Got the Morroso catch cans already, but considering trading up to the IAG setup. DP is catted; I like the idea of not having to worry about getting someone to “pass” my annual vehicle inspection… Also, I’ve read that boost creep is less of an issue with a catted DP, and I don’t want to go full EWG right now.

I personally prefer using a MAF, however, there comes a point at higher power levels where SD has it's usefulness. For the most part, you lose resolution as you scale higher. In the case of a Subaru with a FMIC, you end up with so much piping that it can delay a MAF signal and then you need to vent it back into the inlet.
That’s true, it is technically twice the failure potential, but realistically I’m not too worried about it. Other than the scaling you mentioned, is there any benefit from using pressure in the manifold to measure the air rather than flow through the intake? I’m not set on a SD tune at all, but figured IF I should switch, I should do it all at once. (although it would be nice to be able to change the intake without needing a retune, but that’s small peanuts…)

My only concern with the temperature measurement being in the MAF, is that it has no way to tell what the actual temperature of the air entering into the engine is (post intercooler). And since the intercooler efficiency starts dropping in the upper revs and temps begin to climb, I don’t know how well the MAF tables are able to account for this. I mean it seems like a good idea to put the intake temp as far down the intake path as possible… Am I crazy, is this a waste of time? Have you tuned a car with a relocated intake temp sensor?

Wire in a separate sensor for a second IAT. You can even plumb it into an unused connector and display the voltage.

My personal opinion, there is zero need to go to SD at your power level. I'm still using a MAF.

So I got the DP in and a pair of gutted OEM TGVs and dropped them both off at a local ceramic coating shop. Not sure how they compare to swaintech but their product is impressive. As much as a 700-800*F drop in surface temps during their testing. But even if swaintech is better, this is cheaper and local(no shipping), so its good enough!

I might have missed somthing so sorry if this is in left field. One of our local shops likes to relocate the temp sensor to the bottom of the ic. Says it allows for a more accurate reading of the intake temp as its on the tb side of things.

They have a o2 bong welded in for it

Yeah, Ryan is the one who have me the idea initially anyway but I never really talked through it with him beyond it just seemed like a good idea... I need to catch up with him. I'll have to peel off some of that beautiful gold tape

Awesome work with the aero. If you consider making these available for others, you may be getting some of my money

It has been super busy lately, so its been a few weeks since my last post. I got the downpipe and TGV deletes back from the ceramic coater. They are currently garage ornaments, haha. Got the rear diffuser back from my friend after a month or so, and he basically said that the aluminum is too thin to try to weld… I pulled down the “phase 2” underbody panels to replace bolts with threaded studs so that I could “bolt” the stud to the car, and have a nut to tighten the panels against as well. I also got some XPEL paint protection on the hood and fenders, as well as the lower half of the front doors. And just this weekend I finally put on the new DBA4000 rotors and new DS2500s. I am going to bleed the brakes tonight to “finish” the brake maintenance . I’m going to the open house “parade laps” at VIR this Friday with the local Subaru group. Its fun, cheap, raises money for charity, and we go hit their karting track while we’re there

In other news, now that its warming up, I no longer have AC again… So I’m going to order some new seals and get it recharged, again.

Downpipe and TGV deletes are still hanging out as garage ornaments, but I have not been completely idle!

Last night I installed the Group N transmission mount and Kartboy transmission cross member bushings. A friend gave me a gift card as a thank you for building some built-in-bookcases and told me to buy car parts… You don’t have to tell me twice! Last night I pulled off the cross member and swapped the bushings. I was expecting this to kind of a pain and a little difficult, but it turned out to be super easy! Only took me about 1.5hrs and that’s including jacking the car up, and pulling off underbody panels (and of course reinstalling them).

I did have a minor heartattack when I pulled the OEM STI trans mount, only to see one that looks completely identical to the group N mount… I was expecting the new vs old to look something like this:


But I guess that’s the WRX mount, because after a little searching it appears that the OEM STI and Group N mounts are basically identical except for the durometer hardness of each. I should’ve taken a picture of the two for reference but that wasn’t’ on my mind...

I haven’t noticed any increase in NVH (engine mounts probably drown it out) but the car definitely drives smoother. Specifically the drivetrain jerking from getting on/off the throttle has be significantly damped. Honestly I was hoping to hear more gear whine, like with the shifter bushing install (I love that noise, #becauseracecar…haha), but it didn’t happen…

The gear whine is pretty awesome, I agree
I'll be buying the Group N Engine and Transmission Mounts when I'm in the US and bring them over in my suitcase.
WAAAAY cheaper than buying them over here.

But getting the jerking out of the drivetrain on/off throttle sounds good to me!
