I have a Super Pro ET dragster that I race at NHRA tracks around the country. At times I use nitrous oxide, and I would like to know if I can also use water injection?

Super Pro Stan,
Yes you can use an aftermarket water-methanol injection system. Per the 2013 NHRA Rulebook, Section 4A, page 2, Induction, “Aftermarket water-methanol injection systems permitted. Must be installed and used per manufacturer’s instructions. Tank, pump, lines, etc. may not be mounted inside the driver compartment. When located inside trunk a complete bulkhead of at least .024-inch steel or .032-inch aluminum is required to isolate driver compartment from trunk.”
