so I have a large BOV, on my st165, its a t piece between the turbo and the IC,
I have a vacuum connected to the left side of the throttle housing as suggested.
the BOV vents to the air, but many people do have problems because of the air already being metered by the AFM.
1 - I could connect the exit of the BOV so it goes back into the intake before the turbo? so I would still get the BOV "booosh" and the air is still in a closed circuit?
2 - if the air from the BOV is put back into the intake, surely the extra boost your trying to get rid of is still in the system but your not using it, excessive boost still in the system, or is that ok as long as its travelling the correct route through the turbo and not pushing back through the one way system it.
3 - dumping boost back into the turbo, what happens to it? if your not on the throttle it would effectively create a perpetual motion machine, boost, dump, recirculate, boost, dump, recirculate, until you put your foot down and then more air gets put in the system as well as the recirculating boost, to much air? something breaks.
4 - if Toyota never put one on the car, then what's the problem, Toyota must have expected this car to last 200.000 miles and not 20.000 before things brake, like a turbo. if Toyota knew that excesses of boost was trying to get through a closed system they would do something about it.
5 - at the moment my car is building up boost and when the turbo is about to kick in its dumping and stall/goes lumpy for a second or 2 then goes to normal again. but works fine when im stationary, and revving the engine, although its been a while since I have ran it and I may have rectified it now, will drive it tomorrow. thoughts were I had my BOV set up to let go of the boost to soon, well.... way to soon as its not even started boosting yet. BOV, vacuum, leak, etc....
I have put new spark plugs in and this might rectify it, easiest thing first right?
why would shitty spark plugs affect the dumping of boost, or could it be fuel cut because the spark is weak?
I swear the boost dumped first and then cut. maybe wrong, tomorrow will know more
