"Super Slip-On" Progress Report

Ducati Forum

Help Support Ducati Forum:

All of the dynos I posted were same bike(mine) on the same dyno. The 1198 was a friends bike on the same dyno. I do have a dyno comparing Full Termis on my bike, on this dyno, only change is fueling. The correction factor on the dyno takes into account the air pressure, temperature and humidity then adjusts the numbers to a set atmospheric condition. This way dyno runs done on different days can be compared. The correction factor on both runs were ".99". Its I've tried posting larger pics but my posts are pending approval, so I'll have to wait until I can post pics large enough to read.



Just to be clear, this thread isn't to sell this system. Once we feel it's up to our standards and a top notch product we may offer it to the public depending on demand. Im a consumer just like everyone else. I've had the disappointment of products claiming amazing numbers and they don't produce. With that in mind we wanted to very straight forward with the changes between dyno runs. The only change is the exhaust and bazzaz fuel tuning. I actually used the auto tuner to speed up the process. These results will be repeatable, with proper fuel tuning.

20hp gain for a slip on.

You are achieving more than any other full system.

Do you have an comparisons against Termi/Akra using the same dyne and running it under the same conditions etc.
We are aware! Yes, I'm pretty sure we can get some dyno comparisons to show. The first dyno graph pictured in the original post was of the same bike on the same dyno. Also, "slip on" is a loose term... 75-80% of the system was re-engineered.
I would really like to see some comparisons on the same dyno. 20HP at the wheel is a huge gain.

We are aware of the large power gains with this unit (roughly 13% at the wheel in the mid range).

I would like to clarify a few things here, call it "food for thought": First understand that this is NOT a knock on any other system currently available. Most of them are quite nice! But, unless you truly take the time to tune and target a certain rpm range through pressure wave tuning, then the gains will usually be moderated. As "Nic" touched on earlier, there is a LOT to consider when developing a true "tuned" system. The whole reason for us developing this system was because we were not happy with what was currently available. 3%, 5% etc top end gains look nice on a dyno and do supply more power up there but its not as "usable". For us, it was important to gain as much usable hp as possible without sacrificing the fantastic 1199 top end. The exhaust system we built was SPECIFICALLY made to make power where it has.

The truth is, if one was to remove the factory muffler/cat and make the exact oem exhaust system with larger piping, it WILL make more hp. Albeit mainly top end... This is because the area where maximum flow is required is being targeted. In order to make a system that does "more", a lot needs to be figured and tested ie, pipe diameters, steps, primary length, collector location, tail length, overall length, bends, egts, steps and the muffler, to name a few. This is why we are having this design patented, because of the specifics of this unit!

I hope that answered some of your questions. Please feel free to ask any other you may have!

i have a 1199r with a blueprinted engine and full akra with a tune and my dyno graphs look very similar so maybe i should i saved my money:),

my 1098r dyno graphs are also very similar but you are generating more top end hp on your dyno which does not seem right

Looking forward to seeing this when it's complete and it can be compared with the competition

It looks very similar to my full Termi system with PCV and Autotune (you are just using Bazzaz). B|

The peak number is the same but I'd bet the midrange is stronger. It's difficult to compare because your dyno is set over time. I could post one over time but gearing and tire diameter will be a variable.
 
Actually we do! We are looking for a third party to install, tune and post the results. We only have one kit so it'll have to be on loan.

The three older runs was when I had the standard, but powerkoated manifold refitted (after her accident) and the CW slip on (with PCV and Autotune).
The latest run was with her full (modified Termi's - also powerkoated inside and out) with PCV and Autotune. When I take her in again the power curve should look even better as more of the Autotune magic will be present, but you will see my midrange is at all places quite a bit superior to the standard (with CW slip on) midrange where the normal full Termi setup would actually be lower in a place or two. :cool:
 
For a better comparison your dyno would have to be over engine speed. Great numbers btw!
 
I read most of the thread, and I was quite hesitant on commenting this one. :)

I kind like the exhaust, from the design point of view. But for that matter I also liked the AR exhaust and the way they blended it with the bike, by adding new belly pan.

Hope you don't be offended by my next comment, and it is only my opinion and I have no itention to flame or bashing. So here it goes.

IMO the the superbikes engines nowadays are very optimized. The age of more then 10hp slip-on/full system are long gone, IMO. So, I think that your numbers are a bit to optimistic.

Sorry about my english, and I hope I have not been misunderstood.

I agree with you that large gains are much harder to come by now. But the factory is having to deal with noise and emission laws. Hopefully we will have numbers from a second bike soon.

No offense taken! And I agree with you to a point... but you need to remember, the oem stuff has to comply with the laws, noise limits, emissions, packaging constraints etc. Like I said in a previous post, "if one was to remove the oem system and replace it with an identical one, using larger piping and no mufflers, it WILL make more power". This is because of the "restrictions" that ducati had to follow as "oem engineers". Ask yourself what the goal was for the 1199? Well, there were quite a few, but it was mainly the top end power output. And they succeeded in that. But our goals are slightly different from that. There is definitely power left on the table all throughout the powerband, you just need to take the time to find it!

Please explain the bit "For a better comparison your dyno would have to be over engine speed" as I am not sure what you mean by that? :confused:

hence the mod with the de-cat and the db-killer bypass ;)

still too heavy.

i'd really like to see the akra slip-on, if they followed the internal OEM design or what they came up with...

props to you guys, i think your black mamba exhaust is awesome!
 
I will talk to Alain from Dynojet, but I was always under the impression that the horizontal scale represents engine revolutions.
 
The horizontal scale is normally engine speed but on your dyno it was time. Time scale is helpful to see how much faster your engine is accelerating after mods. Another tuning tool. Your shop would need to change the X axis to engine speed and reprint the dyno. No need to dyno the bike again.

This should help with deciphering the dyno graph!
