It really depends on the turbo and how much boost your running rather than the actual blow off valve design. Get your girlfriend a nice small T25 and a RFL, and her panties will be wet in no time, Fast and Furious Style

But DSM valves are a great valve

Here is a pic of her a IHI T25 turbo and the whole kit its a bad pic but you get the idea...........
