Code Posted October 15, 2015 Share Posted October 15, 2015 this is a good spot for Q&A not related to the GB threads I will be attempting to install this with the Racer X FMIC.

TheMonaLisa Posted October 15, 2015 Share Posted October 15, 2015 Anyone install this with the Perrin inlet? I ask because the inlet does not fit perfectly on the 05-06 model years. Link to comment Share on other sites More sharing options...

serx7 Posted October 16, 2015 Share Posted October 16, 2015 I have a Perrin inlet on my 05 OBXT, installed summer '14. Not sure if it's the WRX style or not but it wouldn't allow for reconnection of the stock bov/recirc hose. The GS CAI fit to it w/o any problems. I had a harder time finagling the MAF wiring loom w/ the GS enclosure bc of the GM/AEM IAT sensor wiring I have that's spliced into the stock wiring (not a problem on GS' end). https://www.dropbox.com/s/cnhzyz0q2vo62xd/photo%20oct%2014%2C%204%2056%2016%20pm.jpg?dl=0 Link to comment Share on other sites More sharing options...

Chris GTO TT Posted October 16, 2015 Share Posted October 16, 2015 My tune is scheduled for the 23rd! That means I'll have to get the fuel pump done this week and then throw the 3 port and intake before heading to the dyno. 2003 Baja 5MT 2016 Outback 2.5i Premium w/Eyesight Link to comment Share on other sites More sharing options...

Chris GTO TT Posted October 16, 2015 Share Posted October 16, 2015 Having Travis at Snail do your tune again? Yep, the only reason I bought this intake, the 3 port and the fuel pump was because of the free tune I won at BAM. 2003 Baja 5MT 2016 Outback 2.5i Premium w/Eyesight Link to comment Share on other sites More sharing options...

Sent from my iPhone using Tapatalk Did a test install, and everything went where it was supposed to, although I didn't doubt it would. The power steering hose touches it a little bit, but it's minimal, and if i played with it a little more, I bet I could make it not, but i just tossed it on to see the install time (bout 15 minutes to get the filter on right and feed the MAF wiring through, did the edge seals beforehand) Link to comment Share on other sites More sharing options...
TheMonaLisa Posted October 17, 2015 Share Posted October 17, 2015 In the install video, they explained that if there is contact, rotate the intake pipe towards the front of the car. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Code Posted October 17, 2015 Author Share Posted October 17, 2015 I test fitted everything today. The air box and intake fits with the Racer-X FMIC. THINGS GET PRETTY TIGHT where the p/s lines and FMIC piping pass below the intake tube. I am going to insulate the pipe with a sacrificial silicone coupler to eliminate any chance of rattles due to vibration.

serx7 Posted October 17, 2015 Share Posted October 17, 2015 I installed the GS CAI a couple of days ago, and applied a 12% MAF scaling increase. I haven't seen any knock in single gear pulls, so i've been laying into it more and more lately. I did see some shift knock w/ 3500-4000 rpm upshifts which I've always gotten in cooler temps, but applying a 12% increase to throttle tip-in to 'match' the 12% MAF scaling increase seems to have definitely helped w/ reducing occurances of that. My car is a 05 OBXT w/ VF52, GS CAI , Perrin inlet, IPR TMIC, GFB Respons BOV, GS EBCS, DW740, DW65c, Invidia catless UP, PnP/coated collectors, Cobb catted DP, Nameless Performance resonated mid/Y, stock mufflers. Peak boost target is 19.7 psi tapering to 16 by redline. Anyway, on the way home tonight I was driving past my usual datalogging spot. I'm normally coming onto the roadway from an entrance ramp where I can do a 3rd gear pull from ~2200 rpm, but this time I was already on that stretch of road. Since there was light traffic approaching about 1/2 mi behind, I could only slow down enough to start a 3rd gear pull from ~3700 rpm. I loaded the datalog into an airboy spreadsheet and compared the results to a recent pull w/ the stock airbox w/ similar intake temps (~66F) on the same stretch of roadway. Since this was 3rd gear instead of 4th and since this section of road is slightly uphill (~3% grade), the road dyno plots presumably read a bit lower than they would if on level ground and done in 4th (2 yrs ago the car made 303 whp / 339 wtq in 4th gear on a Mustang AWD-500-SE dyno). There is a very slight undulation in the road that I pass when the motor spins towards 6k rpm, which show up in the road dyno plots. Also, when stabbing the throttle in the 3500+ rpm range I'm seeing boost spikes > 1.25-1.5 psi which I haven't yet had time to dial out, so for tonight's pull I rolled onto the throttle at ~3700 rpm rather than flat out matting it, and boost overshoot was a much more reasonable 0.5-0.7 psi around 4000 rpm. Airboy road dyno plot overlay should be attached to this post. Blue curves are wtq, red curves are whp. W/ the GS CAI, it looks like I'm seeing 15-20 whp / 15-20 wtq gains w/ tonight's 3700-6600 rpm pull, with the gains increasing as rpm climb above 5700. I haven't had the car protuned for the intake yet, but suspect the MAF scaling needs to be bumped slightly b/c I'm seeing 0.75-1 psi more boost above 5200 rpm compared to w/ the stock airbox, yet calculated engine load is the same. A contributing factor appears to be that w/ the GS CAI installed, MAF Voltage is slightly lower than w/ the stock airbox. I don't expect this to be a problem b/c open loop fueling from the original protune hits its richest values at loads above 2.66 g/rev, and I'm well above that through the entire WOT pull.

fahr_side Posted October 17, 2015 Share Posted October 17, 2015 ...applying a 12% increase to throttle tip-in to 'match' the 12% MAF scaling increase seems to have definitely helped w/ reducing occurances of (shift knock) Just curious. On all the ROMs I've seen, tip-in compensation is done via injector pulse width and throttle angle delta. I don't recall having seen any tables with one axis as engine load or mass airflow.

serx7 Posted October 17, 2015 Share Posted October 17, 2015 Sorry, I didn't mean to imply there was a link b/n TIE and load/MAF. While doing a bunch of datalogging to/from work, I noticed that w/ the original TIE values, I was seeing AFR swinging to the high 11's a bit longer after engaging the next gear w/ the GS CAI than w/ the stock airbox, under similar operating/shifting conditions. I do not have a WBO2, so I realize this is a course analysis at best. What I did notice however, was that almost every one of the 6 to 8 1st-4th shifting intervals on the way to work, exhibited FBKC a split second after each gear shift when I was applying 40-60% throttle. W/ the 12% higher TIE, all but 2 of those 6 to 8 1st-4th shifting intervals were shift knock free during the drive home. Might simply be coincidence, and I do plan on reverting the TIE to see what happens. I recall a pretty exhaustive thread related to shift knock w/ I think LittleBlueGT et al which resulted in ppl pretty much giving up on trying to tune it out.

xtea Posted October 17, 2015 Share Posted October 17, 2015 I am finishing my jmp52 tune with cryo soon. I've got maybe a couple revisions left. When we are done we'll add the intake and dial that in. I should have good comparisons also then. Link to comment Share on other sites More sharing options...

Oh, I see. I do not have a WBO2, so I realize this is a course analysis at best. May I ask how you plan to accurately scale the MAF without a WBO2? Have you moved your front O2 into the downpipe?
