Turbochargers have come a long way over the years. Once considered an exotic, mysterious component by everyday racers and hot rodders, these highly effective devices have become common in almost any kind of performance car imaginable, for both street and track use.
And it’s easy to understand why – few modifications can beat the versatility, tuneability, and everyday useable power that turbochargers can deliver. A properly set up turbo can turn a mild-mannered street cruiser into a tire-shredding brawler in a matter of hours.
But, like any performance mod, the secret is in making the right choices. If you grab just any turbocharger off the shelf and bolt it onto a motor without putting some thought into it, you’re likely to be disappointed with the results. To keep you on the right path to maximum performance, Holley has teamed up with Garrett to offer a wide array of turbochargers, ranging from OEM style replacement units to all-out race turbos. Along with these, Holley also has the components you need to set up your turbo and get the perfect blend of performance, drivability, and reliability.
The ability of turbochargers to add lots of power is undisputed now, making them essential in many forms of motorsports. Holley and Garrett have teamed up to offer a full range of turbocharger components and accessories, allowing you to easily set up a powerful, reliable turbo system that suits your exact needs.
Garrett has been a leader in turbo technology for nearly 70 years, building turbochargers for every industry that uses them. Along the way, Garrett has helped power racers to victory in some of the world's most demanding motorsports competition, including F1, IndyCar, FIA World Rally, and the 24 Hours of Le Mans. The company’s turbo units have precision balanced impellers for maximum RPMs and minimal vibration, with turbine and compressor housings that are CNC machined for maximum flow and efficiency. This combination of quality and performance makes Garrett turbochargers among the best available today.
To help you get the ideal turbocharger for your needs, the company has now introduced Garrett Boost Adviser, a powerful free online tool that quickly and easily determines the right turbocharger based on key parameters you enter.
It's simple to get started. All you need to do is set up a free account with Garrett – a basic process of entering your email address and a few other bits of information. Once set up, the account lets you use Boost Advisor as much and as often as you'd like. You can also save and recall previous sessions to compare different power combinations.
Choosing a turbo with Boost Advisor begins with entering your target crank horsepower and your engine displacement. This is important because every engine supports a horsepower range (compressor stage) and engine displacement (turbine stage). When entering this information into Boost Advisor, don’t forget to account for parasitic power losses encountered with your vehicle’s drive configuration, or you’ll end up aiming for less horsepower at the wheels than you expected. The Garrett website offers specific guidelines for factoring these losses in.
Garrett Boost Advisor is compatible with mobile and desktop devices. You just have to enter some basic parameters about your engine, how you plan to use it, and how much horsepower you'd like to get out it. Then, with one click, Boost Advisor figures out all the tough stuff for you.
Next you’ll enter how many valves per cylinder, the type of fuel you plan to run, the altitude, engine RPM you want peak power to be at, single or twin turbo, and the ambient air temperature you’ll be typically operating the engine at. Based on this information, Boost Advisor quickly does the complex calculations needed to come up with great recommendations for you to use as a starting point in selecting your ideal turbo setup.
According to Garrett, the maximum power that Boost Advisor states for a given turbocharger is based entirely on choke flow of the compressor map – total turbo capability. This is the potential flywheel power. But the actual results you achieve with a particular turbocharger depend a great deal on the modifications of your vehicle and how you tune and calibrate the setup. For that reason, it’s best to take the recommendations of Boost Advisor and use that as a jumping off point to discuss options with a product representative, who will help you narrow down your selection and get exactly the parts you need for your turbo installation.
Boost Advisor takes a lot of the guesswork out of the process, making it the fast lane for picking the right turbocharger to get your project underway. So don’t wait – get started on your dream turbo setup now!
