Thanks!

Or a punched n stroked triple nickle i.e 555 cummins

That's because it's the same engine configuration. Crossplane diesel v8. Just way larger. 14.8L

I thought the same thing, but these sound better

You’re mostly hearing a single stack… but yes, v8 motors always “fluttter”

I miss my 6.9 I have a 7.3 idi, but nothing ever piped like the 6.9. With the back windows rolled down in my old 86 F350 4door it sounded like a machine gun going off when driving by a guardrail.

gotta love old V8 n V12 diesels a lot of muscle and noise fricken Made V16s too!

Cummins put some cam timing in those things so that they could rev higher than most of the competitors V8s. They were used in some military vehicles that needed some speed.

And if I'm correct the US also had the 555 Cummins v8 to

Triple nickel ​@@kronickiller

@@ronyoung6054 us aussies call it triple trouble. Cause then have nothing but issues

Kyle H they sound weird and the 6a have more torq

Np P sound don’t matter when it’s working lol. It actually sounds pretty badass. The CAT V8 sounds much better by the way

I like the sound of the 2 stroke Detroit's, inline 6 , V6, V8 or V12 without a muffler they sound sweet , loud tho

That's cool! Did you hear about the original KW from the 70's tv show "Movin On"? They want to put the original VT903 back in it! At 2:17 you can barely hear the 903 accelerate. kzfaq.info/get/bejne/d8Cal5OhtNvTeI17.htmlere you can see and hear the engine. kzfaq.info/get/bejne/rd6SiKlnut_Oc6M.html

cletrac 12c I know the truck in the first season had a 903. They did a lot of filming around Astoria, OR and it was cool to recognize a lot of filming locations when I was stationed there in the CG. I didn’t realize they took it out of the truck, but it’s cool they want to put a 903 back in!

Here’s one of my videos with my 903: kzfaq.info/get/bejne/mbWkiNiEy9W5gWg.html

Your right! they did film up there. They had two or three of those trucks, one had the VT903 and another had an inline Cummins not sure on the model.

What was your experience with the marine 903s???

The 3408TA was turbo'd in most automotive style applications ( single turbo ), with manifolds and connector pipes to the turbo like a Ford 7.3 Powerstroke. Look up "16V149 V8 Cat" and you can see a cabover Kenworth with a 3408 running with engine shots

Thank you, Jack!

Thanks! yea she turns allot of heads when she roars by.

@@RomeKG471 No problem! I've been a fan of the older Freightliner trucks for a bit (But I'm mostly into Peterbilt 379/389 rigs and Western Star 4900 and 5700 rigs.) Not really into Freightliner but as said before the older FT trucks are what I'm a fan of (I will say that Freightliner makes a savagely radical Coronado, but their Cascadia trucks SUCK!)

Yeah, it sounds great! It brings back memories of the 903 powered trucks i drove years ago.

Detroit sounds better.

I hated air starters! When they started their trucks in a truck stop beside you it would raise you right off the bunk! Electric starter whirled the motor 500 rpm, air starter 1400 rpm.

Thanks!

Yep! still running good.

ran a 903 in a'72 astro. love the sound of the v8 . spun the front of the crankshaft off at the front of the motor coming up 77out of west Virginia.

David Woods how'd it pull ? I live in rainelle wv up in the mountains.

KELLAM POWERBUILDING How much you selling them for? Looking to repower my 03 Classic XL and do they have Jake's on any of them?

I wish too! and $2 diesel fuel prices!! lol

They do. Scania and volvo here in Aus have the options of v8. But unless you delete all EPA systems you can't hear it. And they don't sound anywhere near as good as the old pre EPA v8

yer welcome!

Fine piece of machinery brother. Your Dad was a proper old School trucker. Hats of to the man.

Thats great! Cant wait to see it! Thanks, Gary

Thanks Lisa! :)

Thanks!

Ya it was a piece a cake! I'll have to film when I have her loaded closer to 80k

cletrac 12c what's the rear wheel horsepower ? I live in rainelle wv, how's it pull in the mountain's ? sounds nice tho.

no

robert jackson or does a scan is v8 sound like a Cummins v8

The early ones were terrible.

That’s what my dad called them!

Thanks!

Ya 15 with five deep reduction, switch on the dash. I guess more like ten with five low. This engine is rated at 320hp but had it turned up a little.

Theres a video from a tv series called Movin' On-season 02 "Roadblock" that shows a 903 at around the 9:00 time line on the video. Pretty cool!

They were ok on the level but not for hill country, they are a shorter stroke and high rpm engine. I don't like to rev mine to the max, there rated 320hp at 3000 rpm, I only run mine up to 21-2200. The military versions are high rpm and are meant for short power runs, I think they put out around 500+ hp, you couldn't run that constant on hyway for long. But ya they do sound good, everyone in my area knows when I'm coming down the road, lol. Massey Ferguson used allot of them in there 4wd ag tractors too.

cletrac 12c Thanks for the reply. In Australia they seem to be most common in short bonnet fords and Kenworth’s. In the latest Cummins magazine I seen at my Dads, it says they are approaching 50 years of being manufactured. And I think in its latest incarnation it has low pressure common rail fuel injection and is rated at 650hp.

