Timing request 100 shot 360

Many thanks. I'm thinking I will start at 28* then. Wow. huge difference for your old nitrous motor. 11.0 is fast imo. 13.8 pretty good too.
11.0 was on the 180 shot if I recall correctly...and yes, Colorado air is thin, and the DA in the summer goes over 9000' on a regular summer day.

My current stroker motor runs low 10's NA on e85,....needles to say, I like the current motor the best :)

Edit: Don't forget to run a colder plug than normal, like an NGK -9 or possibly -8.
