Thanks for posting that. Jmho, but overall it appears like good improvements. Easier to mfg also, kind of similar to how Delphi flat tappets are made in that the body and valving body start out as separate parts so that the valve body machining is more precise. I like cartridge setup and the longer valve body, not sure if the smaller diameter of the plunger will act better for running a lot of spring pressure. It should react faster on start up like was indicated, but I don’t know of many that complain about noise at start up, don’t think start up is what kills them, failures are likely more from the noise issues that occur from inconsistent bleed rates. That usually shows up after the engine is heat soaked and operating. If they get the bleed rates narrowed down it should be a big improvement, that longer plunger might help a lot just in itself.
