    Just ordered my Cobb AP

    Heyo!

    This is mostly a brag thread, but I'm just so excited that I finally pulled the trigger on the thing I had to share. I think I'll put an order in for the AEM intake shortly thereafter. It's pretty interesting...the Cobb website shows VERY small gains between the stage I AEM setup and the Stage II setup.

    I also picked up a set of the kartboy shifter bushings and the kartboy delrin knob with a red kartboy shifter, so we'll see what a difference all that makes. I'll be sure to write up a quick review of my impressions of all of these.

    All I need for the Stage II setup is the DP...but on cobb's website the dyno charts seem to show that the Stage II setup only offers minimal gains over the Stage I + AEM.

    Idk...maybe it's worth 500 bucks just to be able to claim Stage II

    I've heard that even some COBB techs have recommended to just do the Stage 1+AEM over the stage 2. Congrats, you love it (but.... you'll just end up wanting more)

    There's more to it than just the the peak values; it's the area under the curve.



    In the low-end, there is 35wtq difference between the two.

    It's that stretch from 2500 rpms t0 3500 rpms where the Stage 2 would open a real world lead on stage 1/AEM, and take it with each shift.

    You are exactly where I was about 6 weeks ago. I decided to find a used DP to complete the Cobb stage 2 + AEM. The drivability between the two setups is night and day IMO. If you frequently encounter stop and go traffic the low end torque is very helpful not to mention just more fun.

    After a few months of trying not spend any money on my car I am giving up. Going to order the AP from Perrin. Comes with a Perrin stage 1 map and foam drop in filter. I would really like to have the power gains from going stage 2 but I don't really want to be changing parts on a brand new car already and I really like the sound level of the stock exhaust.

    So, until I can hear a turbo back exhaust I like in person I will be at stage 1.

    I probably should have mentioned that I have to run the 91 octane ACN maps...in which there is an even smaller difference between stage I+AEM and II than on the 93 octane. By all means I think Stage II will be quicker than Stage I.

    But lets be honest...at some point the car will probably go Stage II with a pro tune. It's too addictive.

    My AP and shifter bushings are sitting at my front door right now (and I'm not putting the address up here ) waiting for me when I get off work. Can't wait to throw these parts on.

    Actually with the 2011 WRX's you don't even need a CBE. You can keep the stock CBE and just replace the downpipe with one with a high flow cat. That's my eventual plan...Stealth Stage II.

    That is probably the route I am going. Talked with a tech from Cobb today and he said the gains are minimal from a cbe when going stage 2. He did mention you should not be doing any top speed runs or spending an extended amount of time in the boost with a dp + stock cbe.

    Also, I looked at the dyno graphs for Stage 2 vs Stage 2 +AEM and looks like the intake is not worth the money. Ya, it may add a few hp on top end but that's not important for a daily driver. If you look at the torque curve from 2500 to 4500rpms it looks almost identical.

    I need to decide between Cobb AP stage 2 with Cobb DP or Cobb AP with Perrin Stage 2 map and Perrin DP. DAMN THIS FORUM IS COSTING ME MONEY!!!! Hahaha!

    What is the reasoning for that? I mean, not spending extended time in boost? why would you do something to your car that would keep you from using boost?

    He didn't give an exact reason. It does not keep your from using boost. I mean come on, when are you going to be in full boost for more than a few seconds at a time?? Even if you did 1/4 mile passes or auto crossed your only into full boost a few seconds at a time.
