I mean I guess that is my personal preference if I ever ran a cold air intake. Then again, I don't ever seeing myself going with anything outside of a DD that is non-turbo.

Unless youre saying he hit a pothole that caused him to submerge his intake, and if thats the case- he hit a LAKE, not a pothole.

Also, im not sure what you meant by "pistons were rounded out," but in the case of hydrolocking, usually the piston will completely blow apart. I sucked up water in an ATV a few years ago, and the piston was undamaged, except for a hole the size of a quarter in the top of it.

Thanks for the new sig, alex.

x2 lol....thats funny. in my experience the pistons usually hold up but rods are a little less then straight and true

I guess I need to be more clear. It was a pothole while he was driving in the rain and it was filled with water (unless you didn't figure that out as well). He was driving on Rt. 208 when it was raining towards his workplace near Garden State Mall. I am not sure but how exactly do you "avoid" a big pothole while driving on a highway in heavy rain?

I guess I should have also specified that the pistons got rounded out because of the rods getting bent out of shape and were smacking the piston against the valves.

[420sx]

That too. I guess it depends on the engine, but i have definitely seen some mangled rods due to hydrolock now that you mention it. The only time Ive personally experienced it is by blowing a hole in the piston. Like 10 hours after rebuilding the motor too. Man I was pissed lol.

Oh, so he hydrolocked it, bent the rods, and it still ran? And he continued to drive it? I guess by that point, the pistons were the least of his worries, the rest of the motor was already fubar'd anyway.

So he hit a pothole on a highway that was deep enough to submerge his filter? If thats the case, his car is either SLAMMED, or he was driving in a monsoon. lol

[RedBowTies88]

i still dont understand how this pothole on a major road was large enough to get enough water in the intake to hydrolock the motor... unless his intake was 2 inches off the ground

i watched a v6 ranger make it about 20 miles with 3 bent rods after my buddy romped it through a huge puddle..man did it sound terrible...right up till it windowed the block

[420sx]

Theres a video on youtube that I found rather impressive- dude blew a hole in the side of the block on his Toyota 22r 4cyl, and the thing continued to run for a WHILE. I think they ended up redlining it til it popped.

[RedBowTies88]

22r's are monsters. i also know of a video of a guy that cracked a cummins b series block on the dyno..made 700+hp then went outside and did burnouts for a while till it overheated because all the coolant ran out

Are you sure you live in NJ?

If you go on Rt. 208 towards Garden State Mall from the Nabisco factory, there use to be a massive pothole in front of this gas station. They filled it a year or so ago. Outside of that, I see tons of backed up sewers flooding out small areas of the road.

And it really doesn't require that much water to hydro-lock a motor especially when it is already raining. More and more water simply builds up into the motor. The car wasn't lowered or anything either. From what I gather, he drove it the massive puddle while going to work (guess like 15 miles) and then home (20 miles). Next morning it wouldn't start and after compression testing it and showing 0 psi in 1 and 4, it was over.

22R will last that long (like most older import motors) because they are cast iron. Extremely heavy but doesn't deform/warp like aluminum (unless it is billet mixture alloy), but rather just catastrophically fails at a much higher level. The 22R's head and block were cast iron making them extremely stout. Thats one of the main reason why 2JZGTE and 2JZGE can handle so much power.

water builds up in the motor?...seriously? if there's enough water in the bore to restrict a full stroke its going to lock up, if not its going to be ejected out the exhaust valve or burned up

Here you go.

http://en.wikipedia.org/wiki/Hydrolock

Enjoy sounding like a smart ass.

Gasoline engines
Small amounts of water introduced into a gasoline engine will upset the air/fuel mixture, while larger amounts will cause hydrolock. If sufficient water is available at the air intake, the effect may create a positive feedback cycle, whereby water entering the engine retards the combustion and cools the chamber, preventing the water from being fully vaporized and expelled, which then allows more water to be retained on the next cycle, until hydrolock occurs. Depending on the rate at which water is introduced into the engine, this effect can cut power and speed in an engine to a point that when hydrolock actually occurs it does not cause catastrophic engine damage.

[RedBowTies88]

yes and in the real world the cylinder is going to loose fire WAY before it hydrolocks that way.. if you don't notice you car is running without one or more of its cylinders and don't pull over to inspect your an idiot. like I said i've hydrolocked my fair share of woods beaters i know how it works

As stated in my first post, I wasn't driving, my friend was. I wasn't in the car nor near the car at the time. He just asked me what was wrong after it wouldn't start. I have never owned a car with a cold air intake but I have seen hydro-locking first hand.

I am not saying that water will always build up but there is a chance that it might happen if enough gets in there to start a positive feedback cycle.

[RedBowTies88]

im sure its possible but highly unlikely, i've had vehicles where there was so much moisture in the motor they would barely run and never once has one hydrolocked on me that way. just burn through it with enough compression cycles and you're good to go.


what im really getting at is the OP shouldn't worry about hydrolocking his car with a cold air intake long as he has a brain in his head

Hahaha I knew that too. Ive met him twice- just had a brain fart. Sorry aaron!

It's all good lol, and yeah, it's Aaron. Alex is your buddy I bought the bike off of lol.

i can vouch for this **** actually working. Or there is the old tried and true method, hmm its raining outside let me disconnect the intake from the T/B untill the rain stops. this also works, ask me how i know.

awww him a wittle but hurt?

I'm starting to feel that the OP has to have everyone aprove of what things to get for his car. I was thinking about lug nuts, should I get chrome ones, black ones or yea rainbows. lol
