Dave W I just tried the link and it worked.Interesting(not that we have that kind of money)some of those engines are rentals at $50,000 a event that comes with a tuner.They meet up at the event and put it into the car,tune it,and at the end take it back out.Costs for a season is 1.2 million.Talk about buzzing them up to 10,000 RPM and what developments have occurred to allow the kind of results we see today's cars.Lots of heavy name hitters involved.
