Blow off valve for JTD
I start new thread just after some tests, which I made on the road. My GT equipped with GTB2056 makes me worry. It spools nice in constant gear, but when selecting gears, surge is too high and turbo spools worse, than original. Its delay is too long to reach 3 Bar. Once I brake turbo rotation it takes a long time to get full pull (about one second). I am thinking about blow off valve to leave turbo in high rotation. I found some kits for diesel. It´s electronic controlled, not overboost controlled. Input is gas pedal positioner, output is solenoid, connected to blow off and vacuum. Nice tssssssssssss sound is fine, but I want it for shorter spool. I´ll be glad for your point of view. Does anybody have some experience with diesel blow-off? Do you think, could it help a little? I´d like to have immediate reaction after gear selection.
