The Land Speed Record is often framed as a duel between nations (e.g., Britain’s Campbell vs. America’s Breedlove). However, the Southern California Timing Association (SCTA) class system democratizes the quest. Within this ecosystem, Jim Moffat, an unassuming mechanic and fabricator from the Pacific Northwest, carved a niche. His name appears not in the absolute record books (over 600 mph), but in the coveted 200 MPH Club and in specific Classic Category records. This paper explores how Moffat’s philosophy—trading peak power for sustained reliability—allowed him to achieve speeds exceeding 240 mph in a door-slammer Camaro, a vehicle whose basic architecture was never intended for such velocities.
Where other teams laid down multiple passes to scrub the course, Moffat employed a minimalist approach: exactly two passes per meet (one license/practice, one record attempt). This prevented “salt creep” (loose salt accumulating in wheel wells) and kept engine temperatures within a predictable envelope. His crew’s primary tool was not a wrench, but a laser thermometer and a stopwatch . They monitored coolant delta-T (difference between inlet and outlet) in real-time; if it exceeded 15°F over ambient, they aborted the run. jim moffat land speed record

LSR is not about tire grip in the conventional sense; it is about shear strength of the salt crust. Moffat’s tire choice— Goodyear Land Speed Specials —were bias-ply, not radial. Radials generate heat through sidewall flex, which softens the salt substrate. Moffat ran tire pressures at 55-60 psi (far higher than drag racing) to minimize the contact patch’s length , thereby reducing the chance of hydroplaning on brine.
Moffat’s 1991 run of 240.1 mph in D/Classic (305-372 cid) demonstrates engine scaling . He de-stroked his 454 to 366 cid, achieving a higher power-to-displacement ratio (approx. 0.88 hp/cid) while reducing piston speed from 4,500 ft/min to 3,900 ft/min—a 13% reduction in reciprocating friction.
