1980 Crown School Bus - Detroit Diesel 6L71 two stroke diesel

[@charlesmarcus7864]

Thank you for sitting in the back. You capture all of that Detroit Diesel sound. I had the privilege of riding one of these as a 90s kid. I would try to beat the other kids to that backseat position so I could capture the engine sound.

[@AWDfreak]

Damn, hearing that 2-stroke diesel and the proper shifts of a stick shift bring me back to elementary school... thanks so much for uploading!

[@EdMiF]

This brings back memories. Loved hearing that raspy 2-stroke exhaust note as a kid!

[@johngligo4049]

The memories of growing up in southern California in the early 90's! I rode these Crowns frequently in Elementary school while living in Palm Springs!

[@joelpaniagua2024]

Same! I also rode in one of these during my middle and high school years! I feel nostalgic!

[@skyhawk_4526]

That audio takes me back to my elementary and middle school days! So nostalgic! Loud engine with manual shifting, no seatbelts and no safe spaces! Lol. - might explain the difference between Gen-Exers and Millennials.

[@thevacuumtubejunky9774]

Skyhawk _452 : I havnt been on a bus in about 4 decades, are school busses equipped with seat belts now?.

[@thevacuumtubejunky9774]

Skyhawk _452 : Arent the Millennial school busses really short now....🤣

[@oliverroycroft1082]

Times are a changin’

[@CentralJerseyRailfan]

Skyhawk _452 compartmentalization is still relatively safe compared to a seat belt

[@Drive571]

Sounds like childhood. Rode a bus just like this on the days too rainy to walk...

[@Osamailyas]

love this model of bus. I wish they still keep classic looks to these vehicle 😖

[@thevacuumtubejunky9774]

Osama I : I agree, unfortunately Crown closed their doors for good, such a timeless classic shape. Busses now days are really square, kinda like the snotty kids of this era...lol

[@jamartaylor6958]

Great video of my Crown. We have to do it again soon sometime.

[@whackamolechamp]

I want to own a Crown just like this. Detroit Diesel 2 Stroke is an amazing motor.When I lived in So CA and we had these school buses.

[@am7b51]

Love the engine roar... I went to beverly hills grade school in one crown super coach bus!! Now I drive a semi. Ohh great memories.

[@Nabinut]

10:37 reminded me of the fire trucks I grew up with which had that same engine transmission combo pulling out of first gear. Love, love, love this video!!!

[@thevacuumtubejunky9774]

Nabinut : I grew up in a small town that had Crown fire engines, one of them didn't have a roof on it, like the one in the 70's show "Emergency", the fire dept still has one Crown that they fully restored with new paint, Alcoa aluminum wheels and lots of chrome and it's still in service today.

[@crownking3752]

waoh awsome love that sound ive ridden a crown twinkie before same engine and 5 speed ive ridden the crown series 2 with the 4 speed automatic and a 6v92 detroit diesel love that sound

[@SanDiegoKid]

I used to hate this sound... Now I love it so much. Nothin like a screamin jimmy!

[@FoxPopvli]

growing up makes you apreciate things you once hated :D Jokes apart, I agree! It's an iconic sound!

[@jeraldford3494]

I used to ride the crown bus to school they had a logo on the mirror red rabbit green duck red rooster red rabbit to school and red rooster home 😁

[@creeperawwwman3038]

you gotta love when it goes up hills, its music to my ears 1:26

[@a.toniboysmith7360]

Great video. I felt like I was riding on it and listening to that Detroit diesel 2 stroke. Awesome.

[@TheCRTman]

Damn Jamar was tearing that Crown up! That 6-71 sounds sooooo nice.

[@danvoight9393]

The lovely look and feel from the inside. All that's missing is the exhaust smell from when the driver stomps on it.

