New to this site. I have owned my current Cheetah since 2007; with high compression upgrade. Have fought high cylinder temps on takeoff forever. I finally found 2 things that completely fixed the problem.
1. I got the carb rebuilt and richened with bigger jets. The folks at D&G supply in Michigan are experts on getting you the right carb setup for HC Cheetahs. This helped keep temps lower.

2. Install a “Candeletti” cowl flap just forward of the cowling cooling exits underneath. They bend down 45 degrees and create a low pressure area that sucks more air out the bottom of the airplane. I fabricated two pieces of aluminum and bolted them on. It makes a HUGE difference. Peak cylinder temps on takeoff came down 30-50 degrees. I have attached a drawing.

With these two mods I can fly my Cheetah here in Florida in the summer and keep my peak temps easily below my personal limit of 450 degrees, usually under 410 or so.

Call me any time if you have questions; 801-918-9722.
