1. Already done, sadly, this recording has a couple blips in it due to a wimpy laptop... :rolleyes:

2. Host it on my own server: My Engine Right click the link and do "save as".

3. Enjoy! :D

it sounds like a really used gas engine to me.

but to ask the question i replied to ask...:P i use a macintosh g3 ibook as a portable computer, thatll let me record the file in .aiff and 'windows wave' format.

i am assuming that a 'windows wave' file is a .wav and youall will be able to hear it more readily if i use that option? i dont mean to take this off topic, but do windows machines play .aiff files?

ill go and start it so youall can hear the beasts that live inside my engine compartment and beat on things with little metal hammers... and just generally make my life a little more musical.

Windows .wav will be more accessible to the masses.

Check here for a video from inside the E300 Turbodiesel.

maybe someday I'll make a recording. But as my neighbor says, "It's growling at me!"

.........ahh........you better clean out those chipmunks before you make that recording........we'd all think you screwed up that rebuild..........:D

Wow
 

Five MEG file.:)

Sounds like (pause) Victory....

Here's a sportier (albeit reckless) rendition of my 3.0 liter 603.

http://www.ejzcars.com/OM603.mp3

I can also make one of my of my 350. Recent files will sound absolutely horrible.

That does not sound like a 603. Too much clatter at idle. Doesn't smooth out when revved. What's the deal??:confused:

That idle doesn't sound that clattery to me ... I mean the idle about halfway-3/4 into the file ... that sounds about like my car, which as far as I know, sound healthly. :confused: I definately never sound like the rest of the file though ... what rpm is that thing running?

how does my diesel sound?? LOUD!...

small file.. AMR format.. can be played through Quicktime

Yes, please
 

Yes, please.
We need bad and good sounding engines.:)

This can be used as a diagnostic sound library.:)

I'll make one up of the 300SD. Since I seem to have one of the few 617's that redlines at 5400-5500 RPM under load...might make for an interesting sound clip! :D

...and yes...I've inspected the bottom end...

Not a Mercedes but still a diesel

This is an animation on how it works. Open about 5 browser windows at a time and they will all fire at different rates, kind of sounds like a 617 in slow motion.

I'd recommend that if you are going to start copying other people's work and diagrams off the net, you should probably give credit to where you got them from.

I admin a website and its a regular task to make sure to not be using copyrighted materials and give credit to other people's work.

Just a thought :)

BTW we've discussed that animation before...its pretty inaccurate as in the fact that the pressure is INCREASING the full power stroke on the way down and the heat seems to decrease entirely on the exhaust stroke? Hmm....

I never said I made the diagram. The point was to get 5 going at the same time for something fun.

I dont even remember where that diagram came from or who created it. Lots of people in diesel land use that diagram. I guess they should have put some kind of webmark on it so we know who made it.

You find out for me and I will give them credit.

Its just a basic animation, not an engineering paper. It was probablyu designed for those that dont even know what a diesel is.

Took me about 4 seconds to find it:

and if you look below the graphic: "Image courtesy Baris Mengutay"

If you hotlinked to the page that is one thing, but copying and posting on your own site, you need to give some credit to the guy who made it :) Guess I learned something from college right? Hehe. Not citing sources = bad :)

Yar she blows ... this may or may not work. It may or may not be the worst recording in the history of audio devices. I used my cheap reporter's recorder (my company doesn't pay for our recorders ... ) and then played it into the computer's speaker, so it's doubly bad in sound quality. The first 15 seconds is a cold start (sitting 10 hours overnight, started early morning about 25 degrees out) and the recorder is sitting in the engine compartment. It sounds like a Cummins that got kicked in the nuts. The last few seconds are after warming up for about ten minutes, with the recorder held outside of the driver's door, hood open.

I don't think my engine sounds this bad. :eek:

(now it works, thanks to Brandon!) :)

Oh yeah, my recording is all at idle (probably obvious, but why not state it anyway?):)

Your link is dead hun :)

If you can't find somewhere to host it, you can email it to me and I'll post it up for you on one of my sites. I have a bunch of hattie's pics up there right now :)

LOL ... I think I could figure out how to replace a cracked head faster than it would take me to figure out this freakin' audio file. I'll try e-mailing it to you. :cool:

The not smoothing out is due to the injectors cracking when the engine is blipped. As far as the idle, know that the camera (I have video) was not used outside more than 15 feet away from the car. Most footage was taken inside the cockpit with the window open, underneath the hood, within half a arm's length next to the CC actuator, and the furthest, about 15 feet southeast of the engine bay.:)

That's interesting. I think the recorded sounds are different than the personal observation. It just sounds louder and closer to the 617 noise than either of these two. I'd make a recording of them but I don't have the gear.

