Gotta love a 8v92. With the 5 speed they were easily the fastest of the greyhound buses I drove and could almost outclimb cars on serious highway hill grades like the Coquihalla snow shed hill. 80kph on that grade with bus L801 (former Maverick bus) with a good load of passengers. L800 was the fast though and could nearly pull 100kph on the same hill. Very unusual feeling leaning into the corners going uphill on a heavy grade..
@@jlo13800 WAT? they run on diesel ... if you wanna try alternative fuels there is propane, or biofuels like Soy oil, or biodiesel, its not gonna ever run on ethanol because ethanol has very poor detonation characteristics so basically exactly the wrong fuel for a diesel engine.
Scott you have mentioned more than once your distate for K&N filters. I don't like them either, they can really foul the electrical grid for the mass air flow sensor as that pre-oiled filter can get grease and dirt all over the wire grid in between the sensor and the air box on some cars.
Projectfarm channel did a filter comparison video that proves how much particulates the k&n let go through. They are a bad idea for any vehicle you want to last.
Some back in the day bus engine history, In the Soviet Union / Russia, various versions of this engine-type were produced at the YaAZ automobile factory in Yaroslavl.[18] Throughout World War II, the 4-71 engine both in locally assembled form (built by Lend-Lease provided American industrial equipment) and from USA-supplied kits had been used for Ya-12 light artillery tractors.[19] After 1945, the 4-71 engine entered production in a slightly modified configuration to suit the conditions of the Soviet Union branded "YaAZ-204".[18] After 1947 the factory used a copy of the 6-71 engine branded "YaAZ-206" in the heavy trucks YaAZ-210 and YaAZ-214 built from 1951 to 1959. The vehicle production was transferred to KrAZ in Kremenchuk, Ukraine in 1959, where trucks with newer versions of the YaAZ-206 stood in production until the appearance of the four-stroke V8-engined KrAZ-255 in 1967.[2
I’m surprised that it didn’t throw gravel all over you, maybe after the tune up, those silver 92s are a beast.🏎 Wow you’re property went from nothing to the snap on truck showing up.👍
Some years ago a friend in Oregon tried his car out on a dyno using a factory paper cartridge air filter and did a few pulls with a K&N set up... The latter caused a definite power loss ,mostly because it allowed hot air from under the hood to be used rather than the cooler outside air. So not really up to the job of improving horsepower out put .
The standard air intake has a cold air feed, if you don’t install one for the k&n you’ll get bad results. Otherwise k&n is a guaranteed power increase. The foam allows more air in which produces more power. Performance filters that take away power are either installed wrong or are cheap garbage
I know someone who swore by his, told me every time he washed and oiled it...until his MAF got dirty. I've never seen a dirty MAF with a regularly changed paper filter.
This one took me awhile on how the name “Prevost” was pronounced. The “S”, and “T” are silent. It’s like 👍 “Prevo” for the pronunciation. Great 👍 bus 🚌. Your friend, Jeff.
The worst thing possible to do for a power increase, is to switch to an oiled filter like a K&N. My stock filter on my 03 Ford can keep up with the turbo on the 6.0 very well. As it gets near time to blow it off, or replace it. My black smoke is very minimal, and my engine is not stock. A better flowing piping helps a lot.
I used to work for a coach builder back in the late 90's ... Prevost buses had 500HP Detroit engines... they get with the program. They are/were the "Cadillac" of buses.
That is a really nice Snap On tool box. I probably could afford a drawer.... but not the big one. You should have a start and stop point marked on your hill and record the times of the busses to make it up the hill. Before and after tune up where applicable. Today's bus would have to be one of the quicker ones.
That bus is a fast beast...and really pretty outside. Christmas in September courtesy of the Snap On delivery guy...thats one very very pretty roll box!!! Huge congrats again to you guys...all the hard work and everything with the building is paying off:-) Its gotta be great to walk out your door and work under cover:-)
