I purchased a Corse Dynamics velocity stack kit for my EVO SP and thought I would share my experience installing it as well as a review of the differences in performance.

The Corse Dynamics kit is a complete kit. One of the things that sold me about it was the bracket that holds the rear coil and has provisions for both the crankcase breather and idle air filter. To me it is a nice all in one unit that allows for a clean setup underneath the seat. Brackets that hold the front coil to the frame were included as well.

My intentions for installing the stacks were to allow the bike to breath as well as it could in order to accompany the full exhaust and let's be honest, there's really nothing sexy about a bulky airbox on something like this. I wasn't planning on doing this for a while but the kit was on sale and due to the off season, I thought it would be a great little winter project. The longest part was waiting for parts to arrive thanks to drop shipping and places that indicated they had the parts in stock, ready to ship, but really didn't... but I won't go into that here.

This thread here, among others, was especially helpful and a real confidence booster for me before I set out to take the bike apart which I will admit was a bit nerve racking at first because I had never torn a Ducati apart. There were however a couple of very small variations that differed from what the general instructions were but not a big deal and it may be related to it being an EVO, I'm guessing, and has some very slight differences here and there.

1. Instead of having both nipples on the bottom of the air box that simply pulled out of the frame, mine had a screw on the bottom of one that would've been very inconvenient if it had stripped.

2. The idle air breather tube is the same size as the large crankcase breather hose on mine. From what I've seen in all the photos, the idle air tube is smaller, hence the reason for the miniature filter that comes with the kits. Because of this, I had to run an adapter in order to still retain the use of the small filter the bracket is designed for. Again, I'm guessing these minor differences are due to it being an EVO motor and most of the threads and installation info here are in regards to pre 2010 bikes. On a side note, I did not cut either of the hoses and left everything the same length.

Overall, I was impressed with the quality of the all the parts and would recommend the kit 100%. The components are not an embarrassment or understatement to the rest of the bike but I did make a little change and that was to the pod filters. To be frank, I have never really been a fan of K&N filters and it's just a personal preference thing about them. I decided to research what options there were out there for a foam clamp on pod style filter of the same nature and Uni had such thing, only the flange was a bit bigger along with the outside diameter. They had no problem clamping down on the stacks however to make a tight seal. I did not think the left side inner filter was going to fit at first but with some patience, it slipped in and both sit next to each other with no clearance issues from the tank.

My buddy who insisted that he be apart of the project. :)

It took me by surprise after the install when I first I hit the starter button as it immediately fired right on the first stroke. It has never started anywhere near that quickly before, especially when it was cold. At an idle, I could not tell a difference in sound unless I put my ear down near the filters where I could hear a bit of induction. Merely throttling it up did not yield any differences in sound either that I could detect vs. the former open Termi cover. Before we set out on that first test ride report, you're probably asking the question of what kind of tuning/map that I'm running by now, and for good reason. It's a DP ECU with PC-V and Autotuner accessory. While the Autotuner is designed for making adjustments to an existing map and not to be thought of as a substitute to a dyno tune to correct for huge changes such as this, it is keeping the A/F ratios within a safe limit. I did make some minor adjustments to the map for each cylinder, but did not want to make anything too drastic without a dyno. I spoke with my local dyno tuner about arrangements to have him go through it. Now that we've gotten that out of the way, let's get down to it. To say the power took me by surprise the first time would be a complete understatement.

The first thing that I noticed which was more apparent than anything else was the amount of throttle it took to do the same amount of work than it did before. It is completely different. To be totally honest, there was really nowhere that I could get past a quarter of a throttle unless I was asking to go to jail. Seriously. The best way for me to describe it would be like having a quick throttle when it had the airbox vs. now when you roll into near a quarter of a throttle and it feels as though you have the complete full power of the bike unlike before when it took more motion of the throttle to apply that same power. The sensation is like getting transported through time and you had better brace yourself well and have a good grip. Don't get me wrong into thinking that the power is now uncontrollable as it could easily be mistaken for it, no, it is just that the bike makes power with much MUCH less throttle input. I cannot overstate this enough because this to me is most definitely the biggest difference by far. The other very noticeable difference that is second on the list is the lineation of the power curve, which is somewhat related to what I just described. Before with airbox, it felt as though the bike made its power in stages. Picture a staggered power curve on a dyno graph (the airbox setup) vs. a linear curve (the pods) and how the difference of both would feel while riding. Basically the bike feels like it makes the same power everywhere. Back to the sound. From most of the reviews that I've read, I was really expecting the bike to be quite a bit louder with the pods. This was not the case. In the low to mid rpm ranges, I found it hard to detect a difference in fact. It is not until you get it into the upper rpm's and it all of sudden changes from the sound of a Hypermotard into the music of a world class super bike. It is one of those sounds that makes you want to almost cry with joy and I couldn't help but picture myself watching the WSB races on TV. It is unreal and one of those things that must be experienced in order to be appreciated and understood.

