Yeah BUT .. when you stand her up on a 8% grade and she’s pulling 30 mph fully loaded everybody you pass getting to the top of the hill ain’t laughing in the parking neither. The 6-71 with the turbo on it put out 275-435hp depending on the injectors.
Hand down the greatest school bus ever built. Especially the 3 axle. It held 93 kids, had a midship engine, and a trunk!!! Yes a TRUNK!! What was the engine compartment on the rear engine gillig bus was rear storage on the crown. You could put a couple pallets of FREIGHT in that thing it was so big. lol
For the record--I was driving in this video. It now belongs to Tom Rice, and is a real peach! '85 Crown Turbo-Detroit 10 speed RT910. It is running a straight pipe, no muffler, which adds a bit to the exhaust note. It also necessitates a bit more care in shifting, as there is no back pressure on the exhaust side to bring engine RPMs down while shifting (I don't believe in using the Jacobs Engine Brake unnecessarily to accomplish this). The particular bus also has 24.5 TALL wheels and tires, which also changes the engine to road speed perception. After the right turn, I was upshifting on a 1.5 to 2 percent upgrade. Now you know!
Are you going to add dual 6 inch stacks? Stax don't add much. Dual straight pipes the length of the bus will do. If yours is a 4 valve, the big job is done, having the split manifold. Straight pipes add to the stack effect. Instead of 6 in try two two and a half inch pipes. They create a loud rapping sound with 4 and 6 71 2 stroke GM's (or Detroit if you prefer). I remember in the 1950's the GMC trucks, even with mufflers would produce a loud rapping sound around 1900 rpm, especially with the pedal to the metal. I had a 1953 GMC 4 banger that could wake up the dead. One more thing - having the pancake engine hanging under the bus, the engine noise is amplified by the floor and frame to which it is attached. Enjoy your big crown. we drove one back from San Francisco to Minneapolis last year. Took a month to get our hearing back.
Phil Epstein --the engine in this Crown is a Turbo 6-71 inline Detroit. The engines which really were loud were the 53 series engines, 3, 4 and 6/V6 configurations. Those were the basis that the tag “Screaming Jimmy” came from. This engine, in non-turbo form, was used in everything from ships to buses and trucks in the ‘40s. Greyhound used it exclusively in its Diesel buses up through the PD4104 and for a brief time in the PD4501 (with two of them in that bus). The PD 4501 series were repowered/converted from the 4-71 (times TWO) Detroits to the 8V71 Detroits, and GM Coach then powered the subsequent PD 4106/4107/4903 and 4905 series buses with the 8V71 series engine. There were some 12V71 engines in the MCI6 series Greyhound coaches, and even TWO MC7 series coaches that ran a very large gas turbine engine. So GENERAL MOTORS/Detroit Diesel Allison Division made a myriad of engines for many different applications in buses, trucks, ships and boats... you name it.
Just in case you need to know: jake brake + shifting only is for ujpshifting, same reason you'd double clutch (downshifting requires the opposite: pre-shift light foot-tap on accelator, then same douible-clutch). That applies is it HAS a jake.
Terry Melvin -Yeah, this one sounds like a 53 series, but is actually a 6-71 turbo engine with a straight pipe-no muffler. I am revving it only to 2000 to shift and am not using the clutch. The Eaton-Fuller RT910 RoadRanger has only a 400 rpm split between gears, so operating range during shifting will be between 1600 and 2000 rpm-You have to keep her wound up tight and in the torque range. Without the muffler, this enhances the noise factor, and makes her sound like a 53 series rather than a 71 series engine. As with most Jimmys, the old adage applies-Drive it like you stole it!!😆😆
just a typical old school detroit 2 stroke! Back in the 1980's and early/mid 1990's Winn Dixie used to have over 50 of them in GMC Brigadier trucks for delivering food from their warehouses to the stores. Those trucks were ordered so cheap that they had only one rear drive axle, no radio or A/C, and had a "drag axle" so it could still pack a full 80,000 total GCVW.
That is awesome. We had one at our high school; Bus 12, that sounded exactly like that; and loud. We had several detroits but only one that sounded like that.
th-cam.com/video/OW70qFUKTpM/w-d-xo.html Here is a sound clip from a recording from a cassette that I did over 30 years ago. The bus was down the hill from my house and 2 blocks away. The Crown in the photo is not the one making the sound , just a ramdom Crown to hit the point home. Bus 12!
It moves a bit slower on takeoff, as it takes two shifts to attain the speed that it normally takes one shift to do (10 speed transmission versus a 5 speed).
@@bryantyoung7197 I liked the newer Crown buses with the bigger windshield and lower dashboard. Gave a nice panoramic view for the driver and the kids sitting near the front.
Depending on your age, likely true - "Pleasantville" had quite a few of them in their "modern" scenes - if I am not mistaken, from the LAUSD (they were still in service there at the time). (That movie, in fact, if why I want one - I have the DVD. (I would repaint it in "replica" service scheme, add a CD drive, and be cranking Etta James' "At Last" on the CD drive (which the protagonist had playing when he took his girl to Lovers' Lane; therefore, think about that playing in a Crown).
when i was younger these were already not seen as much but they were still being used i used to always pray i got in a newer bus didnt have to ride in of these
For some reason I imagined a fictional school bus model that sounds exactly like this but the reason for said fictional bus sounding that way is because the driver was shifting in the higher gears and part of it also had to do with the bus having a turbocharged engine out of a Nissan Skyline albeit connected to the driveshaft via low gearing (more like reverse overdrive as a way to increase torque) as opposed to being 2 stroke as in the Crown. Also both buses obviously have manual transmissions. I’m not saying the crown has an overdrive though, just sounds like it because it’s 2 stroke.
In California the people that drive a Prius are either doing it to commute but then you also have the far left liberal Prius drivers that buy them because they think they're actually saving the earth.
There were buses like that of route in my country, i live in el salvadore, the nicknames of thoses buses are Papayas and the Cantalopes for the form of the bus, and one question, those those buses still working in the USA, i gone to the usa 3 times of my life, and i traveled in bart trains to.

