Bonnet scoops: Is it still the rule that if you can see the front of the left hand corner of the bonnet its a legal height??

Exhaust: Can it be dumped at the diff??

Engine size: Can i fit a 400 small block into my HJ Premier or a 454 big block??

Wheels: is there a rule as to how much difference between front and rear wheels size?? as in i want some 15x8.5s on my rear and 15x4 on the front?? is there a actual dimension??

Air cleaners: can we poke a air cleaner through the bonnet even if its only 3-4cms??

Racing harnesses: can 4point harnesses be bolted to the floor directly behind the drivers seat and still allow passengers behind in the car

Noise level: How noisy is too noisy??

Heater: Can i remove the heater completely and replace it with a flat metal panel??

That should do for for now... any help on these matters will be greatly appreciated

theres a few answers here.

probably no to most of them though buddy.
yes to the 400 with a mod plate, no to the air cleaner, no to the dumpers (i got em but)
no to the harnesses (90% sure) heater yes, if replaced with a heater of some sort, and a bit sketchy at that. and I think over 98 decibels is too loud.

not looking for a big block chev any more!!

i hope i can help

1 the bonnet scoop has to be or have a point of contact under 8 cm. anything under that is fine if you look at the dot book it gives the guidelines any reverse cowl scoop will be fine and height isnt an issue becuase point of contact will be under 8cm. any drag hornet scoop will be illegal, basically the really flat looking hornet scoop sold from autobahn will be ok
2 exhaust has to be full system and meet the adr compliance for noise limit of your vehicle so if your running a big block two mufflers or resonators are going to be needed ( previous experience with hq and a big block with twin 3 in exhaust)
3 hj from memory never had the 350 (sorry if am wrong) so will be hard as the 308 was the largest cu in engine. However a 400 will not be a problem 454 might be but the car will need to be mod tagged for both the larger capacity engines. speak to an engineer and see what they say shouldnt be an issue though
4 yes there is an actaul measurement for the tyres but i cant remember it sorry will have too look into that one. you will have issue's running a 4in tyre on the front boys in blue will eat you alive for it i have them on my vk and get nailed all the time with them
5 yes you can have the aircleaner through the bonnet as long as the bonnet is reinforced and structurally sound and it will need to be covered by a bonnet scoop the boys in blue will get you for that one as well even though there are alot of cars out there doing the no bonnet scoop thing
6 racing harness should have the rear straps not mounted to the floor behind the seat. they should be between a horizonatal and 45 degree angle. if you want to have passengers in the back you may need a half cage with a taxi bar so the harness can be mounted to it. if that is not an option then the harnesses will need to go to the parcel shelf or betwen the back seat and meet adr compliance. the harnesses will also need to be mod tagged for dot and street use and if the cage is not used and the harnesses are permanent the car will be need to be registered as a two seater
7 noise level has to meet the noise level for your year vehicle and shoild be no more than 96 or 98 db
8 the heater im not sure on mate but the boys in blue if they want to be picky could get you for not having your accessories working as you have changed the vehicles original configuration

Another question.. Are butterfly scoops legal in QLD???

wabbit

no no no no no

not a chance.
assuming you mean sticking out of the bonnet

no part of the engine or induction system may protrude through the bonnet unless covered by a scoop made of equivilant gauge mild steel........or words to that effect.
also, the raduis of the butterflies is less than allowed for safety. they may have a slight chopping/cutting effect on pedestrians

you can have it out through the bonnet as long as it meets the height requirement but the rule is no moving part outside the bonnet, filter is ok ,carby no .butterfly is actuated via a linkage so no.but if you remove the butterflies and use it as a scoop only this is fine.

KrisMobbs

so which one is right ?? if i remove the butterflies is it ok to have out of the bonnet or will it still need to be covered ??

*copy/paste*

Bonnet scoops/projections may be fitted to a 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 11m 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/projection 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.
• Air cleaners and/or carburettors must be covered by
the bonnet scoop.

As for your tyre/wheel size, in NSW the front must be within 75% x width of the rears and vice versa.

KrisMobbs

so a 15x8.5 with 275's and 15x4.5 with 160's is illegal oh well

mac151

Yeah mate. I reckon you'd be pushing the friendship a bit.

AGGRO

i think its 60% here in qld, and u can only go 1.3 times wider than the largest optional tyres for that model, so for Lh toranas the widest was a 195/70/14 on the L34, so 253.5 mm wide i can go to...

KrisMobbs

i have no idea about the HJ premier's
