Some track Vids (here ya go F8L)
Finally got a couple of the runs downloaded from my video camera. The first one is my 14.4 run last week, and the 2nd one is a 14.3 run from this week. My best is still 14.2.....it was a little humid out today (rain threatening) so that made it a little more difficult. My best 60' today was 1.99 seen in the 2nd video. Wait till the end of the video and notice in the mirror the confused HEMI. He is not sure how he just got whooped by a 7200lb sled...

took a better look at what was going on with my shifting tonight too. Looks like its a good 300' or better before the finish line when i am having to shift up into 4th. I tried letting 2nd and 3rd wind out farther but ended up hitting the rev limiter at 5000rpm. Just not enough gear to wind out enough to stay in 3rd. Looks like my sticking point is goin to be low 14's until i up the pulley or throw smaller tires on.

Sounds good 
Have you talked to the people who tune your truck to see fi they can extend the lower gears out by about 100rpm each so that you dont have to rev that last gear out so much and wont have to up the rev limiter as much? Thats what I did

Are there any mods you can do to raise your redline, even a little? I know nothing about 8.1s, but if it's only one thing that is the bottleneck to, say even 200 rpm faster, it may be worth looking into.

LMAO...it doesnt take much prodding with me. I am leaning towards getting a DMax I/C since it should be a direct bolt-in for my 2500HD. Then all i would have to do is plumb it up. I wonder where i can get a different cast intake to bolt to my manifold? The one whipple provides is directed straight to the blower, I would need one to point the other way. I wonder if Whipple has different intakes to choose from? I know they have different outputs off the blower (depending on if you buy thier I/C or not, the out put off the blower points in a different direction). That would probably cost about the same as a meth kit seeing as you can get a DMax I/C from Ebay shipped for about $150. Those suckers cool the 28+psi generated from the DMax, i would imagine it would have no problem cooling 8-10psi from a gasser.

Isnt there something about the Allison, its not a good idea to spin it over 5k rpms??
I read it somewhere. Because i was wondering why you couldnt change the shift points or Firmness with a Hypercrapper.. My x boss used to have a 04 CCSB 8.1/ally 4x4. I was curious one day and he told me to go take it out for a spin. I manually shifted it, with the rev limiter set to 5800 (IIRC). When it got up to 5500 i bumped it into 2nd and it chirped the 305/75/16 Cooper Dis S/Ts.. WOW.. but then i read about not a good idea to spin the trans over 5k!

Never thought of that.
