What does it take to put a GTP in the 13's/12's?

What size pulley and how extensive would you have to mod the car I know the pully drops and everything I would assume a 2.8 on slicks or so someone let me know.
 


13.99999:

3.4(ish) pulley setup and the driver mod

12.99999:

a full size intercooler w/ whatever pulley you can run, rockers, headers, and a driver mod


however, this isnt typical at all. usually to run 12s people need a cam setup or more because they either cant drive or arent willing to buy sticky tires (slicks). there are also about 1000 different combinations you can do in order to make power. e85 is a great trick for good power on the cheap.
 


with slicks and a pulley drop Ill be in the mid 13's id hope Still have cam sensor issues and need to get dyno'd though
 
you have an s1x and a built tranny with 3.29s. how can you not pull a 12 second pass? try harder, im telling you that your car can run that.
 
I am more interested about 12's like what supporting mods minimal and what whp. Just curious if people ever did this on a stock trans. Thanks for the replies
 
you would need:
Headers
Rockers
E-85
Meth maybe
Tune
Small pulley
Sticky tires

Trans would hold for a while slicks would kill it quick tho.
 


honestly from what ive noticed people usually break into the 12s when they reach the 300 whp area. some people who are better can do it on 280, others need 330. being able to launch our cars really is the art of it all.

how you want to go about that has a ton of variables.

Honestly since the build I havent played with it all that much its got around 700 miles on it But i still have a cam code Probably a broken wire in the harness Just havent pulled it out to ohm out yet
I also want to dyno tune it and drop to a 3.2
Also need headers and im torn due to the smog SH1t cause im in ca
I know the car moves just havent really pushed it
 
I just wanted a daily driven 12's sec gtp obviously with reliablilty. I have a dhp ecu, gonna do fenderwell intake, headers and dp, a vs cam, e85, and maybe if I can find a cheap intercooler. Hopefully that will put me there
 


Really just cam setup and tune, or rocker intercooler setup and tune. The tune is the biggest part, if they know what they are doing in the tune and you know what you are doing mechanically. Especially if you want to keep it a daily driver.
 
FYI, I went 13.4 @ 102 back in early 08 with pump gas, street tires, full int. w/ tire & jack, 3.4", XP, Headers, Base DHP tune with raised shift points and the P0300 code turned off, stock TB, Ported S/C, Stock trans, 3" FWI, MSD Wires/Coils/AL103's, 160*, with a 2.05 60'. Probably could have hit 12's with a ported TB, custom tune, higher octane and a 3.2"...never have gone back since though...what made me mad is I didn't run much faster...I had the same mods but instead of the cam/headers...I had 1.84 Rollers and PEM's and a 3" DP...went 13.85 @ 99...with a 1.89 60'...driver mod makes a lot of it.

You have all of that stuff and are on a 3.4 still? I only have headers, 180* tstat, AL104's, Poly Mounts, Full Custom Catback, Ported SC, Ported TB, and Custom Tune. I run a 3.25 pulley with minimal 1.4* kr but I'm pretty sure a new tune will kill the KR.

Fastest i ran before the Headers, Ported TB, and Ported SC was 14.1 @ 98mph.

Come Spring i'm taking all of the dead weight out of the trunk for a few passes. I just gotta label all of my stereo wires so i know where to put them back at. :th_laugh-lol2:
