I'm dabbling in the powder coating world during my build and wanted to do my intake after media blasting it. Then I thought, crap, darn thing probably gets almost as hot as the exhaust seeing as the are right next to one another so I'll need to use a high temp powder. I found the color I wanted but it was only good to 1000 degrees. I searched and the only reference to exhaust temps that high were in relation to a turbo diesel. Hmmm so how hot do they get? Well, since no one seemed to know, I, being a gadget freak, bought a tool I could REALLY use! I got a Craftsman Infrared temp hand held temp gun At our club meeting Sunday I measured a 2F engine with headers. I measured at two places, one right where they exit the head and another about 8 inches down. They were within 20 degrees of each other so I 'm only going to post the head readings. These were at idle after a 5 minute warm up on an already warm engine. Cylinder 1: 480 Cylinder 2: 580 Cylinder 3: 563 Cylinder 4: 612 Cylinder 5: 735 Cylinder 6: 605 The highest reading I ever got was 800 degrees measured on cylinder 5 with RPM held at 1500 for about 20 seconds. So has anyone else measured a temp on an exhaust manifold or header higher than 1000? Note: The fan was cooling down the headers quite well as can be seen be the low reading on one.
