Hhahahaha, stone cold intake at 100mph.. seriously dude??
it is attached to the cylinder head, are you telling me that your engine is sooo efficient that 1100f+ does not radiate anything greater than ambient temp 2" away??
I don't know about your engine but mine doesn't radiate 1100F from the head. 
.....the 1100F stuff goes out the exhaust pipe. Ever think about what the coolant does? I think it maintains a coolant temp of 180-195 degrees and so I don't think it's possible for the head to radiate anything hotter than that.
Some have "let" the coolant drain out and I'm sure radiated more than it should have.....
I don't have a turbo but IIRC I can touch my intake manifold after a good cruise and not get burned until it's sat and heat soaked for a bit, kinda tells me there isn't much heat getting to it from the head while driving.
did you guys forget that whenever the engine is running, there is AIR FLOWING THRU the ports.. and that is actually cooling the manifold also, believe it or not!
yes, swear on my left teste.. 100 mph run, pull over, engine still running, pop hood, touch intake.. oh yea, nice n cool..

with an intercooler the turbo can move the same amount of air with much less effort, the turbo doesn't become more efficient, but because of the cooler there is less pressure for the turbo to fight (which means your exhaust side will have to do less work). the flow of fluids is a really tough thing to understand sometimes, i work with everyday, i work on pft machines, ventilators, and a bunch of other medical crap. temperature and atmospheric pressures effect everything a lot.
I can understand your logic. The pressure drop is at the IC though, so in the charge pipe coming off the turbo, wouldn't the PSI still be reading 18psi and therefore not making the turbo's job any easier?

goes about 115 mph on the top of 4th gear with a GC trans..
do the math.. its possible.
if you dont believe me, ill race your diesel rabbit for pinks, since mine wont go 100 mph
(~20 psi boost @ 100 mph)

my car went 100 mph when it was n/a.. so why would it go slower with a turbo?
are you soo dense that you actually believe that a VNTD rabbit wont go 100 mph?

Lets try and limit the personal attacks and focus on the topic of this thread please.

Lets try and limit the personal attacks and focus on the topic of this thread please.
ive stated multiple times, in multiple threads that my car goes over 100 mph. and has gone over 100 since ive owned it..
i mean, hell, i got it up to 90 mph the first day i owned it.. only things i had done to the engine were check the water and oill, and replace a missing air filter clip..
i will say it again.. my intercooler keeps my intake cool even directly after a 100+ mph run..
if you guys dont believe me, then good for you. it will be more of a surprise if any of you actually get to see/race the car..
another thing i bet you wont believe:
my car keeps up with a stock SRT4 until the srt hits 5th gear. (im crippled from my 4 speed)

i believe they can go 100mph, i've done it as well, i was only joking
to tyler, air flows from an area of high pressure to an area of lower pressure, the larger the differential the more flow.

and more flow equals higher velocity and therefore lower psi?
I almost wish I had a turbo and 2 boost gauges to test this out... Or even my textbooks on hydraulics would suffice

i am thinking it has less to do with velocity, and more to do with the pressure differential across the intercooler creates a more flow that the turbo charger does not have to make up for, so that is less work the turbo has to do to move the same amount of air, so that is less energy u need from the exhaust side of the turbo and more energy going into the crank shaft. im sure velocity is still a part of the equation tho

I appreciate all the input but about the whole air to water/air to air debate anyone have any more input?

i believe you could make an A2A fit easier than an a2w..

I love my A2W setup. It fit well, it works great, not really much more I can say than that. I am running at about 15 PSI right now till my EGT gauge goes in, and after a highway run the post-IC intake piping is cool while the pre-IC piping is too hot to touch. I have maybe 3 feet of piping and only about 5 couplers so a lot fewer places to have problems in terms of boost pipes coming apart. I had absolutely no difference in spool up time and only a very slight decrease in my maximum boost (less than 0.5 PSI).
For me the 1" thick radiator for the AWIC was what did it. You'd never get an A2A IC that flowed anything decent that was that thin.

Interesting! I'm leaning more toward the A-W direction. I just don't see it working as smoothly with an A-A due to space restraints.
What site did you get it from? Could i talk you into posting some pictures?
