Rear Firewall Question

Unless they recently changed the rules you don't need a rear firewall for the battery if you use a NHRA approved sealed battery box vented to the outside. Fuel cell in the trunk is a different story.

You are correct. My car's got a trunk-mounted fuel cell though, so I'll need a rear firewall regardless.

I'm going to shoot an email to our NHRA division tech director. I'll let you all know what he says.
