Superchargers and turbochargers are an incredibly popular way to make gobs of power and maximize the efficiency of your vehicle—and Summit Racing Equipment has the best selection around! Let’s break down the main differences of each, so you can figure out what route to take on your own ride!
Superchargers are driven directly by your engine. They are attached to your crankshaft by a belt, so as engine speed increases, so does your supercharger speed. You can increase or decrease the speed of the supercharger by changing the size of the pulleys, allowing you to fine-tune your boost to the desired level. Because of their relationship to engine speed, superchargers commonly provide a power curve that increases with engine rpm, delivering boost with rapid response.
There are two main styles of superchargers: Roots and centrifugal. Roots-style superchargers use a pair of rotors within a housing to force air at higher than atmospheric pressure into your engines. The rotors can have a varying number of lobes and may be twisted, affecting how the air flows through the supercharger. Centrifugal style superchargers utilize a gearbox to spin a shaft, which is connected to compressor wheel, drawing in ambient air and compressing it on its way to the engine.
Turbochargers utilize the exhaust gases produced by your engine to spin a turbine wheel located inside the turbocharger housing, which is connected to a compressor wheel by a shaft. As the two wheels turn, ambient air is sucked into the turbocharger’s compressor inlet and pushed into the engine. That air charge is often passed through an intercooler to increase its density.
Choosing the right turbocharger kit for your vehicle can be daunting, with factors like tubing size, A/R ratio, and multiple other factors to consider. However, Summit Racing makes it easy by offering turbocharger kits custom-designed for a wide range of vehicles, so you can get all the benefits without major engineering work.

Summit Racing™ 50MM blow-off valves are a pressure release system that takes the load off your turbocharger when the throttle is suddenly closed, preventing damage to both the turbo and your engine. These valves are adjustable from 0 to 50 psi, making them ideal for most boosted applications. Machined from aluminum and black anodized for durability, these blow-off valves offer a quality look for any turbo setup. They include vacuum fittings, aluminum weld flange, V-band assembly, and springs.

Go Fast Bits VTAs are a performance blow-off valve solution for a wide range of foreign and domestic cars and trucks with an electronic factory diverter valve. If you want sound with your performance (or performance with your sound!), these VTAs offer just that! By combining the proven performance benefits of GFB's ground-breaking DV+ with atmosphere venting, the VTA delivers an aggressive blow-off sound, improved throttle response and boost recovery, as well as superior boost holding and reliability in extreme conditions. The VTA shares the successful DV+ design philosophy: "Keep what works, replace what doesn't." This means Go Fast Bits retained ECU control and the solenoid from the factory diverter to ensure the fastest possible response time—without the added and unnecessary cost of replacing the solenoid like some brands do. The weak part of the factory diverter has always been the plastic valve mechanism; this is the part GFB has replaced. The VTA features CNC-machined billet components that last a lifetime, and the valve operation method has been updated for better performance. The factory diverter valve can only operate in two states: open or closed. When it opens fully at low boost or during a partial throttle lift mid-corner, it causes increased lag and a noticeably non-linear boost transition. GFB pioneered the use of "pilot operation" in the DV+, which works by re-purposing the factory solenoid to control the pressure behind the piston rather than the piston itself. This allows the solenoid stroke to be much shorter, speeding up the response time and increasing the actuation force. More importantly, it allows the piston to open and close progressively in response to the amount of boost pressure present, which smooths boost transitions and reduces the lag caused by the factory diverter valve. It's this design philosophy that makes the VTA not only the best performing blow-off valve solution, but also the best value on the market. Order the VTA Performance blow-off valve model recommended for your vehicle. Key features: * TMS Technology for faster boost recovery on gear shift and during throttle modulation * Improved boost holding ability * Atmosphere venting for blow-off sound * Retains ECU control * Simple, direct bolt-on kits include everything you need to install

The Hybrid valve is back! Go Fast Bits Hybrid dual outlet valves are three valves in one; full recirculation, full atmosphere, or 50/50 venting. In 1999, GFB's first Hybrid valve pioneered the dual port design, which was so successful, and the technology has since been adopted by most other brands. By "staging" the two venting outlets at low valve lifts most of the air is recirculated. As the car is driven harder, the valve opens further and more of the atmosphere venting port is exposed for a louder sound--a benefit that makes it possible to use these valves on cars with sensitive airflow meters that often suffer issues such as backfiring and/or stalling, whilst still achieving the signature blow-off sound. Go Fast Bits Hybrid dual outlet valves are direct-fit, bolt-ons with a range that covers a huge list of popular vehicles. Purchase the Hybrid model for your vehicle.

Go Fast Bits Respons TMS Universal blow-off valves with TMS Advantage are patented adjustable venting bias system diverter valves. GFB's Respons BOVs allow you to precisely control how much air expels from each of the two outlets, which is key for two reasons. First, you can adjust how loud the blow-off sound is--recirculate all of the air for silent factory operation, vent it all to atmosphere for maximum noise, or set it anywhere in between to suit your preference. Second, you get a blow-off sound without causing stalling, backfiring, or any other BOV-related issues, even on a car with a sensitive airflow meter (MAF). And this is accomplished by simply twisting the adjusting ring. GFB's Respons TMS Universal blow-off valves are not just noisemakers. They also offer better throttle response, faster boost recovery on gearshift, and unlimited boost-holding. Using GFB's TMS (Turbo Management System) principle, tests show that Respons valves can return the engine to peak boost up to 30 percent faster than a factory diverter valve when shifting gears.
