The gang over at Late Model Restoration (LMR) is back with another dyno test of a classic Fox-body Mustang. This time the car is a 1986 Ford Mustang SVO that looks fantastic. LMR says that the car is bone stock save an upgraded 190 liter per hour fuel pump and a manual boost controller.
LMR says that the boost controller is set at the factory 15 psi of boost. The 1986 Ford Mustang SVO had a switch from the factory for premium fuel, and the pull is made with that premium switch on. The dyno pull was made with the transmission in fourth gear, the 1:1 ratio for that car.
Ford used a turbocharged 2.3-liter four-cylinder in the iconic SVO Mustang. It was rated for 200 horsepower, and 240 pound-feet of torque says LMR. The result of the dyno pull showed 170.39 horsepower at the wheels with torque of 250 pound-feet at the wheels. The torque rating is interesting since the car was rated at 240 pound-feet of torque from the factory.
The dyno number showing 10 pound-feet higher than the car was rated from the factory at the crank, at the wheels it appears Ford was sandbagging a bit. It’s not mentioned how many miles are on the 1986 Ford Mustang SVO they dynoed, but we assume the car gave up some power over the years. We wonder what the car would have put down when new. In its day, the SVO was the Mustang to have with better performance than the V8 GT cars. Any way you cut it, the legendary SVO has less power than many four-cylinder cars today.
