Mustang Cobra Mammoth Blower Kit - Wild and Woolly
Kenne Bell developed the Mammoth kit in its usual time-intensive fashion of strapping the car to the in-house Dynojet, wiring it to log every imaginable temperature and pressure, locking the ignition timing to reduce variable, and then testing. Such dyno mules may spend up to four months on the roller before coming off for part-throttle driveability tuning.

Four dyno runs of interest from the Mammoth development are presented here. The first is the stone-stock Mustang Cobra; the second is the baseline Mammoth installation where the complete Mammoth kit was installed and run on 91-octane pump gas; the third run documents the Mammoth kit tuned with race gas, 20.5 pounds of boost, and the after-cat unbolted. This is the 704hp peak power run; our 200-rpm-resolution dyno charts didn't capture this peak (maddeningly so, but that's always the way it seems to go). The last test is identical to the third, but with the 3-inch Bassani aft-cat installed. All runs were made on Kenne Bell's Dynojet with SAE correction.
