The NMCA manufacturer's midway at Bowling Green was a great place to get knowledgeable tech advice from the folks at Holley-which is exactly what Shawn Zubler (Newtown, Pennsylvania; left) is getting from Holley/NOS sales rep Kyle Smith. Kyle is explaining the benefit of NOS's new "Launcher" nitrous management system, which Shawn plans to use for a new radial-tire class car he's building. Shawn likes the Launcher's progressive control-perfect for the traction-limited class he's planning for, plus the data-logging feature he needs for proper fuel control and fine-tuning traction. The Launcher starts around $400 for a laptop-based system, but a handheld controller version is available for around $600, and a full-blown LCD touchscreen version for $800.
