Information Blow Off Valves?
A blowoff valve goes onto your intake or the piping from your turbocharger to make sure that you dont run to much pressure they are adjustable to whatever pressure you desire. Usually people running a positive displacement blower or a turbochargers run them. That being said I'm sure that you could put one on your car but without a power adder it would never blow off. Except in the case of a intake manifold overpressure such as a backfire.
