It seems the 2.0 liter Volvo MPS has one critical difference.
the lack of a diaphram for the adjuster screw. The result, as far as I can tell, is the full load setting will result in a bit leaner running setup if left alone. Basically what I can figure is the adjuster diaphram is compensating for atmospheric conditions only for the aircooled full load circuit and for nothing else. The screw moves and thus allows more movement of the inner diaphrams that really control the results. So, if used, I think (and I will test this) that the car could be made to run a bit richer in the part load circuit to ensure the proper settings for WOT or full load. If I am correct, its a far more tunable setup and it has no diaphram that will fail. So, has anyone tried one? With good/bad results? Rich |