[@thevacuumtubejunky9774]

Dan Voight : We need a smellaphone...lol

[@ericyoung1478]

@@thevacuumtubejunky9774 I hope they invent that...I'm so sick of seeing videos without being able to smell the odor(s) I would be smelling should I be there in person. lol

[@trentboulanger8245]

that thing really moves

[@dirtyaznstyle4156]

This was middle school and high school bus rides for me. School was on the side of a mountain, no jakes but engine braking was just great! Transmission did some work going up and down those hills and the drivers could float gears so smooth

[@moose354]

In the 1970's, I drove many engine and transmission configs but most were either the DD 6-71 or the Cummins NHH220. The difference: The 6-71 was two stroke and was quieter and smoother than the Cummins. It accelerated and decelerated faster than the the Cummins. The NHH220 was four stroke and maintained uphill speed better than the 6-71 but is was noisier and vibrated more. When you start the Cummins, the windows start rattling. Since the 6-71 fired on every downstroke, it had half the displacement of the Cummins, 426 CI vs 855 CI. Crown change mufflers in 1974 and the engine sound was not as loud or throaty with the new muffler design. Through 1962, the standard engine was the 243 hp Hall-Scott gasser at a massive 743 CI. This bus got only 3 mpg freshly tuned up and 2 mpg between tuneups and featured two distributors and 2 spark plugs per cylinder. kzbin.info/www/bejne/omSxgZKmpquHsKc, this video shows a 1950's Crown with the old muffler applying the jake brake in second gear. The jake brake near brings the bus to a complete stop. Crowns were not only the best school bus but they were the great buses for highway or mountain charter trips. Nothing was sweeter than coming down from Big Bear Lake (el 7000) down the grade with the jake brake on.

[@SteveCarras]

moose354 Yeah!!!! 👏

[@Tchristman100]

The first diesel truck I drove had a 6-71 and 10spd in it. I had to wear ear plugs, but loved the sound. My first truck I owned (1980 KKW 86" Aerodyne cabover) had an 8V-92TA 435hp and 13spd-which was virtually twice the power of the 6-71. Then I got a truck with a Caterpillar 3406B (which I still have turning into a motorhome) and had to relearn to shift-so different. I also have a bus with a 8V-71 that I turbo'd and air to air intercooled with Jake Brake.

[@joaogoncalves1097]

Love the sound of this engine whining.

[@CodiganKelly1983]

I always imagined a DD engine of this calibur scaring the hell out of children. They'd hear it and after that, have to pop valium just to wait for the bus. They sound so angry its AWESOME!

[@rbagel55]

take the muffler out & run a straight pipe, that will make them jump !

[@skyhawk_4526]

Millennials and Zoomers would need a safe space after that. For West Coast Gen X and some Boomers, this was the everyday trip to school and back with all the sights and sounds. Looking back at it, it's so nostalgic and therapeutic to listen to. Reminds me of fond memories of middle school.

[@asleep-cult6877]

No doing homework on that bus

[@phil1fox]

Dang that Detroit sounds good....Screaming Jimmy!!!!❤️

[@danvoight9393]

Absolutely love this particular bus; it has soul!

[@thetruthspeaker1978]

WOW...the memories this thing brings back

[@michaelrmurphy2734]

I heard that diesel sound so often on the city transit buses here. I have not heard it for a long time. I didn't realize how much I missed it! GM built and supplied engines for buses until the 1990s. Then other builders and engines came along after GM Diesel Division in London, Ontario closed. RIP "New Look" bus!

[@marzsit9833]

nice drive westbound on interstate 90 crossing lake washington between mercer island and seattle.

[@Wilson632]

That' Twinkie is singing. That sweet music. Still hooked on the Motor City

[@anandarochisha]

I had a 55 PD4104 GMC Ex WESTERN TRAILWAYS. Drove it from Northern Canada to Tijuana and back. Sweet 6-71 and the 4 speed Spicer crashbox. Armstrong steering. Good Times.

[@SoCalTransitJournalist]

Wow, just wow. Outstanding video.

[@brianfalzon6739]

That crown bus looks beautiful!

[@littleexperience2.._._._._._..]

With the insane width of the bus, the engine must of been LOUD!

