Trask Tornado Stage 2 Turbo Kit Gen 1 - '17-'25 M8 Models

A complete Stage 2 turbocharger system for 117 cubic inch and larger Milwaukee-Eight motors.

Trask built the Tornado Stage 2 to take a Milwaukee-Eight well past what any bolt on exhaust and intake can reach. A larger turbocharger, a matched tailpipe and a plenum with an integrated blow off valve turn a 117 cubic inch Harley-Davidson bagger or Softail into a genuine 200 horsepower motorcycle. Everything needed for the install ships in the box.
