7AT Times and Launch Tips
 

After doing some research I have figured out that the best times seem to come with VDC off. I have also read that removing the brake fuse is also beneficial. If anyone can confirm these 2 tips, with experience, please do so.

While you're at it, post your slips and mods with any additional tips for launching the 7AT. If you ran completely stock, those times would be appreciated too.

never ran stock but at first with just my exhaust i was running 13.1-13.5 depending on conditions and whatnot.

added intakes and tune then ran 12.89@111mph as my personal best the next day.

There's a thread for time slips.

Pulling the brake fuse is so you can stand on the brake and launch at a higher RPM (avoids throttle cut when both are fully depressed).

Not sure what consensus is on best launch method, but I'm sure someone else will be able to weigh in on this.

any time i have apply any throttle for a launch with the 7AT at the track it ends up in wheel spin and higher ET times.

That figures. I didn't think anyone could even get off the line revving much above 2.5K anyway, which is around when the throttle cut kicks in.

Horsing around with brake stand launches has always gotten me rotating :p

yup!
thats why i just light brake to hold me on the line.
3rd yellow light hits
smash gas pedal to the floor
about 7200-7500 RPMs - grab 2nd lol
and you know the rest.

typically i'm at the redline in 4th at the finish line.

That thread has so many pointless posts, I honestly got tired of sifting through the BS. And they don't post their method of launching, which in my experience, is the most important part of a good ET.

launching the 7AT is a rough thing to do without good rubber out back.

launching on street tires has just resulted in wheel spin for me.

i havent had drag radials on yet so maybe with those and good track prep i can launch and come back with my experiences.

that wont be until next spring though.

My 7at .. Launching advice
 

i got a 2013 touring sports 7at with stillen gen 3

best advice on how to launch the car from the line and what gear to put it in from a 20 roll out, i usualy put it in 1st gear.

advice will help, got a big race tn

someone just started the same thread a hour ago.

i win!

lol nice work Presto :tiphat:

:rofl2:

thanks guys

Merged

where is said race taking place? if it's not on a prepped drag strip that changes everything since a strip is set up for traction launches.

i wanna merge with you :yum:

on 20 roll out, what gear do u put it in

well you're gonna be in first. no reason to jump to 2nd and risk getting stuck in low revs.

i'd say first with some good throttle control.

what tires do you have and how new are they.

my RE-11's when new allowed me to dive right into full throttle and was pure traction. it was sexy.

:bowrofl:

The RE-11's are good tires :tup:

yea and especially when i went up to 305s in the back lol

skip breakfast lunch and dinner and a good laxative should send you where
you want to go................good luck amigo

:bowrofl::roflpuke2::bowrofl::roflpuke2::bowrofl:

mmm.... I have a stack of sport rims with 265/305 RE-11s waiting for me to cord my current tires :driving:

i got the same set-up. 265/305 RE-11's on sport rays. they are amazing.

got about 10k miles on mine and seems to be holding upbetter than my PSS's

I am looking forward to it. I picked em up for $1K with only a few track days on them :tup:

I'm particularly interested in the tip to pull brake fuse. Have people done both while at the track and seen better results?

If you can't put traction down on a high rpm launch, pulling the brake fuse isn't going to do you any good.

i got mine $1200 new with shipped lol :stirthepot:

i dont see a reason. i have never pulled mine and i still can sit there and smoke my tires in the burnout pits at the redline all day.

although i rarely do it based on burnouts on street tires is basically pointless.

quick spin here and there to clean debris is about all you need.

:iagree:

with Ray's wheels? As in, I have a second set of sports Ray's now ;)

mine a 2013 touring sport, so what ever tires come with the sport package, potenza i think or something like that. the tires have 12k miles on them and the threat is still soooo good .

20 roll out i slap it into 1st gear and I'm at aboutt 4k rpms and i gas it from there

off the line, i full gass it but my tires are spinning, i think i have to gas it half way let go and when i catch tracting then stomp on it.

im racing a 04 350z supercharge, i beat him already off the line but last night i was spinning like crazy, and i beat him second race.

20 roll out i know i got the Z.

Are you running 305/30 on the back?

Springs or coilover or stock?

My best bone stock run on street tires (Michelin A/S3 285/30/20) was 13.3.

A few weeks ago I went to the track with drag radials and it dropped 1/10 second. I think our cars are too weak stock to utilize the radials at its potential.

I brake torque to around 2k on street tires (didn't pull fuse) and 2.5k on radials (pulled fuse)

For me still on the stock tires track prep is what makes the most difference in my times. On the worst windy fall day with trees next to the staging lanes dropping leaves all over I got a 14.8@107 spinning the tires through 1st and 2nd gears. On a nice summer day on a big bracket racing weekend where 90% of the cars were on slicks and I only got a few runs in between rounds. I got 13.0@109 just because the track was so sticky that my tires didn't spin.

yes.

RE-11's

265/35/19 Front
305/30/19 Rear

on OEM sport pacakges Rays

no suspension mods. all stock.

Here is my best run on stock sport rays and Michelin pss's in stock sizes. Also no rpms at launch just gas smash at the light.

Geez, what car was in the left lane?

evo runnig slicks and around 25-30psi of boost lol

well arent you just special lol

i will eventually grab a back up set for mine......but for drag radials :stirthepot:
