You may have difficulties reacing 16psi withouth a boost cut defender - Im not familiar with with the "stock" limits of pressure with the WRX. So, you may also want to invest in that.
I hope this makes sense to you guys. I just got my wisdom teeth pulled about 4 hours ago.. and im still feeling kinda free....  Wwwwweeeeeeee |
But the real problem comes at partial throttle. True at WOT, the injectors are wide open and the motor will be happy, even at higher boost. But at partial throttle, the ECU stays in closed-loop mode, and doesn't open the injectors all the way. Meanwhile your boost is up the wazoo (since the stock EBC is not being used) which means the car runs really lean. You start talking about EGT's in the 1600+ degree range!! :shock: Remember, your car is always fastest right before it blows up!
I believe the stock boost-cut on the WRX is 17psi. I'd be afraid to run boost that high w/o management since spikes can still occure, and will be in the 19psi range!! As it is, I'm only running ~15.5psi, just to keep my car happy. At this altitude, I could prolly get away with 17psi, but I'd rather not risk it... it's plenty fast enuf for me as it is!
