Why should I use reflective materials?
Reflective materials reduce heat soak to interiors, keeping drivers cool. They also block heat from floorboards, gas tanks, fairings, transmission tunnels, and engine components. Heat reflective materials also protect wires, cables, hoses, pipes and tubing from radiant heat sources that could cause damage or shorten component life, and prevent things like vapor lock or starter heat soak.
How do these reflective materials work?
The outer layers reflect heat away like a mirror, while the glass fiber backing layers insulate and protect. Simple peel and stick application on selected products make quick work of protecting critical areas, while others can attach with hook and loop enclosures.
What’s the difference between Reflect-A-Gold and Reflect-A-Cool? Why would I pick one over the other?
Gold reflects 17% more heat than Cool, but Cool is more affordable. Use Gold in the areas where heat is most critical. Use Cool everywhere else.
Can I use Heat Shroud on my exhaust pipes?
Nope. Heat Shroud is meant to keep cold things cold. The exhaust pipes would burn it up.
Are any of these materials electrically conductive?
Yes, the aluminized sheets are. You’ll need to insulate any open connections where they might come into contact.
How do I wash my Oil Rug?
Oil Rug isn't meant to be washed and re-used. Just keep it until it's too full or dirty to keep around, then toss and lay down a new one.
I want to place an international order, but the shipping is really expensive! Can you help me?
Yes! We have other shipping options available for offline orders. Contact us here.
How does BOOM Mat Damping Material work?
BOOM Mat dampens sound as it hits body panels by absorbing the tiny vibrations they impart. It does this by adding mass to the panels which increases the rigidity of the panel. Less vibration means less noise.
How effective is BOOM Mat?
In our show demonstrations, we use a small 1” inch square piece of Boom Mat applied to a large 20” inch percussion cymbal. When the cymbal is struck it produces virtually no noise, only a short, low-pitched clank.
PSA? What is that?!
It's not a Public Service Announcement like you're thinking! It stands for Pressure Sensitive Adhesive, or "Peel n' Stick Adhesive" as some like to say.
What is the temperature range of BOOM Mat?
BOOM Mat should be installed while the ambient temperature is 60°F or greater to ensure proper adhesion. Once installed, it can maintain adhesion from -30°F to 300°F.
How much BOOM Mat do I need?
For most vehicles we recommend 50% coverage of the area with our standard 2 mm thick BOOM Mat material. For customers with larger, more powerful audio systems, we have BOOM Mat XL. At 4 mm thick, it can be used to cover more area maximizing the vibration damping effect.
How should I install BOOM Mat?
BOOM Mat install requires little prep work. As with any adhesive material, the surface must be free of any debris. Once cleaned, cut BOOM Mat into the desired shape necessary for the area of coverage; strips or squares work well. Peel off the paper backing and place in large, flat areas like the floor, doors, body, and ceiling.
What tools do I need to install BOOM Mat?
A utility knife or scissors will be required for cutting. You may also need basic hand tools to remove door panels and trim. A roller can be used to apply even pressure on all surfaces to ensure proper adhesion.
What's the best way to apply Boom Mat headliners?
BOOM Mat headliners should be installed while the ambient temperature is 60°F or greater to ensure proper adhesion. Colder temperatures will prevent the adhesive backing from curing properly. Hold firmly to the ceiling as gravity can work against the adhesive before it's fully cured. For vehicles with removable tops, we recommend removing the roof and turning it upside down to ease installation.
Why do I want to wrap my headers, pipes, or tubular manifolds?
Wrapping pipes helps control exhaust temperatures and reduces radiant underhood heat. Hot exhaust gases flow faster, improving exhaust scavenging which in turn adds power. Limiting radiant heat inside the engine bay also lowers ambient temperatures for electronics, air intakes, and firewalls. Cooler components last longer and work better. Cooler drivers perform better, too!
Will your wrap work on my stock exhaust system?
Yes. You can wrap your original exhaust pipes to control heat. Wrapping stock cast exhaust manifolds can be difficult, for this application we recommend using our Form-A-Shield product. Form-A-Shield is designed to cover odd shapes and is easy to install over odd shaped parts. We do not recommend wrapping titanium exhaust pipes or manifolds.
