Despite,
what I said was based on facts, potentials of a car is based on gearing, hp/tq based on rpm of the motor etc. One motor making the same amount of power will do something different than a different car with similar numbers due to the above. In all honesty, this is a fact.
The dyno graph you posted, that car makes more power down low than the one in the attached file ( although the attached dyno is a little rough to read due to size and quality )
So, the hp + track numbers are similar anyways, do you expect them to be 100% accurate and pin point? Its not as if the two cars are seperated by 10mph in the 1/4 mile, more like 2 (or so) which can be caused my many factors. Which this supports my explaination.

car is lighter and his trap was higher add that with the better gearing and drag C.E. it all adds up to a high degree of likely hood that a 9.0 1/8th is gonna = a 13.9** or better 1/4
