If you are not tracking the car I see no advantage of making the car faster. Unless you are a Honda owner that prides 0-60 times over track times. Remember you may get more horse but you will NEVER outcorner a Ferrari in a Jag just not going to happen. And who wants a car that is only fast in a straight line. Only dragracers. And if thats what all this fuss is about then why are there no drag racing Jags?
