This is a slighty used mbc (black), I am selling this because, I decided to buy the HKS EVC kit, this is by far the best mbc I have ever owned, It holds a solid 21psi on my Evo, I hate to sell this but, it's time to upgrade to something fancy... The Hallman Pro RX Kit contains the Hallman Pro valve with a ceramic ball, both light & heavy (standard) springs, 3 feet of hose, mounting bracket, hardware packet, and complete installation instructions.

$60.00 shipped, I accept checks, and money orders only. Comes with everything you see here, but the unit is black.

 

Were you not able to hold anymore boost. I have a dejontool boost controller and it just wont hold more than 20psi to redline. I need like 23psi to redline. Have you ever tried to push more than 21psi?

 

I would make sure that this is a steel ball and not a ceramic one. I heard the RX is the ceramic. I believe the ceramic is good for controllability, but not good for holding higher boost. I ordered the steel ball with a heavy spring.

 

you've got PM

 

Do you still have this mbc for sale? I need a replacment ASAP for mine...
