Hey guys, my friend has recently purchased a car that has a pt-88 with a 6 speed, 331ci and we have been trying to get the co2 boost control to work properly and it just doesn't seen to co-operate. On gate spring (red) it makes 4-5psi smoothly in all gears. We apply 12psi dome pressure and that's where things get Wierd. It holds that 12psi pressure until the wastegate moves at which point it's as if there is a leak bleeding the dome pressure off. The boost does climb but as soon as that dome pressure bleeds off, it's going down (as one would expect it to) ... It should be said that this is the second gate we have tried (first was smaller and older so we upgraded) and its following the same characteristics. On the run I'll post up, I cheated and commanded 100% duty cycle on the boost solenoid and used the co2 regulator to achieve 14psi dome pressure to rule out the solenoid, but it still bleeds down... any thoughts?? usually in my own car my dome psi actually goes up a little as the gate opens (due to pressure difference moving the diaphragm up like a piston as the gate opens.. It certainly never drops? I don't think it takes up much volume to keep 12-14psi dome psi ?...
