  1. Glad to hear it works for you, with no CEL. What year/make/model/engine? Thanks.
  2. Yeah, these measly gasoline compression ratios gotta go! Daily-driven 14:1 455?
  3. Incredible build. Yeah, I'd say the guy can tune! Did you notice that he said the car made more power and the turbo spooled more quickly with E85 than it did with C16? Awesome. He's parting-out that build, so I wonder what's next? 1000hp from a turbo Honda on E85?
  4. Thanks for sharing your results, SacramentoE-85. ;D I am enrolled in an Automotive Engine Performance course this semester and will have access to a 5-gas analyzer ("sniffer") and load-bearing dyno. I plan to test my car with 91-octane gasoline, then with E85. I'll share the results when I get them. Until then, your results give me hope that I will see a similar reduction in GHG-emissions by using E85. As a general rule, the complete combustion of gasoline (stoichiometric air/fuel ratio) in an internal combustion engine results in higher levels of CO2(versus a rich or lean air/fuel mixture), according to my textbook. It is interesting that your CO2 numbers matched for gas and E85. Gotta give credit to those GM engineers, apparently, because your Tahoe is achieving nearly perfect combustion with either fuel.
  5. Research Octane Number || Motor Octane Number || Anti-Knock Index (R+M/2) ethanol 118 96 107 regular gas 92 82 87 E85 (summer) 113 94 104 (numbers rounded to nearest integer) This is assuming that summer blend of E85 is 83% ethanol, by volume. Regular gas is 87 AKI in California. The RON and MON numbers will vary, depending who you ask! I have spent some time researching the topic on the 'Net, and have bookmarked and saved several documents; if you would like me to share, just let me know. Welcome to the US and to Southern California! In which racing series will your team be competing? When and where? I run my 2001 Corvette Z06 on E85, and have also converted my friend's 2003 Z06 to run on 100% E85. We get our fuel from the only known E85 retailer in San Diego County, Pearson Fuels.
