I am stumped
I am stumped Does this sound right?
I used to trap at 125mph w/ old 4L60E, 3500 stall, and 3.73s on 26" tall tire
I now have a 28" tall tire, 4.11s, Turbo 350, and 4500 stall.
I banged out my rev limiter last night heading through the traps. I think that I should have about 132mph before that should happen. Any comments?
btw: the car is reflashed to think she has an M6 and rev limiter adjusted up to 7000.
she ran great at first: 1.6 60' and did the 1/8th mile at 7.1 @ 99.49mph. The end result was the rev limiter at the end not being able to accelerate all the way through the traps

were you locking the converter with the 4l60 before?
when i was TH400, i had 4.10 gear, 28" tire..cleared the traps in the 1/4 with plenty of room. i think i had a 4000 or 4500 stall.

that is what I am suspicious about.
I have a Hughes 4500 stall converter and am not sure if it is locking up or not. I assume she does after 4500, but am not sure.
with the TH350, off of the line I am staged about 4000rpm and launch. I am already in 3rd gear. The rpms slam up to around 6500 and just stay there the whole way it appears.
When I ordered my stall through alamo performance, they did not ask lock-up or non lock up
any way to tell?

well its not just converter. with a 350/400 trans the trans itself has to be a lock up trans and i would have to be on a switch and manually locked up I would imagine.
remember a converter does not lock itself up..a selenoid in the trans does..
let me get this straight..you are launching the car in 3rd gear?

yes. I launch in 3rd at the time (still with stock shifter and really really hard to gauge whcih gear is which). Do not want to accidentally slap it up into neutral at WOT.
my trap was 122 (after coasting a short while after banging the rev limiter)
