I checked out your GT, the suspension setup is killer! NIce car.
The street tire times I have were from way back when I first bought this car. I went in the spring of 2002, and it still had the 3.08s in it, and the stock T body, but had the MAF, pulleys, subframes and stuff. I went 13.8 twice once at 99 and once at 100 MPH.
Then that summer I bought a Zex kit, and broke a 2.95 T5Z that I bought used and had just put in, like a month after

So the car sat all summer. Fall 2002 I bought a brand new T5-Z [current one] and went back on street tires [they were about bald] with the spray and still 3.08 gears & stock T body. And you are right its quite hard on a street tire because the car only went 13.66, BUT @ 110.9 something MPH sprayning 2,3, & 4 on the 100 jets. Stepped up to the 125 jet [I told myself I wouldnt]. Cut a nice 2.0 60' too, and then went to grab 3rd and the gas pedal got hung up on the floormat

and it stayed on the limiter for a second or two and I got it unhooked but it had bent my T body blade, and 1 plug looked like had started to melt

So, I only ever made 1 full run on the nitrous.
Sold the nitrous [was in wintertime who cares mode] bought the gears and T body this year, along with the slicks. And it runs what it runs now

Wonder what it would run with the nitrous back on.
