hey everyone i have heard from several when dragging at a 1/4 track you only wanna go through 4th gear, in my only appearance, i found right before the end of te 1/4 everytime if i didnt shift into 5th i would redline, what may have caused this? was i shifting prematurely in the previous gears, or is it just the stock 323's in my rear? also is 18 psi a good seat for the rears? and do i wanna launch the car from 0-or like 3k rpms? how long does everyone let there cars sit in between passes?

go through the traps in 4th. youll be fine.

and you should have 3.42s in the car not 3.23s. also why did you change your pushrods???

well i tried downshifting at to high of speed and tottally bent 2 pushrods so i went with some chrome moly, how about launching.. what do you think? so i do have 342's? i have abs and traction control if that matters

How the hell are you hitting the rev limiter in 4th gear at only 110 MPH??? Do you have some of those "low-rider" mini tires on there?

Demonicbird00

iTrader: (17)

yeah you have 3.42s

what tire are you running? rime and tire size

all i know is my car was untuned when i took it there and the next day i ad it tuned and te guy said i had alot of detonation, and the timing was all off by like 9 degrees? all i know is she runs better than she ever did after the tune, and was wondering if the detonation and timing being off would have effected the way the car was performing as far as shifting goes

no, tuning has nothing to do with gearing, maybe you have 4.10's and you dont know it? 3.42's take 4th gear way past the 1/4, or is it 4th that you want to shift into at the end of the 1/4? As far as launching goes, every car is a little different and only track time will give you that answer.

i think i figured it out, i remember when launching i was spinning the tires alot, im tinking since i was spinning it was revving really igh causing me to shift into second waay to early, when leaving the tree on green, should i be easing out then nailing it of the block or moving like a bat out of hell?

spinning off the line=higher trap speed, higher e.t
hooking=lower trap, lower e.t

As far as hooking goes, there is a fine point that your car will launch great from but you have to find it. You will find your rev point...say 3k and then a quick slide out of the clutch. You should hear a chirp and grab.....well mine chirps anyways but its a quick drop of the clutch and the car doesnt bog but it doesnt spin. Took me many launches t find it. Find a local 1/8th that isnt too crowded and work on your 60's.

someone has put different gears in it. if you are shifting to early like you say you aree, that would lower the RPM's sooner and put you lower at the stripe. in my car, i cross the line at 4800 RPM in 4th at about 109MPH.

ok if you have 3.42s then 4th gear will take you to 144 mph at 6.2k.

if you have 4.10s then 4th will take you to 120 at 6.2k.

if you have 4.56s then 4th will take you to 108 at 6.2k

thast based off of your tire size (245/55/16) which would be 26.61"

and in order to find out what gears you have, you have to count how many times your tire rotates in 1 revolution of the DS.

hope that helps.

honestly...youre just driving bad...

my buddy was complaining about his ET when we went to the track one day..saying he missed 5th right before the traps...

bottom line...if youre going into 5th, your short shifting something horrible. Just like demonic posted above...even with 4:11's in the rear, you wont be going into 5th.

You just need to practice and get your driving down.

lol i really dont even see how it's possible to come close to fifth gear with stock gears and only trapping 110! LOL

245/55/16 no syuch tire its a 245/50/16 is stock size and there 24.50" I know thats what is on mine ....did you buy the car used???you said the tuner said the timing was too high....sounds like hypertech had ahold of it one time or another.....and im bettin there is 4.30s in that car maybe 456s....hell take it out get up to 60 in 4th come back and tell us what rpm you are at.......

12s on street tires is pretty good though

4.30s or 4.56s in a stock 10 bolt? uhm, no

I know this car and it definitely does not have anything higher than 3.42's in the rear. It was a bone stock formula when my buddies gf bought it and then ricky bought it off her. I have no idea why you would be running out of gear as it doesnt seem possible. Im pretty sure the tires are right around a 26" as well.

oh i will agree 100% it was bad driving, it was my first time there, what i wanna know is when at the strip what is a good rpm to shift at...? or better yet what is redline?

5_02ls1

iTrader: (20)

well there not the stock 16s...........if it has the 16s they are a 345/50/16 and 24.5" tall....

maybe the clutch was slippin i dont see how bad driving would cause it to be at the redline through the traps.....

are you sayin it cant be done????there isnt but about 500 cars on this website alone with those gears in m6 cars..........
