Sure are pretty. They will work with stock air cleaner? | ||
| Easyrider |
Yes, room enough... | ||
| Drawkward |
Those dyno numbers sure do sell your stacks by themselves. If I had the extra cash I'd love to get a set. Good job! | ||
| Aeholton |
Easy - Did you test the longer stacks? I have a set of longer ones from Pasi. | ||
| Avalaugh |
Easyrider, can i buy a set now ? website says not available ? And would it be ok to install with Erik Buell Racing ECM for stock exhaust with K&N. Would like them to be shipped to New York as im going there in 2 weeks to visit family. | ||
| Mountainstorm |
Will the ECM need a recalibration to take advantage of the stacks or is it "Plug and Play"? Nice work! | ||
| Easyrider |
Aeholton, Look here in the article http://www.twinmotorcycles.nl/artikelen.asp?aid=76 you also find the data with the longer stacks, Not a bad product for people who like power under the 8000 RPM, we are thinking about making them also. Avalaugh, we will deliver them after we are back from Bonneville, we have 25 sets ready now. so yes we take orders and you can pay for them, but shipment after the 12th of september I have No experience with the Erik Buell Racing ECM and that calibration. I can't awnser your question without having that ECM in my dyno mounted on the bike with your setup and the stacks to be honest to you, sorry for that. Mountainstorm, I still have to do a lot of testing to give you a awnser, I disable the learning function in the ECM. So I don't know... With our fuelmap it works because we made it for that setup. I also have to make the fuelmasps, ask me this again in oktober, sorry for not having a awnser for you. I do not recommand to use this stack on a stock ECM, because it is ment for a K&N and a good pipe. and the power it delivers, needs a fuel adjustment. | ||
| Avalaugh |
Thats cool, ill put an order in then, but will have to post to the UK as ill be back by then. | ||
| Aeholton |
Easy - One more question. When you refer to open air box, are you referring to open inner air box with the top cover on or both inner air box lid and outer cover off? | ||
| Dannybuell |
Looks great! | ||
| Skntpig |
Doesn't the 1190 have two different sized stacks? Have you tried the same size stacks as E-B-R? | ||
| Easyrider |
This is made for à stock 1125 engine, not for 1190 engine. And yes i tested short long combi's, Front Ans rear swapped, at the end this was the best power for THE money and spread over THE whole powerband i was not looking for racebike top end power you dont use in daily fun and some times circuit riding | ||
| Ratsmc |
Very nice. Glad to see someone made some. They are a little pricey for us here in the US though. | ||
| Froggy |
How will they affect fuel economy? | ||
| Ratsmc |
Froggy, if anything they should increase it. The velocity stacks simply take advantage of the natural harmonics so they are only increasing airpressure at certain RPM ranges. | ||
| Westtx_cr |
I think you should release the longer ones for more low end grunt. I would like them and I suspect I am not the only one. | ||
| Froggy |
Rat that was my guess, but I am not an engineer  | ||
| Strato9r |
Beautiful work, man. A classic hot-rod piece. | ||
| Ratsmc |
Westtx_cr, from my calculations, you'd need really, really long ones to increase low end significantly. | ||
| S1125r |
If I knew those were compatible with the Erik Buell Racing ecm I'd be all over them. | ||
| Cowboytutt |
I started to order some, but the shipping costs were an additional 100 Euros or whatever to the USA. More expensive than the stacks themselves. Too much for 5 hp even if over a broad RPM range. Bummer. -Tutt (Message edited by CowboyTutt on August 13, 2010) | ||

I'm told that's about $130 for shipping milled aircraft aluminum that doesn't weigh very much. Maybe they could ship a batch to Al Leighton at American Sport Bike and save us all some shipping costs. -Tutt | ||
| Puzzled |
Easy what is the shipping to the US and what is the US price? Will you need to "touch up" the Barkers map with these? Will you be bringing any of these over with you? Lets figure out the shipping logistics and I'm in for a set. I'd like to see what they do for me at the track. | ||
| Cowboytutt |
I'm in for a set too, and so is my friend Tym, but only if the shipping costs are reasonable. I'm fairly confident that the Barkers Erik Buell Racing ECM will adjust for the velocity stacks. -Tutt | ||
| Easyrider |
Cowboytutt, there are no orders in my database from last night from you, not even a attempt (-: When you are in our webshop first register, then order your parts, before payment you can choose the shipper, choose TNT and not DHL, shipping cost will be 10 euro then that is about 13 dollar. | ||
| Cowboytutt |
The attempt was made tonight, just minutes ago, and I cancelled it (before creating an account) when I saw the shipping costs. Thanks for the advice, will try again and see how it goes. -Tutt | ||
| Easyrider |
I suggest you Guys, order more then 1 set at a time (-: We will make longer sets also, price will be little expensive then, I started testing with them and if you would read my article in the link above you will find the dyno graphs in the article and the results (-: The longer ones blue line kill HP after 8000 RPM. Look here:  And this is the gain with our version red line:  | ||
| Cowboytutt |
OK Easy, thanks for the tip. Much more reasonable shipping. I think I just placed an order but not sure. Awaiting confirmation by email. -Tutt | ||

Are we dynoing airbox differences or stack differences here? |
