COBRA207

Can anyone tell me what the rule's are with blower's and the like protruding through the bonnet of car.

I ask this as I'm thinking of building a Mad Max pursuit special Rep (XB Coupe) but I'm not sure what the rule's for the blower are.

What I would like to do is have a real blower fitted to the car and not a fake like the one in the Mad Max movies.

Cheer's

Nathan.

This comes from a Vicroads information sheet, but will give you an idea of the requirements (last updated June 2002).

14. BONNET SCOOPS AND PROTRUSIONS

A bonnet scoop or cover may be fitted to a vehicle provided:
• It is of a type offered by the manufacturer of the vehicle as an option for that model or series; or
• It is constructed so that all edges and protrusions are suitably radiused and there are no single openings larger than 4000mm2 (equivalent to a 65mm circle) towards the front of the vehicle; and
• It permits the driver to have a clear uninterrupted view, through the full width of the windscreen of all parts of the road surface 11 metres forward of the steering wheel viewed from any driving position permitted by the range of adjustment of the driver's seat; and
• When a 165mm diameter disc is placed on the bonnet in front of the scoop or bonnet projection and rolled rearwards until it touches the scoop, no point of contact between the disc and the scoop or bonnet projection shall lie above a horizontal plane passing through the centre of the disc; and
• No metal, engine mounted component, likely to increase injuries to any person may project through and above the bonnet profile without being protected with a cover mounted on the bonnet and complying with the above requirements.

Thank's outback, I guess that rule's out building a Max replica.

Check locally Nathan, I’ve seen pics of a few blown street-reg cars from Qld. Not sure if they’re legal though. Ask the Qld version of the RTA.

DGROMS.com

But doesn't this only apply to vehicle made after the release of these rules. I think you might find that the vehicle would only have to apply with rules for when it was made

Out of interest does anyone know the rules for how wide you can have your tyres (esp for a XA-XC coupe)?

Thank's again for your help guy's I'll hit up Main Road's (QLD RTA, I think??) and see what I can come up with.

In WA the maximum that you can go is one inch above standard. The widest that the coupes came out with is 7 inch rims, therefore max is 8 inch rims. With respect to tyres you are simply looking at what is legally allowed on those rims. I think (will stand corrected) that the max on an 8 inch rim is 255-265 tyres.

Personally though, the coupes simply look wrong if you don't have 295's on the back. I have got the 295's on 15*10's on the back and 15*8s with 265's on the front. Not legal though!

Bonnet Scoops

Bonnet scoops/projections may be fitted to any vehicle
provided the driver’s vision is not restricted under normal
operating conditions with the driver’s seat located at its
lowest and rearmost position.

Bonnet-mounted scoops/projections must meet the following
requirements:

• When a 165mm diameter sphere is placed on the bonnet
in front of the scoop (or bonnet projection) and rolled
backwards until it touches the scoop, no forward point
of the scoop or point of contact between the sphere
and the scoop must lie above a horizontal plane passing
through the centre of the sphere.

It shall be possible to see either the surface of the road
11 metres in front of the driver’s eye or all of the front
edge of the original body when looking across the top of
the bonnet scoop. For the purposes of this requirement,
the driver’s “eye” position can be taken as being a point
730mm above and 270mm forward of the junction of the
seat cushion and seat back with the seat in its lowest and
rearmost position.

The edges at the front of a scoop/projection shall
be rounded with a minimum of 10mm radius.

• All other edges and corners shall have a radius of not less
than 5mm and be designed to reduce the risk of bodily
injury to any person to a minimum.

• The scoop/projections must not have reflective surfaces.

• Any holes in the bonnet must not substantially reduce
the strength or impact resistance of the bonnet.

• Air cleaners or carburettors must not protrude beyond
the original bonnet profile unless the bonnet scoop/
projection is manufactured from equivalent gauge mild
steel, compared with that of the original bonnet.
