BF Goodrich Drag Radial Tire Pressure

Hi Guys
I've just started racing my 73 duster. I run 165 radials on the front with 36psi. My question is I'm running 275/50/15 Drag Radials on the rear, a good friend of mine said I should run 24psi. Now I've been looking through the forum and everyone goes from 14psi to 22 psi..I'd like to get my 60 foot times down at the moment it about 1.9..
Any help greatly appreciated
