i stumbles upon a very interesting website, i have ram air and have got scared a couple times. theres a website that sells pressure rated plugs, so if you do happen to hydrolock the spark plug has a release valve so extra compressions goes through the plug and not destroy the engine. anyone try them before? i think ill be ordering some :)

http://www.prepsparkplugs.com/

only thing is i dont know the quality of them, ive heard or people using crap plugs like autolite and losing their whole engine because the electrode fell out and broke exhaust valves ect

i really dont trust those bypass valves for one second.. aem has video clips of it in action but the test are rigged. they put the whole intake under water, of course that will open the bypass because it will create pressure, but what about if half the intake opening goes under water, or water drops splash up into it, a splash of water is not going to activate a air bypass unless it fills the entire diameter of the intake which is almost physically impossible. any more then a table spoon will take down almost any engine, especially cars with timing advance

I'm curious as to where you found the info on a tablespoon is water taking out any engine? This is completly false, being a tech and a person who has hydrolocked many times, I can honestly tell you it takes allot more than that to hydrolock an engine.

Allot more than a Tablespoon, I hydrolocked my G1 Coupe a few months back, when I went through a puddle deep enough to come over the doorsill and into the car when I opened the door, I was completly locked up, no crank.

Pulled all plugs and cranked all water out of cylinders (TONS CAME OUT, guessing at least a few quarts) Put new Plugs in and changed the oil, it survived :) I'm still driving it.

From what I have seen to hydrolock an engine it takes at least 1 quart of water to be directly inhauled into the engine.

Keep in mind Engine size plays a key role here, smaller engines will be more likly to lock up with the same ammount of water than bigger engines due to volume.
