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.
