JET-HOT Advantages


The chart to the right provides a comparison between JET-HOT and alternative methods for retarding rust. Quoting Car Craft (August 2002): “Anyone who still runs painted headers is a flake!” The chart shows why. At the same time, some producers of “high-tech” coatings actually promote 1,000 hour survival in this salt-spray test as a benefit. In startling contrast, JET-HOT Sterling™ withstands the same salt attack for over 5,000 hours. The testers called it quits before Sterling caved in.


Because of its low emissivity and insulating effect, JET-HOT Sterling™ creates a thermal barrier to protect headers - inside and out - while reducing heat transfer into the engine compartment. But the good news goes beyond protecting headers from thermal fatigue. Plugs, wires, fan motors, water pumps and other heat-sensitive parts get a break, too, in a cooler environment. Plus, power normally increases and safety for racers improves with lower temperatures.

The graph shown to the right, developed independently by a major US automobile manufacturer, shows just how effectively JET-HOT Sterling™ beats heat. The company's engineering team was astounded by temperature reductions exceeding 300°F when JET-HOT Sterling™ was applied to standard exhaust components. Car Craft also took a cool breath, after measuring temperature reductions of over 60% on header surfaces following the application of JET-HOT.

The test results shown are based on the performance of JET-HOT Sterling™.

Other JET-HOT® Coatings, formulated for aerospace, marine and higher temperature applications exceeding 1,300°F, may have different characteristics. Please check with a Technical Representative for additional information.

More Power

Horsepower gains depend on many variables, including engine size, type and setup; cooling system performance; ambient temperatures; and other factors.

Nevertheless, JET-HOT Sterling™ will normally boost power when applied to headers for two reasons. First, the coating promotes denser, more potent fuel/air charges by insulating the engine bay from exhaust heat. At the same time, it accelerates the pulsed-vacuum effect on “tuned” headers, resulting in more effective scavenging of cylinders. The increased velocity of exhaust gases produced by higher exit inertia not only clears each cylinder more quickly; it also draws in the next fuel/air charge more efficiently.

Metal Fatigue

JET-HOT increases the endurance limit (fatigue strength) of most alloys subjected to stress loads, such as vibration produced by an engine, after exposure to high temperatures. In addition, JET-HOT does not contribute to hydrogen embrittlement, a condition associated with chrome and other coatings in which microscopic cracking can lead to premature and sudden part failure. The comparison to the right represents the average performance of 403 stainless steel, uncoated and coated with JET-HOT, after 10-million stress cycles. The results demonstrate how effectively JET-HOT protects substrates from thermal fatigue.
