This airplane reliably delivers 165 KTAS on my cross country trips. It has done this for as long as I've been flying it with the PMags and LOP. However, since the cooling mods I made recently, I have noticed some extra speed. On my first test flight it stabilized at 170, but I dismissed it as a fluke. However, I just returned from a weekend in Vegas and it delivered the same 169-170 KTAS on both legs. I'm running the same power setting, fuel flow, altitude, EGT, etc... The only real difference is the very much cooler cylinders (too cool now, actually - all under 300).
Not that I'm complaining about 170KTAS and 8.2gph, but it does not make sense. Any ideas out there?
