Default Pointers for the drag

I plan on getting to the track ASAP. What are some things that I need to do in order for me to get the most out of the car. i.e. turn off traction control? shift with paddles or just gun it? power brake? turn ECT power on? lower rear tire psi to what?

i have a 350.

thanks for any help

1/4 tank of gas, power mode, and punch it. then try with vdim off. Results will vary based on track condition, as many are repaved in off-season.

Reaction time is a big factor - nail it when the tree gets to the last yellow.

Do a big burnout at first so the crowd cheers, then when you run a high 14 second 1/4 mile caused you messed up your launch/reaction time the crowd will only be half dissapointed.

I am going to the track tomorrow also to see what I can do.

Actually from my experience at the dragstrip you'd be better off driving around the burnout box and skipping the burnout altogether if you want your best time. Street tires just don't work well hot. If the track is really dirty while you're in line, then I'd go in front of the burnout box and do a quick jack-rabbit start to clean the tires. At places like Maple Grove, I never even did that. Some people lower the rear tire pressure a few psi and raise the fronts 5 psi below the max psi of the tire, but I never found much difference in my times. Now if you run drag tires that all goes out the window.

Reaction time doesn't effect ET.

I didn't even see that, you're absolutely right. On my very first attempt down the 1420 I was so hyped up about the tree I TOTALLY screwed up my launch. Most people are concerned with the ET and MPH, RT is just something to bust on your friends about... so unless you're competing with someone forget the tree until you have a few runs under your belt.

I just got back from the track and here are my learnings (of course, there are different variables at different tracks). My 350 is stock with an intake.

- VDIM off
- ECT PWR on
- spare tire/jack and winter mats (trunck and summer mats too) out
- hold car and launch at ~1500
- rear tires at 29psi
- front tires at just under max
- tranny in D
- don't burn out (unless you get some water on your tires or for a photo op)

I think that's it... just mash the gas and some 13 seconds later, it's all done.

Here are my track experience and results:
