| best power at 36 degrees of timing advance. Higher cylinder pressures as a result of forced induction are going to speed up the combustion process and not require as much timing advance as a naturally aspirated engine, which is why I left my advancement numbers in my explanation to the 30-35 degrees I mentioned. FWIW, stock turbos with race fuel and all the other supporting modifications will make 400+ RWHP ONLY at timing advancements of at least 28 degrees. WHen I made the 411RWHP pull with my Z on stockers, I was pushing 33 degrees of timing advance. It wouldn't make that kind of power at anything less. On Z's pushing higher pressures and airflows than stock turbos, you can't run this much timing advancement because there is considerably greater pressure and density in the CC at the point of ignition, which is restating what you said.. So yea, I agree with you. :)
