It was the same total advance. The way I understand it is your timing is much more stable and accurate with a crank trigger and that is where any increase come from.
I have never run one but I do have a MSD crank trigger and a BOP front-sideways distributor setup given to me by a high level bracket racer.
He took it all off and went to a nice aftermarket HEI setup. Much more simple, works just fine and he did not see a ET difference. 5-7 horsepower it would be hard to see anyway.
So I do not know if I will ever use the stuff either just bracket racing. I did my own test at the track years ago. Used PMD distributors. One with points triggering my 7-AL and another using a distributor with a Petronix setup and their coil. I used the same exact advance springs in both.
Ran the same ET-MPH with both so I sent the Petronix stuff back. Run points to this day. I tested the points (cast iron) distributor on a Sun machine once, spun it up to the max, kinda scary standing next to it. But it never had one hiccup.
Run that distributor ever since and have not had a ignition problem in my life at the track. The points contacts do not wear with MSD. Just keep a eye on dwell and I guess the spring could wear at some point. I run the 8000RPM points and I am never going to build a engine that can make them bounce anyway.
