[QUOTE="Kansas Bad Man, post: 51184, member: 778"] A garden hose with a adjustable nozzle can best show what is taking place and why the relief of the liner edge is helpful for intake performance. When the garden hose nozzle is first turned on it has a fan/ cone appearance . When the intake first starts to open there are two pressures that come into play one positive and one negative, the positive is the 14.2 atmospheric pressure( sea level ) filling the void or a absence of pressure caused by the piston in its downward motion. The negative pressure is being formed by a properly tuned exhaust (negative meaning less then atmospheric) . The relief of the liner prevents a unwanted deflector of the fan/cone. Max excuse the sp [/QUOTE]
