Houston Raceway Park - helmet usage
Guys,
It's been quite a few years since I've been to HRP. The last time I was there, I was running a low 13 second LT1 car and I didn't bring a helmet; I wasn't thrown off the track at the time It's been several years and the 5th gens are now running faster than that bone stock. My question is, how is HRP with regards to enforcing the helmet rule? If memory serves, NHRA requires a helmet in cars that run 13.99 and faster. Is this enforced more strictly than it was years ago? Thanks |

13.99
NHRA requires a DOT, SNELL or SFI helmet for any car quicker than 14.00. There are a number of different specs so you should check with your local tech inspector. For cars that run e.t.’s between 12.00 and 13.99, all of the above requirements apply along with the addition of a driveshaft loop. A new-for-’95 rule exempts cars running 13.00 and slower when equipped with street tires. Since traction is the key to going quick, this places more strain on the driveshaft. To prevent the driveshaft from breaking at the front U-joint area and perhaps coming into the interior of the car, or digging into the track and pole-vaulting the car, NHRA mandates that a steel loop be placed just behind the front U-joint of the driveshaft. A universal driveshaft loop is available from Lakewood that bolts to the floorpan. A rollbar is required in this e.t. bracket only if the car is a convertible. 11.99 By the time a car is capable of running between 11.00 and 11.99 seconds in the quarter-mile, safety requirements are especially important. Up until this point, factory seatbelts are acceptable, but in the 11-second-and-quicker time zone you need a quality safety harness. The minimum requirement is a 3-inch-wide, five-point harness meeting SFI spec 16.1. The 1995 National Hot Rod Association Rulebook outlines the proper way to mount the shoulder harness and belts. An NHRA-legal rollbar is also required in the category. Recent rule changes have reconfigured what NHRA classifies as a rollbar. The classic four-point bar is no longer acceptable. The new standard is mild-steel tubing of at least .120-inch wall thickness (most chassis companies, like Art Morrison, use .134-inch wall tubing) that includes a forward-running side bar from the main hoop past the driver’s shoulder. This bar is only required on the driver’s side, but most systems include both sides for a six-point rollbar. An SFI-approved scattershield is also necessary in this e.t. category. NHRA requires the scattershield to have an SFI aluminum-foil sticker. According to Red Roberts of McLeod Industries, older bellhousings can be certified by sending the scattershield and block plate to the original manufacturer. The company will inspect the housing and if it passes, it will receive an SFI 6-1 certification. Most SFI certifications are good for five years. Contact your manufacturer if you’re not sure. The clutch and flywheel must also be SFI certified. The main consideration in this area is to avoid using a cast-iron flywheel. According to Roberts, sometime in the mid-’70s most of the new car companies began using nodular iron flywheels that are much safer. Most, if not all, current high-performance aluminum and steel flywheels are safe when used in conjunction with an approved scattershield, but the rules state that the pressure plate and flywheel need an SFI certification number. Roberts says the best plan is to record all your SFI numbers in a logbook. This makes it easier for the tech inspector and it shows the inspector that you understand the importance of the inspection process. This e.t. level also requires steel valve stems in all wheels, along with arm restraints for open-****pit cars like roadsters.

Only someone from RPR could tell you that.
If you have a mishap you would be glad to have the required safety equipment. It is a requirement for your protection.
