I usually run my drag radials at 23-25psi. On my old Firebird I got as good as a 1.53 60' with MT's regular DR's. On my Falcon wagon, I got 1.52 with the old Goodyear Eagle DOT drag radials (too bad they stopped making those) both in 275/60-15.
I'd usually do a quick spin in the water, pull out a few feet, tranny in low start the burnout, get to ~4500 and shift into 2nd, give it more throttle... watching the side mirror, I'd ease off the throttle when I saw the smoke start to get dense.
If the track isn't too busy, try a few practice launches before you stage. Don't go wild and piss off the starters, though! Start low, maybe 1200. If that hooks, try 1400,... different cars, different converters, different tunes... you just have to test to find what works best for you.
