This is making me think that disabling 1/2 of the intake valves would be a stupid idea. It would make the vacuum on the piston much higher and more efficiency would be lost than gained. What we need is a very good breathing engine with an extremely short duration camshaft....like 200/200 degrees seat duration or less, as opposed to the 280/290 or so as is. Peak torque @ <2500. That would rule. Would my engine management system know the difference? Or would the CEL come on, throwing this whole thing into an open loop nightmare?
