what am i doing wrong?

[stevethepirate]

i went to atco last winter, it was 32* out, i had my subs in the back, my tires were pretty much bald, etc.
i ran a 15.281 @ 88.5 with a 2.19 60'

i went back to the track 2 weeks ago, after having done a whisper lid, k&n air filter, and a TSP catback. i also removed my subs, and got new rear tires.
i ran a best of 15.279 @ 88.5 with a 2.14 60'.

judging from these times, what should i try to concentrate on now? i have 3.42's, should i go lower (3.73)?
should i get a posi to try to improve my 60'?
suspension?
just go for power? (nitrous, headers, cam, etc.)

Re: what am i doing wrong?

LSD and sticky tries would help alot....

also becuase of your mod it sound like you may need a tune to get teh most out of them

Re: what am i doing wrong?

would the sticky tires make a big difference even though im not really making enough power to not be able to get traction?

what rpm are you lanching at? and do you have a A4 or M5?

Re: what am i doing wrong?

The difference in DA between 32° and 60° is 2,000 feet.

NHRA uses .9853 for a 1900' elevation ET correction factor.

That means your 15.279 would have been a 15.054 at the same temp as your first run.

To calculate your DA you need temp, barometric pressure, dew point and this calculator.

Re: what am i doing wrong?

LSD and sticky tires.....nitrous wouldnt hurt :D

Re: what am i doing wrong?

its an A4. im not sure exactly where i was launching, im sure it could have been higher though.

Funkz- thanks for all of that, i still wish my time had been better though :p

and trust me, nitrous is coming ASAP. im just trying to find a used kit for somewhere around $450. not many good ones popping up.

Look at it this way. If it hadn't been so cold the first time your ran your car, it would have done 15.4 - 15.5

You've dropped 2 tenths with your intake and cat-back. If you really want to see that 15.0 then just wait until it gets real cold again and go back to the track. :)

Re: what am i doing wrong?

it was still pretty damn cold when i ran it this last time. it wasnt 30*, but it was probably 45 or 50.

anyone have a nitrous kit for sale? :p

Here's a new one for $469

And another new dry system for $350

Re: what am i doing wrong?

yeah, i was just looking for a used one because its cheaper, and would come with some of the extra safety parts

[WishIHad$$$]

Re: what am i doing wrong?

Just be wary if you go with a used kit you are buying used parts. If one solenoid gets stuck open there will be dire consequences.

Re: what am i doing wrong?

Don't jump on a nitrous kit right away.

You really haven't given us much info to work with.

Give us all mods, complete run (60, 330, 1/8, 1/4 etc).

Launch rpm, track temp, condition etc.

Then we procede from there

With a 2.1 60 foot your still not getting traction.. With sticky tires and LSD you could launch at a much higher rpm, meaning more in your power band and knock some 10th's off your 60'.. every 10th off the 60' is usually 2 tenth's off your et..
