I have a set of Wsbk heads complete, WSBK matched exhaust, Comlete corse intake system and a complete Magneti Marelli SBK kit. Shoot me an email if you want to take out a second mortgage and relieve me of this stuff. I’m not going to use it.

More than that. MM full electronics is close to 20k on its own. Exhaust another 7-10k maybe.

Did you buy the SL frame or is it a SL from start? I assume the last. And isn't these velocity stacks that you have there way to high?
I mean, Jetprimes are way lower:

I bought a couple of SL frames. I built the 1299 SL motor and added most of the F-18 components to it. The intake kit is part of the F-18 RS kit. As far as velocity stack height and shape are concerned, do some reading on the subject. Storm is a pipe mfg. As far as what people tell you regarding head work, I suggest you contact the people who actually do the work and ask them.

I am not familiar with the F-18 RS kit, what is that?
Chill out, I use the term exhaust instead of pipe, never talk about exhausts as pipes, hence the missunderstanding.
Do you have any sources for reading about the velocity stack hight? I assume you don't think Jetprimes short hight is good then.
F-18 is the version of the last V2 SBK from Corse. The F-18 components are a suite of internal and external engine parts made by Ducati Corse. They are not available for purchase. The Jetprime stacks are fine, depending on what your objective is. I chose to use the Corse intake system because it came with the kit. I have about 3k miles on the motor now and it’s amazing.

I see. Not easy getting a hold on these components, did a search for it. How did you get a hold of them (the F-18 components)?
When the teams switched to the V4 the V2 stuff came up for sale through a few channels. I bought what was available. That stuff has all dried up except for a few small pieces here and there. The problem with the Corse parts is that they for the most part are all designed to work together so a lot of parts are not plug and play making things difficult if you buy a piece here and there.

Ah ok that makes sence. What is your current HP numbers on the rear wheel with all of this?
Don’t know. The stock 1299sl on the dyno makes 198-200 on 91 octane. This motor has head work, a lighter crank, lighter wrist pins, different pistons, (CP Carrillo) dynamically balanced, super light flywheel, dry clutch ( less mass) blended intake and exhaust ports. It also has If I had to guess I would put it at 212-215 at the wheel based on the info from Motorapido. Just never had time to get it in a dyno and I really don’t care, HP was not the reason for the build.
The pistons match the SL dome shape but are multi ring and weigh very close to the single ring SL pistons. The weight penalty was more than made up for by the wrist pins. I wanted the reliability, longevity and to maintain low rpm compression that is compromised with the single comp ring.
The motor revs extremely quickly and is noticeably smoother from a dynamic vibration perspective. It also has the Nova gearbox, RS fork kit and gear box drum. Shifts like butter. It is not optimized from a tune perspective. It is “road” tuned for my environment and I am using relatively stock electronics (Tamburini harness, Woolich tune) and it runs open loop (no O2 sensors on the bike)

If you’re in the market, I can put you in touch with someone who might be willing to sell a nicely built 2015 R with a handful of corse parts. Bike made 204 to the wheel on pump gas.

Ah thanks, at this point I am just considering the cost/benefit perspective, and even though I would like these parts, it's just around a 10hp more mod than my bike currently are doing, so not right now, maybe in the future. Thanks anyway

Did you make the pistons and wrist custom, or buy them somewhere? How many rings?
I think it's a very good idea to maintain low rpm compression and going for reliability
I called moto rapido, and you won't get additional 20hp from porting the heads/head work, it only helps a little on top end
By calling around and extrapolating the knowledge from here and there, it is clear to me now that the bigger velocity stacks like yours add more mid range torqe and the lower velocity stacks from jetprime add more on the top end, that is why they can claim a HP increase (3-5). So for my part then I would be looking at higher intake trumpets and not going for the shorter (and very expensive) jetprime ones

Correct, this is well established - for internal combustion engine performance, long intake runners shift the power band to the left, short runners shift to the right.
I’m a bit late on the topic, but I arrived here for the same reason as the OG poster @Vicati
I have a 24 V2, I was interested in the gains from the JetPrime stacks as well since it’s no real data floating around the net. One of my main concerns would be if the stacks would fit on the V2 throttle bodies considering it shares the same airbox housing and V twin/L twin setup as 1199/1299/959.
I read somewhere on here from a post like 6+ years ago that Jetprime tested on Barni Moto Racing SBK Team and says that give + 3H.P. (Listed link below for reference)

After reading through all this vast amount of information, it seems as if people say it’s best to get a better suspension setup and lighter wheels for better performance… which in short sounds nice but that’s $5k+ vs like $900 for some stacks. I don’t think that’s a valid comparison in the slightest. So if anybody has a solid answer if the stacks will work on a V2 and what the gains look like please let me know.

Panigale trumpets
Hello, I've on my Pani a Termignoni Reparto Corse. I changed the Sprint Filter air filter inside the kit with the larger one, the R127SBK, with P16 mesh. I've seen these marvellous trumpets made by Jetprime. Height is 13 mm. Ducati Corse's height is 23 mm. Jetprime tested on Barni Moto...
