Kevin Heap wins with modified Arctic Cat DVX
Kevin Heap
Kevin Heap beating a Yamaha YFZ 450 with his modified Arctic Cat 400 DVX on his way to the win at Chillicothe, IL in 2005.

Gary Heap and his family are longtime customers, and when son Kevin wanted his Arctic Cat ATV modified for drag racing we were eager to work with them. The Heap farm includes a test strip that is heavily used to evaluate performance mods, so we knew we would get valuable feedback on our parts. Kevin chose our Mega Power Performance Pipe and Header, High Flow Aluminum Air box, Edelbrock Carb, Racing Cams and High Compression Piston. The head was extensively ported, and Kevin claims the head mods made a big difference in top end power. The end result is a very lightweight machine that can beat Yamaha YFZ 450ís, which Kevin did at many races. Kevin won several classes at Chillicothe, Knoxville and Aledo Illinois.
