There is a "truth" to what they say,but it's taken completely out of context,as other members intuit,to capitalize on disgruntled motorists attempting gas saving mods.At WOT,the intake tract WOULD be closer to atmospheric pressure,so pumping losses would be reduced a fraction( less than an inch of mercury delta-P).BMW's attempt to remove the throttle body and entire intake(save for the air cleaner) tract,including the camshaft and conventional lifters,is a more visionary approach to reducing losses.---------------- I give the big -bore "the big Spanish Archer" as Burt Munro would say.A big thumbs down!
