153 kg & 85 Hp 696

[koko64]

I'm looking at OZ Rapid magazine. 1100 Hypermotard gives a claimed 106 rwhp with 13:1 high comp pistons, DP race cams, porting, Termi 2 into 1 full exhaust system, triple cut valve job, K&N air filter (guessing the kit), Tuneboy reflash.

That's about 20 hp more than stock, but with the pistons and much bigger standard capacity.
My guess is the 696 with the mods stated would be 10 more hp, maybe 15.
Maybe that motor is particularly efficient for it's capacity.
The 696 revs well and has good valve area for it's capacity?

What do the our board pros in the industry think?

From a ducati expert I have spoken to, the valves are very large for the capacity and are at the limit of size for the bore. any bigger and you reduce effeciency.

Regarding the engine mods its a lot more put into it than just grinding a bit.
I know the tuner well and what he does, hes been going his own way all the time and wont listen much to the traditional way to tune, so it will be a unique tuning job for sure.

I dont know about this particular engine but to mention something, very often he makes ports smaller and a different shape to stock although flowing a lot more and so it goes on with just about every aspect and it all adds up.

Understand, but say the engine is 25% efficient, those extra 20HP means the lump has to produce 80HP more and dump 60HP into heat and friction.  The internal parts (bearings) may take the friction and heat, but he should have resized the oil cooler if he wants to ride with that amount of wasted energy. 

[Raux]

well for starters, the 696 doesn't have a stock oilcooler, so safe to say stock isn't pushing the limits of the motor.

I see the point, agree, but mostly in nordic climate it seldom gets too hot, we did an 1123 sport classic that does really well and that one could get a bit hot at summerdays reaching 30 cescius, but it will have an 848 oilcooler along with a ncr one, so its pretty easy to solve. A gauge with oil temp is good anyways  yes.
So of course if you start fiddling you need to know what to change, thats what differ a working concept from the rest.
