What is it about a V8 motor that it makes that Ï want to buy you sound" ? I have worked on all sorts of motors from single cylinder to 14 cylinders, and yet its only the V8 that makes that unique sound.

 Absolutely! Love the sound through the 3" pipes of my V8 Cruiser,both at idle and when I'm driving it hard. The popular cars,with their sewing machine engines just don't compare,in more ways than one. Difficult to describe,but the sound echoing through the bush late at night,from the exhaust pipes of the V8 Scania Road train that I drive,has to be be experienced to be believed. When you're in the back of beyond,the big V8 just sounds sooo good!  Cheers

Hey Yobarr,

Remember the old 8V 71 chicken scarers.  

These are two strokes not 4 strokes..

 Ian,

An engineer once explained to me that V8s have a unique sound due to the phasing angle of the crankshaft.

Something to do with the position of each piston when on the firing stroke in relation to the next cylinder to fire.

I hope I have said this correctly.

Maybe Toyota just build them like that to get sales :)

I did work on flat 8's but don't remember them sounding like that. The 5 cylinder Mazda just sounds like an engine !

Stuffed my car full of acoustic insulation so I don't hear the engine.

Surely do remember the 8V71,Rob,which was a magic engine in its day! However,it took some doing to make the older drivers understand that to get the best out of those engines,you had rev the sh-t out of them.Many had previously driven such low-revving  powerhouses as Leyland Hippos,Octopus, Beavers etc where low revs are used,and some drivers never mastered the Jimmys and went back onto the Leylands!Had 6V53 and 6V71,as well as the seemingly indomitable 8V92 which was BIG gear in its day.You could hear these engines,on a clear night in the bush,from 3km away.Those were the days when trucks were trucks,before all the European stuff arrived with syncro boxes and wallowing springs to keep pansy drivers happy.Used to know a chap in the Territory who ran triples everywhere you could think of,with a Superliner that had no AirCon! "Real men don't need AirCons" he'd say when queried.Could go on for hours about trucks,but not tonight.Just finished 14 hours on the Road Train,and I'm a bit tired.Cheers

 Ian,did you ever work on a straight 8? Cheers

Nup never worked on a straight eight, but I worked on a round 9 :)

 Buick built tgem from 1931 to 1952,and they were nearly 3 feet long.Back then,a car with 170hp and stacks of torque was almost unheard of! Cheers

 Hi yobarr,

You had to drive em like you *hated em*

My old dad who was using Fodens, Ford Thornycrofts, etc you can imagine the collection,  used to say to me and others when we all started driving 6/53 and 6/ 71 series engines that we were all being smart ar$es being able to play *Annie Laurie* on the gearbox.  
A trip down the Hume in those days would involve several thousand gear changes. Around town was a real workout for your left arm as well.

I can remember when we got our first 8/ 92 rated to 79 tonne from memory. Our first road train Prime Mover.
Hell that thing used to bark on full note, music to a drivers ears.
I often wondered about those poor soles in all those little towns that put up with that noise all night from the trucks travelling the old Hume Highway.

Nothing compares to the healthy sound of a V8 ICE.

Rob I think has the answer:-

Ah yes. The sounds of V8s with modified exhausts waking people up all over the place.

That is better than dirty smoke spewing Nissan diesels with 3" exhaust or only a hotdog muffler.

 Yes, and there is a few of them around.

 Yes those bloody V8s.

That noise even wakes the drivers some times  

Then there are the trucks. Very Irresponsible. :shock:

Nope...sweetest sound ever is made by Ducati v-twins sir!

 Said every Duke owner ever   

If we are onto motor cycles, you could count the firing stroke on an AJS 500 up to about 50 mile an hour in top gear. They were a single cylinder.  

The mate of mine who actually owned the AJS used to call Yamaha bikes that were just on the market as Yamahahahahas they were two strokes back then.

 750 Trident.

I had a Ducati 750 SF (or SE?)  back in the 70's.   In my opinion, only the Laverdas were a better ride in those days.  

In an effort to get my daily dose of the V8 noise I was watching the shootout at Bathurst.

For those interested Whincup got pipped at the post which put him out of the top 10. I dont think he was that happy.

Channel 7s coverage was a bit one sided I thought. Their report for most of the week was all about J Whincup with little mention of other competitors.

Waiting patiently for Sunday. More V8 noise   although not quite the same on TV

They also made the the AJS 500 in a twin Rob. I used to ride one when I was 17 years old. On a good day it would show 92 mph on the clock with all 9 stone of me flat across the tank.
Those were the days. Landy.

Hi Landy
The single cylinder AJ my mate had wouldnt run out of site on a dark night. 
If I remember correctly it ran out of puff around 60 mph.
I was not aware that they made a twin.
Probably made to compete with Trumpys at the time.
The very first bike I had and it was around the same time, about 1966 was a Honda Dream.
If I had that bike today I would ride it with a paper bag over my head to hide my identity

Rob, I started riding motorcycles in 1967 and only recently quit. First m/c was a BSA Bantam (single cyl two stroke) in the days before yamalube (auto oil injection) so if you forgot to rock the bike in the morning to remix the oil and petrol in the tank the first kick would foul the plug with oil. Being too lazy to pull the plug and clean it I just pushed it for a bump start, they kept you fit back in the day, and coming home from work after dark the lucas electrics (prince of darkness) were always waiting to pounce.

 Mate, you are really bringing back memories now.

When. I was going to Tech there was a kid with an ex army Harley.

During lunch break he dropped it while showing off to the girls and  he couldnt pick it up by himself . That was a little embarrassing for him.

I probably should apologise to Ian for taking this off topic.

Back to the AJS, my mate and I were courting a couple of sisters that lived on a rural property. Their Dad had a couple of pretty angry Billy Goats that were tethered to a couple of star droppers in the ground.

He dropped the AJS on the blind or high side which made him within striking distance of one of the billy goats. That was funny watching him pick that up.

Haha! he sounded a bit like a V8 that day.
