But yes, close enough to make me roll through puddles with the clutch in at idle.

The Z06 has a functional hood scoop. Following too closely to another vehicle in the rain could cause splashup to enter the scoop and cause hydrolock. Even if you go through a 6 inch deep puddle, water could easily roll up over the hood and into the scoop. It could happen and probably will happen to someone eventually. I bet that won't stop people from buying the car. Your car could also get hit by a meteor.

Was going less than 5 mph puddle was less than 3 inchs deep. Front wheels caused a wake that spilled into the bottom feeder. Two rods broke along with two nice holes in block. Motor crackled once and smoke started coming out of hood seal, one frikken sick feeling. I wasn't the only one.
Jim Hall has the right Idea leave it in stock location. The hot air theory is BS and so is the ram air effect.

is this a generalized statement or just one related to the current c6 intake configurations ? i thought a hotter intake charge was less efficient and ram air (if done correctly) can provide that little bit of extra oumph.

Cooler, denser air has long been more able to make more power than warmer air...
I was looking around online and it seems that Corvette people are not the only ones with questions about the sealed boxes, open filters under the hood, and filters grabbing cold air from outside the engine compartment (HOT!)
With a filter on a stick setup in an M3, you'd probably lose power. The BMW engines I know generate a whole heap of heat in the engine bay. Hotter air temperature for air intake means less oxygen means less horsepower. The factory box is supposed to isolate the filter from engine heat while drawing cool air from the front kidney.
You'd get better air flow, but hotter air cancelling the benefit of the other. But you'd get the cool open air intake sound.
I wanted to get an intake for my car and was just going to put on a cone in place of all of the stock filter and tubing.
I was wondering how much hp that extra tube thing from DINAN actually helps vs. just adding a K&N Cone filter.
In the case of Dinan, they locate the filter NOT in the engine bay, but below it, isolated by a metal plate....Once you duct some additional fresh air to it, its not exposed to any of the hot engine air...When youve got to worry is when you just stick a cone to the end of your MAF. Then, all it can do is breathe hot engine air.

Sounds like there is probably still some risk in the Z06 setup.
I don't think any type of "gravity separator" can really eliminate the risk of hydrolock. They only work for small amounts of water.

Also, the Z06 does not have to pass all safety tests that the base Corvette does. I've never seen anyone from GM claim that the Z06 is just as water resistant as the base model when it comes to water injestion. They may run the same tests but there are compromises made in any and every design. There is no way to know whether the Z06 can survive as much water as the base model based on the information we have right now.

I'm not convinced that if you were riding behind a bus and it threw up a nice wall of water on your hood from hitting a puddle, the Z06 wouldn't hydrolock.

Liquid water does not flow the same as air. If it did, the ocean would blow away in the breeze. Liquid water is more dense, has a different viscosity, etc. than does air. Thus, it does not flow the same.

The "type" of flow is the same. Only the resistance (and therefore flow rates, etc) are different.

You can go ahead and believe that everything flows the same. The rest of us know that some things flow one way and others, due to differences in density, state, viscosity, environment, etc, flow differently.
Fluid dynamics are identical, but their flow is not.
