everything is fine with the car exept the drop tank
the engineer has no problem,with the mounting,or the quality of the tank.
he does not like the depature angle.everything below the tube shouldnt be there
does anyone in NSW, have this 120 litre brown davis droptank certifed by an engineer in thier car ?

If I was pulled up on the tank then I was going to try to argue that the drop tank fits within the departure angle created by the factory tank. Maybe get the engineer to talk to Brown Davis.

GML-31,i spoke yesterday to david brown at length.theres nothing he can do,and no certificate.u are on your own
darkone040,bought last year,$1400
the thing that shits me most about this,is the fact it goes up on a tilt tray no problem.
im willing to bet no ones tank makes it inside that angle.

I've also seen some very rough hatchet jobs on tanks to make them comply.
I was also of the impression that the Davis Brown tanks were certified, i remember reading it in their literature somewhere.
I think it comes down to the individual engineer.....& their interpretation of the rules.
Let's face it....these tanks have been fitted to registered cars in every state of Oz....& certified!
This was passed in Qld [strictest state for compliance] a few weeks ago.
Good luck m8!

alter the departure angle by fitting a towbar!
PS love the car looks alsome and the way you have built it should be a real fun drive

And fit some higher springs to the rear end so the wheels are lower in relation to the tankalter the departure angle by fitting a towbar!

I think Brown Davis have certification for the fabrication not the instalation.
From the info I think you need to be able to demonstrate that the exhaust is used in the interpretation of the lowest and rearmost extremity of the OEM permanent body work.
As other's have said it will come down to the interpretation of your engineer regarding his willingness to certify the modifications.

Original Equipment Manufacturer's (OEM) permanent body work
It would be helpful if someone with a single system and standard tank could post a picture showing if the standard tank does or does not fit within the departure angle.
If the standard tank does not fit within the departure angle then you may be able to use the angle created by the standard tank for the drop tank.

Just done some simple and very rough calcs. As it is, its only about 7 degrees out but it would need to be raised by 3.4 inches. Only drama is that as the car goes higher so does the rear bodywork.

A fuel tank is not "permanent body work".Judging from the angle difference of the tank and the bar i dare say they designed it to fit to a torana that sits higher in the rear than yours. I would have thought the fuel tank would be considered a permanent part of the car. If you take yours off to go to the shops then your doing better than me....
I think the previous post is the simplest, ie higher springs.
Even if it was a monster truck the tank near the beaver panel would not be inside the angle. It is this point on the orginal tank tank I am not sure fits within the angle.

Standard rear springs, standard tank.

Otherwise I think the solution is a more understanding engineer.
They all have the same rulebook,but some read it differently to others.

It is a very subjective matter and relies upon the interpretation of the regulations by the engineer (abit like lawyers).
Some engineers will pass a drop tank and some will not.
The rebuild of this hatchback is of the highest quality and I personally know the owner and have inspected the car.
No shortcuts have been taken and cost has never been a factor.
In my opinion this car is 100% legal and hopefully things will work out.

Engineer said nothing about my tank departure angle, but we didn't mesure the angle either.

I will talk to my engineer tomorrow however as far as I can see there is no wiggle room in the NCOP which is used in WA.
The engineer is required to answer each item on checklist LM1. Question 1.7 on page 10 asks if the tank is within the departure angle.

A few years ago (before i owned it) my car scored a new custom made fuel tank for this very reason. It's 100 litres, custom made by Performance Metalcraft.
The engineer would not pass the old tank. The current one is said to fall within the departure angle, and is certified in NSW.
Cheers
