The Super Coupe's comes equipped with a 3.8
liter V-6 powerplant that is force-fed with an Eaton Corporation
supercharger. The 8.2 to 1 compression ratio, combined with six computer
controlled sequentially fuel injectors, completes the well rounded
underhood package. While running at a maximum 15,600 rpm's, the supercharger
provides 12 psi of boost and as a resultant it develops 210 bhp at 4000
engine rpm's. The engine develops 315 lb-ft of torque at 2600 rpm. The
supercharged V-6 delivers ample power without much noise but an underdrive
kit and a performance chip are available to boost the horsepower rating to

The 4-speed automatic transmission features a 0.67:1 overdrive ratio
and an electromechanical lockup to eliminate torque-converter slippage on
the supercharged models.
The Thunderbird SC braking system features 4 wheel disc brakes with
ABS. The Thunderbird SC can stop in 140 ft from 60 mph. From a speed of 80
mph, it takes the SC 247 ft. to come to a safe stop.
Up front, the T-Bird rides on a short and long-arm system rather than a
more conventional MacPherson-strut arrangement. This system features
variable-rate coil springs, a 1.2 in. diameter anti-sway bar and
electronically controlled nitrogen-pressurized gas shocks.
suspension is even less conventional for a rear wheel drive domestic sedan.
It's fully independent with a large lower H-arm on which the variable-rate
coil spring rides and there is a smaller U channel upper arm. These arms are
tied together by a cast aluminum knuckle. In addition, there is a 1.1 inch
diameter anti-roll bar and gas-pressurized shocks with electronically
controlled damping. The car's gripping power comes from the big P225/60R-16
Goodyear Eagle GT-II's mounted on 7 inch wide light alloy wheels.
The SC is equipped with an electronic suspension control. You can
definitely feel a difference in the ride when you switch from the soft and
sport (Firm) setting. The ride control system is made by Tokico. A computer
monitors vehicle speed, brake-line pressure, steering angle and
engine-computer acceleration signals to determine the shock valving. There
are two switch settings. These settings are: Auto and Firm. The automatic
setting selects soft shock valving for a smooth, comfortable ride. When
driving conditions require a firm ride, it automatically overrides the soft
valving. The firm position is simply an override that selects the firm
setting in all driving modes.

Do not confuse a turbocharger with a supercharger. They operate in
completely different ways and none of the parts are interchangeable. The
turbocharger and supercharger are serviced by replacement only.
The supercharger is not a bolt-on option. It is part of an integrated
engine system. Many components of the supercharged engine are not
interchangeable with similar parts from a non-supercharged engine.
The supercharger has a self-contained oiling system that does no
require a fluid change for the life of the vehicle unless damage occurs. The
fluid level should be checked at 30,000 mile intervals, or if visual signs
of leakage occur. Checking oil levels can be done by removing an Allen head
plug located at the front of the supercharger. The oil level should be at
the bottom of the fill plug threads when cold. If the level is low, add a
synthetic supercharger fluid that meets or exceeds the Ford specification of