All in all I am blown away. Literally. I cannot believe how quickly and fierce this animal is. It is how a Hypermotard should be, but I could not see a stock bike being sold the way that it rides now without an alternative. Unless I want to go to jail, there is no really no way that I could ride it with a heavy wrist on the street. I haven't ridden it in a couple of months due to awful winter weather, but this last ride really made me realize how much this bike is about the experience more than anything. In all of eternity I could not ride it every day because for me, this experience is all about special occasions.

Ducati Enthusiast, glad you are up and running and happy with the result. :D

Drinky, to be honest I do not think that you will benefit from the same sort of performance gain by fitting the MWR lid alone. It is the stacks that really enhance the bikes performance. If you haven't already purchased the lid, perhaps consider investing in stacks with pod filters instead. Stacks in combination with the DP map via Ducatidiag reflash (which I note you are using from previous posts) + trimming the map using ECM software has made a significant difference to my 08 HM1100S. :think:

Good write up, thanks for taking the time. I suppose your filters will do better with our weather up here? I had to run pre-filters quite a bit during the spring months to keep the k&n's from drowning. I love listening to the induction noise as I am blasting around the track, its quite the thing.

Awesome write-up, great to see you're enjoying it
Reviews like these make me want to get the MWR open-lid ASAP, but winter is still going on strong here so I see no real reason to yet ( also mine just hit the service interval so that's gonna have to go first ).
Thanks! I think you'll be very pleased with the results.

From what I understand, the MWR open air lid is a definite upgrade and goes the extra mile versus the "open" Termi lid, but if you want to go all out and get the most that you can, then stacks are the way to go.

You might find this thread interesting discussing both the different setups.

Yeah, foam filters do tend to be more water repellant, especially when they are oiled. I agree 100% with the sound. There is nothing like it and is pure orchestra for me. :)

Welcome to the stack club - Enjoy your stay!

Seriously the change is amazing and what the hyper really needs and if you think the throttle is sensitive now you should fit an electron quick throttle cam...its a blast
Haha,

Well it's very good to be here! :)

I couldn't imagine riding it now with a quick throttle! :eek: That would be one wild ride for sure.

Try a 9 oz. flywheel and a 14 t sprocket too.I do believe the stacks were the most bang for the buck with the exception of the c/s sprocket.

@ Drinky don't buy the puke kit $$$$$ the ducshop kit is a bargain if you don't mind zip ties to hold the coils. around 3 hundo I think . Some of the best money I spent on it so far!

Believe me, I've read almost every thread there is to find about velocity stacks, MWR and the sorts. Now this thread might have got me lucky and I might get to buy the TPO Beast R's from a member here. The most annoying and difficult thing is that most of these stacks are US based. That means it's easy for you guys to get them but for me almost impossible, and if they are shipped here the shipping + import tax screw me over a couple of times as well .
Awesome! That sounds very promising about the 'R stacks. Hope that it works out for you and will be looking forward to your ride report! :)

We'll see what happens, the weather still has to clear up here first
I know what you mean 100%. It still won't be another 2 months at least before we see anything decent around here in terms of riding weather.

But all these threads do make me excited about getting a performance mod (since the Hyper is the first bike I found worthy to keep and mod). With the stock airbox and DP lid (and DP ecu, 2-2 termi's and LV decat) I'm already churning out pretty good figures, but it could be even better .
I definitely agree on all accounts. :)

Thanks for writing that up. I just did the same mod right before I saw your post. I havnt got a computer yet. As I travel through different elevations frequently I have decided to go the route of a power commander instead of a computer with just one map.

My 2010 evo sp runs a lot smoother. As you said the biggest difference is the throttle response. Before I always had to shift before what felt like the peak, now it feels so smooth through each gear. I also took the baffles out of my stock exhaust until I can get an aftermarket pipe. (added a cat eliminator as well).

Also It takes much less effort to can wheelie now :)
 
#12 ·
Good to hear you got the same results!

I guess that it really shows how restrictive the air box is to the performance and ease of rideability like you mentioned.
 
#13 · (Edited)
Well it seems like I'm getting the stacks. Ducati Enthusiast, do you know the size for the 2 small filters (breather and the other one)? I'm not sure if it's 9mm, 12mm or 18mm for the breather and don't know the small one.

Also, I think the Beast R is the same sizewise as your stack, which uni filter did you end up getting?
 