What is exhaust wrap made of and does it contain asbestos?
First and foremost, there is absolutely NO ASBESTOS in any DEI product. DEI Traditional exhaust wrap is primarily constructed of glass fiber material with a proprietary coating. The combination helps increase the wrap’s thermal resistance when compared to other brands. Our Titanium brand exhaust wraps use basalt as their primary material. Basalt fibers can break off, but not to the degree that glass fibers do, and the basalt fibers are non-respirable (meaning they are too big to inhale).
I heard that exhaust wrap holds moisture and rusts out pipes!
Any mild steel exhaust pipe will rust over time with or without exhaust wrap. Our wraps won’t draw moisture from the air, but if you ride or drive in wet conditions without letting the wrap dry off, it can lead to accelerated oxidation. If your wrap gets wet, keep the engine running long enough to dry the wrap.
For even more protection, we recommend our HT Silicone Coating to seal and protect. Along with adding color to the wrap, HT Silicone Coating increases the longevity of your wrap by locking the fibers together.
How do I use HT Spray?
Spray on one coat at a time. Allow each coat to dry fully before applying the next coat. We recommend at least 3 coats. Cure at around 400°F for approximately 2 hours. This can be done in an industrial oven or by running the engine with the pipes installed. Note: HT spray does fade over time, so you’ll want to reapply periodically.
See our slightly modified instructions below for use with Titanium wrap.
What about using HT Spray on Titanium? Do I need to do anything special?
Titanium is durable enough that it doesn’t need HT Silicone Spray like traditional wraps, but it can still benefit from its use. It can also help you achieve the look you want. Note: HT spray does fade over time, so you’ll want to reapply periodically.
To get the best adhesion on Titanium wrap; apply one coat, let it dry, then cure at around 400°F for approximately 2 hours. This can be done in an industrial oven or by running the engine with the pipes installed. Allow everything to cool before applying the next coat. We recommend at least 3 coats on Titanium wrap.
How much heat will HT Silicone Spray block?
None. HT Silicone Spray is not a thermal barrier. It’s a reinforcement coating for exhaust wrap. It is specially formulated to withstand the temperatures seen on the cool side of exhaust wrap.
I don't have a curing oven and I can't start the engine right now. Can I spray HT Silicone Spray now and wait to cure it later?
Yes. Curing can happen at any time. Waiting will not affect it.
How much wrap do I need? What width should I get?
Check out our Exhaust Wrap Calculator to figure out how much wrap you need before you purchase. Keep in mind the calculator doesn't account for any bends or bulges, which will use a little more exhaust wrap material than a straight pipe.
How do I wrap pipes with large bulges?
It’s best to start at the larger section and work your way down to thinner sections. This will help keep the wrap tight against the pipe as it goes.
Is it ok to wrap over ceramic coatings?
Yes, however the wrap will keep heat in and eventually burn off the ceramic coating. This won’t affect the pipes, and it won’t reduce the effectiveness of the wrap.
Is it ok to wrap the catalytic convertor?
No. This will heat the convertor too much and reduce its service life. If you really need shielding there, look at our Floor & Tunnel Shield for above or near but not on the converter, or check out the Corvette C7 Catalytic Converter Shield.
Should I wet the wrap for installation?
Our traditional wraps are made of glass fiber, and do need light wetting to make them more flexible during installation. Do not totally submerge the traditional wrap, as this can wash away the coating. Be sure to let the wrap dry completely before applying HT Silicone Spray.
Do I need to wet Titanium wrap before installing it?
No. Unlike our traditional glass fiber wraps, Titanium does not need to be wetted before installing.
How do I keep the wrap from coming undone?
DEI Stainless Steel Locking Ties are designed to keep your exhaust wrap securely in place and with a finished look. Our Locking Tie Tool makes installing them quick and easy. Stainless steel hose clamps or lock wire will also work.
I just installed my exhaust wrap and now it’s smoking. Is that normal?
Yes. This is part of the curing process and will stop after a few heat cycles.
