The NOS test subject was a bone-stock '05 Mustang GT with a five-speed transmission. In initial tests on a Dynojet dyno, the naturally aspirated 4.6 spun the wheels with a good baseline of 287 hp and 305 lb-ft of torque. Upon completing the installation and with the "big" 75hp pills (36N/30F) in the nozzle, however, the NOS nitrous charge livened up the stock Three-Valve with a power gain that maxed at a stout 344 hp and 415 lb-ft of torque at the back tires-not too shabby. You can clearly see the real fun begins when the nitrous clicks on at 3,200.
