I Found Out How To Make My Turbo Whistle Louder! - Page 2 - PeachParts Mercedes-Benz Forum

I recommend not putting holes in that flex pipe. Mine went last year on its own and it was LOUD. Your also correct in that the amount of dirt and soot in the engine bay is just not worth it.

Mine also did not have a pipe within the flex.

Wow, some of you are making it sound like my car is loud and obnoxious, when all I did was make it so that when I'm accelerating I can hear a slight whistle, just enough to let me know that the turbo is functioning--and I think it is a pleasant sound. It's not even audible when the radio is on.

Even when I had the exhaust removed completely it wasn't nearly as loud as those Cummins trucks or street racer cars. Some people on these forums are much too judgmental. Half the time I feel sorry that I ever post anything.

i only hear mine really when it's spooling between 2300 and 2500. then it gets quiet and GOES.

just kind of a shwoosh

Removing that sleeve for more noise, well seems foolish since it is likely there for better airflow = better power.

If you want turbo noise, go to a cone air filter. There is PLENTY of turbo noise on the intake side of the turbo, I can hear mine when driving 75mph with stock exhaust, stock air filter system, just a pipe replacing the AFM in the intake plumbing. We put a pair of BMW/Yanmar turbodiesels in a mahogany boat (Hacker-Craft reproduction) we were building, when we did the sea-trials the Yanmar guy showed up with earplugs, ... the sound from those big turbos' intakes at full-chat was DEAFENING! (3L inline 6 running 250hp).

I agree with both camps really. I love the sound of the turbo, but in my car it seems to be its loudest around 8-10psi, which is right where it runs at 80mph. It gets annoying. On the other hand, I've always loved opening the window on our coach next to a concrete barrier to hear the turbo spool, ... 45feet behind me.

if you are determined to hear more of the engine, take out some of the floor mats and whats inside the hood.

it gets old quick :/

I made a newer cold intake than what my photos show.Filter is at front in the cold air.Some kits they sell are really hot air intakes.
That and straight exhaust plus boost at 16psi,she really sounds good.

If I listen closely with the radio off I hear what sounds like a muted siren off in the distance as my turbo spools up. It works quite well and seamlessly.
Also- it looks to me like that inner sleeve is there for heat-related reasons. My car still has it.

I wish I could hear the turbo spooling in my 240D, but it sounds like it's not there at all

The CDI's are so quiet, you can barely hear the engine, but the turbo sound seems to be quite noticeable, particularly on the Sprinters. I've never been able to hear the turbo whine on any of the IDI Mercedes turbodiesels except when the exhaust or intake have been modified (i.e. K&N filter and/or straight pipe exhaust). I've always wondered if that was an intentional design feature as the whine was an "undesirable" noise for most people.

I haven't noticed any power decrease from the pipe being removed. I might go with a custom air intake, but will do my research to make sure I get a good setup.

The only parts I removed from the 280E was the first aid kit, manual antenna, and tool kit. I'm glad to see others are making good use of the parts. I've seen too many Euro W123s with nice cloth interiors get crushed without anyone buying the parts. At least I got the 5 speed from one before it went away (it's sold).

I don't want to hear more of the engine, just the turbo. I'm not even wanting it to be screaming in my ears, just lightly audible. I have a turbo and want to hear it like the Cummins guys.

... Or just make zoom-zoom noises while driving.

tbomachines · #11 05-28-2011, 01:16 PM

This thread is too funny - a bunch of folks comparing turbo whistle to rice burners, harleys with no mufflers, etc. Its turbo whine..

#12 05-28-2011, 01:21 PM

It's just silly.

Turbo noise is annoying, especially on trucks. My ideal vehicle would be silent.

I really wish that people would keep their negative comments to themselves, though. There are lots of things I don't care for, yet I don't go around saying "that's stupid" to everything I don't like. I guess some of you shouldn't be driving diesels if you don't appreciate the sounds that the engines make.

Most of these Benz forums are made up of Aryan worshippers of cars.
They think its unholy to custom a Benz.They don't understand it will rust and decay like all cars one day.
But remember they are alot of customizer and engine builders that can make these cars even better.I'm with you.

It's quite interesting because I tend to be a purist overall but sometimes I like to customize here and there. In fact, most people who know me say I am too much of a purist. But then I find that in the rare instance that I change something from stock (even going to Euro lights) I get slammed all over these forums. It's a bit odd.
