For the last decade, a huge talking point among NASCAR, drivers, fans, media, and everyone in between is how much horsepower these cars compete with. At the peak, there were 900 horsepower monsters that raced well and sounded mean. There were a few years with 750 horsepower and then the dark times of 550. At the moment we are at 670 and when asked repeatedly about it NASCAR President Steve Phelps has been very noncommittal on adding power to the cars. I as well as many fans are wondering why is NASCAR still NOT adding horsepower?!
