 What you're talking about, Joe, under full load, that took 10 horsepower to turn a big old A6 compressor. So, yes, back in the 50s, 60s, 70s, we had very big, cumbersome, bulky systems that ran real big compressors. The compressor Joe's referring to is the best A6 compressor ever built, bar none, forever. They used that compressor. General Motors put it on almost all their cars.
