just so you dont read this whole thing and get pissed, you dont gain any hp from this so if your looking for power dont look here. i had been noticing a increase in posts on bovs so it made me think about mine. lots of people call the mopar bov a noise maker and i guess ill admit it pretty much is, but from that i realized this thing has potential. then i thought about how all it is is large amounts of air forced through the holes. if i could harness that air and channel it through various things i could have alot of fun, so i went and scrounged through my house and came up with a party noise maker, a whistle(cylindrical metal), and a hunting call. i think you know where i am going with this now, im not sure what size tube it is but i had some left over tube from a wolo air horn that fit perfectly in the hole. then i simply attached the other end to whatever sound i wanted to make. the whistle sounds alot like greddy, the noise maker sounds like a cop siren on steroids. my favorite is the hunting call, its actually a predator call which means it sounds like a dieing animal. every time i let off the gas it sounds like demons are coming out of my car, it is excellent. so i say to you, in all the seriousness of our racing do not forget to have fun with it, you have no idea how hard we laughed the first time the dieing deer wailed as i pulled a hard shift from second to third. if your bored with you boring old bov, try it u wont regret it.
