    Something is not right. The horsepower and torque should ALWAYS cross at 5,252 no matter what. Torque can be measured, but Horsepower is calculated with Torque and RPM. The formula for Horsepower is torque X RPM/5252. Not really understanding what was done, but it seems the numbers are skewed.

    edit: the second graph looks correct.

    An engine is an engine no matter the size.... I think Dr. Seuss said that... or maybe it was Big Weld....

    I argued this with some experienced guys... technically correct but it doesn't always show up exactly on the dyno sheet that way. Strange but true.
    All Grand Prix, all the time. 69 Model J, 99 GT & GTP coupes. All junk, haha.
