The set-up eventually settled at 232hp at the wheels on a DynoJet.
It did pick up about 5hp at 35-degrees, but EGT's were just too hot for my liking - this was a dual purpose track / daily driver, so reliability was a concern.
Stock 20B, no turbos, stock 20B intake, engine was never opened up - stock 9.0:1 rotors, restrictive cone filter, FC chassis, custom tube header into a 3" exhaust, Haltech E6K, no split on trailings, BUR9EQ's in all 6 positions

Im just gonna take this and try to learn a little here.. dont mean to take away from the actual problem solving.
That sounds like pretty good number on an internally stock NA 20B. What are the reasons for advancing the timing in general? Also.. .cant running too rich lead to pre ignition just like running too lean?
