FWIW, the intake on the Supra is 28.27in^2. It makes 320 hp stock at the crank, but mine (and others) have made more than that at the wheels with the OEM intake intact (I even had the OEM filter in place when I put 330 to the wheels with everything except boost stock).
The stock tC intake is 21.73 in^2, for a mere 160 hp. Can you see why I seriously doubt the claims? The tube never even approaches maximum flow. I have no doubt that even with that miserable 90 degree turn, I could get 300 hp out of an engine connected to that tube. It only has to flow 260 cfm at redline to completely fill a cylinder, and they fill one at a time with only small overlaps between cylinders, assuming there's more cam than the 190 degree cam they put in the 4A-GE.
Nextel Cup restrictor plate engines have a grand total of 3.1415926 in^2 (four 1" holes, funny number, eh?) of allowed intake, and they make a whole lot more than 160 hp, they make a lot more than 330 hp. So the size and flow arguments don't stand up to the truth of the flowbench.
But still, I know someone with a CAI, and I'll see if we can make a trip to the racetrack so we can do a true A/B comparison for trapspeed. I'm not gonna hold my breath though, and I'll for sure post my results in this thread.

The only variable will be temperature. The drags start in the evening and it cools off here pretty quickly. That should help the CAI since I'll run stock first, then CAI. Other than that, yes, same car, same fuel, same tires and suspension, etc...

cai for toyotas dont work like that cuz of how their engineered. it takes a few miles for the ecu to adjust to the increase in air flow. so u switchin setups at the track aint gona show u a damn thing. its not a honda. they kick in asap when u change them. i know cuz i still got mine and i had 2 others b4 that. my first was a 90 mustang (can u say YUUUUUK)

Well, since this thread is back from the dead, I'll add that I've run my K&N Typhoon for almost three years in heavy rain, snow, slush, and I even spray down the engine bay at the car wash without incident.
I do try to avoid deep puddles and driving on the left side of the street when it's raining heavily just to play it safe.

Well as some of you Southern CA folks know, its been raining hard here in the San Fernando Valley, I have an Injen cold air intake and this morning i went through a puddle, it didn't look that bad, but there was a dip in it so there was allot more water in there then I taught, the engine spuddered, chocked, then died, I pulled of to the side, let it sit for like a minute or 2, then tried starting it up again, it chocked , but didn't start, tried again gave it some gas and it started, I gave some gas and allot of white smoke came out, drove home for a couple of blocks and drove just fine. So do you guys think something got messed up?

It sounds like to me you had a close call. If you notice anything wrong after driving it then take it to someone. if not just considder your self lucky.
A friends 2jz went through a puddle like that and was hydrolocked. we were able to save it. It didn't run for like 2 weeks. In our case we let it sit for a bit attempting to turn it over like every other day. we also ran some choke cleaner, and sea foam through it and that helped.

Hey guys, I have question for you.
Today, I went to take out my filter to clean. I opened the wheel wall and saw road salt somehow got onto the rubber parts and CAI pipe. I'm kind of worried about the salt getting into the filter and damage it? Anyone ever had this problem? I'm figuring if I got salt in there; I probably got snow in there too and who knows if hydrolocking in a long run?

i have read none of the comments so far but incase noone has said it, YES YES YES YES YES YES YES you can hydrolock with a CAI. I have seen several at the dealership i work at and they all were very expensive fixes. Basically they drove like complete freaking idiots with theres tho. If you dont go hunting for puddles on your CAI side you will be fine

were the cars at the dealership tCs?
though very unlikely... just like you said.. you kinda have to be really ignorant, stupid, or a bad combination of both or whatever to really hydrolock the car
impossible? no.
likely? not really.
