I am not a professional, but I have been around karting long enough to see new comers come and go because of stories like this. The same people are going to win at these higher end races if they had one of these so called matched perfect engines your claiming they have (days of thunder movie comes to mind). They have the seat time, they have the experience of setup, and they know how to plain make the whole package work!! A small gain in HP is going to help in racing , but its not going to keep you there week in and week out if your not on YOUR game. So saying you HAVE to pay that much for a matched engine does not hold water in the world of racing. The whole package is consistence. Horsepower is hit and miss for good finishes.
