With the mods my truck has -4.10's and truetrac my truck ran 15.8, last night I ran w/4.10's and truetrac and only went 15.6. Also my speed dropped 3mph w/4.10's going from 3.23. It was 15-20 degrees warmer last night than it was last week. Here is a picture of my intake setup http://www.ls1truck.com/upload/files...trip%20016.JPG . last night after the race I felt my filter and it was hot, could this have allowed me to not gain what I should have(.5-.8tenths instead of .2)I can get a CAI from latemodelrestoration.com for $100 shipped should I invest?
Thanx in advance for all replies!

gears are usually 2-3 tenths

your air intake isnt helping you one bit. your better off with factory box

warmer temps slow down vehicles, DA factor, elevation and etc play huge roles in racing

also if computer wasnt programed for the gear change then that also can play a small role in your situation

Agree the intake setup is ghetto, but the times still sound about right for the mods you have.

i never had mine retuned for the gears, what kind of difference are we lookin at? wondering if that why my truck likes to lug the gears around town.

Thanx guyz, I guess I was overhoping this 4.8. I'm pretty sure i'm gettin that CAI soon.

Thats not a bad time for what you have done. The problem is all the 17 second ricers run around saying they pull 12's or 13's that have never been to the track. So when you actually run at the track you think your time is slow. Get a stall and cam to compliment the gears and you will be happy, for a while, like Jeff said above.

get a cold air intake on there.

I was very close on the estimate. Once you get a stall, headers, and a cam, youll feel a real difference. These things need the supporting mods to make all of them work better. a cam and a stall, you should break into the 13's at like 95-98mph. 15.6 is good for a 4.8. 5.3's with the same mods have ran 15.7's.

I'm actually really close to talking my dad into giving me his wet shot! Which i'm about to start a thread about.

Maybe the rear end is locking up because there is no pinion shim.