K & N Filters are fine. People don't follow directions cleaning them (Using high pressure water such as hose with nozzle instead of running water over it which blows out some of the cotton in the creases). That ruins it and allows dirt through. They almost always over oil it. It takes very little oil to do it properly. I had one for over 300k miles and never had a dirty turbo or any oil problems.
Wow that thing moves like a stabbed rat! I am surprised it’s a mechanical engine, what year is the Prevost? Curious to see how it drives once the injectors are adjusted. I finally was able to test my jake dial indicator set up, it’s a bit more fiddly than the snap on gauge but works good.
Back then The Prevost was known as the Mirrage from 1976 to 2006 a year later the name was switched to X345 from the Detroit Diesel years to Volvo D13 and probably a Cummins engine as well
Scott, seeing your videos of air box wear due to poor filtration has me wondering how many 100K miles have been lost on this motor... What is your criteria for replacing the turbo? That one looks real bad, and I would be concerned about it letting go and taking out other stuff "downstream" - great videos sir!
Any filter that flows more air, flows more dirt. If you have a race engine yes go as unrestrictive as you can but on a diesel bus engine designed to easily go hundreds of thousands of miles, it'll kill your engine prematurely. On an engines like this the power difference will be undetectable.
You'll still detect it - when it blows up... but that is the correct answer. K&N are for racers and tuners who want the last 5HP (or so). All others, who want the last 50,000 miles better not use them.
Wow watching the hot rod buss I didn’t realize how big your property is. Nice Snap On box you got for the shop! I’m not a fan of K/N air filters. I’ve seen too much dirt get passed them. Seen them foul mass air flow sensors. There good for racing purposes only.
Filtration isnt rocket science. In order to flow more air you need a bigger filter. In order to flow more air thru the same space you need less filtration (resistance). K&n type filters usually are installed on what is called a cold air intake. Thats laughable, they are open to the hottest place in a vehicle, the engine compartment, using the least dense air possible, making the least power possible... Gale Banks has a very good series of videos explaning this precept.
I laugh at people looking for a "cold air intake". Umm, my Subaru has a cold air intake right from the factory - the inlet draws from right above the grille! Is it the most direct pathway? Maybe not, but it's better than the hot air under the hood!
Need to be careful with the K&Ns as they let lots of fine particulate in. I have to run them due to how small the airbox is in my car, but they do cause scuffing and polishing of the bores where the piston skirt is being loaded after a while due to all the fine silt. Anything off-road would be a definite no-no as they will quickly trash an engine in short order in dusty conditions.
Scott, good evening. Thank You for sharing this video. May I sak You this_ Lenny body is made out of aluminium? or Is it built on stainless Steel?. I saw the baggage doors open and I could watch the supports made out of a stainless material. Thank You
I’m truly surprised there hasn’t been a class action lawsuit for the engine wear caused by using k&n filter after all these years. My acura Tsx came with one. When I shone a light through it after its first cleaning I threw it away. The pores in it were big enough to actually see the beam shine through.
K&N is deceiving. Sounds and feels like more power initially but becomes problematic in short order. Might be proper for off road racing situations etc. But they don’t appear to be beneficial for street vehicle use. When I saw that Snap On ( good stuff BTW ) truck backing up to the shop I immediately thought “there goes the check book “ 😢😜🤣 Congratulations on a toolbox that will last well into your great grandchildren!!
O.O Okay then, well then I'm NOT getting a K&N filter for my Subaru Outback with a 6-speed stick behind it, after seeing the damage to that turbo. My Outback is a rare gem in my region because of it having the 6-speed stick and I bought it with 123k on it, just rolled over 142k after having the coolant replaced and a bunch of other PM at 137.5k. I'm wanting it to last me 10+ years and so now I know to STAY AWAY from a K&N filter, stay with the stock paper element filter.
Gotta love a 8v92.

