I wonder at what speeds going to a larger snorkel would be beneficial, even if it did end up sacrificing drive through the gears. Also since we had good tailwinds for most of Sunday, would one necessarily deduct 10+ mph from trap speed to determine what speed air was hitting the snorkel?
Good point on the tail wind.
As Doug pointed out, the area only increases volume not pressure. So the bigger cc engines would be a prime candidate for a larger CSA inlet.

to smooth out the readings on the sensor with out software try jaming a idle jet from a small cc bike in the sensor line. that is if you have any old skool parts laying around..
Yea that may work. But I was thinking of a small plastic bottle on the end of the tube with a small hole in the end of the bottle. ???

Hey those shifts look pretty crisp, eh? 
Thanks for the read Doug.
Yep, very nice shifts I must say, very nice. 
Doug if you download the free logworks software i can email you all 6 runs and you can see MUCH better the details etc.

Jim, you were explaining to me why it wouldn't work to use the existing sensor in the box, but I forgot the details. Could you elaborate?
Well the MAP sensor is a Manifold Absolute Pressure sensor. It gets its pressure reading from behind the throttle blade.
Its subjected to velocities and pressure waves etc. that are very different from actual "airbox" pressure.
For true airbox pressure you need the sensor to be exposed to the actual airbox pressure

Jim,
Man o' man, these maps are as different as night & day until 10.000rpm+
does yr bike have a DaveO mod'd ECU??
mine is running a ridgeracer mod'd only for revlimit
Yes they are very different. But we have different cams, cam timing, throttle body size, filters for me none for you, and most of all our exhaust systems are totally different. I have the stock (length) rubber velocity stacks, not sure what you are running.
My ECU was modified by RidgeRacer and has the header so I can play internally in the near future and remove the power commander all together. The rev limit is 12,580

Jim-
can you give me a link to the software?

It's not that I think you're dumb, it's just that so much of what you know isn't true....

the green trace on my log is MAP, it always rises pretty much steadily , in the case of Loring from 29.3 to 29.8"Hg.
I would expect it to be more rpm dependent, but it seems once WOT it rises w/rpm (there is no smoothing on that trace)
things that make you go hmmmmmmm

Tom,
good to see you here!
I got hooked w/Chris this weekend; seems he's gonna do a car project next, eh?
Variety is the spice of life. I can't wait to how it turns out.
AND, I can't wait to see what you bring to the Mar Mile!
