When it comes to high-performance engines, managing heat is crucial. Excessive heat can damage engine components, reduce performance, and even lead to costly repairs. Many car enthusiasts and mechanics have turned to heat wraps to mitigate this issue, but there is a more advanced solution available today: ZyBar, a high-temperature, heat-dissipating thermal exhaust coating. In this post, we’ll compare heat wraps to ZyBar, exploring their effectiveness, features, and why ZyBar is a far superior choice for engine heat management.

What Are Heat Wraps?

“Cheap, yes – but you get what you pay for” said Tim McCarthy, Founder of ZyCoat. Wraps void component manufacturer warranty. Heat wraps, often made from materials like fiberglass or basalt, are designed to wrap around exhaust components, such as headers, downpipes, and exhaust manifolds. The primary goal is to insulate these components and reduce the amount of heat they radiate, keeping temperatures under control within the engine bay. Heat wraps can be effective at reducing radiant heat, keeping the surrounding areas cooler, and improving exhaust flow. However, while heat wraps can offer some benefits, they come with limitations.

The Drawbacks of Heat Wraps

1. Durability Issues: Heat wraps wear down over time due to exposure to extreme temperatures, moisture, and general wear and tear. They fray, degrade, and eventually lose their insulating properties. This means heat wraps void component warranty. They may need to be replaced regularly, which is both time-consuming and costly.

2. Moisture Retention: Heat wraps absorb moisture, which not only leads to corrosion of the wrapped components but can also reduce the wrap's effectiveness over time. When moisture is trapped, it can lead to rusting and degradation of engine parts, shortening their lifespan.

3. No Heat Dissipation: Heat wraps trap heat within the exhaust components, they can’t dissipate the heat efficiently. Instead, they keep the heat contained, potentially causing the exhaust components to heat up to even higher temperatures. Increase internal radiant heat which increases back pressure and reduces performance. This could lead to potential issues such as thermal stress or premature wear on engine parts.

4. Difficult Installation and Maintenance: Installing heat wraps can be tricky and requires patience and expertise. The wraps must be tightly secured around engine components, which can be difficult to do in cramped engine bays. In addition, once wrapped, it can be challenging to inspect, repair, or replace any part underneath the wrap.
   
   

Enter ZyBar: The Future of Heat Management

ZyBar is an advanced thermal exhaust coating designed to outperform traditional heat wraps. It is formulated to withstand extremely high temperatures and provide superior heat dissipation and protection for engine components. Unlike heat wraps, ZyBar doesn’t just insulate—it actively prevents metal from absorbing heat works to reduce radiant heat buildup, improving both the efficiency and longevity of your engine components.

Features of ZyBar:

1. High-Temperature Resistance: ZyBar is engineered to withstand ambient temperatures up to 2,100°F (1,150°C) and 1,600°F (871° C) metal surface temperatures, making it ideal for use in extreme environments like high-performance engines. It can handle the heat generated by turbocharged or supercharged engines without breaking down or losing effectiveness.

2. Thermal Dissipation: Unlike heat wraps that trap heat, ZyBar actively dissipates heat. Its unique formulation helps to reduce exhaust temperatures by spreading heat more evenly, lowering the overall temperature of the engine bay and reducing the risk of overheating. This not only keeps the underhood cooler but also protects surrounding parts from excessive heat damage.

3. Long-Lasting Durability: ZyBar's robust coating forms a durable, heat-resistant layer that can last the lifetime of the engine, making it a more cost-effective and low-maintenance option compared to heat wraps. It won’t fray, degrade, or need to be replaced regularly, even under extreme conditions.

4. Corrosion Resistance: Unlike heat wraps, ZyBar won’t absorb moisture, which means it doesn’t contribute to rust or corrosion. This protection extends the life of your exhaust components, ensuring that they maintain peak performance without the risk of corrosion over time. ZyBar passed over 600 hours of continuous salt spray testing with no corrosion.

5. Improved Exhaust Flow: ZyBar’s ability to dissipate heat leads to better overall exhaust flow, reducing back pressure and enhancing the performance of your engine. Cooler exhaust components mean less heat stress on the engine, which can translate into improved power output and fuel efficiency.

6. Easier Application: Applying ZyBar is a straightforward process. ZyBar bonds to itself.  If you miss a spot after its cured, simply apply more over the missed area.  Making it much easier and less labor-intensive than installing heat wraps. It also doesn’t require the tight, complicated installation that heat wraps do. You can apply ZyBar in your shop or take it to your local powder coater.
   
   
   

ZyBar vs. Heat Wraps: A Clear Winner

When comparing ZyBar to traditional heat wraps, it’s easy to see why ZyBar is the superior choice. While heat wraps might offer limited short-term heat insulation, ZyBar’s advanced features provide a more comprehensive solution for high-performance engines and thermal management. Here’s a side-by-side breakdown:

 

The Bottom Line

For those looking to optimize their engine’s performance and longevity, ZyBar is the clear winner. While heat wraps may serve as a quick short term fix for reducing heat in the engine bay, they come with significant limitations in terms of durability, performance, and maintenance. ZyBar, on the other hand, offers superior heat dissipation, long-lasting protection, and a host of benefits that make it the best choice for any performance vehicle or high-temperature application.
