Most racers can only afford to run one series, therefore they chose to run NHRA. Some reasons:
1. More NHRA tracks
2. More of their friends will be at NHRA races.
3. They don't like running 1/8 mile.
4. They aren't members of IHRA.
5. NHRA usually has the better tracks. Not true in Div. 4 I agree.
6. Racers are unfamiliar with IHRA classes so they are not comfortable running crate motor cars, pure stock cars, gt class cars, etc.
7. Even though only a few will ever win or runnerup the payouts are less. They feel right or wrong that the entry fee is excessive compared to the payout.
I don't believe however that reducing classes would increase attendance. Adding a Sunday time trial would increase attendance.
Adding more tracks will increase attendance.
Listening to the needs of racers will increase attendance.
Having seperate classes for the new cars will increase attendance.
If IHRA can attract more racers by treating the racers better or listening better than NHRA, as these racers become more familiar with IHRA, become members, establish friendships, etc. then the attendance will increase.
