I just can'tseem to understand why the various horsepower calculators that have been posted always give me about 50 to 70 more horsepower at the rear wheel than the actual dyno results. Maybe I should be happy with what I've got and not burn up anymore brain cells trying to figure out where that mythical 50 to 70 horsepower is hiding at.
