E85 ?

[UBNZO6D]

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.

Doh !!! - I knew all of that, but thanks...I'm talking for performance reasons of course.

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.

Thanks, but 'm looking for specific stories because of the use of E85 either good or bad...This would apply to people with much higher than stock HP.

He's talking about E85 (85% Ethanol) not 85 Octane gasoline which typically contains no more than 10% ethanol.

[Sven59]

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.

Thats what I was hoping, I have E85 octane levels are all over the place and not always calculated correctly and I am sure with that much ethonal the motor wouldn't like it unless.like you said was modified specifically for it. I would just be worried what I am getting out of a pump.

You are correct...I'm talking E85 Ethanol (85%)...In Socal, it's listed as 105 Octane...I'm looking for success stories using the higher octane fuel whether it be on a dyno or at the strip.

Thanks.

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.

Depending on blend used at different times of year, they are between 100 to 105.
