Not trying to be dumb...

I know of the extra exhaust valves...

But my buddy has stacks on his, and it sounds soooo MEAN...

Where mine sounds like a semi...

Does it have to do with the fuel pressure?

24v's sound a little better too...

personally i like the way 12valves sound with nasty cam.

That is good, if I remember correctly the general consensus is that the sound preference is the other way around.

its due to the injection of the fuel into the cylinder its not all at once there are multiple injections to lessen the sound of the combustion event. that is why the CR's run quiter and idle smoother. it also has an effect on the sound of the exhaust.

I think the 24V's sound the best. More Tractor/Truck like......but I'll settle for my CR.

I wish my CR sounded like a 12valve. Of course, a buddy of mine put stacks on his CR and I really wish my truck sounded like that too.

IMHO 12 valves sound like crap...wait they are. Seriously though they sound like junker vehicles...

junkers running 10s?

Sounds like a junker to me...

personally, I like the sound of an old 12 valve, but they are getting harder and harder to find

I like the sound of the 12 valve, it sounds more like a semi than anything out there. Straight piped CR's sound terrible in my opinion but put a good exhaust on them and they sound sweet.

You happen to hear about the CR breaking 1100HP????????? Seems to me that with only 4 years of development they have smashed the 12V. I didnt say i didn't like the 12V but really...they sound like their broke.

Pooter

I have yet to hear any CR that sounds better than the worst 12valve ive heard...

I miss the sound of a stacked 12valve 5spd rowing gears, and the growl/hum when slowing down or cruising down a hill in gear, best sound ever.

I think it is more the fact that they have come so far along with diesel performance that if they had the stuff now they had back then it wouldn't have taken very long to get 1000+ out of a 12, say back in the early to mid 90's for instance.

As far as the sound, you're right...generally it is the other way around. I loved the sound of the 12/24 valve engines. Then I started liking the 3rd gen more. I still like the way my truck sounds, especially under heavy fueling and lower rpm's, but it still doesn't beat the older trucks IMO. They sound more like big rigs I think. I will have a 12v one day.

Wow, what a mature and well versed response!

You must teach me!
