Tuesday Tech Question


I just purchased a center-steer altered that ran 7.70 in the ¼-mile and I will be putting my blown small-block Chevy motor in it and I think it should run about 7.0 in the ¼-mile.  I was told that I will need to cover the seat with flame-retardant cloth.  Is this something I will need to do?

Covered Seat Carl



Covered Seat Carl,

That is correct.  In the 2012 NHRA Rulebook in the Advanced ET section 4B, page 11 it states “For all front-engine open-bodied vehicles supercharged or turbocharged (gasoline- or methanol-burning), a flame-retardant material-covered seat is mandatory.”
