how dose he get that "spppttt" sounds everytime he gives it gas. i dident think that was a turbo..or is it?

thanks

 

it could just be an intake whistle, every aftermarket intake i've ever heard has had some sort of whistle to it. It could be a turbo though, you can hear turbos spool when you really hit the gas, if you heard a "pssssh" between shifts, thats the blow off valve, in which case that would confirm if its a turbocharged car or not.

 

If I got a turbo I probably would not get a blow off valve, or if it's required I wouldn't have it set to be noticeable. All I want to hear is the turbo spooling, not pressure being released.

 

^ Factory turboed cars have bov's... what does that tell you?

But the factory bov's are really quiet, so if you wanted a stealthy one, you could get a bov from a factory-turbo car.

to the op: I'm pretty sure flip is right... it's probably an intake whistle. I know my car almost sounds supercharged when it's cold out because of the intake I have.

 

ha, ok thanks guys. i just thought is sounded kinda cool..lol

 

i love the sound of a BOV!!! and that swoooshhh sound intakes make

 

Some factory turbo cars have a Diverter Valve. Diverter valves are just like a BOV except the recirculate the air instead of blowing it out to the atmosphere. If you are looking to be a sleeper use a DV.

 

really?, dident know that, its pretty cool

 

Turbo spools when you put the throttle down
BOV blows off when you let go of the throttle
They do not overlap each other.

 

you could always use a diesel turbo like a cummins i can't remember the word for it but they don't need a bov cuz they relieve pressure elsewhere so you could be stealthy that way lol
