Do trunk vehicles need an added metal bulkhead added to them if they have a fuel cell mounted in the trunk? Even if they have all factory seats and bulkhead in position?

Yes, rear seat is not the ideal bulkhead.

Read the rule book.

You got same answers from other site, are you looking for different answers or you simply don't want to install bulkhead per NHRA spec?

I came to a bigger site to get more input. Nothing wrong with that is there?

Does anyone have a link to the rule book online because i am yet to get a true answer just what people think the answer is so far..

I have seen and owned a few car with fuel cells in the trunk and this is the 1st time i have heard of this.. Have never given greif at the track before about it and hasn't came up until i showed pics of the trunk online so now i am trying to find the rules not speculation..

Found this..


Tanks:​
When permitted by class regulations, fuel tanks located
outside body and/or frame must be enclosed in a steel tube frame
constructed of minimum 1 1/4-inch O.D. x .065-inch chrome moly
or .118-inch mild-steel tubing. All fuel tanks must be isolated from
the driver’s compartment by a firewall, completely sealed to
prevent any fuel from entering the driver’s compartment. All fuel
tanks must have a pressure cap and be vented outside of car
body. A positive-locking screw-on fuel-tank cap is mandatory on all
cars. Insulated fuel tanks prohibited. When used, fuel cells must
have a metal box protecting the part of the fuel cell that is outside
of body lines or trunk floor, excluding hose-connection area in rear.

Non-metallic fuel cells or tanks must be grounded to frame.

No not really, but it certainly seem like you want to hear different answers.

You found the rule and it's not confusing. There is another rule about the same bulkhead being required if the battery is in the trunk. Just because some tech guy didn't bust you in the past doesn't mean much. All you need is a sheet of .024 steel or .032 aluminium behind the seat and under the speaker deck. All fuel tanks must be isolated from
the driver’s compartment by a firewall, completely sealed to
prevent any fuel from entering the driver’s compartment.

Shit, that solves it... I'm saving weight now. All steel panels are getting replaced by this new fangled fuel/fire proof vinyl.

Where might I buy such a space age material?

Pathetic is someone following someone around the internet forums over tech questions.. :smt039

Like i said the car has been this way for years and multiple tracks. Never heard of this until someone mentioned online the other day. When it comes to the rules it just says there should be a bulkhead barrier it doesn't say what it should be.. Granted metal one would be the best but further looking thru the rules You could use other materiels.


Firewall must provide a
bulkhead between the engine and/or fuel tank and driver
compartment. All openings must be sealed with aluminum or steel.
In certain instances, fiberglass, carbon fiber, or other composites
may be used. See Class Requirements or consult NHRA. Use of​
magnesium prohibited.
A Fire Blanket behind the factory seat on the inside might not be a bad idea..

Not sure why you seem so opposed to the rule but do what you want. You apparently haven't seen any race cars on fire in your racing experiences like I have. Fiberglas won't keep the flames away long and aluminium isn't much better. You got seats and carpet giving off toxic fumes, fueling the fire and you don't seem worried. Good luck with that if you catch fire.

No were did i say i was opposed to it. I was just trying to figure out the rules as i never heard it before or ran into this issue.. It is a wise thing to have and i can see that..

Do i want to do it no not really but i do want the car to pass tech any were i go. Granted it is a grudge car and most tracks i go to are laxed on tech that isn't the point.. As long as i can make it happen and keep a stockish appearance and not get rid of any of the factory stuff i will be happy..

This is the IHRA rule period, two choices .024 steel or .032 aluminum.
