Kick •••. I can't wait to see the results  . | ||

hey man were the hell did u get a PROGRAMMABLE ecm? | ||
| Glitch |
Racers get some goodies we can't. Besides, I don't think the programmable one "learns", I think you have to set it up each race for the conditions of said race. Could be wrong, it happened once before, OK twice. | ||
| M1combat |
I would imagine that there's an "easy" way of changing the level of the fuel curve w/o changing the curve itself though. If I had an A/F meter and maybe a little dial to adjust the A/F value it would be a better thing IMO. Granted, the race ECM should be just fine for what we need. | ||
| 420at145mph |
ya probly but with a PROGRAMMABLE one ud think u could adjust the curve like at the LOW end n get a ••• LOAD of more acceleration | ||

Englishman, are we gonna have to guess the makers of the stacks, or will you tell us after the tests? | ||
| Prof_stack |
What's up with the 12 airbox cover in the picture above? It looks, from my monitor anyway, like a whole different kind of cone on the top. Any explanation? | ||
| Stealthxb |
Thats the clear cone developed by the infamous Brion -James team. | ||
| Draoidh |
Its not a XB12 air box, its a XB9 airbox with the vortex cone that goes with the SVVS stack | ||
| Misato |
I think thats the corey james thing, he had a clear top to one of his setups | ||
| M1combat |
That second one is kind of interesting... Does the ID get larger closer to the TB? | ||

GLITCH _ Englishman, are we gonna have to guess the makers of the stacks, or will you tell us after the tests? Actually 2 of the 3 participants have announced their participation either on this board or others. Only one (2nd left in my group picture), has not, but if you know your Buell stuff I don’t think its hard to find where that one came from. The vendors are free to announce who they are here if they wish, otherwise you’ll just have to wait till the end….Oh the excitement 420 - hey man were the hell did u get a PROGRAMMABLE ecm? Glitch is right – Buell has some parts available to racers only and the Prog ECM is one of them. Correct again Glitch, its not self compensating like the Buell Race ECM. What you program is what you get. For the Stack Challenge I will be using the Buell Race ECM we all have access to. I did a dummy run fitting them all this past weekend to make sue I didn’t waste time at the dyno, and took some pics for the report:-    Interesting..... Mark. | ||

from the top pic- we got a stock, hillbilly , coreyjames-SVVS, and ? edited by misato on June 07, 2004 | ||
| M1combat |
So that second one from the left is the hillbilly motors stack? Does the ID get larger as it gets closer to the TB? | ||
| Ortegakid |
I was going to try the cone type k&n, have them in stock for auto applications,will be very interested in results,thx! | ||
| Tucsonxb9s |
Misato, I think the last one may be the carbon fiber piece from Trojan Horse... | ||
| Alex |
@ M1Combat: no, the stack ID does not get larger. You may direct questions about it to me as I designed the prototype and did the flow bench work. @Englishman119: will You use the other systems with air filter and air box top cover? Did You get an instruction sheet for the carbon stack (outer right system in Your first picture) telling You to cut Your stock rubber stack to be used as gasket to air box? | ||
| Gonen60 |
I'm digging the HillBilly setup with the Oven Mitt. can't wait to see all the results.. | ||
| Glitch |
Englishman, could you give my wife a call and let her know I was right twice in a row!  Looking forward to the test results. Thanks again, for testing these for everyone so making an informed decision isn't impossible. | ||
| Englishman119 |
2nd Left System – the inner air box is eliminated completely. ALEX : 2nd Right System – The stock inner air box is retained. However, the air box top has been modified as can be seen in the pic with a revised cone profile (Significantly different to the XB12 cone). The Buell/K&N Race Air Filter will be used. Far Right (Carbon Stack) – Stock XB9 air box will be used + the Buell/K&N Race Air Filter. Yes, there were instructions supplied with the kit explaining how to trim the stock rubber stack top and bottom, to just leave the sealing ring between the air box lower and the stack. Its no big deal, just needs a sharp knife and a little patience. Mark | ||
| M1combat |
Englishman - Would it not make sense to use the 12 airbox lid as it's a very inexpensive upgrade and should be done by all XB9 owners anyway for the far right stack? I'm thinking the hillbilly oven mitt system will win. I don't think there will be enough difference w/ any of them to justify the money spent unless you are on a race track though. | ||

