dont think it matters when its a stock n. american celica =[

If you have some good tires, and a good clutch--i usually take off at 2750rpm.

I cant remember what I took off at last time I went but I was running like 16.6ish but I was burning through first and screetched 2nd which im pretty sure slowed me down.

If you were ripping all through first, you must've taken off at like 3k rpm man. What I do to reduce that wheelspin is when i take off at ~2700rpm, after a good 0.5 second of the wheels spinning, *this is gonna be hard to explain* i step off the pedal and stomp back onto it (doing this consecutively really quick) until i can start to see the car moving much faster than 2cm then i step on the pedal about 80% until it catches traction and then BOOM 100% and then i should be about 6000rpm right about now and then i shift and i rip my 2nd gear for a good 0.25s....
You need a better clutch upgrade bro, and I strongly advise after you get your clutch upgrade to make sure your motor is in good shape to be pumped like this because many people can blow their motor because their clutch can handle the high RPM's but the motor is old don't forget.
Anyway, i'm able to spin my wheels on 3rd and just a little tiny bit in 4th gear. (Don't forget I've a short-shift kit too.)
I've beaten a sentra se-r, and an h22a swapped accord that was tuned with a NEO and other mods, and a couple of integra's. It's all on how you do it.
Do a clutch upgrade and short-shift. Great mods, and while your tranny is out, ask to see if you can get your flywheel sanded down a couple of pounds.

you really have to see what works best for where you are and your car....
you should NOT be just dumping the clutch off the line as well...if you are you'll get into bogging/wheel hop &/or spin. you are going to want to slip the clutch just a weee bit.
and I at anyone who says they can spin 4th gear let alone 3rd (unless you are itchy) SSK doesn't help you make any power either....

[mrgt4]

depends on everything, tyres, power, torque, track...

i used to drop my clutch from 5k in my gt4 when i used to drag, would go like a bat out of hell off the line but then my clutch went eventually. lol

only done it twice since new clutch and grabs much more, can get the tyres to smoke. lol

[Akira_g4]

well the last two times i dragged, i took off at about 2900RPM. That seemed to work fine for me, ran a 16.9 best i can do

yesturday i was playing with the two step and launching
have twostep set at 4.5k right over where the turbo starts to spool up good, i make like 9 psi standing still and the only way to get out of the hole with out completey roasting tire is to killllll the clutch, but man it works pretty good...
until the turbo spools to full boost then the tires just break free anyway. wtf, then secound gear. traction for a couple split secounds and once it revs higher it just breaks free till 60mph where im just bouncing off rev limiter till my cars speed matches my speedo speed then i can shift to 3rd lol.

need wider tires. or awd. or both. wont be turning the boost up till either of those happen. i dont want my 3rd gear acting like my 2nd gear.

[playr158]

itchy have you tried launching in 2nd? or starting in 2nd?

[x_itchy_b_x]

no, not yet. once the turbo spools and i hit like 5k the tires just spin. so if i started in 2nd i bet id have traction for few seconds longer down low but once i hit 5k its pointless. i either have to rev it out and get the car up to speed to get into 3rd or have a crappy shift into 3rd and have the turbo spool up again.
its almost as good as vtec.

[mrgt4]

with 330whp im not suprised it lights the tyres up! lol

is it a 4wd conversion or the fwd still? bet its mental!

[x_itchy_b_x]

i wish it was awd, fwd for now. thanks

[mrgt4]

id quite like to drive a fwd with all that power, closest i have done is a type-r civic and on forza2! lol, my fensport celica copy, how crap that you cant make them 4wd.

nobody over here i know realy has mad hatter fwd, most is actually my mates with 225 at the moment. certainly wouldnt mind riding shotgun in a car like yours though!

Killer problem to have.
Your car has always [and still is] an inspiration for mine.
You still breaking things?

Haha thanks man. i put alot into the car thats for sure.
I haven't broken things recently but i have a feeling my 3rd gear syncro is gunna break soon. its been grinding latly I'm not familiar with transmissions really, so i guess its going to force me to be when it breaks.
i'm hoping it lasts the summer.

[_mikeE]

Ever consider e153 tranny? Having the benefit of LSD. I think my 1,2, & 3rd gear synchros have gone bad on me now, need to change soon might consider rebuilding tranny..

[x_itchy_b_x]

the next tranny... Transmission in my car will be the awd one i have out back. hopefully. or another s54 until the awd one. Id love to have an e153 but it would just be wasted money i could put towards awd at this point.

[DEATH]

the next tranny... Transmission in my car...

I got that one

[presure2]

john, you need the E153.
you know me, i was never FOR that swap.
after driving supershannons swap, with the e153, i REALLLLLY liked the gearing SO much more than the s54. (for the 3s swap anyway)
although then again...i know what you have in mind, so, i guess you dont NEED the e153..but you can get the non lsd version for ~300 or so in bone yards.