I installed the wrap, but there’s still a lot of heat coming through! Should I double the wrap?
This would potentially hold in too much heat and eventually make the metal more brittle, leading to cracks and metal fatigue. A single layer of wrap is best. If you need more insulation, then it’s time to go to the next step and add Floor & Tunnel Shield to the areas closest to the exhaust pipe.
How does Radiator Relief work?
Radiator Relief helps reduce surface tension, and essentially lubricates the system, allowing coolant to flow more efficiently.
Will Radiator Relief work with different coolants?
Yes, Radiator Relief works with all water based cooling systems.
Do I need to mix it?
No, simply pour Radiator Relief into your coolant system when it is NOT under pressure.
How many bottles do I need per system?
One 16 ounce bottle is enough for most regularly-sized domestic V8 engine cooling systems.
What's the right mix ratio for Chill Charger?
Mix 1 oz. of Chill Charger for every quart.
CryO² Cooling System
What is the CryO² system?
It is a system that uses cryogenic technology to cool the air/fuel intake charge to produce a colder denser charge. The CryO² system uses liquid CO₂ delivered through a stainless steel braided hose to a cryogenic solenoid valve and then to the first CryO² component. From there the system hops from component to component. If a CryO² Intercooler Sprayer is used it is always positioned as the last in the system because it actually vents the liquid CO₂ directly onto the fins of the intercooler.
Won’t CO₂ deprive the engine of Oxygen and stall the engine?
Yes it will, but CO₂ is NOT being introduced into the air stream. We are harnessing the cryogenic power of the CO₂ to charge various heat sinks to cool the air and fuel charge. This does bring up an excellent point…when venting the system you need to make certain the air intake is not picking up the venting CO₂. The same is true if you’re using the Intercooler Sprayer. Make certain the air intake is away from the intercooler or it could stall the motor. The Air Intake Chamber and Fuel Bars come complete with connection/venting hose. This hose either connects to the next component or enables you to decide where you want CO₂ to exit.
How does it work?
The Air Intake Chamber, Fuel Bar, and Fuel Chiller work on the premise that when a gas expands its temperature decreases. We have expansion chambers in the various components which allow this to occur. From there they act as heat sinks, actually removing heat from the air and fuel. The Intercooler Sprayer simply vents liquid CO₂ onto the intercooler fins to enhance the heat transfer.
Can I use more than one of the same component?
Yes, we have not found a limit to the number of components that can be charged at one time. To use multiple Intercooler Sprayers a “Y” fitting and additional hoses will be needed. Some of the Turbo crowd has had great success using multiple Air Intake Chambers. Use one before the turbo, one between the turbo and intercooler, and one after the intercooler- before the throttle body. They can still go to a Fuel Bar/Chiller (or two, or three, etc.) and finally to the Intercooler Sprayer.
Will it fit my car?
The CryO² system is designed to be universal in nature. The Air Intake Chamber comes in diameters of 2.5” and 3”OD to match your air intake tube. Reducers or expander sleeves can be purchased to make it fit properly. DEI does offer a CryO² Intake Bulb along with its connecting threatened legs separately (no hoses included with PN # 080119) for custom applications that are over 3” in diameter. The Fuel Bar/Chiller simply fits pre-fuel rail with your fuel system attaching anywhere on your fuel line that you are able to fit it. Fuel Bars are available with either -6AN or -10AN sizes. Fuel Bars have 2 female openings in the selected size, one at each end. You will need to buy fuel fittings to complete the installation. There were just too many options and applications to provide fittings for every vehicle on the road. The Intercooler Sprayer is universal; simply find the size that best fits the surface of your intercooler and mount it on.
What kind of horsepower does it make?
That is a tricky question because of the many variables involved in the physics of the system - base horsepower, altitude, ambient air temp, humidity, intake system, MAS airflow sensor, and intercooler efficiency can all affect the performance of the system. We tested a naturally aspirated Honda Civic with 110 base HP on an 85°F day with 72% humidity using just one Air Intake Chamber and found a 9% increase in horsepower. In this example we saw an intake temperature of 38°F and that is just with an Air Intake Chamber. Other test results have shown greater than 40HP gains, as compared to the previous heat soaked conditions, by simply activating our cryogenic components. What racer couldn’t use an extra 40 horsepower? Think about how your car performs on a nice cool fall morning… it feels more responsive and powerful. As the engine heats up it loses horsepower and becomes a little sluggish… What we have created is a way to give you that cool fall morning, on demand, and eliminate power robbing heat soak!!
