It seems that in Pro Stock that dominance come in cycles, Bob Glidden, Warren Johnson, Darrel Alderman, Greg Anderson and now Jeggy. No one accused Greg of cheating when he set the record for most win in a season, or won back to back to back championships.
NHRA drivers and their teams are always pushing the limits of the rules, and when they find something that gives them more power or speed, they dominate until the other teams catch up. With the officials watching as closely as they are these days, true cheating, e.g. running nitrous, trick fuels, over size motors just doesn’t happen these days, in the old days yes, know no. If you call innovation and stretching the rules cheating, then almost ever team in NHRA is guilty of cheating.
