Strange Noise ... please help
Hey guys I was at the track all day today and started hearing a weird noise that one eaither wasnt there or I have never heard before.
When accelerating, everything is cool till I hit 6500 ... at which time I hear a pusssssht sound. It happens everytime at 6500 under full throtttle. Any one have any ideas?
I dont think its compressor surge as its not when I lift its only under full throttle.

I went back to the track for day two and it was now happening sometimes at 5800 rpm and 6000rpm and 6500rpm. ... if I stay on the gas it goes away but feels like its down on power a little (not a lot) and its quick ... like for a secound or so.
Someone told me it could be a boost leak from bad clamps
Someone else told me its the wastegate dumping
Someone else told me it compressor surge

It dosnt seem to do it if I park the car over night and try and get it to do it in the morning only on the track when pushing the car for a period of time or when the car is warmed up.

Do you have the stock intake? If so, do you still use the stock intake snorkel? If so, do you have BOTH clips fastening down the snorkel?

Fasten the snorkel down and it should not do that.
