Hi ukravit; i've noticed from some dyno sheets, that the power output can dip when the secondaries open. I'd be interested in what you discover from opening the secondaries more slowly... maybe a stepper motor.just looking for a more progressive way to open secondaries. Imrc opens fairly quick, Vac opens a little slower. and opening will be controlled by engine not computer. No data on this so I will experiment with it.
this is a fairly interesting thread, I'd like to see how vac secondaries work on a ported 3.0 or a hybrid...
Does the ecu still control the vacuum operated secondaries, or are they set to a something static? If there's no way to tune them, then I think they would be a downgrade.
