Lot's of speculation regarding RPM's but it does not appear anyone has done their research.
The 482's on Keith's site call out a special grind Comp Cam hydraulic roller cam. I then looked at the Comp Cam site for FE hydraulic roller cams. Both sites list a maximum redline of 6200.
Please note that Keith does call out a "special grind", so it's possible that the 511 is higher, but if it is, I would not put it beyond 6500. It's the lifters that are the controlling factor.

A search for " drag racing practice trees " brings up a number of web sites, such as :
" Practice Tree, Full Size, 6 ft., Aluminum, 25 lb. Base, 40 ft. Cable, Lighter Adapter, 25 Watt Bulbs, Kit "
http://www.summitracing.com/parts/PTS-3100/

Anyone ever use ?
Not a drag racer, but is there different opinions on using the water box depending if using street tires, DOT drag tires, slicks, etc ?

One big issue with the water box with street cars is that the front tires then carry water with them into the staging area. If you are going to use the water box, then drive around it, and then back up into is to the front tires stay dry.
Remember, the front tires on drag cars are generally skinny.

The waterbox should not be used with street tires. You may burn all the water off the tires but you throw it up on the inner fenders to drip back down on the tires or track surface. If you're not running drag tires, you don't heat them that much, just spin 'em good to clean 'em off then go concentrate on the tree.
