Start by setting them at 17 PSI and working down. You probably won't want to go any farther than 12 or 13 though. The lower you go the more top end sway you will get up top (Normally). Do a decent but short burnout on them. That's all you need. Once you get them where you got them hooking good, You'l want to be generally within 1 - 1 1/2 psi about anywhere you go for the most part. You'll just have to work with them on a test and tune day when you have time. Best information I can give you. BTW, once they've got a few runs on them they generally hook better if they are new to begin with. Just some things to try and keep in mind. Later
unless you are making insane amounts of horsepower with them only require going through the water box, barely getting wet, turning them enough to clean'em and get excess water off, then stage. When I run mine they hook really well and I run the tall 275-60-15 (27.7 -28" tall) BF Goodrich drag radials. 60' times range in the 1.80's - to Low 1.90's. Best has been a 1.79. To answer your questions yes I leave the line under full throttle, with the stock convertor @ about 1500 RPM's. I keep the data on every run I make so I KNOW what I changed or did to get what I got as far as 60' and e.t. When you start doing that you will run more consistent and know what changes are working and what are not. In the NMRA racing series some of the Drag Radial ONLY class cars are running low nines or high 8's on street tires to give you the idea of their capabilities. Just some information to digest. Let me know how it turns out!!
Have a 96 Cougar XR7 with the 15 inch wheels (Factory). Not exactly the best set - up for running around town on) but they do. They are hell on the track though. When I'm not running the big Drag radials I usually run 245-60-15 BF Goodrich T/A's.
