This is it, the fourth installment of an incredible cross-country road trip to race Jon Chase at the NHRA Winternationals in Pomona, California. Yeah, you probably already know the outcome of this race because it happened weeks ago and there's plenty of videos from the Hoonigans, Motor Trend, TheCraig909, FourSpeedFilms etc, but this is the tale from my point of view. I'm picking up the road trip to the race as we prepare to leave The Horsepower Connection in Lake Havasu City, Arizona. We finished dyno-testing Blasphemi and although it would not stop leaking water from the cylinder heads into the crankcase, it did put 1,070hp to the tires. To prevent making a motor milkshake during the event we decided to drain the water out of the engine and only run it long enough to race down the track. The new ramp truck, Square Force 1, was running great but only getting about 5.5 mpg and we wanted to know why. Sure, it's loaded down with Blasphemi, my tools, boxes of t-shirts and is pretty much a 14,000 lb brick pushing through the wind, but we still wanted to know how the 454 V8 engine was running. So David Newbern, Mike Cotten and I, along with Steve Darnell and Merlon Johnson from Welderup, decided to install a Holley Wideband O2 sensor and custom gauge to see the air/fuel ratio of the engine in real-time.
