whats it take to change a TD to E85?

Thought there was a thread on this before but I couldnt find it. Want to do this in my charger

Bigger injectors and a cal..

Bigger injectors and a cal..

I don't know that I would leave it at that. Most of our fuel systems would not be very happy with the alky running through them in that high a concentration these days.

Anything Al should be anodized, and you really should use SS for everything else. I know that Ethanol isn't anywhere near as bad as Methanol, but it still isn't the most friendly thing in the world.

IIRC I had a pretty decent alky thread on here a while back.

this maybe helpful

I got a brand new tank, walbro 255, brand new +20, new fue injection line, and new fuel lines the whole way. So all I need is the cal right?

You'll need much larger injectors. I believe the FFVs ran something near +20s stock. I've done calculations and come up with 95lb. injectors for near 400HP if memory serves me right.

There is another thread which is very recent where a guy was suggesting 160lb injectors based on his experience running E85 in a boosted vehicle.

Not a fan of the E85 fad... but if you must, get a FFV rail and injectors as the SS will hold up better. If you want more than stock boost, like Cordes said you will need bigger injectors... yes the stock FFV injectors flow close to the +20%ers

I think you'll need more than +20s just to accommodate the added fuel need when running the E85. The FFV cars had +20s to meet the fuel demands of the NA cars...

I do agree that a FFV rail would probably be the best cheap way to go.

[BadAssPerformance]

It all depends on how stock or modified he wants to go. I think they would be OK for a stock setup, but dont take my word for it, never looked into using that garbage

From my research a couple of years ago, +20s will be a little small for even stock boost levels. Any mods at all and they won't be enough. This is all on paper of course.

What does your paper say about +20%ers running 27psi thru a stock Garrett, stock IC, etc on 100 unleaded?

You think e85 is a fad? The ---- is great, it isn't some silly thing. It does it job, ask your boy Clark.

160 seem a bit much unless maybe you have a really high horse power car and you don't have your FPR vacuum line hooked up.

If you take 72lbs@43.5psi and bump them up to 80psi they become 97.6lbs injectors. That is a ton of fuel.

Meth needs 50% more fuel then gasoline, where e85 is 30%.

This is why you use the back of an envelope, a clean sheet of paper is a n00b, an envelope has been around a bit.

Never said it couldn't be used or make power.

The fad comment is cuz many think its a magical replacement and better than for race gas. Group of people all liking the same idea = fad, good or bad.

I'm presonally not a fan... the 85% is inconsistant and uncontrolled unless you buy it from the same vendor or in a can. Also, if you do the work to make a fuel system safe to run alcohol, why not just run meth?

But this thread is not about my opinion, so back on topic...

How long does it take a Walbro to fail from E85?

You think e85 is going to go away after awhile? I define a fad as something that is silly and goes away after awhile. You says that same thing about any pump gas (yeah yeah race gas comes from a pump) but what I find funny you don't worry about inconsistent and uncontrolled track conditions. If you a running on the ragged edge of your tune then track conditions are going to require the same changes. I am not sure how much better it is the race gas but people are seeing really good numbers when putting e85 next to race gas and it is a hell of a lot cheaper. IndyCar is now running on e85 if that says anything. Next it 93 octane it is a lot better. How long does it take a Walbro to fail from gasoline? The one is my SRT is getting loud as hell and it doesn't have much use with gasoline only.

If the car is close to bone stock I bet it would be fine. I was surprised at how much boost Clay was running in his omni with +20s at Palooza one year, but when he stated how little had been done to the car mod wise it made sense.

I agree that 160lbs injectors seems way high. Another member of the site went to them after 95s wouldn't cut it though. Granted it was for a different application, but I felt a comparison could be made.

For stoichiometric E85 will need 30% more fuel. I've read that alky likes to be run richer than gas by comparison and that one shouldn't shoot for that 30% number when doing calculations for a performance application.

I've read that they will fail if you leave them sitting in the alky for too long with out running them. It does seem like guys get a very long life out of them with regular use though.

If the subsidies dry up, E85 will be a thing of the past over night. There isn't any money in the stuff without the government propping it up. If I'm not mistaken racing bodies which are going to it are doing so due to sponsorship from corn/ethanol producers...

[OmniLuvr]

well, here in sunny so cal, there talking about making leaded race gas illegal, everywhere! so they cant sell it, and we wont be able to run it at the track anymore.

plus e85 wont destroy your o2 sensors after running it for a full tank.

there is also talk that the extra volume of fuel being expelled from the exhaust will help to spool turbo's quicker.

my friend has been running e85 in his n/a Z06 for three years with no problems to his fuel pump, and he made 42 more hp on his e85 tune as compaired to his race gas/pump gas blend. but we dont have 93 oct out here, just 91...

and i also dont think they "have" to make it out of corn, just anything they can make sugars with to create the alky (but the corn is very plentifull), they are trying to make it out of scrap wood pulp that is left over after making paper using special selected bacteria.

so why dont you like e85 then JT?

Fads are not always silly, but yeah they go away. If E85 was so great why aren't there more places that sell it?

Huh? Uncontrolled fuel is a tad more dangerous that a crappy track.

True story.

Inconsistancy of product - Unless you buy it in a can it is highly doubtful it is close to 85%

It may cost less but you have to run more of it to make it work

It is corrosive to all fuel components

I have multiple gas stations with race gas closer to my house than any I know of that sell E85


Now don't get me wrong, I like ethanol, but I prefer it with a slice of lime or a few Olives swimming in it Oh look at the time, its half past beer thirty.. later gents

[shackwrrr]

Its a common misconception that E85 is corrosive, It's not. E85 is hydrophilic meaning that it adsorbs water, the water is what rusts everything out. So if you are using it as a race fuel and wont be leaving it in the tank for extended periods then there are no issues with the steel in the system. Now it is bad for rubber in the system that may be old, but if you have new rubber lines then there should be no problem since most fuel line is alky resistant.
