intake mod not so good.

[brisndl1]

so my first mod was a new air intake. heres how i set it up. 3'' stainless to k&n cone filter. i when i took off the OEM setup i left the ground scoop and the box half that is attached to it. i then fabed the new intake to have the filter set inside that right up against that hole for what i figured to be maximum air flow. first thing i noticed was increased throttle response. but when i timed my 0 to 60 i lost about 1/2 to 3/4 of a second. also at higher speeds when i floor it, it seems to struggle alittle. for instance, at 60 if i floor it , it seems to not want to climb to 80 like it used to. if anyone can help me out here that would be great.

i would assume this to be a 420a powered talon,well not really sure
what to say.the non turbo dsm's use map sens. instead of the karmen vortex
units found on the 4g63.Put the stock intake back on and see if
the car runs better.

Yeah I would try putting the stock stuff back on and seeing if that makes a difference. As for the 0-60 how many times did you do this? Your not going to get the same time each time you try it unless your a professional driver.

i did the 0 to 60 5 times each run and i avrege the results. im not sure if its the right way to do it but it seems to be the best way for using a stop watch to time.

You might have higher intake temps now than with the stock airbox. Atleast on the 2g turbos, the airbox has a snorkel to the fender so that it breathes in air from outside of the engine compartment. When you ditch the airbox, the intake breathes in hot engine bay air (that has gone through the radiator or been heated by the exhaust and other hot engine bay parts). It can be 20°F hotter even at 80mph.

Try making a long ram intake that snakes down into the fender or place it between the engine and radiator low in the engine bay so it keeps in the flow under the car.

If you live on or travel down gravel or dirt roads that pothole up real easy, I wouldn't put it too low unless it is down in the bumper between the wheel well covers and the bumper. Also, something that my friend Tyler and I did was fabricate an airbox around thefilter space and created a foam seal that met up to the hood. He has a turboed 420A. It worked great.

Good luck!

i will try building an air box \ heat shield. i will update later to share the results. also, i think i am going to install a hood scoop abouve the box i build. this will give the intake air flow from the snorkle and above the hood. or would that be pointless?

 

[1992awdlaser]

That wouldn't do anything. The only reasons to put a vent in your hood is for looks or to let hot air get out of the engine compartment. The heat wouldn't get out in this case since it is blocked off by the airbox you would be building.

If you want to go cutting holes in your hood, you could have the box mate up with the hood when the hood is down (maybe foam around the edges of the box to get a good seal to the hood) and draw air through the hood. But you really have to watch out for water getting in there when it rains. If you fill up your intake during a rainstorm overnight and crank the motor over in the morning, you'll hydrolock it. That's why the stock setup breathes from the fender well; it's cool air outside of the engine bay, and it's protected from rain.

I'd rather pull air up from below than down from above. And I'd rather not cut holes in my hood.

 

[marshall13]

Yeah, don't do the hood scoop. Build you an airbox and use foam weatherstripping or something to create a good seal on the hood. Some High temp spray paint will make it look nice and handle your underhood temps.

thats some thing i never really thought of. i will just build the box to match up with the old snorkle box so i can still use that.
