After seeing positive knock on 91 gas here in AZ I decided to go the E85 route. Unfortunately my knock readings are still positive (typically around 1-2 degrees from 5k to 7k). Is this actually an issue now that I have better gas. I have checked my catback exhaust and it has zero clearance...
Yup. I am in Tucson AZ and my IATs are usually around 12-15 higher than ambient with the stock airbox going 65 mph. This is when its about 105-110 out.
Are you guys getting LU47s for e85? Im being told we need them bc the injectors are the same size as the 14's and these coyotes flow more air. Im hoping for some July 4th sales.
Yeah, after emailing back and forth with Shaun I think I am just going to buy the larger injectors and go the E85 route. My buddy with a bmw 335 says e85 makes a world of a difference and is the way to go.
