Tuesday Tech Question (06/25)

The Tuesday Tech Question is a fun section where prospective technical inspectors, or anyone who wants to get a better idea of how to work the NHRA Rulebook can test their knowledge and search abilities. If you have an NHRA Rulebook, try and find the answer to the question in the book before looking down at the answer. If you don’t have a Rulebook but are an NHRA Member, you can download a pdf at nhra.com under ‘Member Benefits’.



I am new to drag racing, and I am currently building a Super Pro Dragster.  I was told that the delay box must be NHRA Accepted.  How do I find what delay box is legal for my application?

Delay Box Dan,

A full list of all NHRA Accepted products is available on NHRARacer.com.  Simply navigate to the site, look at the column on the left and find the link labeled NHRA Accepted Products.  The resulting page gives you a link to the Accepted Products List as well as information as to how new products are accepted.