How do you activate the system?
The Tank and Installation Kit comes with 3 switches. The toggle switch arms the system and allows you to activate the solenoid with either the push button or the full wide open switch. Some elect to simply activate the solenoid manually using the toggle switch. They activate the system at the staging lights and let it flow until the end of the pass.
Is this like Nitrous?
No, nitrous oxide is an oxidizer which actually adds oxygen into the intake charge. CryO² simply cools the intake charge to help reduce the effects of heat soak and provides a denser intake charge. Since we are only cooling the air / fuel, this system is non-evasive and allows you to run more boost.
I have nitrous, turbo, supercharger, etc. can I still use CryO²?
YES, the system is compatible with all of the above. Think of it this way: is your car compatible with a cold fall morning?
Can I use my old nitrous bottle with this system?
A nitrous bottle is very similar but the nitrous valve could be different from the CryO² Tank valve and the filling station might not be able to fill it with CO₂. The older CryO² bottles, with the brass valve, are incompatible. If you want to use nitrous to charge that bottle, it will work fine. Make sure the bottle has a siphon tube in place so the liquid nitrous is drawn up from the bottom of the bottle.
Where do I get my tank filled?
Welding or medical gas suppliers are great sources as they have pumps and will fill the tanks properly. Paintball shops usually carry CO₂ but they rarely use pumps. Filling the tank without a pump will not yield the full amount of pressurized CO₂. It has also been reported to us that some beverage distributors fill CO₂ tanks. CO₂ is what is used to carbonate beverages.
Can I use just the Purge Valve and not the complete purge kit?
Yes, you can use the Purge Valve assembly without the complete kit. If your installation does not include an Intercooler Sprayer a Purge Valve can be used as a vent when the CryO² system is activated. This installation will eliminate the need for a vent cap, however, an additional length of braided line may be needed. This is a very popular way to vent the CO₂. It not only vents the CO₂ to the furthest point, but it also supplies the dramatic and much desired purge effect. Many have used the Tank and Installation kit with just the Purge Valve Assembly to achieve the purge for show and attention. These installations can be easily upgraded when ready to add components.
How long will a 10lb. tank last?
It will last between 3-1/2 and 4 minutes with continuous solenoid activation. However, that would not be good for the solenoid valve. Intermittent activation to address heat soak and ¼ mile use is recommended.
How much does CO₂ cost?
CO₂ can be found for around $1.00 per pound, 4 to 6 times less than nitrous per pound.
What is the ideal CryO² installation?
Every vehicle with an internal combustion engine benefits from cooler/denser air and fuel mixtures. That is where our cryogenic system comes into play. The system can be installed in series, in any order, as long as the intercooler sprayer is the last component. Most installations start with an Air Intake Chamber, followed by a Fuel Bar/Chiller, and eventually venting to the atmosphere through an intercooler sprayer. Utilizing all three CryO² components will greatly lower air and fuel temperatures. But not every vehicle is equipped with forced induction or an intercooler. So here lies the beauty of the DEI system: our system can be pieced together to fit your needs and your budget with expandable flexibility. Customer installations range from mild to wild. Some utilize just one CryO² component while others use multiple components to maximize the cooling power of the system. Recently we have introduced our line of Purge Valves for use with any installation as either a vent for the CO₂ or to just grab attention by blasting CO₂ out of a desired location on a vehicle.
What CryO² components do you need to run the Purge Valve separately?
DEI offers complete Single and Dual Purge kits that include all the parts necessary for a basic installation. Some additional components maybe required for different installation options. We recommend adding a separate Push Button Switch (part # 080232) to activate the Purge Valve solenoid independently of other CryO² components. Depending on desired Purge Valve mounting location, additional braided hose lengths may be required.
