bhavin85 Posted November 30, 2009 Share Posted November 30, 2009 Hey guys So driving to work this morning...I had to go through a fairly deep puddle...me being me and it being 6 am I didnt even think about my CAI! the water was fairly deep I got through the puddle and noticed that when I put my foot down the car being jerky! anything above 2.5k and the car was rocking backwards and forwards like a crack addict in a rehab clinic! So I pulled up to the side turned the engine off for 10 mins had a quick look around the bottom of the filter and could see water in the undertray...first thing that goes through my mind...thank god I put the hydro lock foam mesh thingy in my Nismo CAI! Started the zed after a few mins and it didnt tick over straight away but after a few attempts it fired up...rev'd past 3k and it seem'd fine! Question is what (if anything) can I check to make sure ive not really destroyed the engine? The car was fine for the rest of my journey...took it to 4k after drivign for about 40 mins and it seem'd fine but just want some piece of mind that ive not jsut broken my zed! I am thinking of making the CAI back into a SRI for the rest of winter as I do drive through some country lanes that can flood! advice would be appreciated Quote Link to comment Share on other sites More sharing options...
Ekona Posted November 30, 2009 Share Posted November 30, 2009 If it's fine now then you got lucky and I wouldn't worry any more about it. Personally I'd never have an intake that low to the ground as for the sake of maybe 1bhp (if you're lucky) is it really worth the extra aggro and worry? Different if you live somewhere baking hot where it never rains though, I guess. Quote Link to comment Share on other sites More sharing options...
BladesGrant Posted November 30, 2009 Share Posted November 30, 2009 Slight thread hi-jack so apologies but a question regarding the thread. As I am running a K&N typhoon the air filter is still in the same place as the original but there is a scoop that goes behind the grill. As this isn't a sealed scoop I am presuming that although you may get some water in the scoop it wouldn't suck loads of water into the engine. The scoop isn't sealed onto the air filter either. I am not planning on taking my car through a deep pool anytime soon to test this theory just a thought in my head!! Quote Link to comment Share on other sites More sharing options...
yokomo Posted November 30, 2009 Share Posted November 30, 2009 slightest air gap and the weight of water vs air means it wont suck the water up if you had sucked in enough water to get in to the engine afaik 2 things can happen .. tiny amount goes in ,engine burns it up (vaporises it), basically you got lucky you suck in so much it gets hydrolocked and your forked !

Mark@Abbey m/s Posted November 30, 2009 Share Posted November 30, 2009 Might not be the induction system , we have found the crank trigger sensor which is at the bottom of the gearbox, gets wet and upsets the crank trigger output.run the car for a while and it should sort itself out , will need the car turning off and restarting thou to reset the ECU. anymore questions fire away.

Chris`I Posted November 30, 2009 Share Posted November 30, 2009 Sounds like you had a close call! Thats why I'm liking the new Stillen Gen 3 design for the 370z. Keeps it nicely tucked up high in the bumper but out of the engine bay. Quote Link to comment Share on other sites More sharing options...
geoff-r Posted November 30, 2009 Share Posted November 30, 2009 Sounds like you were lucky. Those that have the intakes in their engine bay will be fine, the filter needs to be submerged to suck into the engine, and then you really are stuck!

GT4 Zed Posted November 30, 2009 Share Posted November 30, 2009 Lucky chappy . This could have been worse if you had the coilovers on Quote Link to comment Share on other sites More sharing options...
bhavin85 Posted November 30, 2009 Author Share Posted November 30, 2009 With the coilovers i would have been screwed i recon The car seems to be running fine now though so I guess i did get away with it! I am gonig to switch to a short ram intake setup till the end of winter then back to the CAI for summer...dont fancy taking that risk again! Thanks for the help guys!

I am not planning on taking my car through a deep pool anytime soon to test this theory just a thought in my head!! Yeah - i have the same setup. Air scoop goes into the front middle of the bumper (so pretty high up). The filer itself is housed in a black metal case, but this isnt air-tight. So are we correct in assuming that the chance of hydrolock on this setup (if we stay away from 2 foot deep puddles!) is pretty slim? Quote Link to comment Share on other sites More sharing options...

givememorepower Posted December 1, 2009 Share Posted December 1, 2009 Surely if you have the air intake cut out of your front bumper in front of your cone filter and you are driving into heavy rain at approx70mph, your filter would get soaked?? Granted the air flow would hopefully dry this out, but would this affect the engine at all? Quote Link to comment Share on other sites More sharing options...
yokomo Posted December 1, 2009 Share Posted December 1, 2009 if you have it ducted directly in then posibly , maybe this is why nissan didnt put i there to start with ? the stock air box looks soooooooo designed to have that scoop yet does'nt . best for peeps wiht the duct to go from here !
