start with the basics. check all the fittings. Sounds like a leak to me. Trust me, I have owned many boosted cars and it usually ends up being something simple.

 

I’ve had a whine noise also ever since I had the turbo installed (8 months ago) however its not as loud. The shop that did the installation stated it was normal to hear that whine out of the small greddy turbo..

What does your boost gauge say while you are at idle?

 

sounds like a belt is rubbing on something. it increases as RPM's increase. something is either rubbing on the belts or on a pulley. check all your wire harness, intercooler piping. that's my guess.

 

one thing i still havent done is install the one way check valve on the jet fuel mix hose i ordered one i should see it tomorrow...thats where the check valve goes correct? think that might be my issue?

 

i dont have the boost gauge hooked up yet....i checked belts for clearance issues none at all and i didnt touch the belts either

 

does the sound happen while sitting still and the engine revving? or just in motion?

 

while the car was outside it was making the noise while sitting and revving but once i pulled it inside the garage and revved it no more noise

 

first two videos did not sound normal. something is off.

the third one sounded normal - there is a high pitched sound sometimes as air passes through some hoses.

 

i can't exactly tell where that sound is comng from

 

i called greddy tech line and they seem to think its my bov that might be bad...im thinking of placing a block off plate between the bov and the gasket and removing the vacuum line that goes to it

 

Is your turbo getting oil?

 

Also, I was thinking about it, and are you sure that there isn't a piece of trash caught in the inlet side of your turbo? Sounds like its rubbing against something.

 

not sure, i inspected the turbo and all hardware before installation, i think im
going to block the bov first and then check for boost leaks if that doesnt work im going to remove the turbo and inspect

 

check you turbo your loosing air from the housing pipe

 

^^will do, so check the outlet pipe for leaks?

 

It makes perfect sense that your BOV is making the noise.

 

well i tried to block off the bov and no difference, i also disasembled the bov to inspect the diaphram and looks good as well, so now i think im going to rig up a pressure tester and fugure out if anything else is leaking

 

update! i lifted the car up and started inspecting and happened to try to remove the vacuum line from the wastegate to the outlet pipe of the turbo and low and behold very loose at the flange, the two bolts at the flange i was able to loosen by hand, im going to wait till the car cools down and try it again, hope this does the trick

 

hope that fixes it!

=)

 

Good luck Greg!! still deciding on mine =/....

 

hey another local!

 

update...just came back from a test drive and its fixed! looks like that loose outlet pipe was the culprit...def..feels like a turbo car now...thanks to you all that have helped me on this board...and the local guys that lent a hand wrenching and with tech info and big thanks to sammie at jrx rotary for tollerating my tons of phone calls couldnt have done it without you!

 

I can't help myself... Rather see the MM/BHR Turbo kit or used greddy turbo kit with MM turbo upgrade kit than screw around with the greddy turbo kit by itself.

Still, "mo power is mo power", greddy or otherwise.
