While i was at the workshop i was talking the the guys there and they showed me there fiberglass bonnets that they make. I was looking at molding the scoop to the bonnet and asking them how i go about it ? They said to me that if there was enough deman for them they would be happy to make up a mould. Now i thought what better place to find this out but on this forum? I dont know how it goes with rego and stuff but they make alot of holden bonnets for VT,VY,VX An up side they were telling me is that the weight from a standed bonnet goes from 22kg down to 7-8kg which i know for the drag guys every bit counts?
So just wont to see what people think about this cause i am more than happy to donate my bonnet for the mould

Alfa Fibreglass for example, want $540 for a 'street' bonnet and their products are among the best.

In WA under the NCOP metal bonnets and guards can only be replaced with fibreglass or other composite panels on pre 1971 (ADR 10) vehicles. I suspect it will be the same in most states.

Front structure
Where ADR 10B, 10/00 or 10/01 applies, the front of the vehicle is sometimes designed to crush on impact to
absorb crash forces. Any structural modifications in this area should only be made on the advice of an engineering
signatory experienced in body and chassis structures.

An Approval Certificate is also required for modification to the occupant compartment and panels forward of the firewall of any passenger car manufactured after 1972.

In QLD it's a big NO! to fibreglass panels I believe. I tried a couple of times to make a steel bonnet scoop and failed miserably both times. I'll have another crack at it though. Have a look at the superformance site and click the 'new products' button, they have reverse facing steel scoops for sale. Just weld it on, smooth it up and you're home n hosed
any chance of a link?
i'm a lazy old man lol

Sorry mate, I don't know how to make links from my iPhone. Just google 'superformance'. I saw an ad for them in Just Parts magazine so I checked it out online. They look good

I do not know how you would prove that they do not affect the crush zones that were designed into the metal bonnet and guards to meet ADR 10.
The bonnet skin is not structural and is not attached to the frame in any spectacular fashion. It is just designed to peel back. The frame is the ADR compliant bit, which is why you need it rebraced and certified if you cut into the bonnet, to ensure the bracing has not been compromised.
Hence you will see alot of scoops with the centre bracing running across the hole (where they don't need the clearance for high carbs...)
As said, glass bonnets and guards cannot be used legally on the street in QLD. Unless you connected a glass bonnet to the existing frame, then no hope - and then, the frame is where most of the weight is......

I don't like the look of that rib that runs down the centre of the bonnet scoop. It also seems to be too far in front or too long, it just may be an illusion from the angle.
Do they have ones that look like orig. A9X scoops?

1. It has to be strong enough to support a person if you run over them and they land on the bonnet. Hence the requirement for some states to need a metal A9X scoop if it's not original and the underside bracing may need to be retained.
2. It has to fold up in an accident to avoid it slicing through the windscreen incase the mounts rip out.
That's why bonnets have the groove-(2.)

An engineer may be able to comply a bonnet?

Cheers, so where it joins the bonnet is it seamless as in a one piece with the bonnet?
