Corksport SRI & TIP
I just installed this unit with great expectation that it would improve performance. I've seen MPS owners extract out the OEM TIP and the restrictive piece of moulded plastic was enough to make me puke.
The Corksport unit is quite nice and the MAF housing is very light being billet. The AEM dry filter is a bonus as well.
The recirc hose attachment on my car had to be custom fabricated to fit but everything else fit reasonably well.
Impressions...
Noise - I had an Apexi SRI fitted with WRX MAF housing previously and it makes a high pitched jet suction noise and flutters on light throttle release. The AEM has an unusually pitched suction noise and quiet release of throttle. I hated the sound of the AEM and refitted the Apexi unit. It now sounds more Skylinish and flutters louder on light throttle release.
Performance - I am a bit disappointed. I think I've lost grunt. The ECU should have re-learnt this mod by now but my boost no longer spikes beyond 20psi and doesn't hold 17-18psi like before. It seems to hold 15-17 psi depending on load and spikes between 19-20psi.
There is no noticeable seat of the pants gain and judging by what my boost guage is saying, it has reverted to less boost. Power delivery pre install was more savage. Now it seems more linear which feels slower. Hopefully my ECU will continue to learn and restore my pre Corksport install psycho boost settings.
I think Nickows mentioned in a previous thread that his SRI/CAI install did nothing for performance. Same here...
