heat range for compression ratio of 11.5 and..,
Sup,
My compression ratio will be 11.5 w/ my combustion chambers, valve faces and piston tops ceramic coated by http://www.polydyn.com. This will increase thermal efficiency but also raise combustion chamber temperatures. What plugs should I be using for this set up? I know about bcpr7es11 and bkr7en11, but is there a higher heat range? Thanks.
