my payments and had it paid off in 30 months. What I didn't know was the finance company (Farm Credit) loaned me my dads money and put my payments into escrow and they gave it back to him in a lump sum. Once the Detroit needed a major overhaul I replaced it with a 400 Cummins which had about the same torque and a whole lot less noise and better fuel economy. I had that truck for 20 years and I wish I never sold it, she was a good one for sure.

[@sidefx996]

Wow that sounds incredible. Don't think I could ever get tired of listening to that.

[@ihfan29]

The 8v92 was reengineered to be better on fuel if I remember correct. I know the 8v92 in the M1070 Oshkosh is 500hp.

[@danielkavanaugh2124]

Old truck sound good. I remember many cold mornings. But sittin the cab of a Pete. Bring back alot of menories 44 yrs worth Thanks for posting it DK

[@mylittleponydude9612]

this truck just screams, "MORNING NEIGHBORS!!!!"

[@mylittleponydude9612]

***** well, you might get tired of it every now and again

[@mikelamothesr.8998]

Until you have driven one, day in, day out, you would never know just how accurate your post is.

[@SlavJerry]

And jake brake for "HOW ARE YOU!?"

[@mylittleponydude9612]

man i love that hot rod sound of the 8v92

[@MasterWitchDoctor]

mine I upgraded to the 9E95 injectors which rated my OO92 at 480 hp.

[@ramilzeyd4986]

Звук отличный. Помню свою молодость. Отъездил на Кенворт С500 с двигателем DD 8-92 целых 8 лет. Отличный двигатель. Без проблем. Но весь в масле. Потом поменяли на DD 60. Но это уже другая история

[@PreciousAlpschindler]

Wow I didn't expect a 2 stroke to sound like this it awesome! They didn't even sound close to a 2 stroke bike or a Subaru 360! This is awesome!!! Turbo sound in this thing is awesome

[@BenjaminEsposti]

That's because it's a diesel and it's 8 cylinders. Sounds much different than a 2 cyl 2 stroke gas bike engine. :P

[@mackdetroit4life]

This is the best sounding 8V92/jake brake video yet!!...Keep 'em comin!!

[@briank06261973]

Sounds nice. My dad drove a '79 Pete 359 with a Silver 92 in it some years ago. Always liked the sound of an old school Detroit. Real heavy metal, and that's coming from a metalhead..

[@ericcartman8716]

Sounds like shit

[@codykennedy19]

Absolutely amazing sounding truck and I just now subscribed to your channel. Will you please see if we can do a three or four hour ASMR video of this thing but with a really really high rpm up shifting and include engine start up I love that plus the jet break is just icing on top of the cake. Stay safe man have a great one. I hope all is well with you.

[@cobaltlukather9045]

@balla according to Depco standard engine specifications, a detroit diesel 12v71 makes 475 horsepower in naturally aspirated form, and 550 horsepower in turbocharged form. an 8v92, however, makes only 370 horsepower naturally aspirated, and 430 horsepower turbocharged. the 8v92, however, is over 700 pounds lighter than the 12v71. i wouldn't trust the power ratings much though, as you can find many 500hp 8v92s, and some 700+hp 8v92s, primarily in marine applications. the 92 series was a replacement for the 71 series, so you can likely see many gains in the economy and reliability of a 92 from a 71. however, i'm just a kid who researches old diesels. i have no real hands-on knowledge of these things.

[@iBackshift]

+Cobalt “Robert” Lukather Stout for a little 12 liter engine. 8V92TA 450 hp 9G90 injector @ 1165 lb/tq @ 1650 rpm 8V92TA 500 hp 9G00 injector @ 1325 lb/tq @ 1700 rpm 1987 Silver 8V92TA stock 475 hp w/9G90S @ 1330 lb.ft. at 1300 RPM - in them years the Silver 892 was the Grizzly. Today there is the Lion - Latest Scania V-8 (16 liter) 730hp (1990 lb/tq) @ 1900 rpms and 2685 lb/tq @ 1300 rpm. (487hp @ 1000 rpms)...unreal ! I hope someday you get to drive a truck with an 8v92 in it - its a joy.

