    Default Boat issues HELP!!!

    Right, I had my turbo sent away for refurbishment and a new hybrid turbine installed. Came back looking amazing and then got it installed. All fine and found to have much more power and boost kicked in a lot earlier. Later that night I was going about 20~30 mph and put my foot down in 3rd and changed up to forth. As I changed up I heard a loud whistle and now every time it's boosting I hear it whining/whistling. I've checked all boost pipes can't seem to find it leaking anywhere.. Could it be the recuirc valve? As I heard they are pretty poor and with the added pressure could it be that?

    Any help would be greatly appreciated!

    Worth a check on the recirc valve but they do not usually whistle well mine did not when it split on last car you just lose lots of power and runs crap , when turbo was installed I hope it was primed with oil first if not kiss it goodbye.

    Yes it was matey, I did it myself 😊 and I've checked the turbine still spins freely and no play in it.

    It could be the recirc valve as you say, they are known to split

    My turbo had an odd whistle that I couldn't track down and it turned out that the compressor wheel had been damaged and was shaving itself on boost, hopefully your issue won't be as serious especially on a new turbo

    That's what I was thinking but I don't know if that would cause the whistle. Yeah let's hope it's not the compressor wheel 😂. How did you find out in the end it was the wheel?

    I pulled the outlet hose from the turbo and found it was full of shavings. After finding this I pulled the inlet of the turbo to verify the suspected damaged and unfortunately I was right

    Oh right, I've had all my hoses off and not found anything like that luckily. I'm going to pressure test it tonight then hopefully see where it's coming from.

    Did you fit an uprated turbo without getting it mapped in???

    Yeah, but it is booked for a map and though it would be okay to drive until it's done?
