i know the issue has been beaten to death but i'll join the "there's nothing wrong with having a blow off valve" guys. i have a turbosmart dual port on my t-type, i forget the measurement. it is really nicely machined and works great. the extra volume of the front mount and the longer piping holds a lot of air, plain and simple. i was having issues with part throttle/low boost situations on the highway. it was annoying, and the bov (i hate using ricer abbreviations) made driveability much better, and i didn't care for the constant turkey gobble sound of the stalling compressor. am i going to mount a huge megaphone to the discharge on it to amplify the ricey goodness? absolutely not! i spend my leisure time wrenching and driving my toys, not criticizing strangers on the internet. to each his own!