[@cobaltlukather9045]

i take it you've had a detroit or two in the past? i'd like to hear more about them

[@iBackshift]

+Cobalt “Robert” Lukather - 1989 @ 18, my first learning experiences for driving a diesel dumptruck - 72 Autocar setback w/318(8v71), then 19yrs old on a 78 Transtar 4300 w/a red 435 8v92. 1996, drove two 84 GMC generals (silver 6v92, 350hp, silver 8v92, 430hp) 1993~2000, 72 Ford 9000 w/silver 6v92, 350hp & a 86 Freightliner FLD setback w/a Silver 892 475hp. 1981 KW w90a w/a 445 8v92. Never owned them, just drove them for two of my best friends.

[@cobaltlukather9045]

sounds very cool. what were they like long distance? what were they like when you were just cruising easy and when you were pushing them hard?

[@iBackshift]

+Cobalt “Robert” Lukather - Only the 72 ford w/3 axle dump trailer (gvw 107,000) and 86 FLD 5 axle dump trailer (gvw 139,500) were long distance (20 hour round trip) I hauled aggregate. The rest were all local tri axle dumptrucks (tandem w/air lifts) The 350 was slow in the hills, 15 spd and down in 3rd just to try to hold 1800. The 475 did alright, 18 spd 4th high - look up "cavers hill nipigon" With the 475 it would take about 7~8 minutes on the rug @ 1800 to climb 660' to 1100' elevation before shifting 1/2 a gear. The weird thing is out on a flat passing lane, (475 x 892) I could pull out and pass a log hauling truck with similar weight running a 450 DDEC w/18 spd. In that hill my buddy Billy would go by me a gear higher. Dint matter if I ran that 475 at 1800 or 2350 in the hill, still pulled about the same, just different gear. Out on the flat is where the engine speed took over it seemed. I would flip the cruise control in that hill, then get out my windex bottle and clean the windows and the dash, mebbe have a sandwich and a coffee. Its just straight up with a curve at the top i could steer with my knee.

[@nfarnell1]

standard 12v71 in a tractor was 467 hp @ 2100, 8v92t was 375 @ 2100. both engines could be set up for huge hp. a firetruck spec for 8v92tt is 634 hp @ 2100 12v71ntt is rated @ 710 hp @ 2100.

[@idreamofdragonso5677]

Wow a video where I can hear turbo whistle from a old 2 stroke Detroit, what is this?

[@holysirsalad]

Funny you mention that. I grew up riding Detroit-powered buses everywhere, I have fond memories of falling asleep in the back over the engine on a cold winter's night. I was always confused why nothing else sounded the same (ubiquitous DT466, Cummins trucks etc) There is no substitute for a two-stroke!

[@lsswappedcessna]

This truck seems to be giving off good vibrations.

[@Darth-Nihilus1]

8v92ta is a mean motor, my fire departments pumper has 1 and second 1 has the 6v92ta. They scream and the Jake barks so loud. I straight piped the 6v92ta but I haven't gotten around to straight pipe the 8v92ta

[@sipos66]

Way to go gear jammer! was a fun ride in Idaho, givin' it hell & stabbin' them gears, grindin' em till they fit! yee-haw! Was almost like ridin' with the Snowman! Thanx!

[@mackdetroit4life]

You may have some dificulty with that modification of a 8V92 in an R600 chassis because of the radiator clearance,front mount,and air intake problems...but also frame/exhaust manifold clearance...but it can be done. i remember seeing an 8V71 installed in a R600 glider kit from 1976...and it went like hell...but extremely hot in summertime conditions...Good luck!

[@82MB240D]

You've got a nice sounding truck. Great camera angle too

[@DGruhot92]

Sounds great! Love the transmission whine

[@BenjaminEsposti]

LOL the horses on the left at 2:12 didn't even look up to see what the hell the noise was. They must be used to that noise. XD

[@truccboi214]

ecksdee

[@James-kd7dc]

​@@truccboi214purple tomato sunset oranges ,!! Read more..

[@shedlock2000]

The blower on this is way noisier than on others iv heard! Did you do something to the pulley?

[@flewnvy]

Awesome sound from this old girl. Not sure which is better, the 92 or the whine of the transmission... It's all good.