M1 – Although this little project of mine get bigger daily, I’m planning on doing the following to answer some of the email questions and comments I’ve been getting and to satisfy my own curiosity:- Base line pulls will be with Stock Rubber Stack + XB9 lid. Followed by the same test but with XB12 lid – One of the vendors has told me that they tried 3 x XB9 and 3 x XB12 lids with no difference. Another has suggested that the 9 vs 12 lid does make a difference with their stack! Go figure. Where feasible, I will also try the 9 and 12 lid with the systems that use the air box. Right now I’m fitting a shagged race tire on the back wheel. I think all the dyno pulls I’m going to have to do will make the tire look like something off an Electra Glide by the end of the day. Mark | ||
| M1combat |
Thanks for the clarification. Based on the fact that the project gets bigger every day... Is there anything we can do to help? | ||
| Ortegakid |
yea,do you need race tyres?,usually have a few lying around,or? | ||
| Alex |
@Englishman Thanks for answering, Mark. The carbon system I got (the same as Yours) unfortunately came without any instructions. | ||
| Brucelee |
My bet is that any improvements over stock will be marginal at best. Hope I am wrong, but then again, we will all save money. Thanks for doing this work for us. Fascinating. | ||
| Mikep |
Yes, THANK YOU ! ! ! Nice to see a decent try at a fair comparison! mikeyp | ||
| Mikep |
I'm rooting for the XB12 airbox lid on an XB9. mikeyp | ||
| Buckinfubba |
funny the 12 lid worked and showed the diff everytime I dynoed it. it works and I am sure if they released dynos from r&d that would be a given. | ||
| M1combat |
Yeah... If it didn't why would Buell have done it? Personally I think the V-stack challenge will mostly just re-iterate to us all just exactly how brilliant the engineers at Buell really are anyway... If there is any difference to be had I think it'll be from the hillbilly stack (the one with the oven mit) but even then I think with a different filter and a "nippled" cover it would be even better. | ||
| Ortegakid |
M1,that's my bet also,I have filters like that which have an inverted cone inside for velocity,was going to try my own,will await results first! | ||
| Jasonxb12s |
I own a 12 and my airbox lid doesn't look like that one in the picture up top... | ||
| Kds1 |
Jason, That lid you see is a 9 with the Corey James nipple insert.... | ||
| Jasonxb12s |
That would make sense them..Thanks Kev...Oh by the way,,I'm very pleased with the pipe and a lot of other people are as well...thanks.. VROOM | ||
| Xb9er |
The air box lid in the pic up top is not the stock one. It's a modified one done by the those two guys. The pic only shows the stock velocity stack and rubber seal (far left). As posted above: from the top pic left to right: stock, hillbilly, coreyjames-SVVS, and Trojan Horse CF. Mike. | ||
| Buckinfubba |
jason have ya scared that neighbor kid lately...... hey how do I get a job like you | ||
| Slowby |
s&s has used the nipple for years and so have others. it works as to direct the air in better but i cant see a volume increase in the 12 box. the 9 has a taller ceeling above the air cleaner. i see a horse power increase with out the air box cover(not that i like to ride a street bike w/out a filter)and a little more gain w/ the black strip out from the front side of the colored air box lid. i even get more w/the lower removed,and wounder how well the heat resistant mat will do. force makes a plate that just goes over the filter to eliminate the air box cover but is high dollar because of the carbon fiber cover that comes w/ it. any way hats off to you mark and i hope to make tws the 19th, maybe michelle is graduating basic trainning the 11th. but goes to n texas for the rest of the summer. |
