my brother has a 92 explorer 4dr 4x4 with a 5" lift kit and 34" tires and he has a kkm intake, 75mm maf, 66mm bbk tb, tb spacer, superchip, and flowmaster exhaust and he has 3.73 l/s gears and 90,000mile , he was wondering what you guys think his 0-60 and 1/4 mile time and horsepower at the wheels would be?,, hes only 15 so he cant drive it and his explorer doesnt even have insurance on it so we cant really take it to the drag strip and test it .....so what do you guys think it would be?
