Lubrication is crucial for turbochargers spinning at super high speeds. Traditionally, engine oil has been used to lubricate turbocharger bearing systems, but it comes with limitations and hassles. Oil-lubricated systems offer limited mounting options as oil needs to flow back into the engine by gravity, unless you use expensive and complex scavenging systems. They're also prone to contamination from engine wear, leaks, and smoking. Comp Turbo got inspired to ditch engine oil in turbocharger bearing systems and solve these issues. Their innovative design led to the world's first production oil-less water-cooled turbocharger! The patented CTR Oil-Less Turbochargers use a Triplex Ceramic triple ball bearing system lubricated with a special high-quality non-channeling grease. The bearing housing has a water jacket for cooling and a Zerk fitting for easy servicing. Comp Turbo ball bearing turbochargers have a patented triple ball bearing design with 99% mechanical efficiency! This means faster transient response compared to the industry standard dual ball bearing system due to less friction loss. It greatly improves response times and maximizes power output! Our patented Triplex Ceramic bearing system is in a billet aluminum cartridge, making our turbochargers 5 to 12 pounds lighter on average. Our full line of turbochargers is proudly made in the USA and features our latest R-Line technology. It includes the CTR 7/14 veined billet slim hub extended tip compressor wheel and high efficiency CTR slim hub high flow turbine wheel, our most advanced rotor technology yet. Features: • Titanium Bullet Nose • Fully Rebuildable/Upgradeable • Anti-Surge Compressor Housing • CTR Compressor and Turbine Wheel • Triplex Ceramic Oil-Less Bearing System • Can be mounted in any orientation • Eliminates oil lines CTR Compressor Wheel Technology: The CTR-line turbochargers have a 7 - 14 vaned compressor wheel with the latest compressor design technology. It has a small-diameter hub to maximize intake airflow and an extended tip for better efficiency at high pressure ratios. The R-line design features, like large inducer diameters, create higher boost pressures at high engine speeds and can increase engine HP output by up to 15%. The R-line advanced design compressor wheels are available on our whole CT turbocharger line. CTR High Flow Turbine Technology: The CTR Turbine wheels have 25% lower inertia, which means faster rotor acceleration. The slim hub and thin blade design make it unique and maximize the flow capacity, 30% more than the old GT style Turbine wheel. The Comp Turbo CTR high flow turbine wheels have low leaving velocity because of the long blade surface, reducing losses. This leads to higher turbine efficiency and a wider flow range than other turbine wheels in the industry. CTR turbine wheels are designed for high exhaust flow and have low leaving gas velocity to boost turbine efficiency. Turbochargers are built to order and take 3 to 5 weeks to deliver.
Using your Comp Turbo CTR3893S-6767 turbocharger is straightforward. First, make sure it's installed correctly in your engine. Since it can be mounted in any orientation, you have the flexibility to choose the best position for your setup. Just remember, this turbocharger is built to order, so it'll take 3 to 5 weeks to arrive. When it comes to maintenance, the Zerk fitting on the bearing housing makes it easy to service. You don't have to worry about oil lines, as this is an oil-less turbocharger. But you do need to keep an eye on the water jacket for cooling. Make sure the water flow is consistent and there are no leaks. If you notice any issues, like a drop in performance or strange noises, it's a good idea to check the Triplex Ceramic bearing system. The turbocharger is fully rebuildable and upgradeable, so if you want to improve its performance over time, you can do so. Also, the anti-surge compressor housing helps keep the turbocharger running smoothly, but it's still important to operate your engine within the recommended parameters to get the most out of your turbocharger.