[@unclewilly2]

Do the 8V92T have more Power or Torque ? And how much HP and Torque dies the 12V71TT have ? :-P I Love the sound of an old screemin Detroid !

[@jimbos1175]

At fire department I'm at our pumper has a 500 horse single turbo 8v92ta with an automatic transmission and it halls ass. I love the power and reliability of of the engine. The Jake screams and the turbo sounds amazing. 500 horse is plenty off a single turbo, twin turbo would have 550 to 1000 horse. I went to school for diesel for five years and I loved working on 71 series and 53 series Detroits how ever the 92 s are amazing and reliable. I do fancy myself a 60/12.7 or 60/14 liter but you can't go wrong with a new OM71 DD13. Cat C15 compound turbo 550/600 is a good engine as well but you can't get them anymore unless it is used same as the 60

[@jimmyhill9843]

yes I love the 92 series just don't overheat it one time or liner seals are cooked and youre mixing water with oil lol

[@mobilek5267]

AWESOME SOUND!

[@wazza33racer]

truly beautiful sound............mankind is just superb with technology

[@MolecularShadowFox]

Just music to the ears :3 Love it

[@unclewilly2]

Yes, i know, but it has actualli 92 c.i. per Cylinder.. so its a littel bit more Does they have more Bore or more Stroke ? Do you know what Torque a 12V71 produces ?

[@vincej8436]

That is just awesome. I wish I could hear my 60 series egr. But soon will try 8 inch strait pipes see how mine sounds then.

[@trucking604]

Used to drive a Pete with a 3408 Cat. 475hp I believe.

[@aaroncone6778]

Sounds pretty healthy! Nice Video!

[@9890jake]

Very cool! Makes me want to get my old 8v92 out and run her.

[@flyingscrapyard]

Very rewarding. Definitely agree with flewnvy. Hope there are some follow ups. Anything else sound wrong. I was was waiting for the frost on the bonnet to disappear after a bit of running - it must be fairly cold there. Where is there anyway?

[@scottmurray9391]

the 12v71 came stock a 500 the 8v92 is only a 475 horse where the 1271 is at it's bottom setting at 500

[@idreamofdragonso5677]

No 8v92 came in many ratings my dad drove a gmc general with an 8v92 that had twin turbos I think 515 horse power

[@GMC6523]

what year is that peterbuilt early 80s late 70s

[@austinbrad91]

You just got to love them jake brakes on them old Peterbilt's.

[@8v71buses]

Trust me you aren't the only one that thinks that! IMO the Series 60 sounds closest to the Cummins M11. BTW I still remember when Cobb Community Transit's 1994 Flxible Metros were M11 powered and I swore they were Series 60 engines because of their sound

[@getbent876]

Man those blowers sure sound good.

[@unclewilly2]

Does the 8V92T produce more Power then the 12V71 ? Was there some 12V71T's out there ?

[@MasterWitchDoctor]

no

[@unclewilly2]

What is more Powerfull for all day use ? a 8V92 or a 12V71 ? I thought because the 8V has more Displacement ! :)

[@MasterWitchDoctor]

12V71 with a #70 injectors was 475 hp @ 2100 but the torgue was more like 1500. My Pete came with a OO92 that was rated at 430 hp which I replaced the injectors in and put 9E95s and added and aftercooler which bumped up the hp to 480 and torque from 1160 @ 1400 to 1330 @1300. It didn't cost any noticeable increase in fuel but it picked up about 10 mph. She could run triple digits with not problem at all.

[@DLCFarms]

I've always wondered, is it true the rumors about all the detroit diesels that they have bad oil leaks? burn oil aswell?

[@DOffio]

If you keep (or kept) the maintenance up on the ol sweethearts, they don't burn oil. They will always leak a little bit, but, hell, my '13 Pete with an ISX in it leaks a little. But with the old DD's, you had to run straight 40 in them, 15W40 would just pour out, and there are a few seals that are high wear items, if you don't keep them changed, she leaks alot more. Also, you learned fairly quick to run them on the Add line on the dipstick. Every one I ran would throw the top gallon of oil off really quick, but it would sit on the add line for a long time. Of course, every 60 series I ran did the same thing, so, maybe it is just a Detroit thing! lol

[@johnhull6363]

Brock D if you idle them extended time they leak out the air box drains (it's a two stroke thing) some had tubes back to sump Instead of ground

[@benmurray8689]

Mechanic told me that you need to know how to assemble a Detroit properly. Need to get the correct amount of sealant in the right place, if you don't get it right it will have assembled a leaker.

