G-Games
1994 Toyota Supra
Big Power, Big Grip, Big Boom

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
useable 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.
1994 Toyota Supra
Balancing Grip, Power and Speed
By: Josh Jacquot
Representing Turbo magazine, Nils Leufven's 1994 Toyota
Supra showed up at the G-Games ready for battle. With a
claimed 636 wheel hp from its HKS single-turbo conversion,
it represents a formula known to be successful for huge
power number on many late-model Supras.
What we didn't expect from Leufven's car were the amazing
skidpad and slalom numbers the machine produced riding on
Tein coil-overs.
On the skidpad, Leufven's car generated a brain-punishing
1.009g. That's an amazing number for any car, but
considering the weight (3,445 lb. Stock), and size of the
Supra, we never expected such an awesome display. Consider
that the g-Force is a street tire and the data is even more
striking. This performance was good for third place behind
the RX-7 and Beetle racecar.
Through the slalom, the Supra was impressive. It blasted
through at 71.7 mph in a dead heat with the 914 Porsche, and
only .7 mph behind the RX-7 - good enough for a third-place
tie. But the best bit about the Supra's slalom performance
was its high-speed, power-on exit. Every quick run through
the cones ended with a tire-blazing powerslide through the
last gate. Interesting driving, to say the least.
The car's character from behind the wheel is also worth
noting. We expect most cars capable of these numbers in
instrumented testing to be compromised in normal driving.
However, even with limited time behind the wheel of
Leufven's Supra, it's clear this isn't the case. Uneven
roadway and bumps that could've been kidney-splitting
disasters were absorbed with supple damping and adequate
wheel travel.
On the road course, with Chris James at the wheel, the
silver Supra didn't fare as well, lapping the Streets of
Willow in 1:08.30 - more than a second slower than the black
Supra. The car's sever turbo lag made exiting corners
cleanly more than difficult.
Even with its mid-pack lap time, the Supra managed an
overall finish of third place - and our over. Beating the
Supra's overall score were the national championship
autocross-winning Mazda RX-7 and what amounted to a
tube-frame racecar. When all is said and done, this silver
bullet is a well-rounded combination.
