I just recently bought an r34 and it has a fibreglass vented hood. Seems to leak water into the engine when it rains and the car wouldnt move and kept stalling as the water had got into the intake (i think)

i have an unenclosed pod filter... so maybe thats the issue ?

Im quite sure this isnt a normal thing to happen just because i have a vented hoods! any ideas ? im thinking of somehow blocking the vents to stop water leaking..

- attatched a photo of my engine bay and hood

thanks guyss

i had the same style on my 33, water use to enter through the left hand corner of the main opening, would go into the airbox snorkel straight into the airbox till it filled enough to go into the intake.

I cant see exactly where the snorkel ends on yours but if it is directly above the filter or even against the side that is probably your problem, could also be that the water is getting into the electronics of the afm.

FYI i hope you bought the bonnet for cosmetic reasons, i weighed mine when i changed back to the standard one, the fibreglass one weighed 18.x kg and the standard was 15.x

Removing the snorkel and fitting a cai will probably fix it, unless the 34 bonnet weighs 5x more than the 33 i will guarantee you that there is not that much difference, i dont think real carbon fiber has that much of a weight difference.

The water is getting directly into the engine bay and onto the pod fitler and i think blocking it from breathing properly ? so i dont think the snorkel would work :( and as for the bonnet.. well i can literally hold it with 1 finger and it looks so easy to snap! so im quite sure its light asss

r34 bonnets are heavy as hell

Is there anyway i can just BLOCK the vents on the bonnet?

You could get some sikaflex and thin plastic (ice cream tub should do) and stick the plastic over the holes on the inside of the bonnet, you will have to leave a hole some where tho or you will end up with a swimming pool on your bonnet.

Since it is a non turbo for now just remove the snorkel, i doubt the heat of a non turbo will hurt power, drive it round for a while with out the snorkel if you notice a big difference in power get a CAI if not then you fixed it for free.

I think the position of the middle vent means water goes to the front of the engine its jst the left..

ANd im not sure what you guys mean when you say remove the snorkel ? the water is getting onto the pod DIRECTLY from the vent not through the snorkel!

thanks for the responses!

Well in going of the exact same problem with that exact same styled bonnet on my 33, the water would come in through the corner of the vent run onto the opening of the snorkel that sits on the rad support and then run down the snorkel into my air box, in your case onto your pod filter, instead of arguing with the answers try it, will take you not even a minute to take it off, if it does not work put it back on again.

Looks like you have the very basic water injection kit lol, can only be a good thing just needs a tune with the new setup :P

Jokes aside, is it possible the water is getting in to the coil packs? there is a big thread on vented bonnets and water issues brought up just recently and water getting into coil packs that was usually the main cause for problems.

Would that cause stuttering ? and stalling ? I just assumed it was the air filter because it was wet and when my AFM was broken it would do the same thing.

For now i just put an icecream tub over it and it seems to work :)

Removing the snorkel and fitting a cai will probably fix it, unless the 34 bonnet weighs 5x more than the 33 i will guarantee you that there is not that much difference, i dont think real carbon fiber has that much of a weight difference.

acutally it would be quite a difference;

    • @Haggerty this is your red flag. In MAP based ECU's the Manifold pressure X RPM calculation is how the engine knows it is actually...running/going through ANY load. You are confusing the term 'base map' with your base VE/Fuel table. When most people say 'base map' they mean the stock entire tune shipped with the ECU, hopefully aimed at a specific car/setup to use as a base for beginning to tune your specific car. Haltech has a lot of documentation (or at least they used to, I expect it to be better now). Read it voraciously.
    • I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.
    • @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation. 
    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • 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.
