SECTION 20: GENERAL REGULATIONS, ENGINE: 1, 1:3 EXHAUST (Page 3)

All cars vehicles must be equipped with exhaust collectors, headers, or stacks installed to direct exhaust out of car vehicle body to rear of car, away from driver and fuel tank. No part of the exhaust system may be routed through the driver’s compartment. Exhaust collectors/stacks system components must be securely fastened (i.e., metal connector straps, bolted, welded, etc.) to prevent loss of collector/stacks system components during competition. Effective Jan. 1, 2014, All removable multi-piece exhaust collectors/stacks must be securely fastened with either an NHRA-accepted header tether, or a minimum ½” (half-inch) stitch weld located on each primary tube or be permanently attached to the vehicle body or frame with positive fasteners (i.e. exhaust hangers, support brackets, bolts/nuts, etc.) such that they require tools for removal. to prevent loss of collector/stacks during competition. A current list of NHRA-accepted header tethers is available on NHRARacer.com. Flexible tubing or “flex pipe” prohibited in all categories. If mufflers are used, they must be securely attached to exhaust system and car vehicle body or frame.Consistent with its endeavors to maintain drag racing’s acceptance as a recognized sport and recreation, NHRA is enforcing maximum decibel levels for Super Street, Super Gas, and Super Comp vehicles competing at national events. NHRA may enforce the same or similar requirements on other categories in the future.

SECTION 20: GENERAL REGULATIONS, FRAME: 4, 4:8 PARACHUTES (Page 19) If outlined in Class Requirements, it is mandatory to have a braking parachute produced by a recognized drag racing parachute manufacturer. Dual parachutes required for all cars running 200 mph or more or if required by Class Requirements. Tech inspectors may observe the proper operation of the parachute(s) and inspect for worn or frayed shroud lines, ripped or dirty canopies, and worn or ragged pilot chutes. Parachute cable housings should be mounted solidly to frame tube or other suitable member no farther back than 1 inch from the release handle. If automated push-button release system is used, driver must also be able to use handle to manually release the parachute(s). The release housing must be attached within 12 inches of the parachute pack and in a manner that will allow the inner cable to release the parachute. When supercharged or using nitromethane as a fuel, it is mandatory that the parachute pack and unpacked shroud lines be protected with fire-resistant material from the mounting point to the pack. Parachutes must have their own independent mounting with sleeved 3/8-inch minimum steel bolts or steel pins required for all applications unless otherwise stated in Class Requirements. The use of ball-lock pins for parachute mounting prohibited. Applications using two parachutes are required to have separate mounting points for each parachute system. Shroud-line(s) mounting brackets must be constructed of minimum .090-inch steel unless otherwise stated in Class Requirements. Safety pins must be red flagged and removed prior to burnout. The use of ball-lock pins for parachute mounting prohibited. See Class Requirements regarding use of two parachutes. Such applications required separate shroud-line mounting points for each parachute system.

SECTION 4A: SUPER PRO, PRO, SPORTSMAN, ELECTRICAL: 8, DELAY BOX/DEVICE (Page 7) (12/11/2013) Permitted in Advanced E.T. and Super Pro only. Pneumatic starting line enhancers are permitted in Advanced E.T. and Super Pro only.

SECTION 4A: SUPER PRO, PRO, SPORTSMAN, ELECTRICAL: 8, IGNITION (Page 7) (12/11/2013) Timed ignition-interruption devices (stutter boxes) prohibited. Starting-line and/or high-side rev limiters permitted. Two-steps, rev limiters, or any other rpm-limiting devices, legal unto themselves but altered or installed so as to function as a downtrack rpm controller, prohibited. The wire to the transbrake (or line-loc) may contain a splice that activates the two-step/launch-control device in the ignition system. No other wiring shall be connected directly or indirectly between any other part of the ignition system and the delay box/device. All wiring associated with the ignition system must be fully visible, labeled, and traceable. See General Regulations 8:3.

