Whoa...hold on guy.
Intake placement has hardly anything to do with your fuel trims and air/fuel ratio.
Intake placement is also all about personal preference.
For a stock to 3.4" setup you want the intake farthest away from the motor as possible...why you ask? Because you want to be making the most power as possible since your car isn't making much anyways. It is when you get passed that 3.4" setup is when you want to go with a big open cone filter...because at that point...Flow>Ambiant Air Temps...plus...get rid of that 180* unless you have a tune...it will do nothing but harm your MPG's since your fans aren't set to turn on at lower points. PCM recommendation? Get one from 3800 Performance...DHP is the best mail order tune out there...PERIOD.
I suggest the open cone if you want more throttle response and more blower whine...but your not really going to notice a difference either way...just do what you want to do...its not going to change anything but the placement of your right foot.
If you want MY HONEST OPINION...I'd put an open cone on just about anything with a Roots blower...why? Because its going to get stupid hot no matter where the intake is...unless your intercooled...so...do what you want man...but just keep it mind...it won't change your A/F ratio...or your MPG's really...unless you beat on it...which with more blower whine...you will...TRUST ME
