Mack's MP8 505C+ MaxiCruise Pt.1: Small Block, Big Load
Вставка
- Опубліковано 10 гру 2014
- Mack's 13-litre MP8 engine may be small in stature, but it's big on performance. It delivers 505 horsepower and 1,860 lb-ft of torque, which is more than enough to pull 138,000 lbs through the mountains on B.C.'s Vancouver Island.

I like what he said about the power management makes it impossible to damage a engine. Seen many drivers over rev older trucks.
More engine displacement equals better exhaust braking, something they didn't mention.
Nice interior.
Every Mack I've drove pulled good , never got out of a pull I'd put my 550 6NZ against it
I now have a few mp8s. 13 speed and 330 gears
I have a 5ek cat 475 hp 13 speed and 390 gears
Also have a 6nz 550 hp 18 speed and 355 gears
There is a hill we climb from a rolling start. Couldn't tell you the percentage. It's 3 miles long. The 5ek tops it at 55 mph. The MP8s get there at 65 mph. The 6nz gets there at 66.
But the MP8s are getting way better milage than the cats.
@@texgarcia1958 I have a new Pinnacle on the way with a 505 Mp8 and the Mdrive 12 spd I hope it'll perform well .
6 years later & he's right!
I think it is very bad when you see an article like this and at 48 seconds into it we see you throwing trash on to the Highway. Truckies have a bad enough perception with the public now. But it is worse when industry Leaders show this behavior on the small screen as well!
lostozzie - thank you very much for bringing this issue to our attention. We took it very seriously, as did Jim Park himself. While insisting he would never do such a thing, after reviewing the video Jim realized that the evidence against him was very compelling. He insisted we use all the resources at our disposal to investigate so that his good name could be cleared, or - if found guilty - do his penance. The resulting investigation has been documented in this short video. I invite you to view the evidence and see for yourself - GUILTY or INNOCENT??? ua-cam.com/video/Juhd2Mk_-vo/v-deo.html
Thank you so much for proving me incorrect on this! Jim you have proven you are a class act and an industry leader and my hat is off to you on the professional way that you showed us that I was incorrect! You have kept a positive image out there for truckies / truckers!
Cheers Mate!

My pleasure, lostozzie. Image means a lot to me too.
Do you lumber ? Pick a lumber from one to ten.
I'll take an 18 speed
ua-cam.com/video/aR6Foiy2Gi8/v-deo.html Yeah, is true, but here' always the 16Liter volvo's crush the 13 liter, even if they both have 540 hp, bigger engines with lower rating tend to be more economic, last longer, and they consume less becauuse they produce less heat from lowerpressures, in 15liter, most of the energy gets disipated in the crankshaft interntia instead of becoming heat like in 15 liter.
1:13 not quite more than tripled the hp of the thermodyne, 170 hp x 3 is 510 hp - 1:50 yes its torque that gets you up the hill, power is torque x engine speed, so high torque at low rpm means a lot of power at low rpm. If an engine cranks out 1000 lb-ft at 1100 rpm, another 1200 lb-ft at same 1100 rpm than the second engine delivers 20% more power at that rpm. Another example: Lets say an engine has a constant torque of 1400 lb-ft from 1000 to 1500 rpm, then this engine has 50% more power output at 1500 rpm than it has at 1000 rpm - this is how torque, rpm and hp correlate. Most commonly big displacement engines have more torque at low rpm, meaning they have more power at low rpm, stronger engine brake, and a higher tractive effort on starting, significantly important when you have to start uphill with 138 K lbs GCW . Here in Europe, trucks commonly have around 11 litres displacement and 400 to 450 hp to haul 40 metric tons GCW at (governed) 85 kph, but 505 hp and 62.5 metric tons at 60 mph in the mountains?
Yes hp is hp But what rpm is it making that hp and torque?, no replacement for diplacement
2600nm/950rpm!
Were can i get on of these
Volvo powertrain. Very good
this is sweden made components!not small block!12,8 litre is not small!this engine and transmission,many years pulling in sweden 60 metric tonn vehicles with one drive axle!in euro this engine green and black color with volvo badges and 540hp...
156k pound s in Alaska
Modern version of the Rubber Duckies truck!?
Mp8 junk good looking truck
0:48 truck driver throws coffee cup trash out the window as he makes the curve.
Well it wasn't a pee bottle at least.....
Best part of the video....Thanks !
They made another video proving that he didn't throw anything out of the window, it flew off of the truck
Eagle eyed.
@@spencers4121 bro I'm laughing my ass off at him tossing it out, then your comment 😂😂🤣🤣🤣
Anyway, the 16 liter volvo is a nasty, angry, fuel sucker, angry piece of an engine, it's pulls like nothing, it haves a bigger bore/stroke ratio than a Cummins or a Iveco, and it also consumes a lot, 6mpg at 55mph with 100.000lb
this volvo f-16 block is very strong!low fuel consumption!my friend work on12 years old volvo fh 16 610hp 625000 miles run.........one diff truck with 3 axles 26 cubicmeters tipper trailer.52000kg gross....115000lbs....at 50 mph speed 5,9mpg....40litres/100km/h
6 mpg with 100000 pounds sounds good to me
Not enough horsepower , needs a 18 speed, mp engines are trash,
