Hey, welcome..... My name is Brian "MoparPerformance" and I also have a 2002 Intrepid w/2.7L "SE". I am currently in the process of "Project Trep 2.7L". So far I have installed a K&N performance Intake and Dynomax Performance aftermarket exhaust. I think I could be puttin' out around 215-220HP right now and I will be dyno'ing soon and will share the results.
I am currently in the works of testing BOSCH Platinum 4+ spark plugs out for this engine. I will then soon later install an ASE chip after working with ASE to "tune it down" so I will only have more like a 10HP increase instead of the 22HP so there will be less stress on the engine.
I am hoping to have newer Chrysler PCM/TCM revisions flashed. I am also going to be installing R/T springs and stabalizer bar.
I hope to to get around 230-240HP out of it. I plan on taking it to the track against my dad's 4.6L Mustang GT, he'll beat me but I wanna go at it with him. I also hope to provide video footage of that and track times as well. My ultimate goal is to make this a mean fuel efficiant machine that can keep up with an R/T.
As far as the K&N Intake kit.... Here's a video you can download for you to see the results yourself and decide if you would want to go with it.
For best viewing, right click on the video link and select (Save Target As), and save it, then play it.
I think it sounds pretty raw w/some nice performance....
