Tuesday Tech Question

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 Rulebooks can test their knowledge and search abilities. If you have an NHRA Rulebook, try and find the answer the 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’m having a clearance problem with my SFI 30.1 flexplate shield. Is it legal to cut and notch my steel flexplate shield so it will fit better?

Flexplate Flipper,

No it is not. In the 2013 NHRA Rulebook HOW TO USE THIS RULEBOOK section on page XV close to the front of the book it states “Under no circumstances may any certified product be modified, altered, or in any way vary from the “as manufactured” condition. Such practice is in violation of the SFI, Snell, DOT, etc. program, voids such certification and therefore will not be accepted by NHRA.”
