All NHRA safety rules and Guidelines must be followed at all times for the SFWD Class. It is the sole responsibility of each competitor to ensure that their vehicle is in absolute compliance of any and all 2018 NHRA rules. OGS1320 class rules are solely for the purpose of insuring side by side competition and in no way shape or form supersede or conflict with NHRA safety rules and Guidelines. All NHRA safety rules and Guidelines must be followed at all times during the course of each event.
OGS1320 reserves the right at any time to inspect, seal for inspection, and/or tear down a participant’s vehicle. Every vehicle is subject to such further technical inspection at any time before, during or after an event, at the time and in the place and manner directed by an OGS1320 tech official. Not complying in full with any inspection request will result in disqualification for further competition and such other penalties as deemed appropriate by OGS1320 management.

**We reserve the right to adjust the weights to ensure side by side competition to any platform.
Engine swaps (e.g., B Series with B Series) permitted; however, OEM engine mounting points must be utilized. Engine swap (e.g., B Series to a K Series) permitted provided engine swap kits are commercially available and approved by OGS in advance.
Engine must be from same manufacturer as body. Engine must be overhead-cam, production-based design.
Maximum two power adders. Redundant power adders, such as a dual stage nitrous system, will be counted as one power adder. Engine must be in stock, transverse configuration.
Dry sump oil system or external oil pumps prohibited unless OEM equipped and engine is using complete OEM oiling system.
ENGINE CONTAINMENT DEVICE:
Engine diaper or catch-pan device to capture oil and debris in event of engine failure mandatory. Where exhaust header passes directly under oil pan, two-piece diaper may be utilized. FWD vehicles using OEM manual-transmission case must also have such a device for the transmission, to capture oil and debris in event of transmission failure. If catch-pan device is used, catch pan must employ minimum 2-inch-high lips on all sides. Lips must be coved or curved inward, so as to contain oil in pan. Catch pan must cover entire area below engine/transmission. Catch pan must extend from radiator support to firewall and from framerail to framerail. In all cases, lips must be adequate enough to contain oil in the catch pan.
Should a competitor spill excessive oil from the catch pan and debris onto the track, he or she may be disqualified from further competition at the sole and absolute discretion of the event director until catch pan is upgraded, regardless of height of pan lips or pan design.
SFWD racers MUST bring your own sealed cans of VP C85, VP Import, VP C16 and VP Q16 only. Fuel may not be modified in anyway. The use of addition additives is prohibited. Fuel Cell is allowed – but must meet all NHRA safety Rules. Methanol is not allowed. All competitors will be checked at least once and are subject to random inspection. Fuel samples will now be taken directly from the fuel rail. If you have a fuel sample valve that is NOT attached to the rail, then we will NOT be taking fuel from it. We will have AN wrenches available to the techs or you can provide your own at the time of the test to remove any lines in order to give sample. Accepted fuels must be readily available fuels, meaning they can be purchased by anyone. The fuels must not be modified in any way. You must use them the way they came from the fuel manufacturer. You will be disqualified from the race if you are caught using a fuel that is not approved or it is illegally altered in any way. We will be using a Digatron fuel tester to measure the dielectric levels of the fuel samples.
Before competition, competitors must declare which fuel will be used during the event and must not deviate from it throughout the event.
Injection of any other fuel is prohibited (e.g., methanol and or water injection). See General Regulations 1:6. Only one fuel container (ex: fuel cell or fuel tank) permitted. No water, methanol or any other kind of injection permitted.
Beginning at HDAY on 4/9/16 and 4/10/16 at Old Bridge Township Raceway Park, OGS1320 will require all SFWD racers to purchase their fuel for the event directly from the racetrack. SFWD racers will NO longer be allowed to use their personal fuel during qualifying and eliminations at all HDAY and BIG3 events. The fuel for the event will be owned by the corresponding track and we will guarantee that there will be more than enough fuel to last the entire event.
Fuel cell OK. NHRA guidelines MUST be followed. Must be in stock location or trunk area. No other container, fuel cell, bottle, etc. may contain any type of fuel.
