  • Turbo Whine

    I have tried to search the forum to find a thread about the turbo whine when accelerating. Do I have an issue to be followed up or is nit normal. It really is a high pitched whining noise. any comments would be appreciated.

    Hopefully you're actually hearing the beautiful sound of a whistling turbo

      Agreed. Its a turbo diesel? If its the natural turbo sound - then enjoy the engine you've bought... If not buy a petrol...

        with a std vehicle you will hear a slight whistle from about 1800ish rpm, when you modify ie bigger dumppipe and or exhaust, airfilter (aftermarket) and snorkel it will whistle like a happy canary, (not a bad thing) whistle will probably appear earlier ie 1600ish rpm which means it is breathing better, this means the turbo is comming on boost earlier which will mean crisper driving and less turbo lag, which is all totally normal in a turbo diesel, wether it is 1kz or d4d. cheers samo

          Add a 3 inch exhaust and that turbo sound gets louder, all good.

                  Give the guy a break. If he has never driven a turbo before it is a noise you can hear that he didn't realise is normal. That is one thing about this forum.... asking questions to get answers

                        Hope your enjoying your diesel mate, its good to ask either way... Even if we hang a little.
                        We are assuming that the noise you are having is standard turbo whistle, if you still have concerns then best have it checked just to be sure!

                          I took your question as serious. There are some embarrassing moments on these forums including people finding (or not finding) secret compartments for sunglasses, head rests hidden in seats, stories of people filling their engines through the dip stick, putting petrol in diesels and vice versa, the first up question done 1,000's of times of question of "what size tyres will fit on my rig, etc etc..

                          Welcome to one of the best sources of information from a great group of people. Some you may meet and most you will not.

                              Thanks for the replies. I am a novice when it comes to the mechanics of engines etc. However to explain a little more, which I should have done at the beginning. Last year I did drive a 120 D4D across the middle from Broome to Port Augusta via CSR, Gunbarrel, Old Ghan etc. Great trip of 24 days however the sound of the 120 did not seem to have the high pitched whistle that my new 150 has. Samo Your explanation sound the go. I'm going to notice the sounds as you suggest. I do have a snorkel and have put in a steinbauer chip (has been a positive). Eatovelearn, I'm returning to Sydney in three weeks to get some recovery points fitted and will get Jimmy at Mannel motors to have a look at it.
                              I think this site is a real positive and as a new chum to 4WDing I enjoy and value the forum. I have recommended it to many Prado drivers on my travels around Aussie.
