Everyone is assuming the option is to go for gold in the power field.... Not everyone wants a 500+KW street driven car.
What if you don't want to go for 450+KW, what if you don't want a single?
What if you want 300kw, subtle, street driven machine?
For some circumstances it just isn't required. Like i have stated many times. Everything is relative. What power goals? Cost restrictions on the entire build? Feel of how it drives? Fitment issues (if going 3L), and even legalities (in some states)
Honestly after all the cars i have been in, anything over about the 350kw mark is just making power "because i can" you seriously can't use it on the street. Anyone that says they do is kidding themselves. I had 320KW and it was already overkill. But don't get me wrong, track car is a completely different ballpark. I'm merely commenting on a street basis.
