What kind of street tires were they? Damn, I thought when I pulled a 1.819 on the stock 235/55/17 pirelli all seasons was good.

OP, you can't expect the world your first time out on DRs, its going to take practice to figure them out. How many times did you go to the track before you got the DRs? Consistent practice is the key to pulling good ETs.

They are yokohoma advana, these things have blown my mind how well they do everything. Its only a 245/45/19 so its not like I have a massive contact patch.

He can get it done, just takes practice like we've already said.

That is pretty bad for drag radials. I had a better 60 foot by leaving at idle with drag radials, but I have a little more power. A little spin is better than bogging.

If you cut good lights disregard this post

Remember that your time dose not start until you break the beams so just because someone else has a car that can run 13 flat and yours might run 13.5 you can still beat him to the finish line if the difference between your launch and his is 0.51 seconds. ((you win))

pay attention to your reaction time. You will be way ahead of the game if you can consistently cut a great light. I don't know what kind of tree light you race from but if it is the one that lights up 3 yellow like 1..2..3..green then pay attention to the 3rd yellow . I mean watch it as if it is going to try to kill you and you have to take off as soon as it barely starts to glow to save your life.
Don't take off on the second and don't anticipate the 3rd yellow too much or you may red light. What this dose is when the 3rd yellow comes on your brain is reacting on yellow but by the time you move your feet and the car actually starts moving the light will be green and no red light. If you wait until green you have already blown it. It takes practice but worth it once you figure out your car . Also try to stage the same way every time . an inc or two can give you inconsistent results.
A pro tree is almost the same method but all three yellow light are ready to kill you all at once. get pumpt and be on high alert . I also like to punch the air and yell and throw my body back in my seat all at once when I launch

i know. next time, i am going to have the tires at 18psi, and launch hard from 4500 rpm, maybe 5000.

2.1 is a bad #. i hate it. i want to kill it!!

you need to cut about 1 second off that reaction time at least . you can do it
a perfect light is 0.500 to 0.400

link to reaction time article I found

with your 1.9 reaction time someone could beat you with a one and a half second slower car if the cut a 0.400 light

I have cut a few perfect lights with a very slow car with skinny tires that spin . the key is knowing your car and how long it actually takes it to move forward. also be sure to stage the car the same way every time so you can get a reference point.( some tire wheel setups allow for over a few inches to play with because it blocks the starting line beam more than some tires due to tire diameter and the psi of the tire allows more tire to touch the ground .)

Prime example, just watch the first run of this:

That was my first time ever at the track, oh the lessons learned
