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 motorcycles was the Aerocharger. Harley riders loved the Aerocharger’s cutting-edge technology, simple install and lag-free variable vane power. The system was massively popular among riders that needed more horsepower from their EVO engines, and Harley-Davidson motorcycles with Aerochargers 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. And now, after taking an appropriate amount of time off, Aerocharger is back. We’re returning to our Harley-Davidson roots with the release of this turbo kit, featuring the powerful 53 Series Aerocharger turbo for modern EFI Big Twin Engines.
Aerocharger Turbo Systems: the turbo with full H-D pedigree.
Aerocharger Turbo Systems is a 3rd generation engineering company and the manufacturer of the Aerocharger, a specialized Variable Vane Turbo. Aerocharger also researches and develops turbo systems 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.
This turbo kit is compatible with all 2008+ Harley-Davidson FL-Series touring motorcycles. (other models are in development)
The Aerocharger is a unique Variable Vane turbocharger that allows boost response to be set mechanically. Unlike conventional turbos, the Aerocharger can create boost without any turbo lag, which makes power exceptionally smooth and available on demand. A smooth power band means there aren’t any dangerous surges or jolts when control is critical.
The Aerocharger system is the best system for motorcycle ridability, whether out on the salt flats or climbing up long mountain highway passes. Peak power is made around 4500 RPM, but peak torque comes on at 2000 RPM. Low-end grunt in traffic is critical for Harley riders, and the Aerocharger produces torque that blows away conventional turbo kits. Huge low-end torque makes it the best turbo for merging on highways, getting around slow traffic on steep grades, or rapidly getting up to speed from a dead stop at traffic lights.
The Aerocharger system has been designed to run on standard 91+ Octane pump fuel. Higher octane fuels can be used for better performance, and are recommended when the system is set for high boost.
The Aerocharger 53 Series is an extremely efficient turbo under normal cruising conditions. Gas mileage can be affected depending on boost setting and riding style.
Boost level is mechanically set by a pre-loaded spring inside the Aerocharger’s integrated boost controller.
The 53 Series Aerocharger ships pre-set for 5 PSI boost, with an 8 PSI upgrade spring also included. The Aerocharger’s bearings are exceptionally efficient and allow more horsepower to be produced per pound of boost than conventional turbos.
The Aerocharger system is compatible with most engine mods, such as built engines and upgraded cams. High compression pistons will require higher octane fuels. If your engine is modified from stock, call an Aerocharger tech to verify compatibility.
The Aerocharger system includes a muffler assembly, which is similar to typical Harley exhaust systems in noise and exhaust note. A distinct turbo Blow Off Valve “whoosh” sound will also be audible.
Reliability And Support
Many turbo’d Harley-Davidsons run Aerochargers, and riders often report getting 100,000+ miles from their original Aerocharger systems on bone stock engines. The Aerocharger system has been heavily tested and the fuel control is solid and predictable.
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.
No permanent modification to the motorcycle is required, and the system can be uninstalled from the vehicle to return it to stock. The Aerocharger Harley-Davidson system can be installed at home by someone with limited space and normal garage tools. Some Aerocharger customers prefer to have their turbo system installed at a dealership or performance shop – dealers report preferring Aerocharger technology because the systems are properly designed, simplify or eliminate many fail-prone components, and require much less support and maintenance.

AEROCHARGER H-D SYSTEM
Aerocharger’s powerful variable geometry tech optimizes turbine size, producing lag-free boost. Excellent performance for rapid acceleration and high altitude. The ideal turbo for motorcycle applications.
Independent Oil Supply
The Aerocharger contains its own oil supply allowing for clean and fast installation, with reduced risk of complications when riding. This turbo does not require oil lines to be run from the engine, weakening the stock oiling system. It is only necessary to check the oil annually and top off as needed.
An innovative oil misting system allows for drag free bearing performance and ultra-fast spooling. A substantial performance increase over conventional ball-bearing turbochargers.
Sits out of the way for improved efficiency and streamlined looks. Temperature levels are comfortable for passengers, and the mounting location is compatible with common passenger foot boards or pegs.
Robust design allows for best pressurization and smoothest air flow from the turbo. Finished with ceramic coating.
