Assuming ~200hp final you are looking at 20-40hp, or ~15k-30k watts, FJR1300 gross power generation is what, like ~600 watts at ~5k RPMs if I remember correctly? So no.Plumbing a direct turbocharger without an intercooler wouldnt be difficult for any halfway decent fabricator, especially if you were not highly concerned with looks. With modern decent quality small turbo producing moderate boost on a 1.3L i4 you could set that up for minimal turbo lag.Hard part would be the engine management, unless you could bring the bike to someone who was capable of very granularly modifying the ECU tune and could dyno tune it for you, you would be looking at a standalone ECU solution like a megasquirt install and turn from the ground up. All that is assuming nothing internal needs to be done, and FJR1300 rods dont look incredibly robust...</blockquote>
