I was wondering if anyone has a Blitz bov on a small single like the TSO4 or SP 57. I have noticed that a lot of the big single setups, like T-78, have two Blitz BOVs. Do you think one BOV will be sufficient for a small single on stock fuel? Thanks ahead of time.

From my understanding, the BOV doesnt have anything to do with the amount of horsepower.. then again, it needs to be tuned to the correct amount of air coming out... eg hard springs, soft springs, etc etc..

am I right about this??

well.....if you have more boost than a bov can handle....it will emit some back pressure to the turbo and over time it will cause damage. The blitz bov, when proberly tuned, will make a nice psssssssssst sound. If the bov is too tight...or if it is open all the way and the turbo is too big for it (T-78 for example)...it will make a shuttering pssstttpsstttpssst sound and you can hear the back pressure forced on you turbo.
Anyways......I think the sping that the blitz comes with is the hardest spring.
