I dyno´ed my 999R today. 153,5 HP at the crankshaft.
It has a 57mm Termi system, a reflashed DP ECU and big valves with done ports.
My buddies 999S 06 made 152 HP bone stock... did all 04 999R have some kind of low power? I was a little surprised to be honest. I expected something like 158-160 with big valves and 152-155 stock.
Also - my machine is running quite hot. On the dyno we could make one run at 80°C. Then the temp went up to above 100 when the fans kicked in. The dyno guy let it run in neutral for a while with the dyno fans running, but it didn´t cool down very fast. After two minutes it cooled down to like 98°C.
After that I test rode it on the street in 1st and 2nd gear a few hundred meters. It never got below 100°C. Sure, I don´t have the full cooling wind that I would have on the track. But still, isn´t that a bit odd/hot? I lost 5 HP from the first 80° dyo run to the 2nd 100° run. I hate losing power...

Any ideas?
The older 999r did not make much more power than a 998s. The new 999r has bigger valves/more compression and higher lifting cams as standard.
It is possible to get the older bike to make good power but the heads need to be done right so does the camtiming.
On our dyno 998s 100mm bore makes 133
999r makes 136
new 999r makes 142
With your 104mm bore and heads i would have liked to have seen 145-148 without pistons. The new 999r can pull 160 or more fully built on race gas (i know marc from ducshop did one here think it belongs to trussdude)

The P4 Ammerschläger dyno measures at the engine, not at the rear wheel.
not to pick nits but the dyno must calculate crank horse power unless the engine is in fact out of the motorcycle . Losses in the final drive and transmission and tire to road must be calculated out in order to get crank horse/power. True crank horse power is measured in a test cell where power is measured from the crank.
My real reason for asking was to find out what the calculation was for friction loss. MY Guess ....In your case they would be adding something around 15% to whatever was measured at the rear wheel.
it is normal for Ducati to give crank horse/power for their engines ,these numbers are always larger than what can be observed in real world testing where friction losses are part of the picture. Crank horse/power in your case only has meaning if you know what amount was added to the measured horse/power.
point taken Tom ...I was trying to point out that it's ridiculous to quote crank horse/power when the readings are taken off the rear wheel .That is unless the dyno guy is trying to give the impression that the bike makes more power than it does.
Ben check out the cooling system on that bike.
Never getting below 100º C on the street is not usual
I checked it out this weekend at the Lausitzring.
During the warm ups and the races I had roughly 90°C, maybe a bit more sometimes. Not perfect, but ok so far I think.
The engine feels great, has a lot of midrange power. Here´s the dyno graph by the way, just for you guys who are interested.
I ran against some guys from Denmark, who had Jason(?) Hackett from JHP build their 999R with 1098 crank and pistons. Unbelievable, how much power they got out of that engine. We have 2 guys in the series running that setup and both have around 180-186 HP at the engine. Nice, but they were a slight bit slower during the race. Seems like they couldn´t handle the power all too well. Anyway, I´m getting carried away...
Interesting read! I'm happy with the ballpark HP that my 999S makes. Enough to scare the piss out of me.
My 04 999S makes around 145+ crank HP with a few mods and it does the same to me. The machine is plenty fast enough for what I do. I just started riding the bike after a long lay off, impressive power.
