I am just wondering what risks there are with cold air intakes, particualarly the AEM one. I realize that in theory the bypass valve should solve the potential problem of hydro-locking your engine, but I've heard of problems with the bypass valve itself. What do you think the chances are of hydro-locking your engine assuming that you try to stay away from large puddles etc?? THANKS!

 

id say o well just get it i did

 

I think the most recent one 'ahhh rain' is about bending the valves, but pistons and lots of water was mentioned in the post. that's just my take - reading only half the story as it was presented on that thread.

if you look at the CAI's they have a long way to go up there, and you need to get in some deep water or enough water to stop up the engine, before it stalls or create enough vacuum so it pulls that water up the tube. its not impossible, but it certainly seems difficult and a rare occassion.

the comptech cai has a box before it hits a filter and the inlet isn't as low as the AEM/Injen cai's - so a bit more of a safety procaution w/that one IMO.

summary - the issues are slim, but even in a low car like this.. watch out for highwater regardless.

 

Thanks for the contribution, Tiger. Next time, you might want to post in English, though, because that's the language most of us speak here on s2ki.

As for the CAI.. I have one on my Prelude, and my roommate has the Injen CAI on his S2000. I personally know quite a few people with AEM/Injen-style CAIs, most of which who run without the bypass valve. Assuming you don't try to ford any rivers, I think you'll be okay. If/when I finally get an S2000, I intend to purchase the Injen CAI as soon as possible.

As Matt mentioned, I have the Injen on my S2k, and have driven through LITERALLY 6 inches of standing water (right after driving through some hail ), and I had no problems.

I was scared as hell that I'd get hydrolock, but it was fine.

If you read the post again, it sounded like the guy crawled over the puddle. Big mistake! If you simply fly over it, the plash shouldn't be as bad as slowly dipping it and giving it both time and quantity of water to flood your filter. If you do a fly by the front bumper will shield the filter by diverting all the water to the side, top and under the car.

I'm not an expert on aerodynamic but my understanding is that if the flow of air is not smooth within the confinement of the tube it will create wind turbulence thus reducing the speed and increase the temperature of the air. A free flow pipe will always give you better result. The valve will restrict some % of the air flow.

As I've said in previous posts, if you see the puddle and think it's going to be deep, speed up, say 20-25 mph, then push in the clutch just before you hit the puddle. You'll slow WAY down if the puddle is deep enough, but won't be going fast enough to do body damage, and the engine will be at low RPMs, just in case.

 

If you can show me how you can drive an S2000 with 14,000 miles on stock S02's through 6 inches of standing water at an intersection quickly, I would love to learn. Mind you, this WAS NOT a puddle. It was a good 75-100ft of standing water. And I have the Neuspeed springs, so the bottom of the car is about 1.5" off the ground, and the filter sits only slightly more than that. I know for a fact there had to be water covering at least half of the filter.

Plus, Speed wouldn't matter since my front brake duct is cut out.
