Moving on, IHRA Crates, Pure Stock , 2018
 

Just a thought for those that will be racing some S /SS association events next year, maybe traveling to events out of your area. Some suggestions to help classify and prove your combinations engine, HP factor, Class designation, etc. This probably also applies to IHRA Stk/GT and IHRA S/S alphabet cars .....Remember the IHRA indexes are .3 soft so you may have to take an "adjustment" depending on the event rules..

Suggestion ,
Before IHRA deletes the class racer information pages, do this ASAP

Download and carry a copy of your combo's engine tech sheet.
Download, copy, and carry the current IHRA Stk and SS indexes.
Carry the latest (2017) IHRA rule book
Crate engines, download the current HP factor list, copy and carry

Helpful links , if your engine tech sheet isn't posted, contact Mike Baker @ IHRA
