i really think something's wrong with 13's on nitrous....i did 13.6@ 105 w/futura street tires (19psi). that was my first time EVER at the track. i had a 2.14 60' and my car was BONE STOCK. then i did 13.5@106 with everything i have now (flowpac w/out lid and loudmouth)

 

What size shot were you running? I am gonna assume an auto since you got the 2.73 gears. Were you spraying off the line? Do you have anytimes w/o the spray? I will agree with you, Something is wrong with you spraying and only getting a 13.5.

 

75 shot, A4 with 3.23 gears.
N/A run
60' 2.146
1/4 13.878
mph 102.61

on N2O
60' 2.155
1/4 13.180
mph 109.71

 

Sounds like you need some more wheel time and a stall asap! still in the 2s (60) with a 75 shot isnt to good make sure the kit isnt surging or something along that line of the nos not activating correctly .

 

I had better 60 foots with my made-for-wet-traction tires and I was still in the low 13s N/A... 2.73s and stock stall.

 

how many miles are on the car?? also i would do a complete sea foaming on the car, so that maybe it will clean your fuel injectors which may possibly be clogged up with some bad gasoline you bought previously.. check the plugs and make sure there not black with oil. and make sure the plug wires are not sitting against the exaust manifold. with your speed it should be a better ET, and guys were trying to help him out not to hear bout what your car runs..

 

112K on the clock, I just seafomed the car about 1K miles ago. I've owned it for about 5 months now, and I have always put in chevron 91 octane. If the plugs are black wth oil, what does that mean?

 

I hope that you realize that your reaction time has NOTHING to do with what times you run.

It's all about the 60'

You definitely need to have a pressure gauge. Get yourself a bottle heater also so you can regulate your pressure. That's very important.

*update your sig, you are running different plugs gapped differently.*

 

updated SIG, but even the N/A runs are bad.

 

Im going to be trying out different tire PSI.

 

Oh yeah, like mentioned, remove your front sway bar. Will take a little weight off and help with weight transfer

 

if the plugs are black its time to change them LOL.

 

I mean what if there oily?

 

Most likely the PCV system is sucking oil into the intake and then down into the cylinder bore. Does the car smoke on initial start up?

 

Hi, you still need some sort of datalogging. See if you can find someone local that can help you out for a case of beer or something.

As far as your shock situation goes, every single suspension component contributes to how the car works. If something is FUBAR'd your ET will suffer.

As far as your plug situation is concerned, are you seeing oil on the porceline, or the thread? Oil on the porceline is blowby from the rings. Oil on the thread is not uncommon.

 

your mph should be higher than it is..... i ran 13.5 @ 109 on motor and street tires....

 

I had oil on the thread. The previous owner, was invovled in a acciendent with this car, it was hit on the driver's side. The front left arm was replaced, at first I was concerend about this effecting my et's, but I got it on a lift and the suspension looked ok.

My buddy talked to a local tuner, and will give us a deal using HP tuners. But im not sure I want to tune it before knowing everything else is ok.
What do you guys think should I have it tuned or should I get wideband dyno, or something else?

 

If you don't know what you are doing, then have a tuner look at it. Tuning isn't always just to make the car faster. They can see other possible problems with the car. Just be preparred to spend some big bucks.

My car hit a concrete barrier with the previous owner. Right rear.....car launches great
