You mean to tell me that a certain driveline will take 175 more HP to drive simply because the engine makes more HP? It just doesn't make sense. Seems to me the driveline will rob "X" amount of HP regardless of how much power the engine makes.

Yep, in the world of real life physics driveline loses will be relatively constant. Sure ... if you are sending twice as much HP through the driveline there may be an extra few HP in loses just because of greater friction loses under higher loads, but is it a straight percentage ... not even close.
With an engine of 350 crankshaft HP .... get 300+ at the rear wheels... I wouldn't be that disappointed. Either you are in the HP race or you are not, if you are building a street engine, throttle response and drivability mean way more than 30 hp on a dyno.
