 Subject: Track times from 2000 R/T within:
IP: Logged
Message:
Ok, made it out to the track last night with some pretty decent results in my 2000 R/T. One thing i was somewhat disappointed in was my Mopar PCM. I could never get it to shift at 5200 unless i did it manually. One time it shifted at 5200 in first, but 4400 in second, so i had to resort to manually shifting to get the best times.
My mods to date: Mopar PCM, K&N GenII, cap/rotor, 8mm wires, 180* thermostat, IAT adjuster.
Heat was a killer last night, as the first time i ran it was 93*, but ended up cooling down to the lower 80's by the end of the night.
***This was a 1000'(with 1/8 miles also) track, not 1/4 mile***
--------
Run #1 - (First time to ever take truck down the track)
.813
2.392
6.685
10.207
70.38 mph
13.025
80.11 mph
As you can see here i was VERY traction limited. I couldn't hear if i was spinning b/c i was racing a 10-sec camaro.
--------
Run #2
.800
2.328
6.572
10.068
70.83 mph
12.865
81.00 mph
Only change i made here was uncapping my exhaust. I also shifted a tad bit earlier (manually @ 5100) - I NEED A SHIFT KIT BAD!!!!
--------
Run #3
.541
2.257
6.377
9.868
70.98 mph
12.663
80.81 mph
Mopar PCM learning more? No changes made here except a better burnout and launch. I stalled it to about 1200, which seemed to work in my favor. Still a bad 60' time though.
--------
Run #4
.699
2.186
6.279
9.700
72.27 mph
12.455
82.04 mph
I capped my exhaust cut-out this time. The truck was also cooler and i did a much better burnout - and the time reflects. I think the biggest difference though was the PCM. I left it in '2' and it shifted out of first at 5300, and i manually shifted it from '2-D' at 5100. I think that must be the biggest improvement. I NEED A SHIFT KIT!!!!!
--------
Run #5
.624
2.235
6.359
9.797
72.00 mph
12.558
81.93 mph
I hot lapped it on this one and couldn't hook up. At this point the track was starting to get a little slippery.
--------
Run #6
.800
2.328
6.572
10.068
70.83 mph
12.865
81.00 mph
--------
Run #7
.781
2.244
6.362
9/875
70.64 mph
12.683
80.54 mph
Last run of the night. I left it in 'D' and hoped that by now the PCM knew my shift points - It didn't. It shifted out of first at 4800 and out of second at 4200. Anyone know whats up with this thing?!?!
I had a great time at the track. Main reason i went last night was to watch my dad in his '98 Formula with a few mods. He was running 10.4x's N/A and 9.7x's on the bottle. It was fun to watch his car woop-up on all the all-out race cars.
Now, can anyone give me advice as to what mods would help out the most next?? I know i need a tb, i'm just contemplating on whether to get the Fastman or Flowmetrics. What else after the TB? Also, anyone have any input as to why my PCM was shifting so early? I think it would really help if i could just leave it in 'D' and let the tranny do all the work, but unfortunately when it shifts at 4500-4800 in every gear, my time slows down.
Thanks for any help!

Your reation time SUCKS,when you see the light turn yellow stomp the gas it will be green by the time you break the beams and I would just stay with shifting it manually other than that just start adding mods.

you said you were running the 1/8 mile with 12 sec passes? if so i think you need to go back to the dealer. i have a 2000 dak club cab with the 4.7 and auto tranny, running almost a 10 flat, no mods done at the time. there is a r/t runs down at the track i go to running 9.7 sec passes.

The 12 sec passes are at the 1000' mark. Time before that is 1/8th mile.

yeah, i know my reaction sucked. It was based on a .500 tree, so the one .541 was pretty good, all the other ones were horrible. Guess i just fell asleep everytime =).
I think the times are decent considering it was about 85-90* during most my runs. My 12.45 (run #4) i think i could get down to around 12.2 with better weather/driving.

i havent ever heard of the 1000 ft thats blowing my mind. we just have a little 1/8 here and have a pretty good turnout on thursdays and saturdays. i want to run mine again since i have added a lot of weight to it adding six twelve inch rockford fosgate subs in the extended cab part. i dont know how much it slowed me down but im interested.
