Remember the Suzuki Kizashi Bonneville Special we told you about a few weeks ago that’s developed by Suzuki and Road&Track magazine to break the 200 mph barrier? We even brought to you all making of videos of the car as it was in the works. Now though it’s finished, and as you see here it successfully hit 203 mph or roughly 326 km/h in the Record-Qualifying Run. With magazine reporter Sam Mitani at the wheel, the car achieves 203.720 mph.
Conditions for the Kizashi’s record-setting Bonneville run were exactly as the build team, Advanced Product Engineering’s Richard Holdener, Tom Habrzyk and Scott Bailey, expected. With temperatures topping 100 degrees, the Kizashi was running at a density altitude on the flats of 6,303 feet. After passing inspection, the 2010 Kizashi provided Mitani, Road & Track’s international editor, a perfect platform for qualifying with the Southern California Timing Association (SCTA), the sanctioning club for all Bonneville records. The 203.720 mph record was achieved by calculating the average of a two-way pass at 8:40 a.m. MT on August 18, 2010.
2010 Suzuki Kizashi Bonneville Special
Beginning with interior safety and instrument modifications, the Suzuki Kizashi Bonneville Special underwent additional refinements to make it salt-ready. Once the work was completed, the team installed the SCTA-approved roll cage, an aluminum bulkhead in the rear, racing seat, seat harnesses and window net. Next, it was time to take a look under the hood. The motor was disassembled to confirm the stock measurements, while the cylinder head was flowed and ported. The Kizashi Bonneville racer benefits from a new intake manifold, a tuned ‘long tube’ header and forged rods and pistons for high rpm endurance.
With up to 16 pounds of boost from a Turbonetics turbocharger, the Kizashi’s increased horsepower required air-to-water intercooling (and snow water/methanol injection) – while its increased output demands a new ACT clutch and pressure plate. A scattershield is added, the oil pan is welded for a new drain fitting and a new 3.5-inch exhaust is fabricated aft of the turbocharger. Additional protection for the high-boost, high-rpm turbo motor is provided by full synthetic 5W-20 racing oil from Lucas Oil.
The Kizashi platform – and its Nurburgring heritage – is morphed into a salt-specific recipe with new coilovers, steel wheels seam welded, and speed-specific 15×7-inch Goodyear Front Runner® rubber. An air dam keeps the Kizashi’s nose planted, window straps and hood pins ensure the hood and glass stay in place, and a parachute can bring the high speed show to a controlled and shortened stop. Finally, a dual fire system provides the extra assurance so important for Mitani, with more than 500 boosted horses but only a few feet in front of his high-speed capsule.
