yea Bob, I have been thinking about that. When I go through the traps, in
4th, I'm taching about 4500-4600 rpms. My optimum shift point is 5500 rpms.,
now, if I were to keep it in 3rd through the traps, I'd be turning around
6000 rpms, which is a bit to far out of the power band. All that may change
when I get my PCM back from Leach next week, it may change my HP curve???
We shall see. But yes, you're correct, maybe a 26-27" tire might get me
around 5 to 5500 rpm range at the end of the track, in 4th gear?? A 4.20
gear would be something else, 1st gear would last about 3 feet, maybe even
start out in 2nd, 4000rpms, and dump the clutch ;)
Yep, traction bars were my first modification, a MUST have for a 5spd, and
well worth the 29.00 bucks! I also have the spring clamps, I didn't notice
any difference with those, they're still on the truck.

~I know that there's a parallel thread on drag radials going on at the same

~here.
~When I went from 28" drag radials to 26" drag radials, I dropped about
2/10s
~off. Not only would they give you an effective gear ratio of about 4.20:1
~with
~your 3.92 but the 26"ers are a lot lighter than than the 28"ers (less
unsprung
~weight).
~I'm not sure if your mods included traction bars or not. If not, at my
last
~trip to the track, I took off 3/10s by putting on some homebrew spring
clamps
~on my third run. Now I also took off 55 lbs of weight at the same time on
~that
~and subsequent runs. Even if I generously allowed 1/10 for the reduced
~weight,
~that would mean that the other 2/10s was most likely from the clamps. I'll
~see for sure in the next few weeks as there are a couple of mopar drag
racing
~events being held in Ont.
