wait these things actually work, hahaha i bought a couple of these a while back when we used to street race in philly we would strap em on unsuspecting cars and just have a ball laughing...they sound real suprisingly...but no significant value whatsoever...
A BOV is a short, sharp Pssstttt! on release of the throttle (dumping of manifold pressure on over-run). This will not achieve that - this just makes the 'simulated' high pitched whine of a turbine as the engine rev rises. It's bollocks. :smoke:pearl r/t they really sound like bov? if they do i wanna buy 1 put in my moms car scare the **** outa her
