So without a boost retard working on this dizzy it would reach 26 degrees BTDC at 0.8bar potentially.

Just wanted to be sure you were considering this in the response.

I mostly here guys running less than 22 BTDC at 0.8bar from posts I been reading here on the board. But those numbers are all hard to come by.

1979 930 Turbo....3.4L, 7.5to1 comp, SC cams, B&B intercooler, Snow Perf water/meth injection, Rarlyl8 headers, Garret GTX turbo, 36mm ported intakes, Innovate Auxbox/LM-1, custom Manually Adjustable wastegate housing (0.8-1.1bar),--running 0.7bar max
