Modern Engine Coating(s):
Modern Ceramic coating is the same space age,
ceramic that NASA uses in the Space Shuttle Program. It provides
protection from heat, flame, fire, combustion, exhaust, and will not
wear, chip, flake, or burn off. Teflon low friction coating provides a
reduced friction surface for any metal to metal contact. "Non-Wetting"
or "oil shed" coating is used to help cool items that have direct
contact with lubricating oils(Crankshafts, Connecting rods, and windage
trays). Powder Coating is both protective and decorative, and lasts
much longer than paint.
Types of Coatings and their usage:
"TBC/"Ceramic" Ceramic Thermal Barrier:"
For most naturally aspirated and mild boost motors TBC/"Ceramic"
is our tried and true ceramic thermal barrier coating. DPRs
TBC/"Ceramic" has come a long way since it started the internal
engine coating revolution back in the 1970s. Now in its 5th
generation of development, DPRs TBC/"Ceramic" uses
DPRs exclusive Smart Coat technology which allows the
ceramic to expand at the same rate as the piston. TBC/"Ceramic"
coated pistons run cooler and retain much more of their tensile
strength. TBC/"Ceramic" protects against high temperature
oxidation, eliminates hot spots, and encourages proper flame travel.
The ceramic also spreads the heat evenly over the entire coated surface
reducing detonation, pre-ignition and allowing the use of lower octane
fuel. Less heat is conducted through the wrist pins and rods keeping
the crank, bearings, oil and entire bottom end cooler.
TBC/"Ceramic" is effectively used on cylinder heads, intake
manifolds, brake calipers and other areas where the reduction in heat
transfer is desirable.
"GoldCoat Ceramic Armor Ceramic Thermal
Barrier:" As the use of Nitrous Oxide, Turbo Chargers and Super
Chargers have become common place; DPR's Performance developed
GoldCoat Ceramic Armor to protect piston tops in these
demanding motors. GoldCoat offers the same benefits of
TBC/"Ceramic", but adds an extra layer of extra high temperature
ceramic to provide even more protection at higher temperatures.
GoldCoat deals with the heat spikes and thermal shock of boosted
motors better than any other piston coating.
Moly Solid Film Lubricant:" In addition to power being
lost through heat, power is also lost due to excessive friction. Poly
Moly has an extremely low coefficient of friction, reduces
scuffing caused by piston movement and provides back-up lubrication if
your primary lubrication fails or has gone beyond its load limits.
"PC-9 Solid Film Lubricant:" PC-9 is
DPR's Performance Coatings' latest generation of piston skirt coating.
PC-9 has the same low friction properties of Poly Moly, but
PC-9 is even tougher.
solid film lubricant:" is thin, tough
coating applied to bearing shells to reduce friction and improve the
wear life of both the bearing shells and journals under normal
operating conditions. However, it is when operating conditions are less
than ideal that PPM really goes to work. If there is a cold
start, oil starvation or any other situation where the primary
lubrication is less than ideal, PPM will provide a solid film of
lubrication to prevent a catastrophic failure.
"BBE" is for parts where you want to get heat out of a part instead of holding it in a part, our BBE coating is applied to help pull heat out of base metal. BBE is commonly used on intercoolers, air cooled cylinders, air cooled heads and brake calipers. Though the primary purpose of the coating is to improve cooling, the coating does offer a durable semi-gloss black finish.
Exhaust system/header/manifold coating:
Like all of DPR's Performance s coatings, White Lightning is a performance improving coating. What makes White Lightning the best performance exhaust coating?
1) White Lightning really is ceramic so the material is a superior insulating material.
2) White Lightning is applied much thicker than any of the cosmetic coatings. White Lightning is applied about .015 thick compared to about .002 thick for the cosmetic coatings. Because White Lightning is the best insulating material and it is applied thicker than any other coating, White Lightning offers performance improvements that cannot be matched.
Many companies apply the shiny or colored paint based coatings and call them ceramic. Those thin shiny coatings are very different than DPR's Performance White Lightning.
Whereas it would be more accurate to call those thin shiny coatings good high temperature paints that may have a very small amount added to them, DPR really uses a ceramic coating that is applied molten where it bonds and cools directly on the substrate.
After heat has performed its function in the combustion chamber, it travels out the exhaust port and into the exhaust header or manifold. If the gases are allowed to cool they lose velocity and the scavenging effect is reduced. By insulating the exhaust system, gases inside are kept at the highest possible temperature resulting in greater exhaust gas velocity and higher efficiency.
