Hey APS guys......
I was stewing the other day about ways to kind of maximize my setup a little more. Something that's always bothered me is the inefficiency of the little twin IC's in the kit. When we summertime tuned it last year the car was wanting to pull a TON of timing on the street because it was just heat soaking. So I got to thinking......
What if I was to add a side twin entry top outlet intercooler at the lower front like the some of the other kits have?? Keep the twins, just add this in. The piping is nearly right where it needs to be, just a refabbed shroud and way to mount would really be about the jist of it from what I'm looking at. Properly done, do you think this would be worthwhile to address, or would the potential for a severe pressure drop with a dual intercooler setup be too great?

I havent thought about a big FM and the twins, but I have thought about just a FM alone without the twin IC's.
Ill be interested to see if anyone chimes in with a little more knowledge about this kind of stuff....

I absolutely think it would be a worthwhile investment. 
Just get the intercooler from TTI if you can or something like it. What would be nice is to get Andy's ram air intercooler and just replace the bottom section to have 2 inlets. I know just the place to do that kind of job too. They specialize in building intercoolers.

Wouldn't you be creating too much back pressure?I would think that if it was that simple you would see a lot more cars with this setup.Not that that is a good reason not to try it.If it doesn't work I think going to the large front mount would help as long as you have a good cooling system.
Good luck.

I highly doubt my IATs are as high as Fastbirds because my Tigershark front fascia allows for DIRECT airflow to the intercoolers. I really have no way to log them though.

I doubt fans would do much to help. The problem is that they're just tiny intercoolers and are probably way past the point of being remotely efficient. Stock car, stock boost, sure. Built setup, not so much.
396375, it wouldn't create backpressure. I'd be more concerned about a pressure drop through the big intercooler.

a bigger more efficient intercooler with a lower pressure drop that does a good job of cooling the intake charge pays solid benefits
you can run more boost, and less pressure dorp increases the mass flow and charge density through the engine. intecoolers just can't be too good and getting solid airflow through a front mount should help quite a bit
I'm a bit biased as I have the ttix kit, but the intercooler is for sure a good one. kudo's on the tiger shark front fascia too as it does a great job of making the intercooler work better at speed
worth a try to be sure to measure the efficiency, you need boost "before and after" the intercooler, and IAT before and after
very revealing stuff never been a fan of the "twin coolers" except that they help the car run cooler. don't know much about how efficient they are, but the ttix and other front mounts I believe would be worth the hassle

Unless you're going with some crazy boost, the twin intercoolers on the APS kit have proven very efficient actually. I'm pushing 14 lbs in my car and there aren't any problems with pressure or effeciency from them.
The area that does need addressing is the piping. We've relocated the air filters a little bit so they don't sit right in front (and thus blocking) the intercoolers. Also, there's a few places in the intercooler piping that does create some back pressure. We've changed out all the hose clamps and a lot of the silicone hoses since the stock stuff is crap. The last thing I'm dealing with now is the intake side (from the air filters to the turbo's). It seems at about 14 lbs, the hose tends to callapse under the vacuum. These will need to be modified as well.

FYI, it takes some finagling, but the air filters will fit directly on the turbo's. That's what I've got done.

I do have the Pfadt mounts. However, I did have at least the drivers side filter on the turbo with the stock mount. Didn't try the passenger side until after the mount swap, but I would venture to say that it could be done with a stock mount too.
I'm actually in the "buying and testing" phase of several K&N Cone filters. There's a few that give nearly unobstructed airflow by design and leave tons of room around things.
