So i'v had my fd for a few weeks now, but havent had much time to drive it recently. I took it out for a spin tonight, but found that when I get into boost it starts to make a strange wooshing sound (around 5psi). also I don't think it was boosting all the way, although i didnt push it after i started hearing the sound so it may be. I took a glance under the hood, but didn't notice anything blindingly obvious. I didn't have time to deal with it tonight but am gona try to check it out tomorrow when I have some time. I was hoping someone might be able to give me some ideas to narrow down my search, or at least some good places to start

Cheers,
Dale

 

You need to start with the Boost Test before anyone can offer any real help:

Yea, I was just a little worried about going WOT til redline with strange happenings under the hood. It used to hit almost 11 psi, tonight, I went to at least 4500 a few times and never saw over 9 psi, bit I'l start their tomorrow

Thanks

 

Try checking the hose and coupling at the Y pipe and cross over pipe. I solved my 2 year boost leak mystery with the same distinct whooshing sound by doing this.

 

^Agreed. Check the couplings on all your intake pipes, but that's the most trouble prone.

 

+1, sounds like a boost leak.

 

Right on. The coupling that goes to the IC intake pipe had a crack I could put a finger through. I think its safe to assuem thats it, now I just gota find a new one.

Thanks

Can't remember for sure but I THINK 2. 75" is what you need.