White Lightning insulating headers typically reduces radiant heat by about 35-55%. This reduction in radiant temperature will decrease under hood and cockpit temperatures. Lower under hood temperatures lead to lower intake temperatures. A 10°F reduction in intake air temperature provides a 1% increase in horsepower. A 30°F reduction equates to a 3% horsepower increase.
Because White Lightning really is a ceramic, it is not possible to offer color choices like you can get with paint based coatings. However, the white textured finish of White Lightning makes it an ideal base for a good high temperature paint if you want to change the color of the coating. The high temperature paints bond well to the natural textured finish of White Lightning and the paint will not impact the effectiveness or durability of the White Lightning coating.
How durable is the coating? It is so durable that you would need to grind it off to remove it and it would take a significant amount of time to grind the coating off in one small area. If you mar the coating with wrenches you tighten up the header to the motor or against the frame rails when you guide the motor into place you will not damage the coating. You can make that area that was marred shiny, but it will not damage the coating or degrade its insulating value.
DPR's Performance Coatings do not give White Lightning an official temperature rating because temperature ratings really mean nothing when dealing with exhaust parts. The melting point of White Lightning is over 3,000°F and there are applications where the coating would stay completely intact at temperatures well above temperatures that can be reached on exhaust parts. However, what can damage our coating or any coating, no matter what the temperature rating is would be if the base metal of there is a differential of expansion between the base metal and the coating greater than what any coating can expand. If the base metal does get hot enough to expand more than what a coating can expand, there is the possibility any coating can fracture. Whether the coating is rated for 1,300°, 1,400°, 2,000°F, or in the case of White Lightning, about 3,000°F, it is possible that a coating will get damaged if your parts get hot enough to glow. If you ask around to those who have had coatings done with temperature ratings, it is easy to find people who will confirm that the temperature ratings really mean little in a real world environment.
On naturally aspirated motors (non-turbo), we will typically coat the inside of headers as deep as possible. However, if we think the coating will interfere with the fit of the header to the motor or the header to the mating exhaust part, we will typically mask off those surfaces. Remember our coating is about .015 thick, not a thin paint. If there is masking you want to have done, be sure to let us know by marking this right on the part with a marker so we know what you want. If you want us to coat the inside of the part, let us know so we can process the part the way you want. We do not coat the inside of mufflers, catalytic converters or expansion chambers because they are not very accessible and there is very little coating that would bond to the inside of the parts.
The most critical step in getting a coating to achieve a tenacious bond to the base metal of an exhaust part is by applying a good abrasive blast on the part at about a 90° angle to the substrate. Simply put, there are few exhaust parts that are open and accessible enough to apply this type of blast. If a good blast cannot be obtained there is no possible way a permanent bond will be achieved. This is why we take the time to mask off the interior surfaces of turbo parts. For the small amount of area that a good bond can be achieved on, it is not worth taking the risk of coating the inside where the coating could come off and damage the turbo.
It is much easier to simply coat a part all over instead of taking the time to mask a part and process it properly. We would only coat the inside of a part if it makes sense to coat it or if it has been requested by the customer. If it does not make sense to coat it or if it has not been requested by the customer, we will take the time and effort to mask the part.
When choosing which exhaust coating to have applied to your exhaust parts you should consider what you want the coating to do for you. If you want the best insulating and most durable exhaust coating available, DPR Techs White Lightning is the only coating to consider. It simply is not possible for the .002 thick paint based coatings that many other companies offer to insulate nearly as well as the .015 thick true ceramic White Lightning coating that DPR's Performance offers. However, if the look of the coating is the primary purpose for the coating, White Lightning may not be your best choice. Though White Lightning is an attractive white textured coating it cannot provide you with the brilliant shine that can be achieved with the paint based coatings. If the shiny look is more important than the function of the coating, there are now many companies that offer that service. DPR's Performance Coatings would recommend using a company with a national presence that has been around for a while.
If performance is what you are after and you consider the facts about coating materials, the effectiveness of coating the inside of parts (or lack of), and temperature ratings, it is easy to see that White Lightning is the only choice. For those only wanting a shiny look, we actually recommend that they not use our coating. With more than 25 years of developing and applying the leading performance improving coatings, DPR's Performance Coatings will give you the coatings and honest advice needed to get the best coating for your specific application.
is a proven process that has been utilized for
many years in the racing and automotive industry. WPC is not a
coating, it is a treatment that enhances the surface to reduce friction
and strengthen engine parts.
