positive reverse lockout device to prevent the shifter from accidentally being put into reverse gear. A functional neutral safety switch is mandatory. All transmission lines must
be metallic or high-pressure-type hose. All vehicles with engines running 4500 RPM or more and using an automatic transmission must be equipped with a transmission shield meeting SFI Spec 4.1 and must be labeled accordingly. A blanket-type shield is permitted; it must be appropriately labeled as meeting SFI Spec 4.1 and it must extend from the rear of the block to the front of tailhousing with a minimum six inch overlap where it is fastened. All non-blanket type shields must incorporate two (or one, per manufacturers instructions) 3/4 inch by 1/8 inch straps that bolt to the shield on each side and pass under the transmission pan unless the transmission pan is labeled as meeting SFI Spec 4.1. All vehicles with engines running 4500 RPM or more and using an automatic transmission must be equipped with a flex plate meeting SFI Spec 29.1 and be covered by a flex plate shield meeting SFI Spec 30.1.
Transmission, Manual: A clutch meeting minimum SFI Spec 1.1 or 1.2 is mandatory on all vehicles. All transmissions must be clutch assisted. Sequential shifters are prohibited. All vehicles equipped with a manual transmission must have a flywheel shield labeled as meeting minimum SFI Spec 6.3 or greater. Applications for which an SFI Spec flywheel shield is not available may use a properly attached SFI 4.1 or 4.2 blanket that completely covers the bell housing; it must be attached to the block and extend rearward to the transmission with a minimum six inch overlap where it is fastened.
Turbocharger: Vehicles are limited to two turbochargers only. Single turbos are unlimited. For multiple turbos, the inducer bore on the atmosphere compressor housing(s) may be no larger than 3.2 inches measured at the smallest diameter area
of the compressor wheel. A bushing may be used to downsize the compressor housing ahead of the wheel. If a bushing is used, it must be round, at least 3/4 inch long, mounted within 0.050 inch of the compressor wheel, and the inside diameter
of the bushing may not exceed the 3.2 inch limit. If you have any questions regarding the construction of a bushing, contact NADM Technical Services before the season starts. A stock map width enhancement (MWE) groove is permitted. No MWE groove may be wider than 1/4 inch. All provisions allowing air to the wheel other than via the bore and MWE grooves are prohibited. The inducer bore will be measured using a 3.25 inch plug.
Water Injection: Water injection is permitted. Alcohol, methanol, and all other flammables are prohibited.
Commercially available lube pump is allowed.
Wheelbase: The vehicle must retain the original unaltered factory wheelbase and track width. Front dual-wheel spacers may be used only with accompanying positive-offset dually style wheels
