Power Plant:

Ford Super Coupe Engine3.8 liter SC underhood view 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 255 bhp.

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.

Braking System:
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.

Suspension System:
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.

The rear 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.

Quarter Mile times for “Box Stock” Thunderbird SC ‘s:
• With Automatic Transmission: They run between 15.7 to 16.0 seconds at around 86-88 mph.
• With Manual Transmission: They run between 15.4 to 15.7 seconds at around 88-90 mph.

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 ESE-M99C115-A.

Winterizing Your Super Coupe:

If you live in the northern region of the U.S. like I do, around the 1st week of November the weather get colder and that means that the first snowfall of the year is just around the corner.

Over the past 25 years I’ve compiled a lot of information about what to do before you store a car for the winter. Some of these ideas might be helpful in preparing your favorite vehicle(s) for a well deserved rest. (Click Here)
