Cool motor shot fire. The Wild Thang engine is manufactured by Prolong and the sound decibel is quite high! Don't forget to turn it up! The temperature is quite high. you don't want to be near him. Because it's so noisy and hot! This is a video from the Rev it Up Car Show. Only one fix, the Wild Thang, was built by Extreme Automotive of Corona, Ca. and it is supported by Prolong.
