I am tempted to give it a try as i like the design and the fact that the intake is nice and low to the ground so that the air is coming right in from the outside. my only concern is clearance on a lowered vehicle as going through any kinda of significant puddle will cause problems with water in the intake. course you could always get the AEM bypass valve and that would take care of the problem. the only issue with that is you would have to cut a small section of the intake out for the valve to fit in front of the MAFS. The other reason i am hesitant is that i am installing the SC and am not sure if this CAI would be compatible. the one that comes with the SC has the dinan style but does not go as low as this one. hmmmm oh well guess i will just have to ponder on it. LOL

if you get one then let us know how it works and dyno it so we have some results to look at.

Yup
Im gonna be ordering this week as soon as my new visa comes in. Looks good at this point. I might be doing a dyno on the 26th at edge motors.

So ill prolly take it off for the first round and then put the CAI back on for the other 2 rounds.

As far as dyno is concerned the gains will most likly be the same as say dinan.Its a pretty basic concept.

Its just different from JC per say you know? cuz that pipes like 6 inches long where as this ones 12 inches with a 3 1/2 inch width.

There are alot of people that get cosmoracing CAI and some that get the cosmosracing CAI. These are different companies and with 2 companies having that similar of a name it throws flags for me. I don't trust either although alot of people have them and like them. I will spend the extra for my conforti or dinan intake(just like I bought a real performance chip and not an ebay one). They are supposed to do the same thing, but the money is worth my peace of mind.

Edit: By the way the cosmoracing.com site looks like the reputable site and cosmosracing.com looks real sketch.

[snapback]312186[/snapback]
Well the cooler the air the better for detonation. a CAI will aid in the cooling process. The air going into the FMIC (Front Mount InterCooler) is going to be cooled by the air flowing through the FMIC and then put into the SC for forced induction. If the air is cooler than normal once it hits the FMIC then it will be further cooled before hitting the SC. My 3000GT had not only twin turbos but also an SC. The air flow went like this. Air in through the CAI into the two turbos. then spooled into the FMIC which then ran into the SC. Now the SC had a built in Air to water core which further cooled the air before the SC dumped it into the manifold. by putting cooler solution into the Air to water core than the normal coolant i could lower the air going into the manilfold to that below ambient temperature outside the car. So you see a CAI will aid in any situation NA (normal aspiration or non-forced induction) or forced induction.

ok show me a diagram on how this twin turbo SC setup went and where you put the CAIs, i dont understand why you would need a CAI with an intercooler since the intercooler will cool the air plenty

ok this is gonna get technical so if you need more info you will prolly have to do some more research. First of all, on this 3000GT the CAI is located down in the front valance below the lights on the passenger side. the air travels up the CAI into the two turbos through a split tube. the turbos spool the air and then send it down into the FMIC which gets cooled from the outside air. the air then travels into the SC where the air goes through the ATWC (air to water core) getting cooled some more then into the manifold. Diagram wise if you need one i can draw you one. LOL ok now for the technical stuff. here is how the cooling works and why you want all the cooling extras as the FMIC will not do the job completely.

THE EATON SC AT 8 PSI WILL ONLY PRODUCE A 70-80 DEGREE DELTA RISE. THE W-T-A IC WILL HAVE AN AMBIENT TEMP MINUS THE WIND-CHILL FACTOR WHILE MOVING. THAT DROPS THE THEORETICAL WATER TEMPS TO 20 BELOW DELTA. IF A 75% EFFICIENCY IC IS USED, THEN 80- 75% OF (100-75 DEGREES) IS A WASH +/- 5 DEGREES. THE SC WILL DO NOTHING AT ALL ONCE THE TURBOS MAKE BOOST, SO THE DELTA RISE WILL BE 0--THATS RIGHT--0, AND ADDING WIND CHILL FACTOR WOULD GIVE A DELTA - 15 DEGREES.
THE TURBOS PRODUCING 17 PSI WILL RAISE TEMPS 175 DEGREES @ 75% A.E., AND THE A-T-A INTERCOOLER (FMIC) AT 65% WILL DROP THAT BY 113 DEGREES. SO NOW YOU WILL HAVE DELTA + 61 DEGREES AT 17 PSI +/- 5 DEGREES. IF YOU ARE MOVING THE A-T-A WILL HAVE THE WIND CHILL FACTOR DROP THE TEMPS ANOTHER 20 DEGREES OR SO, AND THAT MEANS ABOUT DELTA + 40 DEGREES @ 17 PSI. ADD A WATER/ALCOHOL-COOLER SQUIRTER WHICH COULD EASILY DROP 50 DEGREES FROM THAT. NOW THE AIR ENTERING THE ENGINE IS COLDER THAN OUTSIDE AIR.
WITH BOTH AN A-T-A AND AN A-T-W IC. THE A-T-A IS FIRST DROPPING 30 PSI BOOST FROM DELTA + 285 TO DELTA + 100 DEGREES. THE 40 DEGREE ICE-WATER IN THE A-T-W WILL DROP THAT +100 ANOTHER 75%, SO DELTA - 40 AS THE MEDIUM WILL GIVE:
DELTA (85 DEGREES) + 100 =185 DEGREES. 185 + 40 DEGREES (225) X 75% = 169 DEGREES. 185 DEGREES MINUS 169 THAT MEANS DELTA -16 DEGREES AT 30 PSI BOOST(69 DEGREES)

So there you have it. All you could possibly want to know about a twin turbo SC 3000GT and how important cooling is based on temp outside and inside the engine compartment. Again sorry for all the technical stuff but it helps explain.

i understand why you want cold air and how a turbo works, and i also know that unless for some reason you dont have an intercooler before your turbos a CAI would really do no good, yes you have to have some kind of air box with a filter, but if your 3000gt came stock with the forced induction then they prolly used the factory airbox which, with an intercooler, would do just as much good as a cold air, cause the intercooler cools the air just fine.

if you have a link to where i can see exactly how that system is set up then post it, i would like to see it anyways cause thats a pretty sick setup
