1994 Toyota Supra

Final Score: N/A pts.Ken Henderson's 1994 Supra Turbo, representing Turbo magazine, was one of the most prepared cars at the G-Games. With 690 hp at the wheels, Tein coil-overs at all four corners, chassis braces from TRD and Cusco as well as huge Brembo brakes, this car is an obvious choice for quick lap times.

It wasn't Henderson's day, however. We tested for skidpad numbers on the monster-power Supra, but a random power steering pump failure on the road course put it out of the competition before the car's driver, Chris James, could finish all his laps.

The power steering overflow tank valve stuck closed, causing the rest of the system to self-destruct. Henderson and the crew from SP Engineering, who were on hand to service both Supras in the contest, made last-minute efforts to repair the failure by bypassing the pump. The resulting high steering effort made the car practically undriveable on the road course. Still, the Supra turned a 1:07.1 laptime-the second quickest of the day.

On the skidpad, however, Henderson's supercar couldn't match the top three, which pulled more than one g laterally. In this contest, it placed mid- pack in sixth place with a still-impressive .948g performance.

Unfortunately, because of the broken power steering, we were unable to test the car's slalom speed, which put the black beast out of the running.

This was disappointing. With its massive power and usable torque curve, the Supra may have challenged the RX-7 for the overall win if it wasn't bitten by a freak mechanical gremlin. We'll never know for sure. What we do know is that Henderson's Supra is one of the most thoroughly modified, well-executed examples we've seen in some time. -Josh Jacquot.
