What about Power?

• One of the first questions asked about High Heat Coatings is;  Will I make more Power?  The answer is YES!  Assuming of course that you are referring to high heat coatings that directly affect power, not those designed for other purposes.
• Power is increased a number of ways
• reduced friction
• increased combustion chamber efficiency, increased exhaust gas velocity
• reduced carb air inlet temperature, reduced intake manifold temperature
• reduced fuel drop out
• reduced heat transfer to incoming air/fuel charge
• increased flow through ports, these are just a few examples
• In addition power will also be affected through the ability to make changes in:
• Timing
• Clearances
• Jetting
• Additional Powers gains are found in areas where by increasing part life Power Levels are maintained.  As an example if valve springs begin to fatigue the engines ability to maintain maximum RPM's is affected.  If clearances begin to loosen then maximum power is reduced.  If parts begin to gall, friction increases robbing you of Power.  If excessive heat builds in parts maximum utilization of power is lost such as when brakes get too hot.

Coating Benefits

• What are the benefits of High Heat Coatings?
• Why should I used them?
• Do I really need them or is it only the top teams that are trying to get every little bit of performance regardless of cost?

• Increased H.P. and Torque
• Increased lubrication protection
• Reduce Friction
• Reduce part temperature
• Increase combustion chamber efficiency
• Reduce detonation
• Oxidize fuel more efficiently
• Shed Carbon
• Keep heat in the combustion chamber and exhaust system
• Reduce fuel speraration
• Extend part life

• Depending on the coating, part life increases from two (2) to ten (10) times what is normal can be see.  The dry film lubricants may burnish until they are no longer visible, however the active materials are bonded into the pores of the parts and ocninue to provide protection.

• Parts will run cooler.  Engine oil and water temperatures have shown a reduction.  On headers the radiated heat will be substantially reduced leading to lower underhood temperatures and less heat absorption.

• The dry film lubricants will burnish as they run until they are no longer visible.  They are applied at thicknesses ranging from .0005" to .0015".  However before assembly the coating may be burnished back to less than .0002" with gentle buffing using "Scotchbright" or similar material.  NO CHANGES need to be make in clearances due to the use of these coatings, through in many instances because of the reduced part temperature and increased lubrication tighter clearances may be run.
• All machine work should be done first.
