He created a plug that fit directly into the plenum of the intake, in order for it to fit, the chutes had to be eliminated. The rule went into effect for the ARCA Daytona race in 1994. The unrestricted compression ratios enabled the engine builders to create more horsepower. The smaller the volume of each cylinder, the more power that is created when the fuel mixture ignites. The problem was multiple failures and debris from those broken engines on the racetrack.
Engine failures are virtually nonexistent today.
Once again, it looked at ARCA to solve the problem. In 1997, ARCA had gone to a mandatory 300-pound rear spring to help hold the back of the cars up in the air. The more spoiler that catches the air, the more stable the car drives. ARCA changed the minimum to 350 pounds in 1998. This season, the Winston Cup cars will finally be required to use a 345-pound minimum rear spring, slowing the cars down and making it safer and more comfortable for the drivers.
