| FIG I EXISTING GLAND FITTING & INTERCONNECTING PIPE CYL BLK WATER OUTLET PORT 1.6" DIA. GLAND FITTING 1.434" DIA. INTERCONNECTING PIPE 1.25" DIA SCALE 1/1 FIG II SKETCH 3 PROPOSED NEW GLAND FITTING & INTERCONNECTING PIPE CYL BLOCK PORT CHAMFERED ON INSIDE EDGE BY MAKING A SMOOTH ENTRY INTO PIPE THE FLOW WILL BE CONSIDERABLY IMPROVED EVAPORATIVE COOLING IB KESTREL CARB IN VEE FIG I SHOWS THE STANDARD FRONT CYL BLOCK WATER OUTLET GLAND & INTERCONNECTING PIPE UNITS THE CONSTRUCTION OF WHICH GREATLY RESTRICTS THE WATER FLOW THE BORE OF THE INTERCONNECTING PIPE IS .350 SMALLER IN DIA. THAN THE CYL. BLOCK PORT IMPORTANT. THE BORE OF PIPES LEADING FROM THE CYL BLOCK SHOULD BE AS NEAR THE DIA OF THE CYL PORT AS POSSIBLE FIG II SHOWS THE PROPOSED NEW GLAND FITTING & INTERCONNECTING PIPE & AS SUGGESTED METHOD OF IMPROVING THE ENTRY INTO THE PIPE TO OBTAIN THE MAXIMUM WATER FLOW GIB 8-4-32 | ||
