Who know's anything about Manual boost controllers?
I have a first gen Hallman MBC.
I contacted Hallman and had him send me an upgraded spring. I received it today. It doesn't appear any different than the one I took out. The stiffness & length is identical. I put something in the nozzle and then went to a digital scale, the ball breaks open at about 5 1/2 lbs of weight against it. Does that mean that if I have the PTE 18lbs wastegate actuator, that i'm only good for 23 1/2 lbs??? Or is 5.5 psi & 5.5lbs totally different?
Hallmans sites says for example that if you have a 10lb actuator and your MBC is set for a 2 psi differential, that you will have 12 psi of boost.
I can't figure out WTF is going on here. These are supposed to be good for 30psi.
Thanks for any suggestions.
