i'm interested to know what science your basing your facts on here. we are talking about the same carbon fibre that is flexible enough to be used for snow boards and kite surfing. or resiliant enough to temperature to be used for exhausts on motorbikes and cars. the same material that has a tensile strength 3 times of steel, yet a density 4.5 times less. the fibres are made at temperatures over 3000 degrees celsius and also have a boiling point of over this as well. can't remember the melting point of it, and am struggling to find it. but i'm fairly certain that its about the same as aluminium.
its an inert material which is extrememly flame and heat resistant, and is a proven material in F1 from gear boxes to chassis, bike cogs, etc etc.
i agree that yes we have to becafeful with our supplies, and your right to point out BM's thread as it brought to light many importnat areas on this forum when it comes to supply. but scott has already been producing parts for people and i have seen and can vouch for the quality of those items.
i also agree that for the 350z this is an untested area, but i am more confident in the product due to the company already making similiar items for other vehicles.
i would say it possibly needs a running in period on scotts car to prove its abilities, but i am fairly confident that it won't melt into the intake valves.
and if the engine bay temperqtures are getting hotter than the melting point for aluminium we may need to inform nissan to tell them not to use that for their current plenums.