In El Salvador are not working anymore but I thing in the USA yes they still working.
Exhaust Note is Great! Only Problem is, It looks Like It’s Taking So much effort to Go so Little speed. And the gear chances are Terrible. Other than that, it’s Great!
But there were turbocharged versions of Detroit Diesels, such as the 6V92TA which was used in the Crown Supercoach II, the successor to this school bus, but there was even a turbocharged version of this exact engine called the 6-71T. Another thing to note is that twincharging exists, the supercharger feeds the engine the air at lower revs, then at a certain rate the turbochargers kick in and do their job at higher rpm’s.
@@dth2brny121 Good point! Also used in the Carpenter Crown RE in the early 90’s as well as the Chickasha/New Bus company NBR type D RE (almost none exist). But that time I referred to the Supercoach II because the Supercoach 1st gen was mentioned.

Lol.. yep that makes so much sense.
litterally every excuse when I was in high school
screaming jimmy baby😩😤 music to my ears
i don't remember them being this slow 😂 sounds amazing either way
I love these old Detroits but I can't believe the I am just now realizing 6 series sounds like the New Supra 😂.
It did seem to go a bit slow. But that’s just how a typical crown dose for its age.
It moves a bit slower on takeoff, as it takes two shifts to attain the speed that it normally takes one shift to do (10 speed transmission versus a 5 speed).
0-60 in two weeks. lol
The crown buses don't even want to move
It's just those slow as a snail detroit two strokes! When Detroit came out with the 4 stroke "series 60" engines, they found some speed.
This crown bus had manual shifting, of course it would accelerate slow
You could hear that bus coming miles away
Imagine the diesel smell from that monster!
Those Detroit crowns sound just like a Supra! Wish I could have heard that gillig at the end too

Because they had the same engine. Nearly all diesel buses back then used the two stroke detroit because they got superior fuel mileage for the time.
