The highest RPM you can without spinning your tires. 
You won't know what RPM that is until you are there on the track on that surface and doing it. Really. There are too many variables. I would start at about 2000-2500 and go from there. Anyone that gives you a specific RPM that might work for them does not mean it will work for your combination and track conditions.

I had the all season TA KDW tires almost bald 225 wide on the rear of my 89 last year.
I would do a 5 second burnout to get them really hot and then launch at 2500 rpms at half throttle. Once the clutch catches up I would ease into the throttle until it was floored.
I got a best 60 foot time of 1.82 on 225 all season radials...lol
Swapped on my buddies ET streets 26 x 10.5 and launched at 5000 rpms and pulled a 1.6 60 foot with wheel spin.
On the street will be completely different, unless you prep the road.

BBK upper and lowers, springs, aluminum driveshaft and 3.55 ford gears, subframe connectors, welded torque boxes, KYB shocks with quad shocks still on there and a fully crapped out diff as you can see by the one wheel burnout action (this has been fixed see writeup).
My 88 leaving at 6000 with 26 x 11.5 ET streets, no wheel spin. Stock Z-T5, 3.73 gears, diff girdle, edelbrock uppers, SSM lowers, aluminum driveshaft, yukon 28 spline axles, torque box battle boxes, sub frame connectors, 8 point mild steel Comp eng. cage., 4 disk trac-lok.
Haven't had anything break at the track so far, knock on wood.
