And in response to the last post. The amount of land it would take to create enough corn to fuel America's cars is larger than the surface area of the Unites States. So start tilling your yard and driving about a quarter as much as you do now and maybe we won't need oil anymore.
Brazil uses sugar cane, but an even better solution is to use switch grass, which can be grown on marginal land ( land that cannot be used for farming ). Its ethanol yields are double any other crop and its dirt cheap to grow ( its bascially a weed ).
Could it power our current gasoline use? Heck no, but along with shale, electric and natural gas vehicles it could help us reduce or eliminate our use of foreign oil which would be a massive boost for our economy.

Filled my stock 2011 GS with E85 and got a check engine light within a couple of miles--any input? Didn't have the codes read yet but I supect lean condition or something to do with the cats. Ran my '92 C4 on E85 a lot--worked well until it got cool and it was hard to start.
In a STOCK LS3 you do not need any new hardware - Only a software (tune) change is needed. Our cars can except E85 without a issue.
I have documented all of this in my first post on this thread. Please review and then make any other posts if needed

Bobby, you seem to have good experience with E-85. Do you know of any basic issues / problems or extra maintenance when tuning a stock (2008) LS3 C6 for E-85? Usually if it seems too good to be true it is, and a 30+hp /tq gain seems very substantial to not have some kind of consequences or cons!?????

Yup I know that! Im just wondering when you add MODS and get re-tuned for them if your injectors will be able to handle that much more considering they are already at 90%. ?

Yeah he should be fine as long as he doesnt get heads and cam. The stock injectors can handle a good bit. I'm surprised he's at 90%. I don't suggest going over 90% but yes it can be done. LS7 injectors are even better. I got over 500 RWHP through an auto. Manual guys have seen high 500 RWHP #s safely on stock LS7 injectors.

You need about 30% more injector for E85.

Yes - The injectors are the same. I have read about multiple BASE Z06's getting 500whp with E85 only without any fuel upgrades. It might not be completely "safe" but it can be done. I'm getting headers with stock injectors pumping E85 no mater what. I will be sure to document my results and see if I need to bump up the injector size.

I know you are looking out for me! Once I talk to my tuner I will give you his input. I won't do anything until i tell you what he suggests.

13.5 cr, big cam and 80 lb injectors will get you huge gains in power on E85.

I responded to the other thread with more info about injector sizing. It isn't just a flat "you need this injector" it has to do with how much power you're making.

I am actually hoping to install a exhaust system by next year so, that's when I planned on updating the thread. In respect to reliability... Track tested... Mile tested... it's been 100% flawless.. To all the naysayers, my gas tank has not melted!
As long as you have a good tuner that understands E85 it's a must. This has been my funnest mod I have ever installed, and actually the easiest! So many cool conversations arise with strangers at the pump
.Any other questions?

No further questions. I'm already at almost 500whp (494) so I'll need a bigger pump and injectors.
Any clue what kind of hp numbers I can expect going to E85? Is it a set % bump or does it depend on certain things?
