The Race
On March 13, 2010, in Gainesville, Fla., Kalitta driver David Grubnic set a top speed record on the 1000-foot track. Here’s a breakdown.
0.50 Sec
10.27 ft — 73.89 mph
The motor screams at its 8300 rpm redline, and the tires buckle under the load of getting the 2300-pound dragster moving.
1.00 Sec
51.94 ft — 113.82 mph
To reduce power and the acceleration of the driveshaft and tires, the ignition advance is retarded from 56 degrees to 27—a strategy to keep the tires gripping the track surface instead of spinning.
1.50 Sec
125.09 — 162.45 mph
The ignition timing is advanced back to the maximum value. The clutch’s throw-out bearing has moved through three of its five stages, increasing the pressure on the discs.
2.00 Sec
231.91 ft — 213.09 mph
The fuel flow ramps to 95 gallons per minute. Aerodynamics increase tire traction so the throw-out bearing tightens its grip. The engine slightly bogs to 7200 rpm.
2.50 Sec
379.86 ft — 248.50 mph
In the time required to take a sip of coffee, Grubnic’s car reaches 248 mph. Some of the clutch plates begin welding together, pulling the engine to its lowest rpm, 6500.
3.00 Sec
566.16 ft — 271.62 mph
Thanks to 5000 pounds of aero downforce, the tires have incredible traction, but wind resistance slows acceleration from the maximum 5 g’s to about 4.
3.50 Sec
783.62 ft — 293.41 mph
Late in the run, many spark plugs have burned away, so the engine is dieseling, and some cylinders simply don’t fire. “This is the engine’s toughest zone,” Oberhofer says.
3.83 Sec
1000 ft — 321.58 mph
The mechanical abuse finally ends as the dragster clears nearly 500 feet per second. Next, the driver pulls the chute and the crew then feverishly prepares for the next run.
