hello i have an 2003 silverado SS it has a 6.0 LQ9 i just bought a D1SC kit used and didnt come with injectors or fueal pump! so planned on upgrading them no matter what then me and my buddys were talking about me converting it over to E85 so that got me thinking is it worth the money is all i have to do is fuel pump and injectors or is there a bunch of other lil things i have to do please help! and i plan on putting a mild cam in also and a efans trans cooler shift kit and vette servos just so you can picture what im going for and if you any suggestions on a good cam please let me know thank

 

It's night and day difference in my truck on corn with all the extra timing I can run. Probably worth 30rwhp for me easily. And it's cheaper for me to run than 93, 30% cheaper but mpg only drops 25%.

 

It was night and day difference in my truck as well. It's a no brainer IMO especially if you are boosted.

 

I wouldn't switch. E85 is **** for consistenty. The specific gravity varies too much to rely on if your making anything over 500 hp. If you have the ability go buy e85 from 3 different stations and measure it.

 

e85 here i like it. truck has zero problems starting in 0 degree weather. has been consistent so far, but there is only 1 e85 pump within 20 miles of me

 

True, my Kroger "E85" station usually comes in at about "E75" (75% ethanol).

 

I love E85 for cheap race gas. I even switch my Chevy Cruze to be flex fuel (since it's a factory turbo car) and installed an alcohol sensor on it. Most places I filled up at were always right around e80 according to it. But even the little 1.4L loves the corn!! My current build truck (98rcsb fi) will be 100% e85 and looking for 800-1000hp out of it on the corn.

It may not always be true E85, but the good thing, that if it's less then 85%, that will just make your tune a little bit richer till the next time you fill up.

 

^ this. Run e85 also love it wouldnt run anything else.

 

Do you fill at the station on Voss road? That's where I get mine and in the summer it consistently measures around 83%

 

It won't live long at 1000hp using 100% E85. I have a buddy here that has an 8 second turbo'd Lsx 3rd Gen. Lost a engine to "corn" before he got serious about checking specific gravity, and blending fuel... Believe what you want, but I'm not gonna put blind faith in that ****...

I don't trust SG sensors either. I see about 5-8 a day giving wrong readings in SCR tanks on the tractor models I specialize on at work. The old hydrometer is a must in my opinion at high HP levels.
