whats up everybody I am new to this site, sorry for the lame question but i wanted to know. I Was driving yesterday and a civic pulled up next to me wanting to race, when he hit his gas his car made a air sound like a air compresor was firing, What was the sound? and how much does it cost, i know that it must have gave him a preformance gain because he smoked my azz should have pulled out my bike. Thanks for the replies.

 

thats a blow off valve from a Turbocharger.......the BOV itself is like 200 bucks but the turbo u need for it to work is over 1000$

 

Or possible a cold air intake which a good one should cost around $200.

 

It's good to hear these kinda stories from the people that got beat.
And my hats off to camilion4, because he took it like a man and never said anything negative against Hondas.
