Ensure your timing and fuel mixtures are correct. Lean conditions and incorrect timing can aggravate coolant temps.

What Dave said is spot on. It is important to make sure ALL of the air flow goes through the rad.
Most engine builders set the timing on the engine very lazy. They do this to prevent the engine from detonating. You need to set your timing to come in quick and aggressive, yet still not detonate. With the timing retarded your engine will run hot and sluggish. This is a balancing act and you will need to drive the car and tune it. |
