I’m tryna get my car to run e85 but don’t know what to do ?! (Please dumb it down a bit since I don’t fully understand cars perfectly yet lol )

 

All you really need is a tune for it. E85 uses about 30% more fuel than pump gas so the entire fuel table needs to be adjusted.

what mods do you have?

 

i have a hahn intake and that’s about it. But I was curious in what upgrades do I need to even be able to get e85 ?

 

To take full advantage you should do at least a 3” down pipe. But it wouldn’t hurt to do the charge piling and intercooler if it’s still stock.
but you could run e85 completely stock as long as you are tuned for it. To take full advantage the mods I listed would be ideal. But you will get gains even with stock piping. Downpipe is the biggest restriction by far.

 

I would get the gms1 3bar map sensors and plug and play harness for when you get tuned as well.

 

dont I also need a fuel lobe as well and a new fuel line ?

 

Really depends how much your pushing for power wise. I’m not sure if the stock turbo can run it out or not. There’s guys on here that could give you more specific info in that regard. You won’t need new fuel lines at all.

 

You also have options of mixing your e85 half and half with highest octane at your pumps. And you get e47. This helps reduce the added volume needed by half. You would always have to mix your fuel though.

 

GM 1 stage sensors
LNF intake camshaft with upgraded fuel lobe
opel HP direct injection fuel injector
LNF high pressure fuel pump upgraded
LNF cobalt fuel filter kit
ALL ZZP
how does that sound ?
i just read more about it on a zzp article and this should make running e85 like a breeze with really good HP/WHP with the tune

 

I also have an upgraded Inter cooler lol but let me know if anything on that list is unnecessary

 

You definitely don’t need all that on a stock turbo. Future considerations not withstanding.
Injectors and bigger pump are for higher power levels. You may need the cam if you max out the stock turbo and let air flow. I don’t know the exact power limit you can run to on e85 before that’s even needed.
the pump and injectors are for guys pushing allot more than k04 power.

stock fuel system on pump gas can get you into the low to mid 400s

my guess is on full e85 it would support at least 330whp.

 

so pretty much just the sensor and the camshaft with the upgraded fuel lobe right ? And then get the rest when I upgrade my turbo

 

I would recommend running a 50/50 mix or E47. The stock HPFP will be a bit low on pressure up top resulting in a higher IPW. With the lobe alone E85 is quite easy on the K04. Either way you will need a tune to run ethanol and you can just get it tuned to a safe level and everything will be just fine.

 

So I can’t really run all e85 ?

 

The stock fuel system will keep up with a straight E85 tune when everything else is basically stock. Once you start flowing more air it falls off quite quickly and can't supply enough.

Unless you're chasing BIG whp, there really is no reason to run straight E85. Most of the guys run E47(50/50) just because it's been proven to get near the same level of power output but with less required from the fuel system.

 

You are at sea level so you'd have to run a somewhat mild tune to keep the rail pressure in the correct window. Our engine loses a lot of efficacy when the rail pressure drops. I could post some logs of the rail drop on the stock fuel system but I don't have my laptop on me.

 

I have tuned LNFs on E47 over 500hp. E47 is great, it's just a bit more work.

 

i just don’t wanna deal with mixing is all did you see All the parts I posted ? Wouldn’t that be good for me to run straight e85 ?

 

So let’s clear it up for him. Km043.
on strait e85 whats the outer limit for power without any fuel mods before rail pressure starts t become a problem?

 

but if I got the high pump fuel pressure wouldn’t that help ?

 

Yes it would. But what are your power goals. May has well not waste money on things your not gonna take advantage of.

 

i can get all the list of parts that I said earlier and then down the future get that upgraded turbo ?

 

Ahh okay so you are planning to upgrade the turbo. Well in that case start with the upgraded fuel lobe cam. You can keep adding other parts as you go and need more fuel. Maybe consider the stage 1 cam upgrade with the lobe since your doing the work anyway. The bigger mechanics pump is easy to add later. Injectors are more involved and probably the last thing to do is your pushing enough power to require that.
really depends what lower level your expecting to get to.

 

can you send a link to the stage 1 cam please ?

 

Or do you think this 91 tune is good ?
