CF Bonnet or Engine damper??

[DC5TYPER]

Skip both do suspension. I've got a CF Vented Bonnet. Great for track day to keep the temp down and in summer. Looks tough too but not as important as suspension, especially in a older gen cars.

[JasonGilholme]

Its illegal in NSW at the very least. Reason is the CF bonnet is made from a material that is so much stronger than aluminium or steel that it will not bend in a crash and defeats the purpose of the car's designed crumple zones, removing safety. It may shatter and reduce resistance to an impact increasing the forces in the crash or it may hold in one piece which could be worse - it could then come straight through the firewall or windscreen and decapitate the driver. Its also flammable.

That said, my trouble and strife works for SP Systems - they make highly advanced composites for racing yachts (1st and 2nd in Sydney to Hobart, 1st and 2nd in Australian 18' skiffs, and 1st in worlds 18' skiffs), aircraft, and pleasure boats. They did a test composite bonnet for a Porsche that competed in Targa Tasmania last year, and subsequent to that have been in negotiations with HSV about doing composite boot lids.

I wouldn't go down the CF bonnet route for a road registered vehicle in NSW. Just get the full bonnet CF lookalike stickers or paint it black like every other ricer does and put the money into suspension mods for improved performance.

Thats bullsh!t.

Why do you think they started making F1 cars out of Carbon fibre instead of alluminium. Its stronger, lighter and when its pushed to its breaking point it has better crumpling properties then aluminium.

I cushions your impact better then anything else i've seen.

If it passess on the track under such tight safety regulations it should be able to be passed for our roads.

Are CF Bonnets legal in QLD??

You're clearly a dickhead. Evidence above.

The track use of carbon fibre in F1's is purely for aerodynamics, the cockpit is made of an aluminium reinforced spaceframe and is the structural component of the car. The panels all disintegrate and fly off on impact in F1 crashes but the cockpit stays in one piece. As for track use justifying road use that's just ignorant. The track has run off areas with sand/gravel traps, solid concrete walls lining it with no trees, on-coming traffic or power poles to contend with. Nothing like the street from a safety perspective.

Pull your head out of your arse JasonGilholme.

THey use it coz its light, as well as strong. Its also not metallic and doesnt cause sparks if it scrapes along the road (which can lead to explosions). Also, F1 cars are not designed to have crumple zones like regular cars. There are plenty of racing approved mods out there which are illegal.

That being said, i think i heard that you CAN find bonnets which are DOT approved. I think if you get an engineers certificate for it its ok. But with all this money being thrown around you're better off putting it into something else.

what is a Porsche GT made out of KWICKS?

Gee mate sorry for incorrectly re-iterating something i heard on the discovery channel 3 years ago!!!

Im not a dick head. Was just saying what i've heard.

[bennjamin]

Was just saying what i've heard.

THIS is the 1st most common casue of CRAP in forums the world over.
Saying vaugley what you heard here and there - the peopel YOU heard THAT off ALSO heard the same "vauge" info too. So , how can your info be correct at all ?

As Tinkerbell said , DO NOT SPREAD FALSE INFORMATION OR INFO YOU JUST CANNOT BACKUP ! Use our forum and DONT misguide people ok ! If you dont 100% know , either link it or shut up



BACK on topic.
As i initially said , and Tinkerbell expanded on - a CF hood is a decent amount lighter than stock , reducing the weight above the front end significantly increases steering response.
Off the top of my head it is because weight at the top of a objects mass is more influencial in movement than say middle or lower sections.

So isn't the discovery channel a reliable source now.

JUST TO POINT OUT.

If you are hitting a pedestrian in a road accident hard enough to bend metal, they're dead anyway.

[STTICH]

both are BLING items - in other word , do hardly anything and just look good

Id spend $$$ of a CF hood as its a decent amount of weight off your front ~ if u have newish engine mounts whats the point in a damper ? Just get a new aftermarket rear engine mount.

so much confidence.

hav u tried the damper before? ie: comparing changing engine mount Vs adding engine damper.

its a generalised statement mate Aimed at you , and all others in this thread to calm down
BTW ~ since when does an american show have any influence on ADR's represented in this country ? IMO (no , not that i "heard it") Im sure more than anything , CF is "illegal" because it dosent meet ADR requirements.

so much confidence.

its IMO ~ not what ive heard. The items for sale to the usual consumer hardly are worth it. People change engine mounts etc to harder materials 10 times more commonly than this engine damper. Apart from cost. they know it would probably last alot longer than a small boot strut holding the engine.
IMO