[@benmurray8689]

I drove a truck with a 14L series 60 for 250 thousand km. Other than the services it did not need to be topped up with oil

[@charles8010]

What's years on your Peterbilt ?

[@bj99ful]

I always enjoyed the sound of the 2 stroke Detroits also; I grew up with them. Starting with the 60 Series, Detroits didn't sound much different from a Cummins; they definitely lost the distinctive sound that made them really stand out

[@benmurray8689]

bj99ful series 60 has its own distinct sound.

[@66kenworthowner]

Sounds like an 8V71 ?

[@DanielBoonesloggingvideos]

pure awesomeness !!!

[@trucking604]

400hp??

[@NitroTheDingo]

Now I know where the sound source came from in ats.

[@txstreetman]

What transmission is in it?

[@alvie2]

+txstreetman the kind that needs rebuilt.. see 2:07

[@ThatMNTrucker93]

+alvie2 You don't need a rebuilt transmission just because of a scratched gear. Non synchro 13 speed. Match rpms manually

[@Wildstar40]

I got sea sick from the shaky camera, Detroit Diesel, Turbo, Transmission whine, Jake Brake, Driven Respectfully ... Totally worth throwing up a little bit from that damn camera !

[@justintownsend8856]

I thought you were going to take out an elk mr. Undertaker

[@James-kd7dc]

They may be hated by some, but even those will admit theres never been a better sounding engine.

[@novuutheneolf]

Pretty, pretty sounding. I got just one question: Why do you like these big cruisers, but you boycott Volkswagens?! :DDDDD

[@farmboy26ful]

there are 12v71 and 12v71TT aswell! they sound so cool!

[@MasterWitchDoctor]

the marine 12V71TA was rated @ 650 hp @ 2100 with a 9290 injectors. With 9E95s or M95 marine injectors they were rated @ 710 @ 2100.

[@Steve.Vaught]

In today's day and age of junk on wheels you have it goooooooooood!

[@calvincrews3885]

it's a two stroke Detroit diesel 8V92 736 cubic inch displacement just like in the 1997 sutphen areial tower 95 ft quint the 8V71 N is a 580 cu in motor one or two stroke Detroit diesel engines 76 stuphen areial tower 100 ft witch it was equipped with the 8V71 N two stroke Detroit diesel engine

[@calvincrews3885]

By that I mean Sutphen

[@James-kd7dc]

One or two stroke? Explain that to me if you can...

[@ChrisFerLOL]

This is gold

[@shanelord5012]

Awesome

[@bryanlaurenson3866]

Its a 1977.

[@Detroit8V92tta]

Yeah me too.

[@userfriendly1981]

The guy's soft on the engine but not with the Transmission.... Don't forget your fuel shot before downshifting dude ;)

[@66kenworthowner]

Sorry 8v92

[@arthurscrote4640]

Nice truck but wouldn't want to spend ten hours a day listening to it. Great for shows but no operator would entertain noise like that in Europe. Way beyond acceptable cab noise limits.

[@woodsmen17]

You must not be american ?

[@ThePaulv12]

jarrod flowers Yeah. Not many truckers I know work only 10 hours a day. No operator huh? 1000s of us spend 18 hours a day in trucks like this.

[@woodsmen17]

ThePaulv12 I agree with you totally I could listen to this all day , dont get me wrong I could listen to a 4 stroke cummins all day to , but hey its a preference thing,can't agree on everything.

[@SoFloCamejo]

Hell lol, I could listen to anything for more than 10 hours a day. From a v-4 2 stroke outboard to a 3406 cat.

[@ChristianArreguin]

Arthur Scrote WHHHAHT! I CANT HEAR YOU OVER THE SOUND OF FFFFFREEEEDOM!
