When you get into a crash, the carbon can shatter and do more damage if u hit someone.
I think there are a couple carbon fibre bonnets that are ADR'd which might involve them being laminated so when an object hits them they don't fragment into little ninja stars
cf gets nasty. when have a head-on it splinters into little javelins travelling a squillion k's an hour in every direction. bad.

Not sure where you guys are getting your information from, but carbon fibre is not a mythical fabric weave that all of sudden destroys anything in its path when it breaks. The actual carbon fibre itself does not do any damage, its more often the clear coat on top that has stuck to the carbon which will cause minor splintoring. Depending on the construction type (I'm assuming wet lay-up which most carbon items like hoods and bootlids are made from) will have the same properties as fibreglass when it's crushed or hit with force. You also need to consider that almost all hoods on today's market are not really made entirely of carbon fibre. They are a fibreglass skeleton with only a single layer of carbon on the top. You should also remember that all of the top motorsport categories like F1 and high end sports cars use carbon fibre (or a carbon/kevlar mix) to construct their chassis.

and this means....... it still shatters and stabs you like a gazillion javlins lol..... and that they are still defectable???? also don't trust that something is ADR approved, trust me when i say there are heaps of fake ADR shit going around..... especially in bike and race car helmets..... also i have never come across an adr aproved carbon bonnet either..... has anyone actually seen one that is legit????

No it doesn't shatter and turn into little tiny javelins. Having broken carbon items myself I can tell you that this really is a myth.

Also helmets come under the Australian Standard (AS/NZS1698) not ADR.

this shattering flying shards thing is not really accurate. the main problem with most carbon bonnets not meeting ADRs is to do with pedestrian safety. normal bonnets are designed to absorb the impact of a pedestrian you hit. carbon or fibreglass bonnets wont behave in the same way under those conditions. yes another small danger is it can brake at the mounts and end up like a flying disk, or it can break into sharp pieces but the big one is the pedestrian safety.

I think Blits bodykits in QLD make ADR approved ones.

does anyone know where to get a plain carbon bonnet???? one with minimal vents in it??? for an r33 all i seem to find are stupid ones with massive air vents in them that look like they'd drown my coils in water if i left the car in the rain for a day.....

      RB25DE NEO with Haltech ECU

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
