OK.. I took my 98 T/A down the 1/4 six times today just to see what she would run. I have to say im a little disapointed. My worse pass was 14.1509 @ 100.44mph. With a .1521 reaction and a 2.2798 60ft. My best time was 14.0098 @ 101.35mph. With a shitty .7281 reaction and a 2.2720 60ft.

Now it was hot. Really hot today. 95-100 temp, with track temp around 135-140. The car did spin a little off the line but not to bad. I just really thought she would run mid to maybe upper 13s with it being that hot??

Ok heres the low down on my ride. Its a 98 base model Trans Am with a little less than 54K on the clock, a stock A4 trans and a stock rearend. I had about 3/8s tank of fuel in it and I cleaned her out so there wasnt any extra weight in it. Now my mods are SLP air intake system, march underdrive pulleys, hedman long tubes with 3in offroad Y. Flowmaster system from the Y back. I have taylor wires and Ngk plugs. SLP fan controls, the cars temp was around 180 or so during the runs. Now i do have eibach prokit on the car and i know that will hurt my times abit. I have 18in ZO6s on the car with a good set of 285/35 nitto nt555s on the rear. I was running 30psi in the rears.

So what can i do?? Now ive read on here that my cars got shitty knock sensors from the factory and they pull too much timing out?? If someone could explain this a bit more id love that. How much gain will i get from upgrading to the newer style sensors??? I think im going to do an intake swap here in a month or two and will probly swap the sensors then. Another question i have is what size dragradial can i fit on my stock 16in wheels. I was thinking like a 26/10.5. Will these hook better than my 285 street nittos??

Ok so my future plans are RPM Speed 3-Point Subframe Connectors (should be in next week). LS1 Power+Plus Typhoon Manifold. I would also love any info on this intake. Are there differences or other things involved when doing an intake swap on a 98?? And then last on the list is maybe a little 100 shot nitrous kit over next winter.

I know i have alot of questions but i really need ur guys's help. Thanks for all ur input!!

PS: I know i could do a big stall and lower gears but i think im going to leave that stuff stock 4 now. Thanks!!!

 

that heat sure didn't help but neither did your 60ft times! what type of gas were you running? you need a stall and tranny first in any A4 car! but DR's are right after that they go hand in hand so-to-speak! and if I were you look for a LS6 intake with P&P TB or even better a fast 90/90 intake or maybe a Fast 78 intake if your not serious about the future drag racing ET's?but if you do the intake you might as well do a cam swap also! try the MTI-X1 along with whichever intake you choose and of course the stall first! good luck either way!

 

reaction time has nothing to do with your times it so don't worry about that right now unless you are bracket racing the car. its that 60' time and the heat and humidity that is killing you possibly more..

Lowering springs, heavy wheels and street tires slow you down too killing the 60'. pick up some MT ET street Drag radials 255/50 16's and toss those on the stock 16' wheels. Also have you gotten a tune after the headers? some cars end up running really rich after headers.
