what else do i need to get my 3.4 into the 15s??

[1fstSS]

i ran 16.8 N/A and im goin to the strip saturday and plan on spraying my 55 shot, will this alone put me into the 15s, or will i need some more stuff?? oh i also have a flowmaster exhaust, not the whole cat back but the muffler.

a 85 shot drop .6 of my 1/8th mile time, but i have a 3.8. try the 55 shot jet then a 70-75 shot jet if you still cant break the barrier. try unbolting your exhuast or run w/o a filter if the jet change couldnt get you past 15's. good luck

all the free mods help. took me from 16.8 to 16.1 but that was at sea level with extremely good weather and excelent track prep. I hit it with only a flowmaster and a CAI. What brand tires and tire size do you have? I am runnign 245/50/16 BFG G-Force T/A KDWS's all around. Helps a lot. WHat was your 60ft last time you ran? to break into 15's you need something like a 2.2 flat at least.

2.2 to get into 15s??

60ft -2.328
1/8 - 10.098@70.63
1/4 - 15.647@87.42

what I ran with my 99 3800. 3.08 open rear, A4. Only mods were K&N filter, FRA and Whisper lid.

I'm getting new times saturday morning with my edge 2800 stall converter...probably wont be much better due to me not installing my 3.42 gears and posi. :(

you really need to open up your exhaust more. 3.4L love to have there exhaust opened up more... so either unhook the catback or get a bigger i-pipe.

I ment a 2.2 60 for the 3.4L N/A. If you ever go aginst a 3.8 the 1/8 will be close but then they will fly by you in the 1/4. remember they have a 40hp jump on you and it shines above 50MPH at the track. on my 16.1 I pulled a 2.25 60. thats why I say you need atleast a 2.2 on a 3.4. Then again with nitrous you use it at high rpm(3000+) right? Maybe you don't need a 2.2 60.
