Stock 1600 twin port supercharger conversion in my early VW bay bus that I am developing as a kit.

This is a shot of the boost. It's reading about 7psi although the engine wants to stall when on boost so I'm not sure if this is the max or if it's possibly got some more to go.

I managed to take the bus for a drive and found that it's pinking (detonating) really bad so I'm guessing that the main jets are far too small ( I'm running a Dellorto DHLA.) If it is leaning out on boost / under revs this could possibly be the cause of the stalling. I really need to get some bigger jets before I can progress any further
