510km? How many litres did the car take Paul? 50L?

I didnt pay attention man,but im gunna take a wild guess and say there was still about 3-4 L of 98 ULP in my fuel tank so this fuel tank i will let you kno my KM's since there shouldnt be any 98ulp left

Been running E85 in the Evo now for a few months; I'm no expert but my feedback below:

Fuel Consumption - on 98 was averaging 350km before the low fuel light came on, on E85 comes on around 250ish

Installation/Tune - All I needed was injectors - $450ish for 1100cc High Z injectors. Could have gone with $350 ones that would have done the job. Tune cost $1300 for a dual map tune so can switch between 98 and E85, in hindsight should have just got an E85 tune for $600 or so. Was paying around $1.50-$1.60/L for 98, now paying around $1.20-$1.25 for E85.

Availability - enough servos in Sydney that sell E85, and it will grow.

Cold Start - no issues. As the BYP boys said, just tune your cranking fuel table and it will start first time every time.

Temps - don't have a gauge but confident I can do constant laps at the track and not have to worry about engine temps getting ridiculously high.

Power - by far the best mod done to the car done so far. Stock - 160kw, intake and exhaust plus boost control and tune - 200kw, E85 - well over 250kw. A 250kw car on E85 feels much stronger than a 250kw car on 98, the shove in the back is unreal. Ask anyone who has driven or had a ride in my car and they will tell you its plenty fast. I don't see the need for any more power at this stage, very happy so far.

Might i add im happy to see peoples opinions about E85,good or bad,its a good read

used my first tank of United 100 Octaine ULP and got 610km outta 47 litres.
So worked it out via the net's conversion calculator.
Consumption in Litres per 100 Kilometres: 7.7L
Consumption in Kilometres per Litre: 12.99km

Very impressed... Will see if this continues...
On my second tank now, will see how it goes again..
Very happy considering 100 Octaine ULP at Untied is the same price as 98 BP Ultimate.

[l__i__l]

united "100" is just 98 boosted with ethanol

mileage was good performance was par

[MYDC5R]

^^ Already knew that.
Mileage im happy with
Performance wise, felt better actually then BP ultimate but could just be me...
Need dynos to prove this

[Pizzo321]

second tank with E85

450km and i had 5L stil left in the tank

[wpg81]

How much additional timing did u guys set above a petrol tune?(a rough over all figure). Did u tune using exhaust temps or wideband o2 sensor and what type of reading were u aiming for?

Fuel numbers still look good!

[benson]

2-4 deg extra

Not being smart ass bro or anything...
You went E85 with no internal work? Just bolt-ons?
May i ask.. Why? I don't see the need for it :|

Even after when my motor gets built next year, i'll be getting it tuned to 100 Octaine (Pump Fuel), I'd never go E85

I understand that, but this is your daily is it not?
What's the need for E85 like seriously? (Im not having a go or being smart or anything)
Where the hell do you even get E85 from considering not everyone stocks it?

New motor hasn't been fully discussed.
100RON is easily attained in Victoria now and i believe BP is in the works to produce it.

As i said above, full details haven't been discussed but even if SUGGESTED i will refuse to go upon E85, 98/100 RON only.
Why would i go on something that isn't readily available to me for one?
I understand E85 is the cleaner fuel but i don't believe in it's benefits.
Details of my motor build will be kept with me until final details are done and dusted and by the way, i won't be using the K24 that you guys so recommend to everyone.

I've heard enough stories of car thats go on E85 that have engine problems down the line.

But HEY, i ain't a tuner nor a engine builder.
I'll take his advice on board but i'll stand by 100RON over E85

this is watajk off ozhonda..... nuff said LOL.


Benny/anyone, what kind of gains would you see when using supercharged k series? i can image the gains would be amplified being F/I, say your running 230kw atw's on 98, what kind of numbers could you expect with service station grade e85?

[DC245R]

At least 30-40kw from experience with F/I
Although my fuel economy was shithouse lol

Thats some decent numbers.


Any figures for fuel consumption? I know it burns alot faster but im guessing the cheaper prices at the bowser would offset that a little ($ vs kilometres wise).
