I just bought a 90 TT, it has a modified axhaust along with intake and stage 3 chip upgrades. The turbos put out about 13psi @ full throttle. The only problem with the car is that if I accelerate slowly, I hear this "hooting" sound when the boost needle is at 0psi or thereabouts, if I punch it or step off the throttle, the sounds goes away. This happens on all gears and at any speed. I tried to look for the problem but have been unsuccesful thus far. Any suggestions on what could cause this? Is it normal? Thanks. Fredo.

 

recirculation valves
the "honking" is kinda normal lol

 

if it sounds like this: http://www.streetneeds.com/uploads/v...Picture070.MOV , it's goosehonk. Completely normal.

 

damn, thats a good cameraman right there!

 

Welcome to the world of the Z32TT sounds. You might also smell burnt rubber and your view in your rearview mirror is nothing but a cloud of smoke, this is normal also. People behind you hate it. They can't see anything but your smoke. Hehehe

 

Thanks guys... I was a little worried about the noise, I'm glad is nothing. This weekend I went driving on HW 9 in Boulder Creek, California (little one-lane windy road) and I can't believe the handling on this car! Never had a better ride... Fredo.
