focus vs 156

wot would win in a race, flat out, and a circuit race?

either :
focus 1.8 zetec, with peco exhaust system and k&n induction kit

-OR-

an Alfa romeo 156 T-spark, with power flow induction kit

in a:
flat out straight line, drag race
-AND-
a bendy roaded circuit race

The Focus and the T-spark are very close but after about 70 mph the T-spark will start pulling on the Focus (less than a 1/4 mile) and as for circuit the T-spark would pull on the straights and just keep pulling every time it got on a straight since they both have very close accelleration.

As for the exhaust and intake mod i dont know im speaking from a stock perspective
