Installing Turbo Filter with Heat Shield on 420a Turbo Talon
This is the New air filter for the 420a Turbo Eclipse / Talon . The one I had was used from a previous car that had been turbocharged that just so happened to fit the space requirments of the little cubby above my intercooler piping that wraps around the bumper. The air filter on allows a single point of entry and is sealed otherwise. This is a slight advantage because you can stick its nose far in a cooler corner and get cooler air. Given the air may only be 15-30 degrees difference from the previous open air filter, for every 10 degrees you drop the intake temp you can get 1 extra HP. Another important factor is "what" you filter sucks up. As you can see a couple photos down. Read on...
The APC closed box yet nifty packaging, yep it worked on me, but funcionality is the key. Price at Advance Auto Parts 49.99
Top Comparison Picture, Both are pretty, One is shorter and more direct with airflow path, APC turbo air filter draws " straight through" while the other has a 2" area for straight draw through and the rest is side draw. This creates alot of turbulance and changes intake sound to more of a roaring loud engine verses lower engine sound with a upcoming whistle accelerating in every gear.
Here is the root of one of my largest problems. Just for the sake of good looks you face the Heat shield Down, However on the front you have the radiator, where air is pulled through the hot radiator and into the bottom of the air filter, very ineffective and preventing the airfilter from sucking up preheated radiator air. Also when it rains small amounts of water were sucked in from the bottom side caking the bottom of the air filter with road tar, this stuff is hard to clean out and has to litterally be soaked in a degreaser. Note this is after about 450 miles of test driving.
Direct Comparison from the top. The cuylinder air filter may have better filtration over all however all the air has to make several tight bends around edges and the another bend to turn into the turbo intake. The Turbo Filter has a more direct and smoother yet obvious aproach.
Turbo slings small amounts of oil out of its bearings, I will reasearch this and call Turbonetics. I have heard from ricers this is normal, but they are also reffering to a turbo that has been used before getting it. However dispite the film of residue the actual compressor is as clean as new after the 450 miles of test run.
This is the air filter facing the farthest from the turbo and exhaust manifold ( which produce hot air through radiant heat) and the bottom of the filter is closed off reducing the amount of hot air drawn in from the radiator. The only thing to remember is to have 2-3 inches away from any objects in front of a directional air filter of this type as 3 times as much air as to flow through the TIP of this unit over the standard " side draw" filter previously used. For me this is hard as the intercooler piping was made around a standard filter and this one is 1-2 inches wider. Knotching the edge of the fan shroud should give another inch of space without compromising looks or functionality.
