A 15X7 3" Front Mount intercooler was installed over the weekend by http://www.chargedair.com. Air intake temperature before FMIC under boost was 133 degrees(F).
After the intercooler, the temps were 60 degrees(F) under boost with the outside air temperature at 40 degrees(F) in both before and after tests. It appears that I lost about a half a pound of boost but with the 73 degree drop in air temperature the overall mass with be greatly improved with the increased density. Just remember it's not the quantity of air you want it's the quality!!!!!! Next stop the dyno with an air fuel meter.

It costed me $1100 installed...
It ended up taking him about twice as long as he had anticipated to do the install. I asked him about pricing for future customers and he stated about $1500.00 to $1600.00.
I'll post some pics on my homepage sometime this week.

thanks for letting me know. sounds a little high depending on the dyno. if it shows notable gains, we will do it. how much modification of the car needs to be done to get it to work. also where is it located? is it in the scoop of the mouth of the car(at the bottom of the front so it is exposed to frontal air) or is it just mounted in the engine bay. i saw someone with an intercooler in the engine bay. couldnt understand how it could cool anything. who should i ask for when i call that place?

The dyno wont do it justice
as the air wont be blowing at the intercooler like at the track. It's located in the scoop of the mouth of the car(at the bottom of the front so it is exposed to frontal air). It's a front mount.
Ask for Tony(the owner). He estimates 30 hp at the wheels.
The track will be the true test. If it stays dry this week a track might be open but I'll probably have to wait until next year to run it.

The black tube from stillen that goes across the
engine bay is removed. His tubing takes over from there to the MAF. Their is really no modification to the car. The trans cooler and steering cooler got relocated.

Good luck! Im curious to see how it works out!

It's a tube/fin core with nockolok brazing. An extruded tube/fin core is the most effective core matrix available.
It's a tube-fin core. Bar-plate is old school.

Yep, it's normal for boost to go down when you cool the intake air. Temp/pressure are related, remember, so if you drop temperature, pressure falls accordingly. That DOESN'T mean that FLOW is reduced, though; conversely, flow will go up due to the increased density of the air.
Remember, the SC is still spinning at the same speed with or without the intercooler. If the post-SC pressure has actually dropped, then there's less resistance to the air exiting the SC, hence the flow through the SC will actually increase.
Too many people get caught up with the notion that more boost is better. Not the case. You realize that all I'd need to do is install a small orifice reducer somewhere downstream of your pressure transducer and I could "boost" pressure 5/10/15 psi. All the while flow from the SC decreases. "Boost" pressure is as much an indicator of improperly sized flow paths as it is big/bad compressor.

As far as HP increase goes, 30 HP gain is far optimistic. Think things out logically: every 10 deg intake temp drop equates to roughly a 1% density increase, hence a 1% HP increase. For a 72 deg drop, that 7% HP increase. For a 250 HP (at the wheels) engine, that's a ~18 HP increase, NOT including the power drop due to the flow restriction of the intercooler core. If you account for that significant restriction, which I'll guess is 40% of your cooling gainm that's a net HP increase of ~10-12 HP at the wheels.
The REAL benefit of the IC is that it allows you to reduce the pulley size on the SC to crank the boost back up. You can go above the original boost pressures now with the IC. Now the combination of the smaller, higher-boost SC pulley and the IC may give you 30+ HP at the wheels, but not the IC alone. At least on the Maxima.

Nope, I really don't post, but then again why would I? No interesting upgrades or discussions, and I can't afford a new Altima or Maxima so why would I want to read about how much better those cars are than mine...boo hoo poor me. Although it's nice to see that some things never change...such as people buying a new car every 6-12 months, trying desperately to get attention on this forum, etc. 
I've been drawn into the forum recently by the revelation of subframe connectors. Dammit, I might have to buy another mod.