I think this may be what it is. Let's face it, none of us are probably using professional recording equipment. I know the recording I made sounds much more clattery than I think my engine does. The acoustics are just different. For one thing, it doesn't have a great range (my recorder), so when I placed it right in front of the fan, it picked up a lot of the belt noise ... plus the engine, plus my apartment's AC unit off in the background, plus the wind, plus random background white noise. :)

Was your video done in a garage? It kind of sounds like some of your loudness may be due to "indoor acoustics."

my OM617..shes 23-24 years old now with some 122,570 on the clock

and yes the engine is a greasy pig!

Here is redline in my 300SD...and what it sounds like :D

I dedicate this movie to Brian :)

(BTW yeah my speedo is accurate...its out of a different model and with the tires I am running its spot on as far as ground speed is concerned. :))

Enjoy.

Here is my 350, during recent times.

http://storeandserve.com/download/63843/350start.mp3.html

Wow. I've never heard one sing that high before.:eek:

Is that actually 5700 rpm in second???.................on a 617???.............:eek: :eek:

I still think I can't believe it.............truly amazing!

And, it appeared to be pulling well over 5K.........where the torque should have fallen off dramatically.

Yep...2nd gear :)

It pulls okay but you can feel the torque drop...when it reaches 5700 it lets out a huge belch of smoke as long as you stay on it...defintely fueling!! :D

Have you run a recent 0-60 with it?? Are you down to 11 seconds??

Had to unplug my tank vent...that thing seems to get plugged up often when I drive through lots of mud. :)

Its running pretty solid now...I need to bring the ALDA back up a little (I had adjusted it down to take care of some smoking but went too far).

I'll do 0-60 here after I get the ALDA all set up nice. I'll post on the other thread what the performance is :) THen I'll up the fuel some more and repost performance :)

Here's a video of my '84 300SD. Running cold. Dash thermometer said 12deg C.
http://i1.zvhost.com/1/q/q1h2aece.jpg

Here's another video 1/2 hour later running hot.
video 2.avi

There is a little bit of exhaust smoke but I don't think it shows up.

Blowby....good :) or bad :( ???

Danny

Do I hear some sort of knocking/hammering when cold? Sounded like there was something more there than just diesel clatter/cold engine.

I guess the warm video would show ;)

Same question as Brandon
 

Brandon, I thought I heard the "some sort of knocking/hammering" also. I am curious because my 87 sounds the same way when cold. If I rev it up past 1000 RPM the knock goes away, and then comes back when I let off. Once warmed up from a little driving it is not there at all.

If the answer from dannym is yes, what could it be?

Mine runs great, burns no oil, has no blowby, and gets 26 -27 MPG on the highway. Any ideas?

Thanks,

Clay

Mine hammers when it is cold but its clearly upper head clatter...not bottom end clunk.

Maybe get under the car when its idling cold and have a good listen. Its something difficult to pinpoint. If it goes away at all RPM's when its warm I guess its nothing to worry about. :)

You know I never had anything to compare it too. After hearing some of the audio clips from this thread I am kind of relieved. I always thought it was too loud and knocked a lot.
It get's 25+ MPG but I'm sure it could use an injection pump timing. I may just wait and roll on a new chain this spring. It definitely sounds better when warm. I'll add that video tomorrow.

Nice video of your car....is that a manual?

Danny

Nope...it would be a chore to speed shift that engine without wasting the tranny at 5700RPM :D

Its an auto 4...like almost every w126 body :)

I was wondering about that. I thought I saw you shifting in your video.

I just posted a video running hot in my first post.

Danny

Well the transmission would want to shift at 4300RPM or whatever if I let it...so I was basically holding it into 2nd gear. (thus you saw me shifting out of 2 into S)

New exhaust on a 300SDL *VIDEO*
http://www.peachparts.com/shopforum/diesel-discussion/111222-new-exhaust-300sdl-%2Avideo%2A.html

I've gone up to about 3mph past the 2nd gear-shift dots on the speedo with mine when I left it in 2, and I've easily spooled out to around 77mph in 3rd in "S", the 3rd gear dots are around 71....and it had more left. :eek: Its scary when they are rev'd so high. 5,700rpm, thats crazy!! :eek: Aren't you worried about blowing a rod/bearing or something??

Our 83 rev's all the time, if you do pedal to the metal it holds every gear up to nearly 5000rpm before it shifts, it also has gone over 80mph in third before when merging onto the freeway. The 5100+ rpm category just seems....a bit on the daring side.....

When I replaced my oil pan/gasket (the old one was rough/leaking) I gave everything a good inspection/wiggle. Everything is solid.

I always have my ear out for a light rod knock, noise, something...but the only thing it gives me is some nailing on cylinder 1 when its cold heh.

It really likes reving up that high...I think the diff turbo compressor/adjusted fuel helps it stay torquey on the top end.

Its a nice sound :D

A diesel engine torquey at 5700 RPM? What have you been smoking Brandon?? :P

Watch the vid. :D Its a LOT more torquey at that RPM than it used to be.

But yeah...not like a gasser. :)
