according to dyno testing the US 2.5 motor has more than the specified 250 ft./lbs.
on most dyno's to the wheels...the 2.5 motor puts out 193-203hp or around 250hp at the crank. (you loose about 25% through the drivetrain.
as for torque we are putting close to 220 ft./lbs. which would suggest actually our torque spec is closer to 275 or 280ft/lbs., not 250. Bigger motor equals more torque.
The 2.5 car (stock) 0-60 ranges from 5.6 (Road and Track) to 5.8 (Subaru). These tenths fall off as you add better tires, tighter suspensions, and engine re-tuning. Guys with stage 2 cars are running 4.7 0-60.
