New car(just finished my B&B), new engine (351W, mild cam, alum heads, etc), runs 200 to 205 or so on the highway at 90 degree ambient. A little cooler in the 75 degree evenings. Stop at a few lights and the temp goes over 225.. Scary. Get moving and it comes back down but not fast enough for me. Have water wetter in it. I have a 16 inch Summit fan that is rated at 2,100 cfm, puller. Heavy wire so current to motor is good. The fan is not shrouded and I am improving the "ducting" in the front end to force more air through the radiator. (That would help at speed but not at 6 stop lights in a small town all timed to hold a Cobra up.) It is fall now and somewhat driveable so it won't be driveable in the hot Oklahoma summer. I've been looking for a higher CFM 16 inch fan but noticed some 15 inch fans that move close to 2,800 CFM. Would the higher velocity 15 inch fan be more effective than the lower 16 inch one. I know cooling one of these things down is as much an art as a science but it can be done. I am hoping to short cut some pain and benefit from your experiences. Thanks for any advice.
