Turbo 383 in a A-body Barracuda
I am pretty sure with the big spring you will only be able to controll the boost from 15lbs & up or close to it. Have you bench tested it yet? You got me curious now on how it is going to act during the test.
I also lubed the valve and guides up with anti sieze...
I left the small springs in mine that are supposed to be 7lbs. I can control the boost from 4lbs to 40 lbs + on the bench test.
Hell, Now I am lost! I am going to look at what spring is in the box.
I left the tallest inner spring in I think. Seem to be the easiest one to compress!
So, you left the lightest spring in??
This difference with size(height, circumfrence, thickness??) is conflicting..
The small spring was a ***** to compress in the housing. My vise didn't open enuff! I should have took pics.
I just finished my B!tch Duties so I will go out to the shop later and check it out. I have a vacuum pump and tested the BOV. Started to open at 12..
Where are you running the hoses for the wastegate and bov? From the way it looks this BMC needs reference from the compressor housing then into the wastegate. I guess It will need to be installed under the hood near the wastegate. This will be pressurized so I think the length of hose is limited. They have a cable kit but it too is pricey. I wonder if I can run a set of hardlines into the cabin under the dash and back to locate the BMC.
Looks like the BOV is referenced from the intake below the carb so under boost it will pressurize the diaphram and hold the wastegate shut. BOV should blow at 12psi if it opens at 12 vacuum when off throttle? I guess I can tee from intake to reference boost for the fuel pump controller and the MSD Boost retard and the Autometer Boost gauge?
I think thats right??
So much to learn!! Gonna knock the cobwebs out a bit! LoL!
