Hi guys.

Have a question for those of you who have or have had cars with vented bonnets. Not necessarily cf vented bonnets just any bonnet that has holes in it.

Sure they look nice when matched correctly to the car and they have better cooling properties. But just wanna know if you have had any issues with water, ie parked when raining or when washing the car.

Ive been contemplating buying a cf bonnet and cant decided on whether or not to go vented. Worried that the water may come in contact with the electrical components in the car and in the more EXTREME (yet possible) case, cracking manifolds. ie cold water on hot steel tubes. Dont laugh cause I know one guy who cracked his manifold from excessive water contact, he didnt have a vented bonnet but I forgot to ask him how it came in contact with so much water.

so any feedback would be nice guys...

:)

In most cases the vents are over the very front of the engine and even on those that have smaller vents on the sides at the rear of the bonnet I dont think water would land on your manifolds.

Some bonnets however that have much larger vents that are situated right over the coils etc may be a different story espepcially if you have your coil cover removed.

In general however I think its fairly safe if you pick the right bonnet for your car

i have a JA starion. for all you who dont know, that was the only model (aust delivered) with the crazy 80's bonnet scoops.

from factory, the ones on the side are totaly for show (ie no venting at all), and the front, although big like wrx's from the outside, on the inside actually no bigger than 2x postbox slit size. seemed hardly worth the effort.

i drilled all the ***cers out...... so

IMHO, goto be better than stock. the more airflow the better!

ive had 2 cars now with CF vented bonnets, R33 and now R34, both fine, no probs at all, as someone else said, the vents are usually positioned in places which wont effect anything, both of mine have had the big vent in the middle between the radiator and engine so the water runs staight out and the side vents have been close to strut towers so neither really allow water to touch anything but the car body, only issue that i noticed was that on the od occasion i would get a little bit of fanbelt squeek due to the water, but it only lasted a second or two....... hope that helps ;):D

My brother has a TRD 3000 style cf bonnet on his Supra and got rain in his pod filter! (he has a pretty huuuuge Trust one) Car didn't like that too much. But the bonnet came with pannels that you could clip under the vents to block them up for such occasions.

"The internet? Is that thing still around?"

      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.