#14 ·
Hey Drinky,

That's great to here! So glad that it worked out for you. :cool:

I unfortunately don't have the packaging for the small K&N filters came in the kit anymore so I cannot supply to you the part #'s or MM's of them off hand. I would recommend contacting Corse Dynamics as they should be able to provide it. I actually contacted them with a question about the large K&N filters soon after I purchased the kit and within minutes, received a prompt response back. Here is the link to their contact form: Contact Us - Corse Dynamics

The UNI filters that I used are part #: UP6350ST. If you do go that route, just keep in mind the left side takes a lot of patience to squeeze in, but it will go. :cool:
 
#16 ·
Awesome! Definitely keep us updated.

I agree with your thoughts about the foam filters.
 
#18 ·
Thanks!

I did make a few minor adjustments to the current map, but nothing too crazy without a dyno. I've been monitoring the A/F ratios and the Autotuner has been keeping them within safe limits. I need to at some point get it in for a proper retune with my dyno tuner.

Haha, nope, don't have any worries about Duke drinking on the job! :cool:
 
#19 ·
I have been convinced into ordering the stacks... along with the decat pipe... and a soon to follow Lofgren tune. My sole purpose is to avenge the theft of my beloved Hyper S...





And to impress the chicks of course, I loves me the ladies.:D And maybe fight crime if I'm not too busy doing the other two, don't want to overbook myself.

Results soon to follow.... Thanks frienemy:D

Right on!! :) You won't be dissapointed.

Looking forward to your write up! Congrats!

So after a while of calling and mailing with a manufacturer of foam filters in the UK I was able to get them to make custom foam filters with my specs. At first I thought costs would skyrocket since it's a custom job, but it would cost the same as the Uni filters with the too big ID.

Better yet, the specs are pretty close to the K&N pods. For future reference and anyone using the search in the future, here are the specs for the filters I'm having manufactured:

Neck ID: 82mm (this will clamp down fine to 80mm)
Outside Base Diameter: 122mm
Top Diameter: 90mm
Filter body height: 152mm
Neck: 25mm

If all goes well, they should arrive by the end of next week. Can't wait to see if these improve the performance or not.

The bike is currently set up too rich, but it's very smooth throughout the powerband. No hickups, no dips, just a straight pull from 3k rpm to redline. Exhaust sound is quite deafening as is, so hopefully the intake noise will counter that by being even louder :D .
 
#22 ·
Nice! That's fantastic news, this will be a great option for other folks who would like different a avenue vs having to use the K&N's.

Looking forward to seeing them and great job putting all of it into motion. :cool:

I just realized I might've made a mistake with the filter body height. I thought it was the total filter height, but it seems like you have to add the height of the flange in there as well to get to the total height.

I've asked to manufacturer to adjust it down a bit if it's still not produced and if not I will just have to hope that there is still an extra 20~25mm of room to spare.

Such a stupid mistake :rolleyes:

Drinky, try a saucepan with boiling water, dip the plastic pod ends into it until they go nice and soft. That is how I got them onto the stacks.

A couple of drops of dish washing liquid will help too.

Once the water has dried the soap doesn't provide any lubrication. This is the same technique shops use for fitting throttle grips.

Sorry to dig back up this old thread, but I too just put these stacks on and I wanted to piggy back off your review and give my own. First impression was sheer excitement. Looking at the two new gigantic cone filters and thinking about how much more air the motor was going to draw in was what did it. The install was not difficult by any means. I had to reread a few things here and there. I was dissapointed that they didnt send instructions with the kit. I had to print them off their website. I mean come on you couldn't print out 4 pages and put them in with the kit? Just kind of struck me as cheap or lazy, but hey maybe they want to save the trees. The entire install took 2-3 hours, but I'm sure could be done in less than an hour and a half. Like the OP said taking off the tank is not necessary just prop it up.

First impressions riding. The first time I got the front up in 2nd and heard that glorious growl of the intake I smiled real wide. I was not prepared for how good it sounds. The sound is not there at idle and not really when you're cruising, but hit the throttle and the sound will only get more intense and ferocious. All throughout rev range feels smoother. I'm sure it added some power and with tuning can make a bigger difference, but my butt dyno isn't picking up on anything major at this time. I was also having a lot of popping recently when letting off the throttle. This is because I shortened my termi muffler by a lot. Adding the stacks seems t have taken care of the popping problem. Not totally, but it's a noticeable decrease.

For anyone thinking about doing this I will leave you with this. The only things you actually need from Corse are the stacks, that's it. Everything else you can either buy or make do without. So if you get a chance to buy a couple velocity stacks by themselves DO IT then buy the 2 cone air filters and the other two smaller filters. You will definitely save money. You will have to do some ******* engineering in regards to finding new places for the coils, but it's really not a huge deal. All in all I am happy I did it and I can't wait to get it all tuned.

Thanks for the review, Ken!

It sounds like we both share similar observations. :cool:
 
#33 ·
Got it, thanks Kenan. :)

The PC5 and Autotune were already on the bike when I bought it so I unfortunately don't have experience with them not installed on this particular bike.

I haven't had it dyno tuned yet.
