i drilled the main body into the pv cavity and use turbine back pressure to open up the pv. works like a charm. so much so that i went from a lean condition to rich without changing anything but the reference i used.
I did a similar thing but used the channel used for vac advance and extended it to behind the pv. blocked the hole in body that goes down to throttle plate. took signal from turbo housing. when I went to the dyno he said the signal should come from the manifold.:banghead: basically part of what the crutch mod consists of. what I did is what the dyno guy said to do. it seemed to work after a lot of f#@king around. the dyno guy was a **** useless tuner.
despite him telling me otherwise when I booked the session it soon became obvious that he didn't have a clue tuning a turbo V8.
once my rebuild is done car will go on trailer and head north four hours drive to a reputable tuner.
on the brpv thing, what really does work. seen so many different methods on the net.
no I am not super competitive. I just love to race and have fun doing it. winning is a bonus though.
