I am installing a roll cage in a coworkers 71 Demon. He has installed a line lock under the dash, and routed the brake lines in the passenger area. Is that even legal per NHRA?
Thanks.

Hey Jeff, I don't know the answers to your question. But I do have a PDF of the 2013 NHRA rules somewhere in my computer. I could shoot it over to you via email if that would help.

---- "brake lines must be steel, steel braided, or DOT approved flexible and routed outside the frame rail, or enclosed in a 16" length 1/8" minium wall thickness tubing securely mounted where lines pass the flywheel bellhousing area and not routed in the driveline tunnel." Lines must be securely mounted per OEM style ---- this from the general section of the 2013 rule book. The big concern should be the bellhousing area ( don't ask me how I know  ). If possible, all lines should be in front of the firewall area excluding the one line to the rear brakes. For sure all lines passing the bellhousing area need to be enclosed. Keeping lengths and bends to a minimum is always beneficial.

outside the frame rails or enclosed in a steel tube?
how strictly is that enforced? what if your brake lines are 100% original as the vehicle left the factory? on my Dakota the rear lines travel along the inside of the frame tucked up next to the fuel line, which is also inside the frame.

I know there are guys out there who mount pressure gauges in the car for for setting a certian amount of brake on the starting line... so what whould be the difference?
I would feel better with a certian amount of brake line in the car myself vs being on the outside exposed to possible danger /damage. My old Dartsport I ran the rear line from the M/C to a grommet in the firewall and ran it right down the interior along the top of the rocker under the sill plate and back seat area. I used a longer brake hose from the rear end to meet up to the floor pan behind the rear seat brace. That way it was away from any drivetrain and protected from something on the outside damaging it.
When I redid the car, I ran the front pass side down the drivers side, along the core support and down the right side to the wheel. But being a stic k car, I was thinking safety from the bellhousing area. However, a front end accident could have damaged that easily too---so pick your poison.
I know it doesn't answer your question at all, but I think as long as it is done safely, no one is going to bother you --or him.

I would guess you are right - as long as there is something (floor, etc. ) between the brake line (s) and bellhousing and it is not in the tunnel area.
