Odd sound at full throttle?

[chariot124]

Hello all, I just bought a 05 WRX. And I just noticed that when I give
it full throttle, there is a wooshing sound. Like air is being sucked
in our leaking out. I was just wondering if this is normal... there is
an aftermarket blow off valve on it and I think maybe is not adjusted
right or maybe there is a leak somewhere.
Thanx for the help!

You sure it's not just normal induction noise? Sucking in 100 litres/second
makes quite a bit of noise... Perhaps look for a leak in your air filter or
ducting...

Best to get rid of that blowoff valve and put a stock bypass valve on.
The aftermarket BOV's tend to leak and can make the car run worse,
especially if they are the vent-to-atmosphere type.
