Do a Google search and/or just contact the NHRA and/or go visit your local NHRA track and talk to the officials. I robbed the following 2007 information from a Mustang news group....just for reference purposes.

NHRA changed the parachute rules for '08. It's now 9.99 or quicker, or 135 mph, whichever you hit first.
