Behind the passenger seating area is the generously large 12-gallon reservoir for the supercharger intercooler. John figures a larger tank of wateractually ice at the beginning of the racestays cooler longer. A separately switched pump controls coolant flow and is not turned on until after the race starts. Also notable are the massive, double-tube seat mounts. Such substantial mountings are good insurance against high-speed, multi-flip accidents that can fail lighter seat hardware.
