This is copied from a website that does coating locally.
Exhaust Header Radiated Radiated Temp Gas Surface Heat Heat Drop Temp Temp (uncoated) (coated) 1330 810 170 60 110 1340 810 170 60 110 1350 820 180 70 110 1380 830 180 70 110 1410 840 180 70 110 1420 840 180 70 110 1440 860 190 70 120 1510 890 190 70 120 1530 930 200 80 120 Degree (F) It has been determined that engine efficiency improves by 1% for every 10° degree drop in under-hood temperature. If we were to use the above data, we could reasonably assume that we would obtain a 50 horsepower increase on a 500 horsepower engine. --------------------- I drop mine off today.... $200+tax.. I wanted satin black. There's no difference in performance but the owner of the store did mentioned that it's easier to clean up the silver chrome if you ever drop oil or fluid on it than satin black. So silver chrome it is. Life warranty on coating. |
