When MM&FF rolled into Blow-By Racing, the weather was less than conducive to making power. The only upside to this was that there were only slight changes over the course of the day. When we started, the temperature around the dyno was in the mid-80s with about 50 percent humidity. As the day went on, the largest increase in temperature was less than 5 degrees, with an equal decrease in humidity. Our baseline gave us a peak number of 269.63 rwhp at 5,300 rpm with torque peaking at 296.19 lb-ft at 4,400 rpm. After steady gains all day, our series of bolt-ons resulted in a total of 309.11 rwhp at 5,500 rpm with torque peaking at 324.36 at 4,400 rpm.
