I did a search first, and did not see where this has been addressed previously. Please forgive me if it has.
I'm wondering if any of you SS/SC Goblin guys running E85 have experimented with different spark plug heat ranges. According to what I'm seeing online, there is conflicting information regarding spark plug heat range recommendations for running E85.
My donor appears to have a Stage 2 installed, but I am not certain - as it is an auction car. It definitely has a ZZP 2.9 pulley and ZZP dual pass end plate. Not sure on the injectors yet, but several other bolt-ons, as well. Increased boost usually requires a colder plug, and I'm not yet sure how E85 affects spark plug heat range. I ordered and received the standard AC Delco Iridium Plugs (41-106), but am wondering now if that is the best choice for running an LSJ with a 2.9 pulley and E85.
Do you have any experience with a similar setup?
