got some new gtech runs with this lowly 4.8. i took off 108lbs of unneeded weight and have about 60lbs less fuel that before. the first run is from the other day bone stock full weight, the next 3 runs are from tonight. i practiced my launch too, turns out auto4 works best and brake staling it to about 1500 is the quickest, a higher brake stall was slower.

1st run DA was 684feet

2-4 runs DA were 850feet

 

thats right there is power to be made out of a 4.8

 

Does that thing really only weigh 4430lbs?

I think you got a Freak 4.8.

 

no, 4.8s still suck!!!!

 

DAMN MINE WEIGHED 4650 AT THE TRACK SCALES AT HRP.
ALL I HAD WAS AN EMPTY ALUMINUM TOOL BOX IN THE BACK, AND ITS A STEPSIDE

 

i have no idea what it weighs, that is the stated curb weight. the weight that i enter doesn't effect the ET but it does make the hp and tq read low. thats ok with me.

 

Looks like those 03 4.8's can really move.

 

got another one for ya, this is a screen of g force vs time, you can see both shifts clearly. if the shift points were correct you wouldn't be able to see the loss of RWTQ, when i can adjust that it should get a litte quicker.

 

keep in mind people... this is a z71

 

...so that should mean that it weighs more and is slower because it has skid plates and heavier jounce bumpers

or maybe I just missed the sarcasm
