New whining noise under acceleration

[Jonny]

I have just put 8mm spacers on the front wheels and added the Pipercross stage 2 pipe to the back of the Neuspeed Induction Kit and now the car makes a short high pitch whinning noise when the car is under hard acceleration around 3000rpm. I can't work out where the noise is coming from. Has anyone else experienced this problem?

Its all sorted now. I found out where the air leak is coming from.

Would you mind pointing it out just in case someone else has the same issue?

Thanks.

One of the pipe is not connected very well so I have ordered a new hose which will give a much better connection. Because there is a small gap when the boost builds it makes a whistle/whining sound but then goes away under normal driving. Hope that makes sense.
