Wheel horsepower has no bearing on the E.T. of a car, the E.T. is generated by traction (tire, suspension and weight distribution), gearing (transmission and final gear ratio of the rear end), and torque converter that is all matched to the torque characteristics of the engine (if it's an automatic). Take all of these variables and the weight of the car plus the current weather and you will determine the speed of the car at the end of that quarter mile run.
E.T. will vary dramatically from car to car with the variables stated above along with the state of tune in the chassis and drive train.
In other words, if the same engine was taken out of that car and put into another one that weighs the same, the M.P.H. will be pretty much the same but the E.T. will be different.

I've been down the stocker route multiple times and the converter can make or break a combination, it is not all the motor
The first 8 inch art Car race converte we put behind the hemi stocker we where racing back then slowed that car down.35 ET and over 3 MPH compared to the stock Mopar 11 inch street hemi converter
I know another NHRA world champion that change five converters in testing one weekend at a division race to pick up .03 and .2 MPH
It is the total combination of parts and driver, it is a lot of hard work and parts swapping and testing to make them achieve what they do
