I remember "Caddy Hack" - just like Car Craft.  If Hot Rod was a surgeon working in a clean room, Car Craft would be a guy with a sawsall and a dust mask, operating in a gravel driveway. 

Note that the only real "relation" you have is power to speed in MPH.  You can pretty well figure or use the Moroso slide/wish rule to figure power from weight and speed.  Vice-versa too.  More MPH at the same weight means more power, without regard to ET performance.  ET, not so much.  It's a guess and very much an optimum figure.  At the track last night, a Camaro runs 7.85 @ 91.  91 MPH is more like 7.40s.  Car has a terrible 60' and 330 time but the power is there.  Converter, tire, gear, driver, etc.  Our Mustang runs 94 MPH, and usually ETs at 7.20 or so.  I see lots of turbo cars testing - they can't leave worth a damn but post big MPH numbers in the 1/8 against a ridiculously high ET.
