i started noticing this a couple days ago. Whenever I press on the gas theres a "pssshh" sound going on. Has anybody noticed this in there tc? you have to drive with your windows down and no radio. try doing this in a secluded area and listen carefully whenever you step on the gas.

 

Well when a car starts they make a sound and when you press the gas you'll hear what you have just heard.


The Engine...

 

Mine is like that. I kinda of like it.

 

engines dont make a "psssh" sound. Ive driven many cars and this is the first making this type of sound. other than my friends fixed up eclipse making a loud "psssh" sound, the tc makes a more subtle one that you really have to listen for.

 

it's the stock semi-cold air intake, they made it have a sort of aftermarket intake hiss, it's completely normal and other people will envy you for having it.

actually no. its the intake manifold. ive seen this on a thread somewhere else. since the intake manifold is made of plastic it makes that sound. kinda sounds like a turbo winding up. or when you shift gears and hit the gas you hear it as the air enters the intake

 

My 85 supra makes the exact same noise, it did not surprise me when i heard it for the first time.

 

OMG not again!!!!

 

my bad... i just didnt know what to type in the search since i didnt know where it was coming from.
