Hi Sonic Duck,

you say that 1198's stock gave 180hp? To my knowledge that was 160 hp for the older ones and 170 for the later. My 2009 1198S (160ph) was software tuned with full Akrapovic to 175hp
My Monster 1200 (no S) has been fitted with 1198 pistons, clutch and cam and now produces 171 hp at 9200 rpm (all @CLUTCH).
Especially around 3000-4000 rpm it is stronger and smoother than the 1198
Limitations of a Monster 1200 compared to an 1198 however are, as I understood from a specialist:
- airbox of an 1198 is less restrictive and will always give more possibilities for enhancement
- the intake diameter as well as the injection (throttle bodies) of an 1198 allow for more power

Nevertheless: comparing a 205hp Panigale 1299 power curve with my Monster 1200 learns that:
- at 7700 rpm the Panigale and my Monster are equally strong (140 hp at the clutch)
- above that RPM the Panigale maganes to gain an extra 65 hp when allowed to go to 10500 rpm, mine only an extra 31 hp (171) at 9200 rpm
- below that rpm my Monster has up to 20% MORE torque than the Panigale, mostly around 15% and without the torque dip that the Panigale does have. (you need to go all the way up to 6700 rpm only to regain the torque it has at 4000 rpm, which is 13% below the torque the Monster has at 4000 rpm anyway!
I don't know about you, but I mostly ride it below 8000 rpm and enjoy the almost flat torque curve of 125-133 nm (92-98 lb.ft) between 3700 and 8500 rpm.
I really have no need to find more top end hp as it will surely cost torque and thus hp at lower and midrange revs.

Maybe thanks to the smaller throttle bodies and airbox my Monster is so much better at the rev ranges you mostly use.

Apart from these differences, both the 1200 and Panigale engines are infamous for costly engine failures in continuous race use.
The prolonged rpm's tend to stress these massive pistons to and beyond the limit ... an other reason to love power at lower revs.

Take this with a small grain of salt, but the master mechanic at my dealership and I were having a beer and talking 'for-funzies-mods' with my 1200. He said 1098 cams can drop right in and would net a huge HP increase. He also said (use a bigger grain of salt here) that with enough time and money this engine can make 205 hp. To which my response was O.O
I'd take that comment with a salt mine
HP is a product of RPM and the Testastretta engine doesn't spin as fast as a Superquadro.
Now the Superquadro has been superseded with the Desmosedici engine in the V4 for the same reason.

i dont know how i wound up in this section as i dont own a newer monster, but to answer the OP question, i dont think you have much of a "mod" to the airbox available to you as those bikes have the weird tube air filter. im sure freeing that up will cause your induction noise to go up, but not like an inline 4 on ITBs and stacks

that being said, the induction noise from my S4RS with TPO velocity stacks, a Pipercross filter and HSBK carbon airbox(open) literally causes pain in your ears/head and sometimes causes chest pain and blurred vision. its a lot cooler in theory than in practice. a tucked high load pull in 1-2-3 will often feel like your head is in a vice and cause your vision to go blurry. i have no idea why, and this isnt just me. i have had other people ask me how/why it does that. also, im not sensitive to noise, i spend my days surrounded by heavy equipment and have a VERY powerful stereo in my car.

I did this when having a honda fireblade, velocity stack mod was a simple buy the stacks saw them in half (down the centre) and join them together as then you ended up with 2 short stacks. was much cheaper then buying the HRC spec ones.

Difference meh wouldn't do it again, if bored then go for your life. Put it this way if you think howl is there put your ears out and see if you can hear the difference with someone whom has done the mod.. 9/10 you won't know the difference. power lucky to be 2%

Aussie that is New to Ducati, so im learning new ways from the Japanese 4s
