Weird Whine during spool up.. (video)

[maverick_990]

Can anyone tell me what I am experiencing... Is it just a boost leak? The car is still running fine and it is not smoking. It also still builds up boost fine.. It is bugging me bad.. thanks in advance

have you checked your turbo for shaft play?

check the compressor wheel
also do a boost leak test

You have nothing to worry about maverick_990, if its boosting good,its just a boost leak.Common places to look for boost leaks are couplers,throttlebody,j-pipe

That loud wining noise is a boost leak, near the compressor.. Do a boost leak test and pump around 20psi into your system, and i bet it will be near the compressor cover!!

I was hoping it was a boost leak, my wife was worried about it being something major... tomorrow I will check it out.. thanks

I dont have access to a boost leak test, and have not put one on this car yet.. So I hope that is all it is, is it still ok to drive like this?

My car was making that identical sound at one point...ended up being a leak where the j-pipe meets the compressor on my 16g.

hm well I still have stock turbo and intercooler

Hey from what im reading im having the same problem, I cant see your video and was really hoping you could dm a link so I can see if it is, its been driving me crazy I can figure it out.

It's not okay to drive like that. Buy it off ebay, boostleaktesters.com, or make one at home depot. Boost leak test your car. If your going to own a turbo car you should have this tester anyways. The whine could be a simply leak or it could be a bad turbo. Check for excessive axial play in the turbos shaft. Some is good, a lot is bad. Any lateral play means your thrust bearing is bad. Which requires a rebuild
