I'm goin with a cold air and am wondering, what is the likelyhood that my engine will go into hydro-lock if i don't put on a bypass?
Ah.......the old bypass quesion...

I don't think that's entirely true.. Because having that spot open at all times, is going to lower the velocity at which the air travels up through the pipe....i rekon

I have actually been thinkin about going with a short ram and then getting a vstack with like a massive K&N filter. It seems like a safer alterative but provides the same power. what do you guys think?

o and is it possible to just get the piping for the AEM short ram cuz i'm gettin the K&N filter separate and i dont need the $50 filter that comes with the AEM SRI.

I guarantee you, it is nothing you will notice on a dyno.

If you have a lowered car, the chances of hydrolock with a CAI is a bit higher.

The bypass valve does NOT rob any hp.

Once the tip of the CAI goes under water it simple suck air through the foam sides of the valve.
thats exactly my point. when there is a 'hole' in the side of your 'straw' you are sucking warm engine bay air into your engine, not cold air from the wheel well. so my point still stands, you basically have a $275 SRI

You are only sucking warm air ONCE THE TIP GOES UNDER WATER. Once you drive out of the puddle the CAI works as normal. No more sucking through the side. Now if you plan on driving in 6" or more of water for a long period of time, then yes you are correct.

I have dyno'ed with and without the bypass. It did NOT make any difference.
However, I was not under water when I did it so I get your point.

how exactly does a 50 dollar bypass valve know when theyres water in the pipe? i dont understand how it would be open if the filter was submerged and closed otherwise.
