mine made 171bhp, i don’t have bvh but do have 51mm tb, 1341cc bottom end and cam. My boost pressure is about 10psi and creeps up to 12psi. I’ve always used aldon for rolling road days as its very good. I’ve been twice and made 170 and 171 2 years apart.
Im was looking to put my g40 inlet back on to see if it would help with the power, a friend with a charged vr6 got a bigger inlet from another vr engine and had it dyno’d on the same day and it made a loss of power. He reckons if he was running more boost it would of made more power but the inlet is almost too big internally for the low boost he’s running.
