| HP = torque*RPM/5252. NA motor torque and displacement are directly related. So the only way a NA car can make more HP without increasing displacement is for it make max or more torque higher up on the rev range. So if a 3L VG motor can make 200 Ft/Lbs of torque, then it would only have to make that torque at ~13000 RPM. Or maybe he increased the displacement. At stock redline, he would only have to make 375 Ft/Lbs of torque or roughly almost double the displacement.. I say its believeable. (yeah right, keep dreaming NA guys) Ken 91TT
