Product Description
Have you ever seen or road a turbocharged Harley and thought "I need one of these"? Now you can!! We are proud to announce our bolt on turbo kit for the Harley M8 Models. This kit is built with top quality components at a wallet friendly price. The stock 117 M8 engine puts down on average 100 wheel horsepower on our Axis Dynometer, the Silber Turbo Kit on a completely stock 117 engine, pump gas, 7 psi of boost lays down an impressive 130HP. Install our recommended 465 cam and the HP jumps to 155HP!!! Looking for even more ponies, mix in some fuel additive and throw down 175+HP.
While the turbo kit has been tested and developed on many engine combinations, we recommend that the stock crank balancer be retained or you will risk vibrations causing failures that will not be considered for warranty replacement or repair.
