cold air intake vs short ram

Wait... What?
i think what he meant was that the car will not suck up water unless the filter is nearly submerged... it would take alot of suction to suck any amount of water through a filter...

just get a sri ... the worries arent worth the 1 extra hp ... besides its easier to change the filter

Say you have a 2.0-liter engine (just because it makes for simple math). Each cylinder measures 500cc. If one cylinder sucks up 100cc of water then you're in trouble. If the engine has 10.0:1 compression ratio (GSR C/R and easy math purposes), then combustion chamber would be reduced to 55.5cc at TDC. So a piston going up with 100cc of water in it is on it's way to self destruction. Water does NOT compress. When the piston reduces the combustion chamber to 100cc, the piston WILL stop. And if you are lucky, you're engine will too. If it doesn't then blown headgasket, broken ring lands, broken rod or any combination is likely.
Isn't this taken STRAIGHT from the SCC article testing AEM's bypass valve on an NSX?:lol:

No but I think they did do a test on it a long time ago. It's just math, it works the same for everyone lol

Haha I know its just funny because the wording is almost exactly the same lol.
It probably seeped into my brain from a long time ago. lol I do remember reading that article like 4 years ago. I don't remember what numbers they used but it was probably damn near the same. 2.0L and 10:1 just make for simple math and an easy example.

Honestly, Stock airbox with K&N filter, with or without resonator. I really didnt notice any change from sri to the stock setup, with my cai i noticed more power but it rains a ton here and isnt worth the trouble

Stock airbox with a new filter is a good choice, if you want the sound remove the resonator (big white box thing thats a bitch to remove) OR get a K&N intake w/ heat shield so your sri sucks up less hot air

yeah if your an are wher it rains scratch the CAI, best bet to get benefit of cool air would be a SRI with heatshield.

You guys are way too paranoid about CAI's sucking up water. I had one for 3 years, I'm in N.H., it rains and snows plenty, I never had a problem. The filter is behind the wheel well liner, it's pretty well protected in there, you really do need to basically submerge the front end of your car in a lake to get the intake to suck up water....water that'll actually reach the TB. Don't worry about it so much.

We just have to accept that people will always fear the dreaded hydrolock...
