Here is my point validated! look at the bottom of the page and this is in a 4.7l not even 5.7l which will be harder on fuel. http://www.fueleconomy.gov/feg/bymake/Dodge2010.shtml man i hate it when i know what i am talking about.

Another aspect:

In relationship to the OP and what his plan involves,,,,

Have we forgotten the approx 30+ RWHP that are reported to be gained from this set up?

That's more RWHP for less $$$ than a set of AR long tubes,,,,, yet 'everyone knows' long tubes are 'what cha need',,,,,

Even if the new set up gave ya 42 mpg on the first tank, I wouldn't indicate 42 mpg to be 'the facts'.

Same goes with the 'proof' previously posted,,, Takes more than a tank or 2 to 'confirm' anything.

Heck, while we are all 'confirming' everything, will someone please confirm why my 30% blend with a vehicle modification cost of ZERO is saving me 40 cents a gallon,,,, with less than a 10% decrease in MPG,,,, and allowing me to run a 91 tune on 87?

As always, your mileage may vary! =)

that proof is factory dodge e-85 setups and you know they tested the crap out of their setup. im guessing its pretty solid. but we are back to the way to much money for hp gained. you will never feel a 30 hp increase in your truck its way to heavy. and your kidding yourself if you think you do.

Did you also see this page on the same website?

http://www.fueleconomy.gov/feg/why_differ.shtml

(Perhaps that's the page that 'confirms' my results,,,,)

Didn't see anything there that match's what the OP is doing either,,,

'Back to way too much money for HP gained',,,,'you'll never feel a 30 hp increase b/c the truck is too heavy,,,,

Wouldn't notice a 30 RWHP gain on a ~330~ OEM RWHP truck?

Dang, how much HP would it take for you 'to notice'?

In effect, you are also saying anyone who has purchased $1600 long tubes for a 25 RWHP gain has spent too much money and couldn't possibly feel any gain either?

We all have our opinions, no doubt, but you'll have a lot of folks differ with you on those two points alone.

No matter,,,, No ones opinions will change ours either. =)

You don't gain hardly crap with LT's..you gain torque. I went through this with my Lightning. LT's to me are great for a race setup and for some awesome sound but on the dyno they don't show near the HP gain as they claim.

Why are you running a 91 tune on 87??? And if your running E85..how is that 87? Maybe i'm not reading this right IDK....

man i have no idea what you are doing but it sounds like mixology 101 and something i would never try. But hey good luck with that. I am only speaking from real world experience on 100% E-85. Don not get me wrong i love the stuff and would use it again in a heartbeat but only on a race car application or a vehicle that came factory with it. man as far as the 15-30 rwhp increase i remember back in the day when i played with small mods and me and the friends would always be like can you feel it? the answer was always i dont know might be a lil snappier or better throttle response. i however do believe in small mods as accents to a big power adder in order to get that lil bit of extra flow needed because stock shit limits blowers and turbos way too much. a good power adder in my opinion is a a pulley swap that cost 50 bucks and added 40 rwhp or an exhaust swap that netted 40-50 rwhp for 400 bucks. all of my experience with this stuff is on cobras which are known to respond well to mods. I think the 5.7 hemi is a awesome engine and can put down some serious numbers if modded correctly but in a truck application i just dont see the reasoning unless its a lightning, a srt-10, or my favorite a srt-8 jeep grand cherokee.

SVT,,, I'm mixing 5 parts 'regular' 87 octane w/2 parts E-85 to obtain 92 octane fuel for 40 cents less than super unleaded.

Not too worried about mixing,,, The midwest is full of E-10, E-20, E-30 and E-85 pumps.

Been lurking in a couple E-85 forums,,, Folks have been running all percentages of alcohol in all kinds of non-ffv's for many years now. Some with conversion kits, some without.

Commonly reported that just about any modern (post 80's) vehicle w/o any alcohol related modifications will run up to E-50 with no CEL's or adverse mechanical / drivability issues.

What's also interesting is that some folks are finding that vehicles seem to have a 'sweet spot' when it come to percentage of alcohol. This 'sweet spot' is when the energy output of the 'mix' appears to be greater than the sum of the individual ingredients. 'Sweet spots' in the 20%-30% range seem to be the most prevalent.

Backing up a bit, when 'justification' for any mod is 'money saving', the up front purchase price is always a factor. The 'neat' thing about mixing is there is no upfront cost. It's just a matter of taking the time to see how your vehicle responds to different ratio's and then determining if it's meets you goals.

Going full blown E-85 in a non-ffv is probably 'best done' with a conversion kit.

Not sure what conversion kit the OP is focused on, but it could be from this company as it's the only EPA certified kit that I'm aware of: http://www.flexfuelus.com/

The 'balance' of the kits I've seen are pretty much based off of the plug and play kits used in Brazil for many years now to 'convert' their cars to Alcohol based fuels.

Basically, they plug into each injectors wiring and alter the pulse to provide more fuel.
(Usually done by adding a second, smaller pulse milliseconds after the original 'OEM' pulse)

Super simple install,,, The system uses the constant 12V 'positive' at each injector to power itself, and other than the plug and play injector connections, the only other connection is a ground. (injector 'pulses' are 12V 'negative')

FFI makes a kit sold by many different vendors: http://www.fullflexint.com/ http://www.driveflexfuel.com/index.php

Typically 8 cyl kit price is about $500.

One of the 'partners' in the original FFI group now sells his version,,, "White Lightning" for about $200. (8 Cyl) It has a potentiometer that you use to 'dial in' your injector signal.

Again, if cost savings is the major 'justification' for any mod, upfront expenses are a big factor. That reason, along with a desire to hear about the OP's long term results and truly not knowing what kit was the best 'bang for the buck' were several of the reasons why I opted to first go with the 'no-cost' mixing method.

Time will tell if it goes any further than that with me,,, Still got lots of time to be testing what I'm currently doing,,,

But,,,, be warned,,,,

There are days when,,,,

when,,, when I can't help myself and,,,,

and,,,



I mod just for the HELLUVIT! =)
