    Here is the first dyno run of the TT modded airbox. This bike already had an ECU reflash and K&N filter. Airbox top was just swapped with the stock over to the airbox top I supplied. No tuning was done.

    Below is a text document that shows the gains in raw numbers throughout the the dyno range. Real nice gains everywhere.

    So this isn't even with the reflash tuned for the better breathing, huh? Any ideas what the air/fuel was? It had to have leaned things out.

    Correct.
    I don't have any AFR data but know it was in the safe range still.
    The reflash is biased towards being on the rich side. There was enough fuel to take advantage of the extra air made available.

    Is this two holes will work good with the TT mod and gives more hp or it will make the air escape ?

    I was told that the holes were a Dale Walker mod. I put two in mine before doing the TT mod and left it that way. More air.

    That's right.

    I didn't use that front shroud at all. I had removed that long before the TT mod.

    When I bought a K&N from Jon Cornell to replace the original filter it came with a simple aluminum clamp that allowed you to remove that part.

    So, is it better to remove this cover to make more air comes in ?

    Yea, I think I got a bunch of these in the UFO parts pile (including a bunch of filters). I need to get them out and inventory then get some stuff posted for sale!

    I just completed my Triple Threat yesterday. Tight fit in a couple of spots, especially with the front right stack needing clearance. Now to get everything dialed in with a dyno tune and my PCV.

    Awesome install! Looks great. How did you manage to clear the front right velocity stack while keeping the filters oriented like that? Or have you gotten rid of the velocity stacks?

    I didn't run into a clearance issue on my air box, not sure what was different. It is tight.

    Definitely do not remove the stacks, that would defeat the whole purpose of the modification.

    Here's some pics of what I ran into. I think I may have put the cutouts too far back on the airbox. Regardless, a few cuts with a razor blade did the trick. Excited to get it on the Dyno in the upcoming weeks. I will be sure post some results.

    Ah....thanks. Yeah it's tight in there, just a few mm's one way or another could make the difference.

    I should have done a better job documenting the cutouts with some measurements, but I honestly never thought that so many people would be doing the modification. There is no going back and looking at it at this point, I no longer have the bike.....my current VMax has a sealed air box because it has a blower on it.