[@sassegranny4700]

This was for me a very nice virtual ride. I didn't drove a crown but I surely admire tremendously all who did.

[@johntapp1650]

An older truck driver told me how to best drive a truck with a Detroit engine: Mash your fingers in the door so you'll be good and mad and want to abuse that engine. You don't drive a Detroit gently, he said.

[@robertbeacham6286]

The great thing about these school buses the engine compartment is in the back of the school buses . That makes the school buses better . The engine compartments in the front of the school buses sound.

[@john242ti]

This one is mid-engined. Rear engined Crowns usually had a 4-stroke diesel and are shaped differently.

[@cidertom5140]

What an ear dieselmic noise!!!!

[@silasmcgee3647]

Gorgeous ol beast

[@tassorc]

Love this sound

[@jonathantaft8690]

Nice engine of it!

[@Artessnow]

That had got to be the loudest school bus ever. Nothing like this on the East Coast!!!

[@john242ti]

They aren't quiet. About the same noise level as an old GM PD-3751 Silversides bus. Basically the same engine, but mounted in the middle of the bus, under the floor, instead of at the rear.

[@phil4977]

Love that sound!!

[@aliciawatson2129]

I remember driving crowns when I worked at ventura unified school district in the 1997

[@ag6371]

Detroit Diesels sound the best only with manual transmissions

[@anthonymurphy2449]

Aye, main. This bus ROCKS!!! :-D

[@aliciawatson2129]

Those were the good old days, they made a big mistake discontinuing the Crown buses, they were absolutely easy for the mechanic to repair. I miss double clutching that bad baby, they sound was definitely a force to be reckoned with.

[@paulstranc9619]

where was this 1990 crown bus headed to i dont know if this was in california or somewhere on the west coast

[@busrailfan]

West Coast in Seattle. But I believe this bus has been sold off since this recording was done.

[@busrailfan]

And BTW, it was a 1980, not 1990 as mentioned in your comment.

[@yuri_on_youtube]

That's awesome, and in my Seattle neck of the woods. Who owns this bus?

Where was this? What route and where did you start and end?

[@busrailfan]

This bus was privately owned in the Seattle area at the time of this recording.

[@john242ti]

Mainly on Mercer Island, WA. Looks to be at least part of North Mercer Way, before getting onto I-90 headed westbound.

[@john242ti]

@@busrailfan Looks to be a former California bus, too, with the rear quarter mounted stop sign. Interesting that Crown still made the early nose buses with the shorter windshields and stacked headlamp/fog lamps that late in production. All the early nose units that MISD (Mercer Island School District) had in the '70s and '80s were powered with the Cummins 743ci NHH220, whereas the automatic transmission buses with the newer front end had the 6L71. Those had more of a howl to them than this manual transmission unit does.

[@thevacuumtubejunky9774]

CROWN COACH "The Porsche of busses". I would give my left arm for that bus, that would make the best schoolie motor home. I am curious as to what the max R.P.M. that Detroit has???.

[@FoxPopvli]

its max is around 2500-3000 (even more, but you'd break it) but it normally spins around 2000-2500 :)

[@thevacuumtubejunky9774]

FOX-POP-YT : Thanks for your reply. Could have fooled me, those Detroit engines sound like their turning 10,000+ rpm's.

[@FoxPopvli]

well, not 1000 but... 2500 rpm on a 2 stroke detroit diesel count as 5000 rpm on a 4 stroke diesel... imagine pushing a 220 cummins 'til 5000rpm :D

[@thevacuumtubejunky9774]

FOX-POP-YT: lol...i hear ya, I think the Cummins would self destruct in a hurry.

[@cidertom5140]

DD 71 rated at 2100 but can be maxed up to 2500. Dd53 3000+rpms

[@marcookkeomanee6168]

If I had a [Crown (Brand)] school bus, it would have a 453T.

[@thevacuumtubejunky9774]

Marco ok Keomanee : Correct me if I am wrong, isn't the 453T a 4 cylinder?.
