Since the start of Project Valiant Effort, we knew it was going to be raced from time to time. With that plan in mind, we needed to make sure we could pass tech. The things we did to the Valiant are required for the e.t. at which the car is expected to run. There are many NHRA classes you can choose from, and Valiant Effort will not be traveling the quarter-mile faster than 11 seconds flat. After that, is it really a street-driven car? (I bet I'll get a lot of e-mails regarding that question).
For starters, you need to ask yourself: How quick and fast will I be going? NHRA has certain guidelines that each car must follow, and they base these guidelines on quarter-mile e.t. and mph.
If you want a complete list of NHRA rules, rule books are available for $12. If you sign up to be a member, a current rule book is included with the purchase of a membership. Contact NHRA Membership Services, P.O. Box 5555, Glendora, CA 91740-0950.
The first thing we did was decide where to mount the master disconnect switch. We wanted t

Everybody should know that if your battery is in the stock location, it must be securely mounted. No bungee straps are allowed. An easy way to aid in weight transfer is to relocate the battery to the trunk, where it's no longer adding weight to the nose of the car. When placing the battery in the trunk, it is usually placed over or behind the passenger-side wheel.
If you do choose to mount the battery in the trunk, it must be mounted to the frame or frame structure with a minimum of two 31/48-inch diameter bolts and a metal hold-down strap. The supplied J-hooks are not allowed. Also, the battery must be completely sealed from the driver compartment. This means a bulkhead must separate the trunk from the driver compartment. The battery can also be located in a sealed metal box, constructed of a minimum of .024-inch-thick steel or .032-inch-thick aluminum.
Moroso also offers an NHRA-accepted plastic battery box, PN 74050. Any car with a relocated battery must be equipped with a master electrical cutoff capable of stopping all electrical functions, including ignition. In other words, if somebody hits the master switch, it must shut off the engine as well as the fuel pumps and so on. The switch must be located on the rear of the vehicle, with the off position clearly marked. If the switch is a push-pull type, push must be the motion that shuts off the switch. Plastic or keyed-type switches are prohibited.
For our application, we contacted Summit Racing and got one of their battery-relocation kits, and Moroso sent us a disconnect switch and a long-arm conversion for mounting the switch inside the trunk.

Finally, there are other things we do to keep things safe during our day of racing. We always carry a fire extinguisher in the car. Don't just throw it on the floor to roll around and maybe end up under your brake pedal; fasten it securely. Even if you mount it in the trunk, you'll probably be able to get to it quicker than the fire truck can get to you if your car is burning. Don't try to race in shorts, a short-sleeved shirt, and a pair of Birkenstock sandals. No matter what your e.t., long pants, sleeves that cover your arms, and shoes are required.
A helmet is required if running 13.99 seconds or quicker. Yes, they check to see if it is properly rated. It is important to note that the helmet rating must be designated on a tag inside the helmet or sewn to one of the helmet straps. The designation stenciled on the exterior of the helmet is insufficient for NHRA technical inspection. Also, some tracks require all drivers to wear helmets, so check in advance.
