FULL-RACE 4 PORT MAC BOOST CONTROL SOLENOID

Our 4-port MAC boost control solenoid valve is designed to target a clearly defined boost curve and improve boost responses, and in some cases with a soft WG spring—quicker spool. The 4-port design works equally well in low boost and high boost applications. The 4 port MAC differs from a traditional 3 port MAC BCSV (boost control soleniod valve) because it precisely directs pressure to the open and close ports of your wastegate diaphragm. This allows for a much lower wastegate spring pressure for better low gear boost control and perfect high gear, high boost control. Low gear boost means more traction at launch and lower gears and higher boost at higher gears when traction is usally less of an issue. This is commonly refered to as "boost by gear"

  • MAC Part number – 46A-AA1-JDBA-1BA

FEATURES

  • Better spool-up time and mid-range power
  • Better duty cycle control to hit target boost and hold
  • The solenoid is normally closed so that on failure you will run off the waste-gate spring only – to prevent over-boosting.
  • 1/8th NPT fittings

COMPATIBILITY

  • Ideal for use in sealed Dual Port Internal WG applications, Internal or External
  • Hondata S300, K-Pro or Flashpro
  • Cobb Tuning AccessPort
  • All PWM modulated standalone and piggyback ECUs will support this 4 port BCSV!

Note: 4 Port MAC Boost Control Solenoid must be mounted upside down on B2 EFR frames. This allows the exhaust port to point towards the wastegate nipple. Use our mounting bracket.

  • Full-Race Vacuum/Boost Block
  • BorgWarner EFR Wastegate Hose Kit

Dogs love them
Style: Ball, Size: Medium (Pack of 2)
Our dogs love these. What’s great is that you can add more plastic (like from water bottles) if the plastic starts to fall out from the center. If you have a chewer, though, these won’t last you long. Our shepherd mix loves these and then starts to pull the rubber apart the more she plays with it. Our other dogs treat it normally, though, and those ones last forever. They also get some decent height when bounced, and they make a unique whistling noise when thrown.

Our pup loves the cronch cronch!
Style: Ball, Size: Medium (Pack of 1)
I bought our 15 month old Coton several Chuck-It toys on an Amazon deal. He is incredibly playful, mischievous, and ball/toy obsessed, especially for anything that makes noise. He can also be very destructive so I love how durable most of their products are - they’re among our longest lasting toys and worth every penny. We have yet to take them to the dog park, but they’re a perfect size for sharing in play time. And they are keeping him busy at home - that’s a good thing. He loves investigating the crunchy-cronchy-crinkly sound which is a nice change from squeakers. It can withstand his destructive chewing well-being, gentle on his little teeth. I love that. Chuck-It is thinking outside the box with a variety of balls to keep dogs engaged! I do worry about the crinkle plastic inside because it is accessible because of the air holes and it feels a little sharp. So this will have to be an at home toy so we can monitor his play.

My dog loves it!
Style: Ball, Size: Medium (Pack of 1)
This crunch ball was a Christmas gift for my 65lbs fur baby. It’s now mid April and he still loves it. He loves running after it and chomping down on it. It is still in good shape despite all the chomping it’s gotta . I highly recommend. He goes back to this toy agin and again! Great buy.
