Got a Pulsar Posted January 13, 2013 Share Posted January 13, 2013 I believe the R34 and R33 BOVs are the same and 12psi will be fine.

mad082 Posted January 13, 2013 Share Posted January 13, 2013 the stock bov should be fine for 12psi. you have to remember that it isn't just the spring pressure holding it shut against the pressure in the cooler pipe. it has a boost feed so the pressure on each side of the bov is the same. so while it is just the spring holding the bov shut, it isn't just the spring vs 12psi. it is the spring + 12psi vs 12psi. if you get what i mean, lol.
