Remember, USA octane is RON+MON/2 = USA Octane, thus E85 is more like 96 USA Octane and of course 91 or 93 is 91 or 93 USA Octane.
Make sure you log some good 3rd gear pulls and see how your car responds to the E30 MAPs. |
Car feels great. No point in spending 9.39 a gallon for 100 octane when I can use 93 @ 3.89 and E85 @ 3.29 locally. The E85 says "85% ethanol" but the approval sticker (which would normally be octane rating for regular gas) said that it is only guaranteed to have a minimum of 70%. I mixed it (assuming the 93 octane was 10%) so that I am somewhere between E30 and E35.5 at both extremes so I think it will be fine. I am trying to reach my dyno guy so I can get it tested plus I may hit the strip this weekend to see what kinds of speeds I can hit in the 1/4.
