figure out how to run somewhat lean and have a decent transition.
Heat is power and it seems the best EGTs create comprises elsewhere as unintended consequences.
my #'s necessated NGK BPR7ES when BPR5ES became hot. It still lean pops on occasion. With thee BPR5ES it happened all the time.
I have 2 sets of BPR8ES and 2 sets of BPR9ES to continue this.
ps: I ran around the country for 20k and around home for 8k miles at "good enough" settings.
The point being is do you want it good enough or.. more ?
E-cams, 8.5:1, 34 vents, 55 idles, 135 mains, F-11 et's, 190 ac.
start rich and tune leaner and leaner.