What a gnarly Driving Experience wish I would have had the opportunity
I want to get my 8v92 silver turbo to work on ethanol.
@@jlo13800 WAT? they run on diesel ... if you wanna try alternative fuels there is propane, or biofuels like Soy oil, or biodiesel, its not gonna ever run on ethanol because ethanol has very poor detonation characteristics so basically exactly the wrong fuel for a diesel engine.
And when the snap on guy drops his tailgate you know your checkbook is gonna cry...
Big boys playing with big buses need big boxes i suppose... lol
After you pass the top step it's consensual.
You must got a good special on that toolbox. It looks nice. Thank you for all your videos KY.
LOVE that , 2 min in the video VROOOMM up the hill he goes , that has to be the best hill climb i have seen to date
Like a rocket. I was impressed.

I was going to put a k&n col air intake on. Went to the dealer and the old guy behind the counter said not a good thing to do.
Projectfarm channel did a filter comparison video that proves how much particulates the k&n let go through. They are a bad idea for any vehicle you want to last.
The only thing worse than a K&N is running with no filter!
Cold air intake.
More air with the same/similar size filter = more dirt passing through the filter. Goes for all of em not just K&N.

That turbine wheel was ready to start making its way thru the housing. Wow. Ken and Nancy win again.
Holy moly talk about a solid launch wow
Another wow video! Love the new box and with your new workshop only a little envious ;)

Very true!
They sell the sizzle not the steak!
Always suck cold air!
KnN stops dead chickens and large debris.. A great way to kill a very expensive engine.

Stops dead chickens 🤣🤣🤣
Nice new box. Congratulations. No doubt you’ve waited a good long while for that special delivery.
This one took me awhile on how the name “Prevost” was pronounced. The “S”, and “T” are silent. It’s like 👍 “Prevo” for the pronunciation. Great 👍 bus 🚌. Your friend, Jeff.
The P is not silent, unlike in swimming.
en francias because they are manufactured in Quebec
Down south we just pronounce it all . Pre vost
@@ServantofYaHi777 Very hilarious 😂. Your friend, Jeff.
Im in north chicago and I love the backround sounds when you have been recording the voice-overs!

While I’m not a fan of K&N filters either, a oil bath filter system is the best filtering system to use.
And at 5:00 we see BGM’s equivalent of the ice cream truck arrive. Snap-On should put bells on the trucks...
That’s a really nice tool box. I can’t imagine that it was inexpensive. Beautiful bus!
Hope they didn't bend ya over too bad on that box!!
That's not the Cadilac model so it's just a few grand!
Oooo the Snap-on guy…. Man listen, my pockets!
I used to work for a coach builder back in the late 90's ... Prevost buses had 500HP Detroit engines... they get with the program. They are/were the "Cadillac" of buses.
You might get an electric leaf blower to dry out the floor when needed.
It also works to clean the floor of your garage.
I have one. Beats vacuuming!
Love seeing the snap on truck driving around my town :) They got fancy LED lights in the front and back and the rear lift is so friggen cool
Your customer was watching the Snap-On box come off the truck and wondering.... "Did I just pay for that?" Great job as always Scott!
It Definitely HAULED AZZ Up that Hill, Bye Far the Fastest I've Seen 💯👍🏾👏🏽‼‼‼
Awesome Tool Box there Tyler, Top-Of-The-Line Snap-On💯💯💯‼‼‼
That's not my box lol i have a Macsimizer
i bet that little town is lovin all the new money comin in
736ci is a lot of motor. Witness the way it charged up that hill like a rocket.
That thing moves
Another indication that size DOES matter!
That is a really nice Snap On tool box. I probably could afford a drawer.... but not the big one. You should have a start and stop point marked on your hill and record the times of the busses to make it up the hill. Before and after tune up where applicable.

That's always a fun day when the Snap-On tool truck shows up.
Wow, that bus gets down. A beautiful conversion!
Wee doggies Ellie Mae, the money for that Snap-on box could buy somebody a fine automobile!
He went up that so fast 💨
That bus is a fast beast...and really pretty outside. Christmas in September courtesy of the Snap On delivery guy...thats one very very pretty roll box!!! Huge congrats again to you guys...all the hard work and everything with the building is paying off:-) Its gotta be great to walk out your door and work under cover:-)
Realy proud the things you have accomplished. Good job.
Well damn it did haul butt up that hill 😂
Didn’t expect that
And THAT is what an 8V92 turbo brings to the party!
8V92ta
Wow that was a fast climbing bus 😳
Great video 😊
Its got tesla motors in in and a fake noise.

