Car is a 1994 a4 trans am lt1 with the only mod so fart being a flow master exhause. What's your recipe to get me into 13.1-13.5?Thanks for the help.

 

You're probably not far off, try:

-drag radials
-throttle body coolant bypass
-160* thermostat
-cold air induction kit

If you're still on the edge, you could do a stall converter as well and/or a gear swap (if you've got 2.73s).

 

Ha, I thought you meant compression when i read the title.

Anyways, id go with cai, gears, and tires next.

 

Full exhaust, CAI, and DRs should be all it takes. Hopefully you'll be luckier than me. I should be running that time easily but I hit a 13.8 wall and lost 3 mph by adding LTs yet running the same 13.8 add a few hundredths and I have to figure out why my car is down on power.

 

Its not hard, Jon94Z went 13.58 with just a Borla and Cold Air, he was on regular tires, no Nittos. The car went 2.0 in the sixty, stock converter and stock 3.23 Gears. He took out the back seats and had like a 1.4 tank of gas when he did it. But I was looking at his time slips, weather and track prep play a huge part. Get a converter since your getting tires

 

I had a gear, CIA and 52mm throttle body when I did it.

 

see times and sig below, at full weight with spare and everything

 

Just the Longtubes, cutout, and CAI got me the times in my sig. I havent been back since. Full exhuast and CAI will get you there or you can do gears, drag radials, and CAI should get you low to mid 13's fairly easy. Do both and you could pop some high 12's if you can cut a sub 2 sec 60ft time. Unlike me But some BF DR's will soon be here to fix that problem and prepare me for this fall

 

Was the weather conditions the same when you ran with the Longtubes oppsosed to before you had them and ran the 1/4?

 

The conditions were not the same. I ran in April and got my 13.80. In May on a fairly cool day I trapped 103.7. Last week when I ran it was quite cool out and humidity might have been up a tad but the air didnt seem that heavy. There was an oil spill in the lane I was forced to run in during the bracket races. Even with those conditions I wouldnt think that would account for a huge loss in mph, or would it? My LT4 KM will be in tomorrow and I'll see if that helps now but I'll need it sooner or later anyway.

 

gears, catback n the intake should get ya the 13.5....lontubes will get ya close to the 13.1
