the only other point is,

if you compare the two cars, and say both have been modded to say stage 3 greens,

the three door will still have a very small intercooler by comparasion, and the 500 will have the addvantage of the spliters and better air flow though the front bumper and the also have more downforce with the two rear spoilers,

so better cooling

better downforce

holds power high up rev range

bigger ports as standard compared to the three door,

un stressed at this level of tune,
