I have a set of the BFG drag radial t/a's.... about what pressure should i be running these at? and what is an average rpm to launch at for a pretty much stock a4 with a 373 rear?

Start w/18 psi cold at the track and leave at about 1200 rpm. Then experiment from there. Try leaving at idle,etc.

Dr's usually like anywhere from 18psi to 22psi

I run mine at 12 psi @ the track. I have a 4k stall and flash it and as long as there is a half decent prep I see fairly good 60', can't wait till I get a day thats warm enough for them to run full 1/4 instead of 1/8th.

Oddly enough, I've run my BFG DRs at 30 psi and have yet to break them loose while dumping the clutch at 4500. Admittedly, the slipping clutch is taking some of the shock away from the tires. But, I always like to start with the air pressure high, then work my way down to the highest pressure that will consistently hook. The car transitions nicely from the 60'-330' mark and feels a lot better in the traps with a little more pressure.
