Has anyone tried the Alloy cylinders with Nikasil coating? The work of a couple different makers is shown below.
Cast
Billet
The clearance with 4032 alloy pistons and Nikasil coated alloy cylinders could be tighter than usual. I'm guessing around .003" to .0035" with an uncoated piston or .0015" to .002" with a coated piston as shown below . Has anyone tried this combo and with what clearance? Special order 4032 alloy pistons are shown below and they are amazingly lightweight at only 175grams for 73mm 750s and 183 grams for 77mm 850s.
