Can someone shed some light on something, please.
After my recent and first trip to the track and being advised to increase the boost from 22 to 25, I tried with my Hallman Pro RX manual boost controller but with no success.
Today, I took the car out for more testing consisting of making a quick blast, watch what the boost reads, pull over, open the hood, turn the mbc clockwise and then making another blast to see if the boost moved. Did this several times. Took it all the way up till it stopped turning and then backed it off as I heard turning to full stop is dangerous. PS, my Alky was at safe levels to protect my testing.
It seems no matter where the mbc was set, down or up, the boost ranged from 20 to maybe 23. That's it. No more.
Then it got me thinking so I read up on mbc's and how the Hallman works.
Maybe 2-3 pounds is all the Hallman can add based on where the boost was baselined or where my adjustable wastegate actuator is set?
Could this be what's going on?
After all, the mbc can't have infinite or unlimited boost adding capability, right?
I also wonder if I have the wrong spring in there.
Should I turn the Hallman down and add more boost at the adjustable wastegate actuator and then start turning the mbc back up to get where I need?
Thoughts?
