Dyno results 06 919

I debated whether or not to post this but I am curious to find the variances of dyno results for a stock 919 w/out the pcIII. I had my bike dyno'd this last wedsnday at the local bike night and got some interesting results.

The numbers were a lot higher than I expected. I compared the power curve to that on the jardines website and the curve is practically identical.

The only mods were the bafflectomy and the flapper.

Peak HP was [email protected] rpm
Peak Torque was 74.4 lb/ft @7800 rpm.

Is it common for a dyno to be this far off the reported stock numbers?

Peak HP of 100 @9000
Peak torque of 64 lb/ft @7800

Curious....

I'm no expert, but that seems a bit optimistic. Was it crazy cold out? Was the dyno graph shifted down by 10????

That looks way off to me. Experienced 919 owners have managed to improve the hp of 919 by about 10 or so, but 18 is pretty much unheard of. Are you sure it wasn't the stock 900RR engine?

Seems a bit high for just a bafflectomy and flapper mod, some dyno's are a bit optimistic, but maybe you got a "Good One".

It's common to get variances from shop to shop plus there's the pesky problem of diff in air quality\temp and altitude from place to place. So the dyno is really not a good way to compare these numbers from bike to bike unless they are on the same dyno on the same day. I have a PC3, Satos, & Flapper mod, and i will be lucky if i'm getting 110. When my bike was stock it felt like maybe i was getting 100 horses to the ground.

what you might want to try is tell them that your numbers are way higher than others and you want another run. note the diff in air temp if you get another run and see if the results are diff

she's bone stock w/6200 miles. Interestingly enough I should have persuaded wazzoo to run his as well. we were both there that night and he had just installed his sato's. The next time we go up I will try to get him to run his as well so we can do a comparison. I truly do not think the numbers were correct.

It was about 70 degrees out. didn't ask if the dyno was scaled down though. But then again why would you wanna do that? Another note is that the max speed was 128.5 mph in 4th gear at the rev limiter.

Super 919

I've got an 06 with PC3, Jardine cans, vortex 520 conversion, KN air filter etc... Three weeks ago, I dyno'd at 103-106 HP. Just for reference.



When it was stock... felt like about 100 HP.

That makes sense.... my dyno results seem to be blown up. The only difference that I can account for on paper is that the curve starts at 3200 rpm and shows power levels starting at the 10 hp 25 lb/ft mark, 0-10 has no recordings. Assuming this is the correct. The actual hp should be closer to 108 and torque of 64. But even those numbers are very hopeful.

Does your bike have racing stripes? Those are good for a couple hp.

My wife saw your avatar and thought it was our cat on my bike in our garage.. until I pointed out the tank color. Then she thought it was our cat on your bike in our garage. What kind of cat? Ours is a Chartreux.



Don't blame me for hi-jacking the thread.. I included a picture of my motorcycle.

Maybe this helps? My bike dynoed at 100 HP / 62 lbs Torq in Vegas at 2200 ft elevation and it was 130 °F+ in the dyno booth... Heat kills HP! Had PC3, bafflectomy and flapper done at time.

I ran an 04 without the flaapper, baffelectomised, with a stock map for 3 seasons. I was very impressed with how much faster the bike would get to redline after I put on a set of Satos then remspped the PC3. The baffelectomy sounds nice, but little elce.

My cat is a tabby. And I can see why she would be confused, They both look very similar.

Gray kats are awesome. This is my Mom's cat, fixed and no front claws, but he's been kicking other cats outta the yard for over 15 years, He'll be 16 this spring. Attitude and personality like no other.

I agree. The Satos with one of the maps made by Dan Kyle is the way to go. Bike runs better, harder, faster... sounds great, look great, feels great! Worth the investment as long as you keep the stock cans and sell the slip-ons separately when ya sell the bike. Every eBayer selling stock cans gets a fraction of what they are really worth.. but sell a nice set of Satos and see how fast they get 75% of the new price. Anyway, Satos & a PC3 mapped by DK, the only way to fly!


Oh.. and thanks for the cat pics. Wasn't sure how manly it was posting pictures of my cat .. now I know I am among friends.
