another new ET and it's a good one
i ran a 12.90!! <img border="0" alt="[gruffy cottonball]" title="" src="graemlins/gr_gruffy.gif" /> <img border="0" alt="[gruffy cottonball]" title="" src="graemlins/gr_gruffy.gif" /> <img border="0" alt="[gruffy cottonball]" title="" src="graemlins/gr_gruffy.gif" /> i am going to go thru my last 2 days of runs just in case anyone is interested. i ran one 13.04 yesterday but it looks like it may have been a fluke cause all the others at that time were more like 13.2 so i will leave that one out.
previous best of 13.39 with full weight and 6psi pully
1. add fuel pump, injectors, exhaust cross over, eaton, 02's .96 or so, 13.48
2. bbk, turn down torsion bars and cold(20deg), 02's .96 or so and droping fuel presure at top of 2nd, 13.24
3. drop 5% fuel from above and all the rest the same, 13.26
4. air box mods, 20deg again, boost actualy went up to 7psi so the air box mods must have been needed, 02's still .96 or so and still runing out of fuel(droped from 62psi down to 45psi), 13.14
5. drop 5% more fuel, 02's around .94-95, fuel presure barely diped, 13.02
6. drop 5% more fuel, 02's around .93-.94, fuel presure stayed steady, 12.90
my 60' were from 1.83 to 1.85 for all runs and my 0-60mph on the last run was a 4.22sec finialy got me a 12sec ET and i am prety happy to do it with full weight and only 7psi, with wideband tuning there may be more, maf peeked out at 52lb's.
i am amazed at how much of a diference there is between a 13.48 and a 12.90, one feels slow and one feels fast. i see mid 12's in my future, very curious to see how hard it is to run good times in the summer.

Re: another new ET and it's a good one
Just a few questions,
Is .9xx a little rich for a charged engine?
have you removed TqM?
Are you seeing any effects of cat overtemp?
What are you going to do about the maxed out maf?
Where did you adjust the 5% fuel at, table?
Good time btw, i bet that looks awesome seeing a big truck going down the track that fast.
Hopefully this year sometime i'll be with you in the mid 12's. i know traction and NOS would get me there, but i need $$$'s.
seeya,
allen

Re: another new ET and it's a good one
allen,
not really sure if it is rich or not, got a wideband o2 coming soon so i will let you know on that one.
TM is long gone
don't know about the cat over temp feature, maybe the wideband will tell me.
from what i understand they dont max out till 58lb's then there is something you can do to get you by to 63 or so. i will worry about that when/if i get there.
pulled fuel from the PE vs rmp table, i had added it awhile back, i am close to stock settings now.
traction may get you real close, nitrous and traction would smoke me.

Damn, that G-tech is much nicer than the original unit. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
New goal is 11's right? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Texas Term - where are you doing the swap, plano? I work in Plano. If you are going to be doing it today, I'd like to take a look. Send me a PM if you are.

Texas Terminator,
i haven't changed anything that will help you. my timing charts are all the same, i have changed my injector flow rate and PE/rpm but those are both very spacific to my fuel system.
i did up my idle to 600, the 6.0 seems to like that better
