dang these things are quiet
 

I was at work at Sonic today and I walked past a 6.7 and it took me about three passes to realize it was running! Granted there was some ambient noise but still.....

One thing I like about the LML is it still sounds like a diesel, they arent any quieter than the LMM's.

cool

I wish there was a sonic near me.

Guess that you won't wake up the neighbors with the 6.7 & as a side bonus, you can sneak on you wife when she cheating on you with the neighbor:tu:

I always thought the Wat-a-burgers were ok. Rods Sausage cheeseburgers are still number one in my book! Can't forget about Webers rootbeer, I forgot about the ol burger shck in the down town area behind where Chris Nickols used to be? I mis those places.

No comment about Sonic :w2:. But I agree with the quitness of these engines. I was doing a sales call at a local RV dealership and one crep pass me. I had to take a second look to see weather it was a gasser or not. I know H&S has some vids on this truck with all the deletes and it's still pretty quiet. Especially compared to my a stock 6.4. I guess that's the way Ford designed it to please the treehuggers :moon:

Funny thing? Tree huggers love diesels!:humm:

My neighbor has one and when he takes off and stands on it going up the hill it sounds like a jet taking off. :c:

Don't you like the quiet diesel engines:humm:

No hippies love vw diesel and treehuggers love toyota prius'/ any subaru(cause it's a ruged suv to take me to my tree, wait it's a car for the 99.99% of time I spend in the city, wait it's japanese so its reliable) lol I still haven't seen a jap vehicle reach much pass 500k miles.....Back on topic.

Mike Rowe promotes that they are quiet so you can leave them running and still have a normal conversation while standing next to it. Strange thing is with how loud he is I could still hear him fine when he was standing next to the dmax. :humm:

The engines out there are great for trucks. What they need to do is start investigating into more diesel suv's, 1/2 ton trucks, and cars. Dimlar(not spelled right) did it with Jeep and sold out of them as fast as they could bring them into production. Then companies start looking at batteries...here's your sign.

I'm a tangent maker! :hellox:

Never said I did or didn't like just sayin what it sounds like :c:

Oh they're investigating it enough, they just wont throw one into production :dang:

I think the problem is not too many women care about diesel:humm:

Maybe not in FLORIDA but here in OK we have a few of them :hellox:

And how long have you been a mod? Just noticed that.

Since MARCH 27, my wife doesn't want a diesel, And I told her diesel don't smoke or make noise like they use too:nope:

Well congrats :tu: If Im still hanging around here in about a year Id like to try for a mod position. Im going to try to get premium membership before the months over.

And I was thinkin you could get her one that was really quiet and just tell her it was gas, but then what happens when she actually puts gas in it? lol

I wasn't happy, when she bought her new HONDA ACCORD EXL V6, but it's her car & she'll be driving it

The "quiet" diesels are just using a Benz method of making the engine quieter all while making a more powerful powerband. Basically it injects a teeny tiny bit of diesel in to make ignition and then the rest of the diesel to make the power stroke work. If you inject all the fuel at once then you get that diesel "knock" before it ignites. If you put just a little in the knock is quieter in getting that little bit of fuel lit up and then the additional fuel doesn't knock at all. Its not an environmental or treehugger thing - its for more power and quieter engines.

It's hard to believe how much diesel engine technology has progressed in 10 years. I like the new engines to an extent. Quieter diesels are good and all but, for my money nothing beats the sound of a proper diesel engine. I have owned an 04.5 and 06 dodge and while they are by no means quiet by today's industry standards, but they are still to quiet for my taste. I am currently trying to work a deal with a friend of mine for an 01 dodge. I will gladly let that 24 valve sing to me anytime, with the equipped dual disk accompanying the straight 6 symphony.

i'll take the quieter more powerful more efficient diesel over a "proper diesel" any day :rocking:

I have a radio for sound.

I personaly like the older louder diesel's. The older diesle's were better on fuel. I have owned every diesel ford put in a F series except the 6.4 powestroke. Best on fuel for a ford was a 97 powerstroke.

I have had ever diesel in a dodge except for a 12 valve. I has a 2000,2004,2006,and 2010. Best on fuel was the 2000 Funny each truck got quieter with cleaner emissions and the milage went down.

but do you understand why the older diesels got better mpg? not because they're mechanically injected and clattery. because they didn't make the same amount of power.

if I detuned my 06 duramax from 360hp/650tq (stock) edge on level 1 +30/60 (idk) that gets me 20mpg down to the levels of my first gen cummins that got 22mpg 160hp/400tq stock but with the fuel turned up a bit so prolly closer to 200hp/500tq

so.. if I dump half as much fuel in the duramax to bring it to the level of the old cummins.. would i gain the difference of 2mpg? or a hell of a lot more :humm:

I would compare to a ford for you but the only one I ever had was a 6.9NA motor, and my friends 96 powerstroke only gets 14-15mpg best so it'snot really a fair comparison there.

.

i get 18-22mpg with my rig and it makes 415rwhp...... hmmm thought these newer diesels didn't get good mileage??:hellox:

Rattley old diesels are way too annoying to drive and try to have a conversation with anyone in the vehicle with you, I have an old mercury capri 5L with glasspacks if I want to be deaf and and have a headache, I'm quite content with my quieter Duramax thanks

To the fellow who commented on the pre-injection, that Idea has been around for quite a while, and I'm pretty sure that it was Bosch who came up with the technology, not Mercedes, with High pressure common rail and solenoid/piezo actuated injectors they are able to achieve more pre-injection events, with a finer spray which allows for better combustion and less rattle, its all about controlling the combustion event, and the new technology allows for that precise control, older mechanical injected engines just can't do that

:scare2: :s: :scare2: :s:

They are quiet and nice.

Theyre not near as quiet with a 5" turbo back :choochoo:

Helped put one on a brand new 6.7 the other day, everything deleted off, H&S BlackMaxx, and an EGR delete too. I want one :dang:
