Introducing the Aerocharger Harley-Davidson Turbo System

Aerocharger has a legendary history with Harley-Davidson motorcycles.

From 1994 to 2001, the best selling turbo for Harley-Davidson bikes was the Aerocharger. Harley riders loved the Aerocharger’s sophisticated technology, simplified fitment and lag-free variable vane power. It became a massively popular system for riders that needed more power from their EVO engines, and Harley-Davidson motorcycles fitted with Aerocharger systems numbered in the thousands.

Harley took notice, and an effort was made to partner with Aerocharger as the officially selected turbo for a factory turbo motorcycle. It was known as the “Diablo” project.

“…Harley was unable to forge a supplier agreement with Aerocharger, and an in-house effort to develop it’s own turbo cost millions…but never produced a working product.” -CYCLE WORLD | MAY 2010

As an aftermarket turbo system, it was back to the drawing board. But now after taking an appropriate amount of time off, Aerocharger is back. We’re returning to our Harley-Davidson roots with the release of our Harley Davidson turbo kit for all touring models, featuring the updated 53 Series turbo and refined tuning for modern EFI Big Twin Engines.

Aerocharger Turbo Systems: the turbo with full H-D pedigree.

ABOUT AEROCHARGER

Aerocharger also directly researches and develops turbo systems using the fully optimized Aerocharger for Military, UTV, snowmobile, motorcycle and automotive applications. Aerocharger’s engineers have expert technical backgrounds in fuel management and thermal dynamics, and Aerocharger systems are carefully designed to prioritize efficiency, power and response.

Beta Release


AEROCHARGER H-D BETA RELEASE

Aerocharger is offering a restricted Beta Release of the H-D Turbo System, available now. These systems consist of limited-run components and will be very similar to the production system, and this is an exclusive opportunity to have early access to the new Aerocharger H-D turbo system.

Beta Release Specs

Performance Gains

At stock, a 2012 Harley-Davidson Street Glide dyno’d at 69 hp and 86 ft·lbf torque. After installing the Aerocharger turbo system, and with a completely stock engine running 91 octane pump fuel at 8 psi boost, the same Street Glide registered 125 hp and 137 ft·lbf torque on the dyno. Real world results may vary depending on elevation, fueling and other mods and accessories.

Power Band

The Aerocharger is a Variable Vane turbocharger, and is the only turbo on which boost response can be mechanically set. As such, the power band on an Aerocharged vehicle is similar to the experience of riding a massive naturally aspirated engine – boost is lag free, making power exceptionally smooth and there when you need it. A smooth power band means there is no dangerous surges or jolts in power when control is critical.

Torque

The Aerocharger system is the best system for overall motorcycle ridability, whether on the salt flats or climbing a mountain highway pass. Peak power is made around 4500 RPM, but peak torque comes on at 2000 RPM. Passing ability is a crucial feature for most Harley riders, and the Aerocharger is famous for it’s tractor pull-esque power. Huge low-end torque makes it the ideal turbo for merging on a highway, getting around semis and slow traffic on steep grades, or rapidly getting up to speed from full stop at a traffic light.

Fueling

The Aerocharger system has been designed to run standard 91+ Octane pump fuel. Higher octane fuels can be run for better performance, and are recommended for higher boost settings.

The Aerocharger 53 Series is an extremely efficient turbo under normal cruising conditions. Gas mileage can be slightly affected depending on boost setting and riding style.

Boost Levels

Max boost level is mechanically set by a pre-loaded spring inside the Aerocharger’s integrated boost controller, and aftermarket boost controllers can also be used for additional boost control. See the Aerocharger page for additional information.

The 53 Series Aerocharger ships pre-set for 5 PSI boost, with an included 8 PSI upgrade spring.

Engine Mods

The Aerocharger system is compatible with most engine mods, such as built engines and upgraded cams. High compression pistons will require higher octane fuels – consult an Aerocharger engineer for recommendations based on your specific application.

Operating Volume

The Aerocharger system functions with an included muffler assembly, which is very similar to typical aftermarket Harley exhaust systems in noise level and exhaust note. A distinct Blow Off Valve “whoosh” sound associated with turbochargers will also be audible.

Reliability And Support

Many turbo’d Harley-Davidsons utilize Aerochargers, and riders commonly report getting 100,000+ miles from their original Aerocharger systems. The Aerocharger system has been heavily tested and calibrated, and the fuel control is solid and predictable. This system will offer great performance utilizing the provided Powercommander V, or any other preferred fuel system.

The Aerocharger 53 Series has been OEM and Military tested, and is rated at over 30,000 hours. Aerochargers do not require any more care or maintenance than any other turbocharger, and a properly installed Aerocharger system should outlast the life of your vehicle. We will make sure you have the support you need – for any questions, troubleshooting or maintenance, don’t hesitate to directly contact Aerocharger’s engineers or your nearest Aerocharger dealer.

Installation

No permanent modification to the motorcycle is required, and the system can be removed and easily returned to stock. The Aerocharger Harley-Davidson system is designed so it can be installed at home by a rider with moderate mechanical ability, limited space and common garage tools. Some Aerocharger customers prefer to have their turbo system installed at a dealership or performance shop – dealers report preferring our technology because Aerocharger systems are properly designed and either simplify or eliminate many fail-prone components, thereby requiring much less support and maintenance.
