Why not straight E85?

[StinkinLinkin13]

So if you have a sufficient aftermarket HPFP (more volume/psi)... Whats preventing guys from running straight E85? After speaking with a tuner (intentionally unnamed), E85 would only be tuned/used in conjunction with meth injection... which to me seems counter productive as far as wanting to avoid using meth altogether... Still running out of fuel at that point? Injectors limits? Engine hp limit?

So you talked to LMS... but I digress...

We have the injectors and the pump. The fuel lines are adequate according the Gearhead. The part that is holding us up is the in tank low pressure pumps that sit in the saddle. They are your basic canister style fuel pumps which if we had a shop willing to look at them, could be an easy fix.

I had a spare pump I sent to BPD1151 for reconditioning and I THINK to be possibly modified to support more fuel flow.

That’s it at this point I believe....

I wondered when that pesky LPFP might come into play. I knew we have the "transfer" unit and the LPFP. Not to mention the LPFP module. But I guess thats the game... I'd really like the ease of running e85 which is readily available in my area. Its an easy pump to get to with access panels under the seat but I've yet to see any aftermarket upgrades... Oh well... The saga continues I guess. Trying to figure out which way I wanna go next with this thing.

There has been an existing LPFP solution for some time now.

Ok. Let me rephrase... a DROP IN solution... not an auxiliary one.

Fair enough, but do you not have to drop the fuel tank to swap it out?

No. Just pull the rear bench seat cushions. You can swap it out in under 15 minutes with little to no mess.

Nice.  They took away that option on the Edge in 2008 i think.

Can you enlighten us pheasants?

EcoPowerParts sells an aux fuel kit. But heard rumors he doesn’t anymore.

Maybe being local he could point me in the right direction.

I would think that if the lpfp was the issue someone would have engineered a higher volume one by now. With the cost and effort of making the HPFP to leave us sold short with no lpfp upgrade seems obsurd. To run E30 and pay all that $$$ is a tough pill to swallow. I just think it makes no practical sense to have to introduce Meth injection again to run e85. Defeats the point/simplicity of trying to run E85 only... Unless theres more to it than just the lpfp.

There are some built in functions in the tune to ramp up the flow like what people do with the mustangs using boost a pump modules. I wouldn't bother trying to upgrade the low pressure fuel pump until you actually see a problem.


Fomo here is running E85 at around 13-14 psi if I remember in his Lincoln and I think we even did some E85 in his 15' SHO if I remember. ALso I have a few other full E85 tunes going right now.


But yes I agree if you are needing to spray meth to help with fuel flow it's kind of silly because if you spray meth on 93 you get all the octane you need plus cooling and it may very well be cheaper because your fuel economy will go down with full e85..So just run 93 and get better fuel economy and similar spark

Rich Yaklin Jr has been through a few lpfp’s attempting to run an aggressive E85 tune if I recall..

I think it depends on your goals? Running E85 just to get to the same power levels you can get on straight 93 isn’t worth it to me. The idea behind E85 is to use its native cooling properties to run more load without knock than you can with 93. AKA cheap race fuel.

Yeah the octane is race fuel like maybe even the same as some....Not sure why he would've gone through low pressure fuel pumps? He did have an older SHO..The pump is made to handle it.

I would say there are pros and cons. You could maybe make more power than 93 oct on less boost which would make life on the turbos easier..Low fuel mileage is a con. Fomos car was probably making meth levels of power according to spark and boost on his E85 tune.

Good discussion!

We are fortunate to live in states where good 93 is plentiful.  People living in AZ, CA and CO maybe more states are irrevocably stuck.  So the more clarity we can get on E85, the better.

 

[bpd1151]

All correct SBS.

RY did have issues with the LPFP. As well as injectors being able to keep as well.

As have an isolated few others attempting to run the full E85 route.

I will continue personally keeping you updated on what my vendor comes up, if anything, on their end, for resolution/upgrading of the LPFP you previously sent me.

I am currently tuning with AJP right now on Full E85. I have a Sheetz less than a mile from my house. It is $1.99 a gallon right now. I dont need a race tune. Just a drive around town tune as I do not commute. My first impressions on the highway is this tune should do around 20mpg at 70mph. Around town. 15ish. Will still save $$ considering the cost of 93oct in my area. I am not going to run this all year as I have 93 and E30 tunes from AJP. This is just a we can do it and have fun with it and it gives the SHO some versatility as far as fueling goes.

Can you give us a quick description of your fuel system set up?
