The turbine wheel&rsquo;s shaft passes through some bearings and on the other end of that shaft is the impeller, which is in the intake stream.<\/p>\n\n\n\n<p>The faster the exhaust flow, the more intense the impeller&rsquo;s action at forcing the air into the plenum, pressurizing. Naturally aspirated (non-turbo) engines depend on the movement of the pistons and the opening of the valves to create less than atmospheric pressure to &ldquo;draw&rdquo; the air in.<\/p>\n\n\n\n<p>The turbine wheel helps compress incoming air, forcing more air and fuel into the combustion chamber, so the engine can fire faster and more powerfully than a naturally aspirated system.<\/p>\n\n\n\n<p>When working with a turbocharger, it&rsquo;s important to position the component near the exhaust manifold. This lets hot exhaust pass through the unit with minimal heat loss.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"682\"

A small turbo rotates faster and provides a significant boost under low speeds.<\/p>\n\n\n\n<p>Meanwhile, a big turbo can produce more boost and horsepower at high speeds.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Types of Twin Turbos<\/h2>\n\n\n\n<p>There are several types of twin-turbo setups: parallel, series, twin-scroll, sequential, and cross-bank.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Parallel Twin Turbo<\/h3>\n\n\n\n<p>Two turbochargers of the same size are used in a parallel twin-turbo setup. Typically installed in V6 and <a href=\"https:\/\/www.carparts.com\/blog\/what-does-v8-mean-a-quick-guide-to-v8-engines\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"V8 engines\">V8 engines<\/a>, a parallel twin turbo is considered the most common aftermarket twin-turbo design.<\/p>\n\n\n\n<p>The parallel design equally divides the exhaust gases for each turbocharger. Each turbocharger is assigned to one cylinder bank to minimize exhaust piping.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Series Twin Turbo<\/h3>\n\n\n\n<p>In a series twin-turbo setup, the turbochargers work in a sequence. The first turbo boosts the initial intake charge while the second compresses air.<\/p>\n\n\n\n<p>Series twin turbos can generate large boost levels at lower RPMs, making them ideal for diesels, boats, and airplanes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Twin-Scroll Turbo<\/h3>\n\n\n\n<p>A twin-scroll turbo uses two separate exhaust paths to drive one impeller under a single housing.<\/p>\n\n\n\n<p>Similar to a parallel design, a twin-scroll setup separates the exhaust in half. Doing so can maximize exhaust efficiency while permitting a wide overlap camshaft profile.<\/p>\n\n\n\n<p>A twin-scroll turbo is commonly found in smaller engines, particularly four and six-cylinder systems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Sequential Twin Turbo<\/h3>\n\n\n\n<p>In this setup, one turbocharger can be used for low-speed efficiency while the other is for high-speed efficiency. In some cases, both turbochargers function at high speeds.<\/p>\n\n\n\n<p>The design of a series twin turbo eliminates the problem of turbo lag because the turbochargers work in a sequence. However, this type is considered to be less efficient than others.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cross-Bank Twin Turbo<\/h3>\n\n\n\n<p>The cross-bank twin turbo is BMW&rsquo;s version of the twin-scroll turbo intended for V-shaped.<\/p>\n\n\n\n<p>engines. This design features two twin-scroll turbos that feed half of each bank.<\/p>\n\n\n\n<p>Having a cross-bank twin turbo setup also means that the engine is operating backward, with the exhaust coming through the interior of the V and the intakes outside of the V.<\/p>\n\n\n\n\n\n\n<h2 class=\"wp-block-heading\">Can You Install a Twin Turbo on a Four-Cylinder Engine?<\/h2>\n\n\n\n<p>Yes. It&rsquo;s possible to install a twin turbo on a four-cylinder engine. You can add one turbo for each cylinder.<\/p>\n\n\n\n<p>Installing a turbocharger is a great way to draw more power from a small engine without compromising fuel economy.<\/p>\n\n\n\n<p>However, it&rsquo;s important to consider the powertrain and model first before installing a turbocharger on a small engine to ensure its reliability in the long run.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can You Supercharge and Install a Twin Turbo on a Single Car?<\/h2>\n\n\n\n<p>Yes. Twin charging is the process of combining a supercharger and a turbocharger to generate significant power gains.<\/p>\n\n\n\n<p>Twin charging is usually done on custom builds, high-performance street cars, and racing applications. A hybrid induction system is required to accommodate a twin charger.<\/p>\n\n\n\n<p>In a twin charging setup, the supercharger provides instant boost at low RPMs to eliminate turbo lag. As exhaust gases flow, only then will the turbocharger start its operation.<\/p>\n\n\n\n<p>Twin charging aims to capitalize on the strengths of both the turbocharger and supercharger while mitigating their shortcomings.<\/p>\n\n\n\n<p>A broad power band, reduced turbo lag, and increased torque are some of the benefits of twin charging.<\/p>\n\n\n\n<p>However, flexibility is arguably the setup&rsquo;s strongest suit, as it can adapt to various driving conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Much Is a Twin Turbo?<\/h2>\n\n\n\n<p>Installing a twin-turbo system can cost anywhere between $4,000 and $6,000, depending on several factors.<\/p>\n\n\n\n<p>The twin turbochargers alone can cost around $1,500 to $4,000. Depending on your engine setup, you might need to add a few more components, including an intercooler, blow-off valve, and wastegate, among others.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where to Buy a Replacement Turbocharger<\/h2>\n\n\n\n<p>While your vehicle&rsquo;s old turbocharger might not match up to a twin turbo, you might be surprised at the difference a new turbocharger can make. Having a mechanic replace your vehicle&rsquo;s old turbocharger with a new one might bring enough power back to keep you satisfied for a long time.
