has it just started doing it? i had a car in the workshop with exactly the same problem, bov was the cause. if you get rid of or block the external it will test it

nah it was doing it at the brock cruise.....Hayden was telling me about it. and convert ROTFL at your comment.......hehehe

good on ya for giving it a go looks the goods

quite like the look of the black rocker cover, have you thought of painting the plenum that colour too? might look good

with an airflow meter you have to have a plumb back BOV.....

Damn i thought dosing was an external going off not a bov.

Give it a compression test aswell, bent valves can cause a similar issue when on/off boost between gear changes

its when you plum back the boost that comes out of the bov(that makes the noiseback into the intake pipe.reusing the boost if you like

the airflow meter decides the amount of fuel the engine wants (via the ecu of course) and when you have a normal BOV, it sees the motor using air when backing off due to the air being vented, so the ecu adds fuel when the motor doesnt need much at all. get a plumb back BOV or piss it off, simple.

fark i need a turbz instead of a na ..

There was one here at 4s and rotarys....in the $500 challenge where u had to produce as much power as u could for $500....there was a VL in it with a NA RB30 with a t3\t4 splapped straight onto it hahaha running rediculous boost dont know what else they did but they got 265rwk out of it and they won the challenge....i didnt see it I was just told by everyone.
