i am currently seeking to getinto the 12 in the spring when the track opens up. i need to know what elese i need to hit a 12.9x. any comments, suggestions, help will be greatly appreciated. here is my current list of performance stuffs. i am hoping i will only need sti injectors, supra tt fuel pump, and a used unichip. as soon as i hit 12s im quiting on speed and working on BRAKES and suspension.

hks hiper catback
hks downpipe
godspeed uppipe
greddy trust intake
ihi vf30
16.2 psi

im in the exact same boat as you, except i didnt install my VF30 yet.

doyou already have it? install ws pretty straight forward. you're gonna love it youll have power to redline intead of power drop off at 5500!

HAHAHA classic, there is someone who has been around the block before.

for a super high 12, I wouldn't think anything........

if you want to buy parts, injectors, pump, and engine management.

i think you should be able to break the 12's like that. Or at least be very close. But I thought the stock injector would max out at like 15 psi with that turbo? That's the same set up i have basicly and i hope to break the 12's like that. But i also plan on adding injectors, fuel pump, ecu, colder plugs and maybie a larger intercooler. Then run 18 psi and then i know I'll be well into the 12's.

You definately need fuel system upgrades. My injector duty cycles are hitting 100% with the following mods (keep in mind I am on the stock turbo)...

TurboXS up-pipe
ScoobySport down-pipe
ScoobySport catless center section
Borla catback
UTEC stage 2 map at 15.5 PSI

With a VF30 at 16.2 PSI your injectors have to be holding you back.

Theirs no way your hitting 100% duty is their? On the stock turbo with such low boost?

I didn't feel like booting up my laptop to get some of my recent datalogs. Here is an older datalog. This log is prior to the up-pipe install. I'm on the stock map and only barely hit 15 PSI. IDCs touch 100% a couple times. Ambient temps were about 30 degrees. I bolded the 100% IDCs, but notice that my IDCs are above 90% from 5000 RPM up.

you should be able to hit a 12.9 with that if you're a good driver, but your car is going to have to be cool and the air needs cool as well.
