Well against everything I ever said I would do I broke down and put an "Intake" on my S/C. Basically my goal was to go the entire year w/o modding it so I could just say at least I got comfortable with it.
My experiences before the high flow air:
If the A/C was on the car felt like it would struggle to get going, and then accelerating was very painful. Even with out the A/C anytime I shifted and gave it throttle to accelerate I would feel a huge lag, would hear a heaving sucking sound then would have to wait for the blower to spool up again. And I kept bitching at my dealer because I was getting what I considered to be low pressure of 8 PSI from my blower when it advertised 10-11. After letting them do a full tear down and rebuilt they claimed they could not find anything wrong and the car still responded the same.
Now after the high flow air:
Car drives great. I feel like there is a lot more kick while accelerating from any RPM. When shifting I no longer feel the drop in power it holds power, I keep boosted and continue accelerating. With the A/C on the car feels less restricted. Obviously there is always a power loss when the compresser is running but it really felt smooth like it did not lose much at all.
Now the reason why I keep saying "intake" is because basically all I did was I went into pep boys and found a very small air filter that just barely fits between the s/c and the battery, oiled it up and for $15 I think it was the greatest purchase I ever did. So anybody who has the S/C and doesn't have an intake yet just go spend the $15 you won't regret it.
get a real intake and some water injection
lol for now that is how my intake is.
the filter is inbetwen the battery and the charger.
i just ordered a batter relocation kit. i am going to put a "real intake on" then add a heat block off plate to keep the engine heat away.
that plus the alky injection should really lower my intake temps
Well personally from all the tests I ever did in the past a "real" intake versus just putting on a filter there is no difference. I saw a slightly better throttle response in the car with just a filter than with the full tubing so I would rather stay with what I have. Plus I have the full intercooler setup which keeps my intake temperature down to cool temps at all times.
I'm not going to relocate the battery but when this one goes I will get the slim light weight battery to put in its place.
I am not going to put on a heat shield either because again from past experience it did not lower the temperature enough to validate the effort and it restricted air flow. No matter what anybody says I think the setup I have is offering me the best performance I can possibly afford. It's a double stack filter so I do have plenty of air flow going through.
Just went for a cruise at lunch too and I'm love the extra power that I appear to be getting. The fact that I can actually feel myself being pushed into my seat is a good sign since I have not felt that since spring with the cooler air. Once I get to the track I'll post up some times. I should be there Saturday assumnig weather is good.
the worste part is your filter is breathing air striaght from the radiator
ive got the aem on my g/fs and works like a charm
I really don't see a problem with that to tell you the truth. And looking under the hood the filter is pretty well protected from the radiator. There is a wonder steel bar that goes straight across between the filter and the radiator blocking direct access.
yeah but air comes through the radiator , and will flow up into the air filter , since the air filter is sucking in everything is can get
now if you built a heat shield around the filter so that it was able to only suck fresh air , instead of 200 degree under temp air , you would be alot better off
I'm betting that there wouldn't be a single gain at all. I bet the intercooler will take care of cooling everything down enough for me. And if I where to attempt to pull in cooler air it really wouldn't do much for me at all.
im will to put 5.00 on it
trying to cool 180 air plus what ever the s/c is increasing it to , will make the intercooler system less effecient , since it will only be able to drop the temp so much
unless your coolant temps are under 100 degrees , your loosing power
take a look in the tuning section , and talk with rodimus , he has posted that when the IAT temps are over 100 the pcm pulls the timing back quite a bit
Well I guess it is a good thing that my IAT was about 93 even on a day like today when it was 103 during my lunch break.
lol
just make up a heat shield to keep air off the filter , and get some from between the hood and top of the core support and see if your intake temps drop
you can use cardboard and mickey 1 up quick , i bet youll see a difference in iat's
For @!#$s and giggles I figured I would try exactly what you said. And my intake temperature did not change at all. I drove around parked the car blocked the intake so that the only air came from above the filter and under the hood. Drove around again and the air did not change one bit. Literally it was the exact same temperature.
might not have had enough room ida thought there was more room for air between the hood and core support
that or you forgot mans best tool , the duct tape
lol
might not have had enough speed to get the air flowing good enough
No I just think there really isn't going to be much affect. I mean after all it's not as much behind the radiator as you think. Most of the air being fed to it is coming straight through my front grill. And it is a hot one today. Maybe on a day where it is colder out there could be more of a change. But on days like today the intercooler is making the best it can do.
i know my g/fs the tb points down , and its near the radiator level
oh well , you tried
What kinda gauge are you using to get that reading on the IAT?? Im curious as to how its so low, I find it hard to believe your getting a IAT Temp of 93 at full boost, maybe at idle.
Check out my car....

It would be very beneficial to move that filter away from the radiator and have cooler air come in. Now my car is not boosted in anyway shape or form right now, but will be come spring (can not wait). Right now I have a CAI for an 02 that I modified for my 05. The airfilter sits down really low, under the car. With just that, I noticed a huge difference in the performance of the car. You may want to try something like that.
GIT 'ER DONE!

I am viewing the reading that is passing into the computer from my TMAP sensor.

I know what you are saying and I have been there before. I beleive that what I am running is the best configuration for my setup. the filter is not pointing down into the bay but flat toward the fender. And the air that flows through the front grill and pushed up and into the bay right by the filter so it is getting outside air. The problem with adding all that tubing is that I will just be waisting air flow time from the filter to the blower. I beleive it is better to get the air asap. Maybe on an N/A car you can spend time with trying to optimise your tubing, not sure if it is even worth it then, but my theory has always been the shorter the distance from the filter to the throttle body the better the response and performance assuming it is not in a dangerous location. In this case I have it sitting in a great location, there is a small adapter that I have to help prevent the filter from pointing down into the engine bay and the air is easily accessible for the fitler. Personally I think spending anymore money on piping or anything would just be a waiste. And for the HP gains for the $ I doubt that anybody would be able to match it assuming they would be able to actually gain more HP.

actually its 111 degrees, on the eco pcm when the IAT reaches that the PCM WILL start to pull timing its 2 degrees retard to start, and goes up, pretty much anything over 130 IAT is getting full retard prob 10 degrees of retard or more
Only the Radiator itself is going to be 180, the ambiant air around it is going to be much cooler, so the air temp that your pulling in will almost always be outside ambiant air temputure or slightly above. I have essentially no intercooling on my setup and ive never witnessed more than 117 and that was at 95 degrees in stop and go traffic, typically its around 80-90, but really the PCM treats it as all the same as long as its less than 111.

Thanks for helping out Rodimus. I don't think anybody ever realizes that there isn't much of a difference.
ECOnator, very good point. In that case shorter is better. The less ar flow time = quicker into the cylinders. Adding that tubing would do much if anything for you. Also looks like Rodimus got you going into the right direction, good luck.
GIT 'ER DONE!
I have a similar issue on my car which im currently working on fabbing up an intake for, my setup just has a cone filter right on the supercharger wheel, the placement is poor im working on trying to run it into the fenderwell with as straight of a shot as possible to not restrict flow

Just because intake air isn't hot enough to cause automatic timing retard, doesn't mean that it won't contribute to KR. Cooler air in, cooler air out, cooler air is never a bad idea.
