most powerful air cooled dry clutch Ducati motor

[77south]

I feel like I should know the answer to this one off the top of my head, but which version of the 2 valve air cooled dry clutch engines was most powerful in it's stock configuration, and which bikes was they shipped on?  I thought it might have been the motor of the Monster 1100 evo, but that doesn't have a dry clutch.

'12 Hyper 1100 evo claimed 95 HP, dry clutch.

From dyno charts Ive seen, about 4-5 hp difference between the 1100DS and Evo, but the Evo gives up some midrange torque to get the peak number. The dyno numbers were high 80s Vs low 90s.
I have a HM Evo, was glad it has a dry clutch.

Edit: I looked over some dyno charts on the net and wanted to note the torque of the DS1100 motor. The air cooled dry clutch motor with the most sheer grunt would be the 1100DS motor in Monsters, Hypers, etc. One of the chunkiest torque curves around with a very fat pattern on the dyno sheet.

If you want to check out some interesting dyno charts, check out Intake Express in Australia. Their site has a good range of charts for M1100 and HM1100 models.

After a close look at some dyno charts, the restrictive nature of the HM airbox is evident. I suspect the M1100DS airbox (and/or exhaust) are not quite as restrictive. This puts the M1100DS very close to the HM1100Evo, closer than the HM1100DS.
Just some more useless info .
With the same intake mods, the peak 4-5hp difference is more evident.

'12 Hyper 1100 evo claimed 95 HP, dry clutch.

'09 M1100 claimed 95HP, dry clutch.

On the same dyno, dyno chart examples of an M1100DS making as high as 94 and one HM1100DS making as low as 87.
Enjoying examining these dyno charts over a coffee.

Thanks for the responses! That was the information I was looking for.

As a follow up question, would those engines fit in my sport 1000s?
My sport 1000s was bought at what unbeknownst to me was a high water mark in personal finances, and right now, just about the most financially responsible thing I could do would be to sell it. ...But let's imagine I had the financial resources to acquire that engine, because it's better than contemplating my current situation.. would it fit?

The problem wouldnt be the motor as much as the electronics. You're talking siemens on the newer models and marelli on the old. Lots of re-wiring.

[koko64]

Have you seen the Intake Express dyno charts showing how much power can be liberated on the Sport? About 96 sae hp with pipes, tuned PCV and intake mod kit.

I am in no way affiliated with these guys, just impressed with their tuning.

[77south]

Given the electronics issue, and the fact that the power gain wouldn't be that big, it would probably just be cheaper to do a dry clutch conversion on my current motor.

See post on other thread from hnracing. We're speculating whereas he's got experience with this. May want to pm him

[koko64]

That was the Evo/DS 1100 differences thread correct? He has done some great work. Bang for buck comparison between a dry clutch conversion and intake mods with tuning Vs an engine transplant would be interesting. Motors are very expensive down here in comparison.

[koko64]

Hnracing notes in that thread that the early sport had a dry clutch, so maybe those parts might fit.  Worth checking it out. Also, he notes the HM/MTS motors are different at the swingarm. 1100 barrels and pistons can also be fitted.
