I've been lusting after an LS brand XR4145 with fel for some time now. Even dropped by the dealer yesterday with my wife, just to get the feel of things so to speak. She's on board, so I'm thinking it's a done deal if I can just convince myself to turn loose of the cash.

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
