Question:

I have a 1963 Ford Falcon Super Pro ET car that I race at my local NHRA track.  I want to know if aftermarket water-methanol injection is legal to use with my nitrous oxide system?

Answer:

Yes you can use an aftermarket water-methanol injection system. In the 2019 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.”
