Depends on what state of tune you are able to achieve. ECU upgrade, heads flowed, valves waisted, HC pistons, titanium rods, airbox mods, blueprinted motor, lightened and balanced crank, flywheel lightened and balanced. cams dialled in, new cams, exhaust system change etc etc.
if the engine is in good condition you do a before and after on the same dyne and at the same time conditions as near as, that way you will see the increase rather than a number pie in the sky......
it would be cool but would nees a complete exhaust rethink to link both cylinders into 1 turbo manifold and create holy hell with the fairing...... much easier imho to go twin turbo ;-)
CJS did mine. DP flash with slipon Akros 131. Post CJS treatment with ingintion set up 139. Same day, all day. Torque also increased by a couple but 5 in mid range and generally same across the whole rev range
Anything is possible Best option buy a 1098 motor and chuck that in there. Cheaper and more reliable.
The 140bhp is just the claim from Ducati and appears to be high. 130 at the wheel seems to be more accurate for a Termi'd bike with ECU and filter. An extra 20bhp is a lot!