SECTION 6A: TOP SPORTSMAN, ELECTRICAL: 8, DELAY BOX/DEVICE (Page 4) (12/11/2013) Permitted. Two-step accepted for starting-line use. Downtrack throttle stops, electronic ignition interrupters (stutter boxes), or use of pneumatics are prohibited. Pneumatic starting line enhancers are permitted for all applications. One delay box/device is permitted; it may be attached to the transbrake, and/or shift timer only. The wire to the transbrake (or line-loc) may contain a splice that activates the two-step/launch-control device in the ignition system. All wiring associated with the delay device, ignition system, automatic shifter, tachometer, data recorder, and fuel-injection system must be fully visible, labeled, and traceable. Delay devices and associated components (such as transbrakes, automatic shifters, data recorders, tachometers, fuel-injection system, etc.) must be utilized in an unaltered manner consistent with the manufacturers installation and instruction books unless otherwise approved. Any ignition system tachometer function or any other rpm function is prohibited from interaction with the delay device on any car that uses a pneumatic starting line enhancer. See General Regulations 8.2.

SECTION 6A: TOP SPORTSMAN, ELECTRICAL: 8, IGNITION (Page 5) (12/11/2013) Aftermarket electronic ignition boxes must be used unaltered from factory specifications. Timed ignition-interruption devices (stutter boxes) prohibited. Starting-line and/or high-side rev limiters permitted. Two-steps, rev limiters, or any other rpm-limiting devices, legal unto themselves but altered or installed so as to function as a downtrack rpm controller, prohibited. The wire to the transbrake (or line-loc) may contain a splice that activates the two-step/launch-control device in the ignition system. For supercharged and turbocharged applications also see the Delay Box/Devices paragraph. All wiring associated with the ignition system must be fully visible, labeled, and traceable. See General Regulations 8:3.

SECTION 7: SUPER STREET, ELECTRICAL: 8, DELAYBOX/DEVICE (Page 5) (12/11/2013) Permitted. Prior to use, all delay boxes/devices manufactured after Jan. 1, 2003 must be NHRA-accepted. A current list of NHRAaccepted delay boxes is available on NHRARacer.com. One delay box/device is permitted; it may be attached to the transbrake, shift timer, and/or throttle timer only. The wire to the transbrake (or lineloc) may contain a splice that activates the two-step/launch-control device in the ignition system. No other wiring shall be connected directly or indirectly between any other part of the ignition system or any other devices (such as data recorders, tachometers, suspension components, fuel-injection system, etc.) and the delay box/device. All wiring associated with the delay device, throttle-stop timer, ignition system, automatic shifter, tachometer, data recorder, and fuel-injection system must be fully visible, labeled, and traceable. The rpm-based automatic shifters that are incorporated into some delay boxes/devices may not be used for any purpose. The built-in tachometer that is incorporated into some delay boxes/ devices may not be used for any purpose. Delay devices and associated components (such as transbrakes, automatic shifters, throttle-stop timers, data recorders, tachometers, fuel-injection system, etc.) must be utilized in an unaltered manner consistent with the manufacturers installation and instruction books unless otherwise approved. Delay boxes/devices, throttle controllers, automatic shifters, etc. that provide on/off indications (based on time and/or rpm) may be located within the drivers view. Only those throttle-stop, automatic-shifter, etc. operations actually being used may be indicated. The use of any other visual, audible, etc. indications that are transmitted to the driver in any form that provide on-track data are prohibited. See General Regulations 8:2.

Updates Following the NHRA Division Five Meetings - If SFI Spec 3.3 neck collar is required and driver opts to use head and neck restraint system instead, then SFI Spec 3.3 head sock or SFI Spec 3.3 skirted helmet mandatory. - NHRA Division Five has updated rules for their Sportsman and High School classes at the NHRA Summit Racing E.T. Finals. Two-Steps are not allowed as a starting line RPM controller. Bandimere Speedway will implement this in our points categories of Run Tuff, Street E.T., Street Sport Compact, High School, Top Street (Club Clash), Hot Rod (Club Clash), and Fall Trophy. These are all classes that already did not allow transmission brakes. **UPDATE\from Bob Blackwell - "I got a little better explanation, we are still going to continue to allow the pneumatic starting line cylinders to be used. It will count as one rev-limiter for the car. They can be used in Pro ET."
