Hey Guys,
I want to see a list of what octane fuel your running with your mods and how much knock you are seeing.
What are people seeing with 89, 91, 93, and 105(E85).
The reason I ask is I started out when I first got my car stock and ran premium 91 and saw around 5-6 degrees knock at some times WOT. After that I started blending in E85 to make 93 that had 10% ethanol with about 2-3 degrees knock. After a few tanks of that I have slowly worked up and my current tank is an E85 mix with premium that is 28% and 96 octane. I just did a run tonight and had zero knock. Car seems to like it and I've had no troubles so far.
Premium 91 here was $3.30/gal and me mixing to get 96 was $2.85/gal which was nice.
