Tuners are still exploring the limits of the horsepower potential of the Mustang’s Coyote 5.0L V8, perhaps none more so than Jon Lund, Jake Long and Ken Bjonnes of Power by the Hour. The threesome have been developing and testing their twin-turbo system for the current Mustang for a little over a year now, and during that time they’ve proven the car’s performance merits with a 9-second quarter mile pass and doing the standing mile at over 200 mph.
Despite their impressive achievements, the trio isn’t quite satisfied and have recently added even more power while experimenting with a prototype of an upcoming high performance Coyote engine block from Ford Racing. The result is an astounding 1,266 horsepower and 1,058 lb-ft torque at the rear wheels, which the company says is the highest output of any street-driven Coyote-powered Mustang.