DPR's Performance Coatings' performance improving coatings for internal engine and exhaust parts are a perfect fit for the 2 cycle market. Because every stroke of the piston on a 2 stroke is a power stroke, these motors achieve power 4 strokes simply cannot make all other things being equal. Unfortunately, 2 strokes are also very limited from a lubricating and cooling standpoint. This is why DPR's Performance s coatings are essential for 2 stroke motors.
Snowmobiles, motorcycles, ATVs, watercraft, competition saws and other applications all benefit from the power and durability gains that DPR's Performance s thermal barrier coatings and friction reducing coatings provide.
With DPRs coatings, any type of piston can be reliably used in a 2 stroke. Do not mistake DPRs coatings with the basic break in coatings some factory pistons are treated with or a simple plating or anodizing process done to a piston. DPRs advanced thermal barrier, friction reducing, lubricating and heat emitting coatings have all been developed to be permanent functional coatings. Many pistons that have been DPR's Performance coated would at least double the useful life. This extension of part life is in addition to the power gains DPR's Performance s coatings offer.
In the early 1970s ceramic engineer Dan Swain developed the first successful ceramic thermal barrier coating. Dan took this technology and perfected it in both his own NASCAR modified and with leading NASCAR Winston Cup (now Nextel Cup) teams. In 1981, Swain Tech Coatings was started to provide race teams and performance enthusiast with performance improving coatings, and has remained the coating industry leader by continually developing coatings that allow customers to achieve power and durability gains that simply would not be obtainable otherwise.
Despite extensive research and design improvements from the major two stroke manufacturers over the years, piston failure remains a nagging problem. How do you extend the life of pistons? Simply put, COATINGS.
DPR's Performance Coatings is the original high performance coating company. They have been developing and applying high performance coatings for over 20 years and are widely recognized as the industry leader.
DPR's Performance applies their ceramic TBC/"Ceramic" to the top of pistons, holding heat in the combustion chamber where that heat can be used to power the motor, rather than dissipate through the piston where it can weaken and burn the piston. This allows the piston to run much cooler and stronger. Piston skirts are coated with PC-9, a low friction/anti-seize coating to reduce frictional loses and piston sticking.
To further improve the thermal efficiency of the two stroke cylinder, DPR's Performance often applies TBC/"Ceramic" to the domes of the heads and the exhaust ports, keeping the heat where it is needed to make power and out of the areas that lead to failures. Expansion chambers are often coated with DPR's White Lightning exhaust coating to keep exhaust gases as hot as possible, allowing the motor to breathe better. White Lightning is the only true performance available. This three layer ceramic coating keeps a tremendous amount of heat inside the pipes.
To get most life and performance out of your two stroke motor, DPR's Performance 's high performance coatings are the most economical and beneficial modification you can add.
Frequently Asked Questions About Coatings
Why should I use
Coatings provide added performance and protection at a very reasonable cost. Calico also offers unequaled tech service to help you with your selection and application for all your coating needs and more.
Will I have to change
CT-3 dry film lubricant used on pistons is 0.0005" to 0.001' thick. With as many different piston materials on the market today, there are no typical clearances. However, CT-3 coated pistons can be installed with tighter clearances then any other uncoated piston. Tighter piston to wall clearance will result in faster sealing and longer ring life, with less loss of power due to blow-by or for partially sealed rings.
How long will the
What Should I
What other benefits can I expect from DPR Performance coatings?
There are many "hidden" benefits to using DPR Performance Coatings. Engine builders using CT-1 coated engine bearings save time and effort during rebuilds by not having to change and refit new engine bearings. CT-1 coated engine bearings have greatly extended service life over uncoated bearings. Engine builders have also seen reduced damage in engines from heat and lubrication-related failures.
Coated transmission and rear end housings as well as gears and shafts reduce operating temperatures by 30 degrees or more. Coating heat shields, cowlings, air cleaner housings, and exhaust systems reduces under-hood temperatures. Coating brake pads, calipers, and caliper pistons extends pad life and reduces or eliminates boiling of the brake fluid. The list goes on and on. Coatings are economically priced. In many instances, engine builders and car owners have saved considerably more by using coatings than the initial cost of having parts coated.