The 903 even made it into some city buses, like the Flxible "New Look" series and, in the late 1970s and early 1980s, the Grumman Flxible 870 (Flxible Metro after 1983) series and the Flyer D900 series!

A lot of it has to do with the cam timing. The 903, despite its size is a high revving engine with torque and horsepower higher in the range compared to a traditional straight 6 diesel. If the cam timing, fuel pump calibration and turbo were configured to bring the power in a little sooner, the driving experience would be much different. I believe it would rank right up there with the Mack, Cat and Scania V8s.

Yes, the 903 was an oversquare design with a 5-1/2" cylinder bore (same as the N series 6s) and 4-3/4" piston stroke.

I like all of them.

Non taken, I just like a 8 Cylinder diesels in general.

@The94GTC no

Fun fact they also appear in duplex division fire trucks on ferrara bodies

Brockway761 "BorinquenSpecial"🇵🇷

Was also offered on the GMC 9500 & Astro 95 for a short time.

Sounds like a Dodge Hemi to me.

Thanks! ya this one did too but we rebuilt heads and replaced injectors several years back. Runs allot better now.

+cletrac 12c non turbo ?

Its got a turbo, ST50

Check your oil for fuel. Injector cups and o-rings will go bad but the engine will just keep rolling.

cletrac 12c Keep the videos coming! We need to see and hear more of this old truck

No Cummins v8 sound

Trust me, the 903's sounds different from the Scania/Mack V8's.

Nissan Titan has a Cummins V8

V6 and V8

Dodge pickup still uses a junky Cummins

@@Carla-tz7qwjunky? The b series cummins is a legendary motor. If it was so junky I don’t think it would be in production after 34+ years. Of course there has been changes over the years but it’s still the best diesel engine on the market for a pickup truck and medium duty truck todayimo

@@md_randoms2429 Detroit Diesel has passed cummins up years ago. Just because Bill Clinton tried to shut them down doesn't mean they aren't out there.

I put less than 7000 miles on a year and dont run that far. It does great for what I do, now if it was working in the mountains and pulling hard all day then a newer engine would be more dependable.

I have had one just recently blow up on me. The engine block corroded had about 1.3 million Miles on it

@@willcusack1648 Pretty good milage out of it!

I just checked with Pittsburgh power about rebuilding my 903 and they said that cummins no longer has anything parts wise in stock. I found a VTA-903 and was going to use it but same parts availability issues. Unfortunately I will have to rely on aftermarket kits and old shops for parts but I'm in the same situation, low usage so it's not too big of a issue and being there aren't many running around anymore I think it's worth the effort.

When it comes to serviceability your almost out of luck, most people I know that can repair them or for that matter owned them new are pushing 70-80 years old. I know of 2 shops that can work on them but they tend to favor newer trucks because of faster parts turnaround but will work on the old stuff when things are slow.

Its on a magnet i rigged up.

Has a Cummins ST50 turbo

@@RomeKG471 nice, almost can't hear it. Do you know the hp on this rig?

@@kaulincurtis9665 only 320 been its been turned up some.

@@RomeKG471 I guess stock the turbo mostly just helps clean up the exhaust. NA is 295 I believe.

yes it came with it.

Oh Gosh ya! everythings at a standstill! Well its supposed to 50 deg. here Monday !! crazy!! This weather is so messed up! Hope yer doing well! glad to here from ya!!!

Fuller RT915

Everyone over here is all gung ho about six cylinders and emission crap. They brag about getting 700-1000 hp from them but they dont hold up for long. I love the tuff sound of V8's. Cummins still makes a V903 700+hp for the Bradley tanks. They had a truck race up in Michigan last year, unreal how they torque those trucks! They are KZfaq also.

6 cylinders are naturally balanced. V8 are not

Chance Barker you never heard a good sounding 6 cylinder???? You definitely don’t know anything about caterpillar or cummins

@@dmc016 heard most and owned a few, none sound good to me.

Chance Barker well, if that’s your opinion I respect it man

Turboed, Cummins ST-50

Ya but I never had an electronic shut down, wait for a regen or warning buzzers going off everytime the engine doesnt feel good. This old cummins just keeps going.

Yeah

@@RomeKG471 : The Best sound I ever heard!

@@Android_Warrior Thanks, this ones loud enough as is, lol

2800 rpm but some military engines and maybe ag engines were up to 3000, I generally run mine up to 2000-2200 rpm.

I had a 1971 diamond reo,903 no turbo,would turn 2750.

@@RomeKG471 Yes 2200 if time is important. No point in flogging it or the fuel bill will sink you with that capacity I was led to believe.. Plenty of pony.

The one I had in a W900 KW turned 2,700 RPM. The turbo didn't really make any noise until 2,000 RPM's

So is your fugly girlfriend!

Go away then, you dont appreciate, no need to berate.
