Manifold / Riser Temperatures

Post by Briank117 »

Hey gang,

Wanted to see what is an acceptable temperature range for 318 manifolds and risers to be. Temp gauges works fine—new impellers and 140* thermostats on both motors. Exhaust flow is fine. Just shooting everything with an infrared gun at idle after 5+minutes. Risers seems to be hovering around 150, manifolds are around 110. And I have the classic—port is a tad warmer than starboard, on both motors.


…..Fridge is at 36* :D
