He does make a point. Especially about the stress on the car. which is why when your car is becoming more and more high performance, get another vehicle. I'm picking me up a bike in about a year or so. Also the more and more high performance your car gets, the more and more care you need to show your baby. Always show your car some lover, give her good oil and good gas, she'll love you forever.
Another thing, it is hard to have the "how fast" question. It would be easier saying something like " I want to get X amount of WHP on NA. How might I go about reaching this goal? " You see what I mean?
