I personally DONT believe that Dynapack measures HP at Wheels. Everyone says Dynapacks numbers are inflated a bit becuase the 268 # they came out with is exaclty what HONDA advertise the Accord at and that is at the Crank.The 240 at Wheels measured by Dynojet is more accurate, becuase the car was put on a roller and thus there is loss of crank from to wheels.I never advertised that my car makes more power than it does and that it easts evos for breakfast
