Call to Order
These new Trask Harley Turbo Kits were originally designed and produced exclusively for our ASSAULT Series Bikes. ASSAULT Turbo Kits will give an aggressive, combative and militaristic look and feel to any Harley-Davidson, while providing you with Monster Power Gains! The ASSAULT Turbo Kits all utilize an external wastegate setup.
TRASK Turbo Kits will boost the power on your Harley Davidson motorcycle about 40-50% more horsepower to the rear wheel! Our Harley Turbo kits are 100% bolt on and do not require any modifications to your stock engine when running 8lbs of boost on 91 octane pump fuel. Our turbo systems make peak HP and TQ right where you need it, between 3,000 and 4,000 RPM. For Monster gains our kits are capable of making 120-300 HP to the rear wheel (depending on engine size, fuel quality, Stage 1 or Stage 2 kit, & application). Application is everything, turning up the boost means engine upgrades may be required. All Trask Turbo Kits require the use of a Thundermax ECM which is purchased separately. Trask can provide the Thundermax with your turbo kit preloaded with the proper base map.
