Can I Break Into The Mid-high 13's?

[nsta]

Hey guys im about to go to a drag strip and was wondering what sort of time i should be getting around roughly.

Healthy running Auto rb25det motor, ecr33 series 1 coupe, with 255rears and 235 fronts

Mods:

Apexi pod cai

3" exhaust with split dump

hybrid fmic

turbotech boost tap @ 9-10 psi

im thinking the wheels will slow me down as theyre so big, but would help traction as well, what do ppl launch their autos at?and how (hold the brake down and rev????)

im hoping to crack a 13 (high) pass???any chance, hasnt been tuned yet, would increasing the boost for the run help of not??

at a guess you would be producing around 240rwhp with a PFC and tune at 12psi you could reach 300hp and that would get you low 13s with a manual dont know with autos.

[nsta]

so a tune is the way to go, how about without the tune, and 12psi?would that be a tad bit dangerous, rich condition etc....?

And how about the tyres, are 265 rear too big for drag applications?

[FATAZZ]

the bigger the better i say

16"s with 225 on my auto 2L spun half the track

from a 3500-4000rpm launch, 1 foot on the brake & other on the gas

15.1 stock except exhaust and pod

i now have 18" 265's so ill be heading out to WSID soon to see if it spins again.

p.s the bigger the wheel the more terminal velocity you will have when picking up speed down the track. i.e slower off the mark,but more top end speed.

[nitemare5]

he said he had an auto box so he won't have a pfc

i would probably look at getting some form of piggy back ecu and getting it installed/tuned, then taking it down the strip. or even just get a dyno run with the increased boost just to make sure the AFR are ok before blasting it down the track all night.

i think a mid 14 is more likely.

[lukits01]

Unless your tyre and suspension setup is perfect, I'd doubt if you'd be able to get 13s on an Auto R33. Not enough power, stock ECU can only do so much.

Mid to low 14s is doable

[nsta]

why is the auto slower than the manual counterpart????, i feel my bottom end is really good, its the top end which feels very flat to me????, why is this??i would've thought it the other way around?is this a factory turbo thing, or cause it hasn't been tuned.

Btw im thinking of getting an safcII and have it tuned, instead of going manual/power fc just jet.

p.s my dump pipe will be installed coming monday, will this prove gains in my top end, my 1st and 2nd gear feel good, after 3 it's losing power im sure of it heheh

Just thinking of what to do now....

SECUR1TY has what you have and along with an SAFC (about 195rwkw) managed to do a 14 flat.

at a guess you would be producing around 240rwhp with a PFC and tune at 12psi you could reach 300hp and that would get you low 13s with a manual dont know with autos.

lol you wish. 300hp on stock turbo at 12psi is never going to happen.

[Kaido_RR]

just to let everyone know i ran 14.3 with 185rwhp.. with no top end (rb25det with rb20 turbo it would drop off boost after 5000rpm) -(car(r33) had exhuast (catback and front pipe no dump) airfilter, clutch)

so i think 13's is very doable with ur current setup

lol you wish. 300hp on stock turbo at 12psi is never going to happen.

not sure of the psi lvl but i know of a few rb25det running stock turbos getting close to if not hitting 300rwhp

[nsta]

thanks for that, im hoping to achive a daily driven 12 second gtst, with a bigger turbo is this very much doable???

Why would you run a rb20 Turbo on a rb25?????

[Kaido_RR]

Why would you run a rb20 Turbo on a rb25?????

dont ask me bought the car like that -long story

[mr_crust]

ive got an rb25 (auto) with:

FMIC

Pod + heat sheild

hi flo cat

3" exhaust cat back

and on stock tyres, 6psi boost and no real launch i ran a 14.7, with decent launch i got 14.5...

i got my boost controller this 2days back and im getting proper tyres

front 235/40 and rear 265/40

now with 10psi n decent tyres i will run a 14 flat with no dramas im guessing, but we will c in a few weeks, so its not impossible

[nsta]

hey thanks heaps ppl, i've decided to get a safcII and have it tuned, what would you say i'd be (~200rwkw)???, and what boost should i tune at, safely - 10psi ok?

[cerci]

will tell u 2mrro night buddy

i have 208.8rwkw

i want low 13s

[nsta]

please tell me how it goes:)what mods?

[race_snooze]

well rough idea for you i am geting 13.4's with 265 35 18" rims, gtst 33 200+rwkw constant wheel spin in first, WSID is a slippery track. Next run i am getting some 16" rims with 225 65 slicks, should break into the 12's. Also i have no camber kit, which is giving me lots of neg camber (not much tread in a straight line but lots a round corners)
