OK, What to do next? C5 Performance I have a 98 C5 with CNC 5.3 heads with 2.02 valves, 224/228 113LSA cam headers, corsa, ported TB, ls6 intake, Veraram, underdrive pully, 3200 stall, and 373 gears. Without breaking the bank what do I do next to increase power? I am not a NOS guy. It layed down a low to mid 12 with a poor 2.1 60 on a COLD night. I do SO want that time in the 11's.

Better tires and more practice launching your car at the track should get you 11's. What did you trap bro ??
I was on Nittos DR's set at 21psi short heat up, and couldn't hook for ****. 2.11 60 and 12.02 1/4 at 123.6 mph into a headwind.

Well that was the problem, my windshield fogged up BAD at a 1000 ft so I hit the breaks just before the 1/4. My time was 12.5 at 103. I need to look at the 1000ft speed to get a better indication of how much I scrubed off.
Run the vent on high (no AC!!!) when you run at night & it helps with the fogging.
Our 98 with 176,000 miles on it runs 11.30's with 3.42 rear, 4500 stall, mild heads/cam & ET streets for traction. 60' is 1.53 range. Only dynos at 330 rwhp w/convertor unlocked. So I'd say you have a pretty good combo now....just need to get the traction down.

How much money do you consider braking the bank? I would recommend a set of stickies. That would be the cheapest way to better your times. Also with the H/C swap a fast 90 or street warrior intake would help to get more power out of your current combo. The street warrior is supposed to be much cheaper than the fast and will be available very soon, this also gives you some time to save up. So maybe you can get tires and manifold. Because the added hp will not help at the track if you are not hooking.

Drag radials or better tires. No reason a heads/cam car with a stall and gears should not lay down at least a 1.7 60'
If your car is driven a ton, buy some used rims and have a set of track only tires. If you put less than 10,000 miles per year on your car, I'd buy nittos and run them all the time. They help a lot on the street too. Once a year you'll buy new rubber.

My experience with nittos was to drop them to 18 psi and heat the living sh*t out of them. Short heat cycle = 1.9 60'; burn them until I saw smoke in the rear view mirror = 1.7 60'.

What is you mph? You should be making plenty of power for a 11 sec pass. You don't need a fast intake. Get some good drag radials, BFGs or MTs and you will be in the 11s.
BTW where are you located? Altitude and humidity play a big factor.

Altitude is around 1400, but later in the year the relative pressure and heat can make it act like 3000
OK, What to do next? C5 Performance Like everyone has said, You need some sticky tires. It does not matter how much power you make if you can't put it to the ground. Depending on how serious you want to get you could (a) buy some drag radials and drive to the track or (b) you could buy a CCW drag pack and change tires at the track. Also the 3200 stall is hurting you too. You would be amazed at how a looser stall would help your ET, especially with the 3.73 gearing. Good luck. I used to have a 346 A4 with CNC heads and the same cam that you are using, LS6 intake, headers and 3.42 gear, but I had DRAG RADIALS and went 11.80@119.

Though Nitto's might not be that bad.
