1/4 mile advice needed
Ok, here's the situation I just bought BFGoodrich G-force T/A Drag radials. I was wondering what PSI I should run it at...it says 44 PSI On the tire, but that's wayy too high...I think, right? I was thinking running them at 25...The elevation out here is 2700 ft... I also would like to know if I should burn out in or out of water, I've been told to do one and the other by different people. I also wanted to know what I should rev to before launching Im on an Automatic and I dont have a Torque converter, Just a VARAM and Exhaust thanks for all the help to come, I also launch it in 3rd, correct??

As far as the drag radials, roll slowly thru the water, then pull up a few feet past it. Then do your nice, smokey DR burnout.
NEVER EVER do a burnout IN the water. You'll throw water everywhere & when you get to the line, you'll sit & spin.
I'd also lower the psi down to 16 or 17 & adjust up from there.
The psi on the tire is usually the max psi allowed for the tire.
Hope this helps!

Definitely do the burn out and drop the tire pressure to 16-17psi (you can start a little higher if you like, but 25 is way too high).
As for launching the auto, get the RPM's up as high as possible and then floor it on the third yellow.
Having a higher stall converter will help a lot, as you can launch at higher RPM.
And yes, it is correct to launch in 3rd

I would do the burnout with T/C off, stage, put it in 3rd, bring the revs up to load the driveline and then back to no more than 1K rpms.......WOT on green
What size Dr did you buy?

Fujikura, you have some good advice already. Only other thing I would recommend is checking out the Corvette Challenge at LACR as that will give you exposure to other Corvette drivers in your area

In either gear, just bring the revs up to 5300, dump the clutch & quickly get on the brakes, but only enough to hold the car from moving...You'll move froward a few feet until you hit the brakes, but don't panic.

You can lightly touch the brake in order to keep the car where you want it. Now completely remove your foot from the brake and roll out of the burnout.
