Default How much timing with MSD 6LS and boost??

Curious where to start out with the timing curve. The setup is an LS1 with 9-1 compression, h beam eagles, mahle forged pistons, hot cam, victor carb intake and a CSU 750 carb with A1000 pump. Otherwise stock. Has a D1SC Procharger and about 10psi, no intercooler. Setup is in a 67 nova with a tremec. I programmed the MSD6LS controller with 20 degrees timing across the board. Seems to run good. No A/F meter but TR6 plugs look perfect.Anybody have any experience with this? Eventually gonna get to chassis dyno to sort out but just want to make sure its safe to drive. Any guesses on HP numbers?

Ditch the projected tip plugs before anything else. BR7EF would be better.

From there, it is hard to say without a wide ban and a dyno tune is the only way i would go.

And where the hell did you get those brackets? Custom or a kit?

The brackets are from procharger, bought complete kit that way. They call it a retro kit i guess. I fowled out the BR7EF 's cruisin around at low rpms like a sally in the first 150 miles. Mike From Dez Racing where i bought blower from recomended TR6 's becuz of the low boost levels.

Sounds like a tuning issue, i run BR7s with a 150 shot and they are golden brown cruising everywhere all the time and beating on it. A proper tune should not be fowling any plugs.
