We all love the thump and cackle of the V8's but not all know "why it is so" It's caused by the firing order, two cylinders firing consecutively into one side exhaust manifold, then same on other side. Powerstroke Fords rumble for same reason, even Subaru WRX have a low rpm high torque uneven sound for same reason. Check out various firing orders, quite interesting. Cat 3408 have offset con rod journals resulting in slightly uneven firing giving a unique sound. Great music thanks.
@@danielcont95All V8s have two con rods on the same crank pin. The firing order gives the exhaust note. There are a lot of different firing orders for V8s which makes them sound different. Also a smaller V8 on the same firing order will sound slightly different to a bigger one. Straight 8s sound different again.
Two cylinders don’t fire consecutively. Subaru motors have their distinctive sound because they are horizontally opposed. Harleys sound the way they do because of their crank design and the angle between the cylinders.
@@jefftheaussie2225 Yes you are right the Mack V8 was about 19 litres versus 13 litres for the Detroit. The Detroit was more popular there is still one coming into my work place everyday in Port Melbourne in a old W model Kenworth rated at 475 hp & it sounds absolutely amazing. Both the Mack & Detroit sound amazing there is also a V8 Caterpillar in a Peterbilt here in Melbourne working as a mini B Double working everyday that I hear under load every second day & that sounds out of this world
@@WildWildWeasel When I drove for “Transport Services “ All their Mack R models had Air Starters! Worked great when it was reasonable warm. When it got cold 🥶 No Ether NO START!
Music to my ears.
Love listening to that CAT turbo whistle on the shifts!
Kinda hard to do a u turn on a mini roundabout i guess! lol Proper trucking!
I've previously watched all these videos before your great combination of them!
Man i love that sound thank you
Why would anyone spend money on illicit substances to get a fix …..listen to this orchestra all in time 🎶🎶just hypnotising
Honestly the best comment I’ve seen all year
I remember as a kid my grandfather drove a bonneted marguris deutz V8 they where big truck in there day and sounded pretty cool as well
i laughed by the time i saw the lead up to the round about i recognised where this is, joys of growing up in the area.
The blue KW and the blue Super liner were my favourites, the other ones were nice too!
That's quite a super hi way your pulling that Cat through?😂
God DAAYUM i love the sound of a V8 truck
Great video full support
Liked the 903 Cummins as well
V8 Mack, not a 903. The 903 was wonderful but they were long gone by the time of the Big Bopper in the Super Liners.
@jefftheaussie2225 Yes, l know it's not a 903 cummins l just said that l like them drove a 3070 acco for years

@@jefftheaussie2225 cheers mate, you clearly understand engines while I’m just starting to understand it
Thankyou for info
Great tech talk.
There's nothing like an air starter.
Unless you’ve got an air leak.
Awesome video but you forgot to include a Scania V8,
Mercedes Benz V8
Iveco V8
MAN V10
Detroit Diesel 8V92TTA
Cheers
Louis Kats 👍
Mack and Scania V8
This is all about the Big Bopper V8 Mack. A real truck.
@@jefftheaussie2225
That is nice but I dispute that notion.
Scania V8 or a Mercedes Benz V8 ain't nothing to sneeze at.
Any thoughts on a V8 Detroit?
@ Detroits didn’t have the huge low down torque of the V8 Mack motor.

Where did you get all the great shots of those magnificent Super Liners working hard? You don’t see them on the road any more.
All the links are on the video description
Sounds like a big power stroke/ t444e
That’s not a V8 Cat, it’s a big bopper V8 Mack in a Superliner.
Except the little 3208 in the Kenworth. Should have watched it all. It had a Mack air starter on it though.
@@jefftheaussie2225The blue Kenworth have the 3408
I thought I saw a Putty Cat
You did you did 😎😎👍
sure are a lot of e9's down under lol
