Diesel engines are notoriously noisy when operating. You should hear a light fluttering noise from the turbocharger. When you accelerate and the revs rise, you may hear whats known as a turbo whistle, which is a high-pitched whine. The turbo flutter isn't really all that bad, kinda soothing.

So today I replaced my power steering gear box because the dow on the pitman arm snapped. I love the whistle and growl I get. Isn't the "flutter" referred to as turbo surge? get a BD guard or type bov and it will be louder and safer. Your email address will not be published. I had bad turbo flutter when I had the Injen SRI also.The flutter went away about 90% when I tempararily went to the stock pipe connected to a 3" cone filter.It sits like the AEM sits in the engine bay.I'm putting in the jmbperformance Ultimate intake soon.I started to think that the large 90 degree coupling that connects the injen SRI and turbo was collapsing under high vacuum.If I had the Injen now I would try to put a large spring in the coupling to stop this.Try revving the motor using the throttle body and watch the coupling???? You need to choose one that suits your car's engine and not too low. Didn't unhook anything expect lines going to and from the gear box. Is there any way to get rid of this without putting the stock air box back on? Enjoy your new-found power. About Us - ?Just a thought.I heard a more free flowing exhaust helps also? Consequently, in order to achieve the same amount of boost as it would under less extreme conditions, a turbocharger needs to work harder, spin faster, and compress more air. This i just my opinion, some one else may know more than I do. A former co-worker had a air box he put on his 2005 6.0 and as soon as he put it on he had issues with chatter. The mechanic says it sounds like the exact turbo flutter issue they had with the 6.0L engines. And if that is in fact what it is and the tech doesn't know that you need to find a new dealer. I would double check that. ******** width="480" height="385">*********>. Sound right? The clipped turbos help with it a little. I got the stocker still on and it is still there. I don't know why or how; but the V8 configuration is the culprit, a Dmax sounds like the PSDs. Exhaust gas from the turbine is attempting to be utilized, but the turbine is unable to do so. So instead of using EBP input, the way late-2004 and up engines do, 2003 use MAF, A/C on-off, MAP and other PCM inputs to determine VGT output. (Is this 'turbo flutter'. There is always the possibility that the turbo flutter is normal for the combination of modifications, non-OEM calibration in your truck. That is completely normal. I'm now considering the EBPV surgery. Hello, I have an issue with turbo flutter when accelerating (usually under load). As long as your BOV is able to vent with a whoosh at high rpm and boost, it is safe to set it up to flutter at low rpm. About Us - I have read several posts on this board and understand that when this happens on deceleration it is normal, but on acceleration it is an indication of a problem. JavaScript is disabled. How's it goin Stu? Also big reduction in fuel economy. The purpose of a Turbosmart BOV or BPV is to enhance the turbocharger systems performance, not to harm the engine. Maybe its not even "bark" he is referring too. Do Not Sell My Personal Information -, By logging into your account, you agree to our. Save my name, email, and website in this browser for the next time I comment. This means MAF readings that go out of whack WILL affect turbo boost command. well sorry i wanted to get in on this real quick, do they make a safe way to eliminate turbo bark, which to me sounds like the choo choo choo choo, am i correct, i didnt even realize it was bad and i get it a lot out wheeling. Come join the discussion about performance, bulletproofing, modifications, classifieds, troubleshooting, maintenance, and more! ill try to get a video, Turbo flutter itself isnt good.

He took the truck in and checked it over, cleaned up egr valve and said that basically it isnt "reading" the turbo says 03 had reprogram and doesnt use backpressure sensor and thinks the k&n may be part of the issue (too much airflow?)

I used to try my best to not make it flutter but that seemed to make it flutter more. The consequent back pressure forces the air back through the turbine blades. Advertising - So do you think putting on the stock airbox and filter and doing the turbo learn procedure is a good idea, still?? rev rev, whoosh. #7. I also notice you're using one of those K & N air intake systems. Contact Us - Any thoughts? -jake. Another possible explanation is that the air filter in the intake system filters the intake air before it enters the BOV. Like a helicopter and I can hear it very clear when passing a semi truck or wall. at highway speeds, under heavy load, the turbo will flutter. I think a lot of it has to do with it being a V8 compared to an inline 6. It does sound cool though! 2003 model years that have had the PCM reflash under Ford's 06E17 program use what's called "inferred EBP" to determine the appropriate turbo boost needed under varying condtions. Modern diesel vehicles can be equipped with a sound booster to simulate the sound of a powerful V8 petrol engine. My truck is straight piped and has a gutted EBP vavle an it has almost no fluter, Lulu.both Avatars are Quad.hehehe. they said "theyve never seen a stock turbo create so much boost", and said that either I have a stuck wastegate or i have an aftermarket turbo.
