SEEMS LIKE A GOOD IDEA FOR THESE TRUCKS, WHO HAS DONE IT?
I am not sure if someone has done it to one of these engines yet.
SEEMS LIKE A GOOD IDEA FOR THESE TRUCKS, WHO HAS DONE IT?
One of thousands of reads... the article is now ten years old but...
E85 and Fuel Economy
(Don't forget to click on Numbers 1-7 near the bottom of the screen).
thanks, i read that article a long time ago, i used to own a 2011 h.o. 5.3l silverado crew cab with the 6pd auto and i have tried both fuels, i noticed the engine ran a little smoother with the e-85 for everyday driving people have dyno tested the difference between e85 and 91 in a flex fuel silverado and it would generally make 5-7 more whp with e-85, so if no one has done it to an srt-10, how would we know if it is better or not?:dontknow: i also wonder if it would be better for smog checks
You should do the conversion and post the results.
God I love the internet... You will with out a doubt LOOSE POWER converting to e85 with a n/a engine. The reason you can make more power in a boosted engine is you can turn the boost up due to the higher octane rating. Why do you think people are making more power on Vp's ms93? It's because is a motorsport fuel that doesn't contain the up to 10% ethanol that is required in your pump gas. If you want to make more power with e85 you need to increase the compression in your engine, it will only run you about 15k.
This goes right with people that say c-16 will increase power... it's just not true. They both allow you the potential to make more by increasing the cylinder pressure and heat needed to cause a detonation.
e85 also decreases fuel economy, because it make less power the engine needs more of it to maintain the same power output.
From a socioeconomic stand point it makes even less sense, you burn more fuel making it than it creates. It also caused a huge rise in the price of basic food products that led to major problems around the world. Making ethanol from corn is plain dumb, in brazil they do it with sugarcane.
E85 takes about 1.5 gallons to equate the BTU value of 1 gallon of good old gasoline. So unless your E85 is 2/3 of the cost of gas, you are losing money. You will consume your tank 50% faster. I've never seen the cost at this ratio, and people that are "saving $0.20/gal on E85" are clueless of the INCREASED cost to them. But then again, most of these people speak in "payments" not total cost. "I got me a used Montee Car-low, they wanted $2500 but I git it for only $100/month for 60 months."
However, I can't speak to the potential performance gains.
We are now having the option at the pump for non ethanol unleaded. (Again) newer pumps have a separate nozzle and octanes in one pump. So now there's diesel, E85, 10-15% Ethanol 87,89, 93
And now 87,89,93 "Ethanol Free" grades. :dontknow:
Me, 93 octane for 8 years and 155k without ever going inside the engine or failing a head gasket. Ran 12.1@112 on 93 octane Ethanol mix crap gasoline.
Stoich ratio is +/- 9.85:1 depending on ACTUAL ETHANOL CONTENT. Gasoline is 14.7:1. You have to consume an assload of E85 compared to gasoline. Bigger injectors, fuel lines, tuning and as said you'll gain nothing. Max timing on our engines with 93 doesn't even budge with 109 unleaded.whats that tell us? On a bolt on engine anyways, there's no need for higher octane. Now......bump the compression more and the need for a higher octane does exist or you'll retard timing and lose potential power.
Bottomline, performance and speed cost money.
