Horsepower Per Pound
Our Coyote started with a Ford F-150 block, a slight overbore pushing displacement out to 304 ci, stock cylinder heads, and some cams from COMP for this DOHC setup, all combining to make 510 horsepower at a weight of 430 pounds(with flywheel). After a little number crunching the lightweight of the bunch comes out to 1.186 horsepower per pound with the flywheel, and 1.24 without.
Getting the last of our naturally aspirated air pumps out of the way first, the Motown II comes in at 433 ci and made 682 horsepower. With a weight of 475 pounds, this puts our hybrid platform at 1.43 horsepower per pound.
Tipping the scales at 589 pounds, the Whipple forces an additional 22 psi though the manifold to make an outstanding 1,079 horsepower, pushing the ratio up to an impressive 1.829 horsepower per pound. We also want to add that we really have no idea what peak torque is for this LSX, the dyno literally couldn’t handle the power it was making below 4,000 rpm.
