I will be running a Gen 2 2.3 Whipple at roughly 17psi of boost and would like some opinions on spark plugs and Gap.
On my Ported Eaton setup, I had NGK TR6 gapped at 0.32. Should I stick with the TR6 or go to the TR7?
Does a 0.25 Gap seem too tight for that setup?
Then a matter or Copper vs Iridium?
