In the continuing effort to maintain parity in the NHRA Pro Mod Drag Racing Series, the NHRA Technical Department is increasing the minimum weight for nitrous-assisted entries from 2,425 pounds to 2,475 pounds. The minimum weight for turbocharged entries will remain at 2,650 pounds while the minimum weight for supercharged entries will remain at 2,600 pounds. These rule changes will go into effect immediately. Additional parity adjustments will be made as necessary.
