This isn't my car but you might find it interesting.

Swift DB-1 Formula Ford. Tested by Road & Track in March 1984.

4 speed transmission geared for 116 mph top speed at power peak of 6500 rpm

Test Weight: 1115 #

Rated HP (1.6 liter ff engine) 114, Rated torque  105 (a little low by
current standards)

Tires: Road Racing slicks

0 - 60 mph: 4.6 seconds (with a 49 mph first and a 71 mph second gear)
(third was a 94 mph gear)

1/4 mile: 12.6 seconds at 110 mph

They didn't do 60 ft times but the 100 ft time was 2.8 seconds.

No reaction time info.

My car at the Pro Solo practice starts "60 ft" times best ever was 1.762 at
Peru in 1999 with EXCELLENT traction. "Normal" is just under 2.0 with tire
spin and a 45 mph first gear, on slicks. 

Note that in 1984 R&T "only" got a skid pad G level of 1.280 which was a
record at the time (and much below what current tires would allow).

The R&T slalom speed was 72.2 . . . another record.

60 - 0 stop: 84 feet

80 - 0: 141 feet

Normal Assumed FF top speed with Road Atlanta gearing: 140 mph in those
days. Don't know what they turn now. 

Remember, these are open wheel cars.
