Racingbeat 1992 Bonneville crash flying FD3S Mazda RX 7 RX7

In early 1992, Racing Beat started development on another Bonneville Land Speed Record RX-7. Driven by Jim Mederer, this three-rotor, three-turbo engine propelled the RX-7 to a 204 MPH class record at EL Mirage Dry Lake during its initial “shakedown” runs. In August of 1995, Racing Beat set the C/BMS class land speed record of 242 MPH at the Bonneville Salt Flats.

This RX-7 is shown in the paint scheme that was used during 1992 practice runs at El Mirage Dry Lake Bed. This car was used in a Land Speed Record attempt at Bonneville Speedway that abruptly ended when the car became airborne at approximately 230 MPH! The car was repaired and repainted in "black" paint scheme, then successfully set two land speed records.

RACING BEAT prepared this 1993 MAZDA RX-7 in conjunction with MAZDA Corporation for the 44th Annual Bonneville National Speed Trials. The event, held on the Bonneville Salt Flats at Wendover, Utah, USA, was scheduled for the week of August 16th through 22nd, 1992.

RACING BEAT's intention was to eclipse the C/Blown Modified Sports (C/BMS) record of 241.48 miles per hour (388.62 kilometers per hour).The 1993 MAZDA RX-7 utilized a multi-turbocharged three-rotor 13G rotary engine capable of producing in excess of 760 horsepower at 8000 RPM, at a boost level of approximately 14 PSI. Also incorporated in the project was an E.F.I. Engine Management System.
The drive train for the vehicle, a Weismann 5-speed transmission coupled to a custom-made differential, containing a 2:1 rear end ratio, was specifically engineered to handle the engine's extraordinarily high output. The innovative suspension system, completely a RACING BEAT design, had been tailored to meet the high speed demands of the Bonneville Salt Flats.The race car started as a stock 1993 MAZDA RX-7. The floor pan was completely cut away and discarded. The shell was then filled with a tube frame and roll cage, and a new floor pan constructed of carbon fiber was bonded to both the tube frame and the shell, thereby allowing the possibility of improved aerodynamic tuning.

The RACING BEAT 1993 MAZDA RX-7 Bonneville Project represents a considerable degree of joint sponsorship support from MAZDA CORPORATION, GOODYEAR TIRE AND RUBBER CO., NGK SPARKPLUGS, TMC COMPANY, LTD., SIGMA AUTOMOTIVE COMPANY, LTD., NAGAI ELECTRONIC INSTRUMENT COMPANY, LTD., AND SANWA TRADING COMPANY, LTD.The Racing Beat RX-7 is shown in the "Back In Black" paint scheme after an ill-fated record attempt in 1992 when the car went airborne at over 220 MPH! After repairs to the RX-7 were made, Racing Beat returned to the salt flats in 1995. Although it was hoped this car would travel close to 300 MPH, poor weather and salt conditions kept the top speed to a modest 242 MPH. Mazda announced that production of the RX-7 would cease after the 1995 model year, and the RX-7 Land Speed Project came to a close.

Today this car still stands as the WORLD'S FASTEST RX-7!