That Bad Boy has the power .
He took a running start
🤣 That thing was hauling up that hill. Beautiful rig👍
Bus owners just don't get it about K&N filters and diesel engines.
Anyone with any vehicle.
Wow that thing moves like a stabbed rat! I am surprised it’s a mechanical engine, what year is the Prevost? Curious to see how it drives once the injectors are adjusted. I finally was able to test my jake dial indicator set up, it’s a bit more fiddly than the snap on gauge but works good.
That thing can fly.
No smoke.....no poke
Back then The Prevost was known as the Mirrage from 1976 to 2006 a year later the name was switched to X345 from the Detroit Diesel years to Volvo D13 and probably a Cummins engine as well
I agree on the K&N filters, think that they are junk!
That was the first time I saw a turbo impeller with a sidewalk texture on it's surface.
I do not know why anyone would use a K&N air filter for any vehicle and any engine. Gotta love those 8V92TA's, nothing like them.
sound good
Snap On Truck. Sell your other kidney. :)
Send it. That's a good one
Ooh that's nice got that Bandit look to it.
Provost is nice, but I like the older stuff ☮
My 4106 has an 8v71 turbo in it with 100 injectors. It moves pretty good
Someone needs to put a 12V92TTA in a bus.
That’s a beautiful bus!!

It like pilgrims going to Jerusalem for buses.
Hi y’all from west Alabama love ya
That has to be the record for going up the hill.. N
Holly smokes!..speedy gonazlez !
I have significant Roller Toolbox Envy at this point 🙂
Up that hill like a scalded cat!
Beautiful toolbox
You can get the same performance and filtration as a K&N from a red shop rag and a zip tie for a lot less money.
Any filter that flows more air, flows more dirt. If you have a race engine yes go as unrestrictive as you can but on a diesel bus engine designed to easily go hundreds of thousands of miles, it'll kill your engine prematurely. On an engines like this the power difference will be undetectable.

There were cracks on that airbag...looked like it from this end...

That’s only like 20% of the property.
I would have changed that turbo once you start getting nicks and gets out of balance the vibrations sometimes ends up breaking the shaft
keep the videos coming

Is the family with the Saudi bus just hanging out there? I have seen them there helping and hanging out on the last few videos of different busses.
I know where that snap on toolbox is made at.
Algona Iowa .Snap on toolbox factory is there. They make a lot of other brands there also.

How old is this bus and what kind of money do they go for? If upkeep wasn’t outrageous I’d rather live in one of these than a house! Nice bus!
"This k&n is not doing this engine any favors".
Yup.
The Snap on man
Scott, good evening.
Thank You for sharing this video.
May I sak You this_ Lenny body is made out of aluminium? or Is it built on stainless Steel?. I saw the baggage doors open and I could watch the supports made out of a stainless material.

I was wondering what was coming from the candy store...
Needs some 9A95 injectors. LMAO 😊 🤣
Wow it's fast
I hope that Snap-On box was free....
I hope they’re sending you quality airbags and brake chambers, or they’ll be back before their time.
You must love working on a clean engine for a change.

K&an filters do no work well With diesels . I have seen both powerstroke and duramax light duty Diesel engines dusted from running them.
they don't work well on anything.
I want to take my Subaru up that hill lol
That hill seems a lot like a tractor pull. Anyone ever fail to make a "full pull?"
I didn’t make it up once in my bus. But i started on the incline already. That’s like climbing a 8 story building in a few hundred feet.

Why not switch to a electronic boost gauge, I am sure there is a spare wire ready to be used or you could run your own wire
Did I miss it. What year Prevost?
1986
Hope you are charging rent for the floor space and also for parking on your land. Ya gotta pass your costs on to customers.
O.O Okay then, well then I'm NOT getting a K&N filter for my Subaru Outback with a 6-speed stick behind it, after seeing the damage to that turbo.

What model....part number is the new snap on box is it a master series or an epic series???
You must be paying a lot in KHO fines at the moment!
430 horsepower they haul the mail turbo is junk hope owner wants it replaced throw away K&N filter setup
