E85 ?
Anyone running E85 in their hotrod? A couple of pros & cons would be nice or cautions or recommendations.
Thanks |

Required Fuel (ZL1 Only)
If the vehicle has the 6.2L V8 engine (VIN Code P), use premium unleaded gasoline with a posted octane rating of 91 or higher. For best performance, use premium unleaded gasoline with a posted octane rating of 93. You can also use regular unleaded gasoline rated at 87 octane or higher, but the vehicle's acceleration could be slightly reduced, and a slight audible knocking noise, commonly referred to as spark knock, might be heard. If the octane rating is less than 87, a heavy knocking noise might be heard when driving. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you could damage the engine. If heavy knocking is heard/ when using gasoline rated at 87 octane or higher, the engine needs service. Sent from a large Hammer.

It says less then 87 and it can damage the engine, I believe that will affect your performance and the knocking might also.

Of course E85 can be run with the right injectors and supporting mods.

Since it is very hard to get a good octane level and ZL1 is also not listed as a E vehicle you are probably asking for trouble.

Sven, I'm pretty sure this man is talking about upgrading with supporting mods to E85. I don't think he's just going to dump E85 without modifications.

Greg, you beat me to it, thank you for posting truth about E85. I believe the main requirement is going to be larger injectors (ID1000's?). Supporting mods to be a boost-a-pump and a tune. Keyword there is beleive... I've only seen one person on here convert their car to E85 but I can't remember who it was. It would probably be a good idea to contact a shop that has done E85 conversions. Check with Vengeance Racing and other shops on whats required. This is something I am also considering but I'm not quite ready to make that change, I'll be wanting two tunes I can load onto my ECM. One for 93 Octane for everyday use and one for the E85 for Racing.

Watch out for octane ratings for E85, they are rarely accurate.
