Akrapovic Full System Dyno Chart

Ducati Forum

Help Support Ducati Forum:

I have a Panigale with full Akrapovic system on the dyno at the moment.
I am making a custom TuneBoy map for this as I think the Akrapovic system will be popular once people see the results.
I was a little sceptical of the dyno graph posted at the start of this thread.
The bike I have on the dyno has very good performance in the midrange.
I will post the dyno results when I am done.
I will post the graphs showing power delivery at several points through the throttle range.
I don't have before runs for this bike because I aborted the run when the A/F ratio hit 16/1 on the first power run.
I do have a dyno graph of the AR exhaust and I will post the tuned AR system and tuned Akrapovic system as a comparison.
I am also fitting a strain gauge quick shift to this bike, this adds the throttle blip on down shifts.

Could you also please post a video of it in action? I feel like this exhaust is like a frickin unicorn when it comes to seeing it. All of the vids on YouTube are horrible quality (except the ones antihero posted, but they were short). A lot of members including myself would very much Appreciate it!
 
I will make the map available.
The normal maps we provide are based on the Ducati fuel maps and you apply a trim file on top.
With this map I am changing the base numbers so this bike will have a zero trim on top.
This method take longer but it will provide a good base map for anyone with the Akrapovic system.
This next screen shot shows the before and after at 38% throttle.
I had added 15% over the entire range and it still hit 16/1 A/F in midrange.
The two red lines are the A/F ratio for front and rear cylinders (with 15% added).
The two blue lines are the front and rear A/F after tuning.
Tuning this throttle row took 2 minutes.

This next image shows the bike on the dyno.
You can see the wide band O2 sensors and the heat protection to stop the hugger melting (Bike is pulled down on dyno so the rear exhaust hoop is closer to hugger)

I notice you have stock rear-sets. If you replace those with Lightechs, you should see a 10-15% increase in HP for your dyno results.
 
I know what you mean about the Unicorn.
When you look at the workmanship in the Akrapovic system you can see why it took some time to come to market.
A work of art...
A nice sound.
Good performance.
 
i'm really leaning towards getting an akra at this point, meaning some termi slip ons will be for sale shortly.
 
My full termi's will be for sale as early as next week when I have time to put on my Akras.
 
Tuning is complete.
Max power is 190.
All I have left to do is to find the throttle points that make the most power at the mid RPM points.
My dyno shows HP even when holding at a fixed RPM.
I hold the bike at an RPM point then turn the throttle until the power peaks and starts to drop, I then back off to the point that makes the most power for that RPM point. I note down the actual butterfly % open.
I repeat this at the points between 5000 and 8500.
Once I have this data I modify the throttle tables so that these throttle points are what you get when you open the throttle fully.
Fully open throttle plates do not give the highest power in the midrange.

The exhaust has turned a very nice blue colour, looks great.

I will prepare some images and dyno graphs and post these later today or tomorrow.
I will do a little video on my iPhone, I doubt that the iPhone microphone will do the bike justice.

thanks, sounds great!!!
 
OK.

Here is a little video I took of the bike on the dyno.
You can see the exhaust has a nice blue colour.
The throttle is being controlled from my laptop with the TuneBoy program.
The dyno we have allows the ramp rate to be controlled, the ramp rate in the video is set to 10 kph/sec, this is why the bike climbs through the revs at a fixed rate. It does not mean the bike is not making power, it means the dyno has to work hard to control the power.

Panigale 1199 with Akrapovic full system on Dyno - YouTube
 
This screen shot shows the gain I made by adjusting the throttle opening (Explained above).

You can see I have made some nice gains between 4000 and 8000 RPM.
I was surprised how much the throttle needed to be closed to find the best power (when compared to the Termi full system).
Some points moved back from 70% to 58% throttle opening.
 
Now the good bit, the comparison.

This first graph shows the HP on a standard Panigale vs the Akrapovic Panigale.
I didn't run the standard bike to the limiter because it only had 2000 km on it.

Now the torque

This next graph shows the Akrapovic system compared to the AR system we tuned on our dyno.

And Torque (Akra vs AR).

I don't think any words are required...
 
Wayne - Given that the akra geometry at least visually looks so similar to the termis, can you explain what enables it to fill the torque valley? Genuinly curious how akra engineers were able to figure this out when termi/ducati wasn't
 
thanks for this the results are really impressive especially down the lower rev ranges it really gets rid of those flat spots.

For the max HP graph is that comparing the stock exhaust v's the Akra or the AR V's the Akra.

thanks again for posting this
 
Stock vs Akra was the 176 v 191

AR vs Akra both made 191 but Akra filled in the hole, it also did not make my ears bleed.


As for how Akra have filled the hole ??
I think you would need to cut the muffler open to answer that question.
Perhaps the path through the muffler simulates a long secondary pipe and short muffler.

As I said at the beginning I was sceptical, not any more.

cut it, cut it!!! ;)

i guess it's quite similar to the termignoni, in order to achieve the torque it requires length, and for top end it requires the ability to breathe. so a good compromise of both...
 
impressive results. anyone that was on the fence should be able to make a decision. now if only the price was reduced...
