Stage 2 question

**TravTagz** · 10-11-2012 11:44 AM

In 1 week I have an appointment to get my turboxs catless dp installed and tuned on my 2012 WRX hatch I was wondering if I should get an intake at this point so that I can have them tuned together or is the stock box sufficient at this level, and any recommendations as to which intake others are seeing best results with? Car is stock aside from AP stage 1 map right now.

ran a 13.6 first time ever at the track and was suby vs evo day hoping to break into the 12s after this setup

If you have the money to get more mods before getting the tune... i'd do it. I got a DP and AEM CAI at the same time. I only got the CAI because Eric at TP told me that at stage 2 that an intake would add 3-5% hp. I also got a good deal on the new intake. I wouldn't bother getting a protune until I added a TMIC, bpv, 3 port and maybe even a fuel pump.... but that's just me. Protunes aren't cheap.

If you can get the AEM, go for it. Otherwise a short ram will be pointless. The stock box is better (unless of course you want some spooling noise).

Personally, I would stay with the stock air box if your going with a catless downpipe and don't have an EWG in your future plans. The car will be less prone to overboost.

You don't have a CAI on your set-up?

I watched some Aussie dudes but this idea to the test on a Mod themed video. Mighty Car Mods on youtube. I'll put a link at the end of this.
They dynoed a N/A car, a turboed Soobie (legacy wagon?) and showed the results.
They did stock airbox vs Pod filter and CAI vs stock in another.

I just thought I'd share those cause I didn't really believe it.

Yes, but I also have a catted downpipe. Some days I wish the stock box was still on the car because of how loud it is with the combination of the Forge BPV and AEM intake.

Time and time again, an intake on VFXX 2.5L engines have shown gains of 10whp or more with proper tuning. Not always at peak, but gains towards redline (especially with enough injector to take advantage of the additional airflow) can be impressive:
2011 Subaru STI stage 2 plus intake. Before/After intake test. - NASIOC

NOTE: The above car is an STI, but the turbo flows similar. While the TMIC is a bit better on the STI, this is just showing the before/after of an intake (obviously injectors were added as well, but Mike addresses that).

There has always been that CAI vs. stock box set-up. I just go with what Eric from TP told me. He had no reason to be biased about it. I wasn't buying from him. I just asked him which one he saw more gains from... he told as i've said before that at this level it was about a 3-5% gain. For the money (about 220.00 I think it was shipped) I think that 3-5% of almost 300 whp (or over 300 according to the VD which I don't trust) is worth it.

What other mods do you have that you're hitting 300whp? or are you just running an insane amount of boost?
