I made 8 runs at the Houston Raceway Park on Sunday with eric the head (he was on his bike though).
I averaged around 15.5 sec @ 87.5 mph, with my best 15.485 @ 88.69 mph (shown below). Not bad for a big 4x4 truck with BFG's, but for some reason it always feels faster around town. Guess that's how it always is.
Still, I beat a stock '04 Ford F150 CC 4x2 w/ tow package He said his best was 15.85 sec.
I tried multiple launch techniques, and here is my opinion of the different ones:
1) power brake launch at 2500 - 3000 rpm: too much wheel spin. gained about 1 sec on my average time.
2) power brake launch at 1500 - 2000 rpm: what i used to get my average time; about the same results as a normal stop-light launch.
3) regular launch (punch and go): the way i got my best time.
4) regular launch w/ manual trans mode: slow shifts, gained about 1 sec on my average time.
I also checked my weight on the scales. Said I weighed 5520 lbs WITHOUT me in the truck. My cargo: subwoofer & bandpass box (~40 lbs), 24 pack of water (~25 lbs). That weight seems too high (about 300 lbs too much), even for 4x4 w/ offroad.
Scales could have been off.
Current Mods:
Exhaust: 2 1/2" tubing all the way, Husker X-pipe before the muffler, Flowmaster 50 series (dual in / dual out)
Intake: Fram Air Hog high-flow drop-in filter, stock air box mod (shortened snorkel)
Suspension: Superior Helper Springs for rear leaf springs.

Thanks for posting all this Titan4x4Aggie
Nice runs, 5220lbs, that's more than I thought.
I know the manual says don't go above 55 or somewhere close( I can't remember exactly) would you make a run in 4wd or is wheel spin not THAT much of an issue for you. It is for me.
I'm wondering why heads times are faster than yours ( hi 14's) with no NOS and being he has a CC which I would think weighs more. Mods maybe?
Thanks for describing all your launch technique. When I go I'll have a heads up( no pun intended
)...
