Rip harder, ride faster!

When choosing the turbo system for your bike, please consider the following information before you make your purchase.

First, please choose the year range your bike fits into. This is important to ensure you get the correct parts for your bike.

Next, please select if the system will be a Stage 1 or Stage 2 version.

• Stage 1 systems are designed for bikes with stock displacements of 88”–117”. We do not recommend running them on larger displacement motors. Please choose the Stage 2 option.
• Stage 2 systems are designed for the larger displacement, 120” and above. These systems can also be installed on smaller displacements if you plan on building the motor to a larger displacement later. For example, you can install a Stage 2 system on a 114” motor if you plan on making it a 128” in the future.

All Trask Turbo Systems come with the following components: Garrett Turbo Charger, plenum assembly with integrated BOV & 2 Bar Map Sensor, stainless steel header pipe and heat shields, tailpipe for the style of turbo system you are choosing, turbo cam cover, boost gauge & mount, heavy-duty clutch spring, high-flow injectors, NGK spark plugs, hardware kit, and gaskets.

This system does not include a Thundermax ECU. Trask Performance will supply a base map for all newly purchased systems even if you already have a Thundermax installed on your bike.

Not legal for sale or use in the United States on any pollution-controlled motor vehicles.

Please note:

• Twin Cam systems include intercooler (not needed for M8 applications).
• Trask Turbo Systems are not compatible with lower fairings that are not removable, like those on all liquid-cooled models.
• Trask Turbo Systems may not be compatible with all engine guards.
• Lead time may vary depending on the season but typically runs 4-5 weeks once the order is placed.
