Tuesday Tech Question presented by Evans Coolant



I was thinking about running my Super Pro Pontiac GTO in the NHRA Super Street class.  I heard somewhere that I would need to put a diaper on the car, is this correct?




Yes, in the 2019 NHRA Rulebook, Section 8 Super Street, page 2, Oil-Retention Device it reads “All vehicles must utilize an NHRA-accepted lower oil-containment device; may use a belly pan in lieu of a device attached to the engine.  If belly pan is used, must extend from framerail to framerail and extend forward of the harmonic balancer and rearward to rear-engine plate and must incorporate a minimum 2-inch-high lip on all sides.  A nonflammable, oil-absorbent liner  mandatory inside of retention device.”
