[QUOTE="Ironhand, post: 9705095, member: 32955"] 700rwhp+ is done all the time with 03-04 4.6Ls with a single 76mm Turbo. 15-17lbs of boost and 15-17 degrees on timing on 93 octane and 8.5:1 compression. Since you are using a turbo it is actually more effecient to up the boost to make up for the lower compression because the turbo will make more then 2% more power with the increase in airflow ie boost or the additional timing u can safely put into the car due to a lower static compression ratio. Yes it is possible to run 9.19:1 with 20 psi on 93 pump. However that will come at a cost. Cost of extremely low timing, sluggish spool, and poor throttle response. In those guidelines, 15psi with more aggresive timing with produce more power then your 20psi. Mainly because all of the timing u would be able to add at the lower boost pressure. [/QUOTE]
