cryo Posted March 14, 2017 Author Share Posted March 14, 2017 4 ports are supposed to be the best of both worlds. You can run a low spring pressure to default to during boost error situations but still hold a ton of pressure on the top side of the ewg to hold a ton of boost. We ran one on a EVO X running about 30psi with *iirc* a 10psi wastegate spring in a tial. In theory they are pretty awesome but I have not calibrated a ton of them since the 3port works great in 99% of the situations.

NSFW Posted March 14, 2017 Share Posted March 14, 2017 The 4th port is only usable if your wastegate actuator has top and bottom ports, which basically means external wastegate. Almost all internal wastegate turbos come with single-port actuators, so there's no place to hook up that 4th port on the solenoid. I think Borg-Warner has (had?) a 2-port actuator as an option for some of their IWG turbos, but don't quote me on that. Link to comment Share on other sites More sharing options...

cryo Posted March 15, 2017 Author Share Posted March 15, 2017 Yeah the efr series can have two ports on some if thier turbos. The evo referenced above was running a twin scroll iwg 7670 with a 4port. Not something that most will need to run their wanted boost levels Dave [sIGPIC][/sIGPIC] Providing unmatched customer service and a Premium level of Dyno/E-tuning to the Community cryotuneperformance@yahoo.com facebook.com/cryotuneperformance.

Wasted Potential Posted December 1, 2017 Share Posted December 1, 2017 Novice here, only know spring loaded waste gates... On an aftermarket 3 port, can one run a low Watergate duty cycle from Cobb with say a grimmspeed EBCS and that compensate for lack of pill? In regards to stock turbo, fueling, etc. Link to comment Share on other sites More sharing options...
cryo Posted December 2, 2017 Author Share Posted December 2, 2017 A 3port ebcs will always require a calibration after install. Hope that helps Dave [sIGPIC][/sIGPIC] Providing unmatched customer service and a Premium level of Dyno/E-tuning to the Community cryotuneperformance@yahoo.com facebook.com/cryotuneperformance.
