First two sets of a new run of 95mm cylinders for 2.0-2.7 case. Obviously, a 7R case offers the best cylinder/head stack stability
They are in essence a 2.7 cylinder bored to fit a custom Ductile iron sleeve.
The completed cylinder is then Nikasil coated.
The special order CP pistons will run 4032 full, circle pistons with a 10:1 compression.
On a 66mm crank it's a 9.5:1, 2.8 and on a 70.4 crank it's a 10:1, 3.0.
The challenge was to source a set of rings that fit a ring stack I wanted in this low expansion piston and still be compatible with Nikasil coating.
