1)I believe they are using all the NHRA factors. Only difference is the .3 index difference. If you ran any IHRA before they quit running class at their events, it was the same back then also. I haven't heard about their crate motor class's (alphabet cars). Let's hope that stays gone.
Zac and the Ross's was told this morning that the double car thing is not going to be allowed at National Events.

2)They are using the old indexes from NHRA. Back before they changed them. IHRA was this way before they disbanded Class racing a few years ago. Nothing new here, it's the way they do it. So just add .3 to everything from NHRA. NHRA 10.40 flat index, IHRA 10.70

3)No, the first crack at it they had a couple indexes wrong and Andy Kronenbitter and myself went up in the tower to get it corrected. IHRA uses NHRA indexes and adds .3 to them. They had some with IHRA, some with NHRA indexes. They were super tankful we told them and appreciated the help.
