What is the best psi to run nitto drag radials on the street and track?

I always ran mine at 25lbs on the street so the centers wouldn't wear out as fast, and around 17lbs at the track. I pulled 1.70 60's on 245-50-16 nitto DR's and 1.66 on 315-35-17 nitto DR's.

depends if your tranny/driveshaft/rear end is up for a high rpm launch.
the t5 will go BOOM

Totally depends on your mods, but going from the times under your user name I'm guessing you have just a few bolt-ons, and when I ran mine like that (I was running 14.3 at 97mph) I was launching at around 4000rpms if the track was sticky and I dropped my times to a 13.8 at 98.55mph. My 60's went from 2.08's on street tires to a 1.91 on the nittos. I have found that nittos do not like a quick dump of the clutch, rather they respond well to a quick slip of the clutch so as not to shock the tires into spinning. With my H/C/I set I was only lauching at around 3000-3500.
