I don't run NOS however I've considered adding two 150 plates at times for a simple, up to, 300 shot.
My tunnel ram used to have two 850 alcohol carbs on it but I've switched to a Ron's Flying Toilet system. I now have two 4.1" (3600 total CFM) toilets sitting on an Edelbrock 2R tunnel ram feeding a 540. After running injected alcohol, I'll never go back to gas or carbs on a race engine.
I don't really care about specific classes like "drag radial". I currently have 32 x 14 slicks and want to put on 32 x 16's. The big tires hook up so much better on poorly prepped tracks. My sig picture was taken on a Friday night street legal race. I was just getting some track time for tuning. On Friday nights, there usually isn't much track prep and the street tire cars are always spinning off the line. I carried the front wheels about 40 feet on that pass.
