E85 fuel

[Celica RA45]

just did some dyno work with E85 fuel from united in hopper crossing as they are the only bowser in melbourne that sells it .have been using the 100 united since the shell V power got the flick
any way what i did was do a dyno run with the 100 check all the settings and check oil temp etc and then shut it down turned off tank pump and set up the out side jerry can and bosch fuel pump to connect to the fuel filter and fuel return back from the reg
checked lambda and do a few power runs
on my 3sge it has 13.5 to 1 and about 28ign timming for wot
any way what i started with was 84 lambda and for best power was 86 lambda then started to play with timming from 28 and add 1 and then 2 and last was 4 degress
any way with the stuffing around i have gained 1.2 kws at the top end and picked up 2 in the mid range and with the std timming of 28 degress
was told by a lot of people that i should get 10% increase in power and 30 % in torque
well what a waste of time and fuel to only get this much


And for you edd oates i dont think you will get as much power increase as you think you will just stay with what you have ,you will be better off unless you go up to 15to 1 comp then it might be worth it

Different story for boosted engines Glenn. Local shop has seen around 40rwkw gains at same boost....pretty common to read about this sort of gain in tuning articles in mags.

Det resistance was unbelievable....on an Evo it wouldn't det with more ign adv up to and beyond peak torque.

It would be interesting to hear the inside goss on what the V8 supertaxi's think of the stuff?

Most teams now quote power figures of 640hp where they used to claim only 620hp. Could be the fuel but this is just wild speculation.

im really keen to run this fuel as im mucking round with an na+t project at the moment.
havent been able to find it at any gas stations in brisbane so will have to buy it buy the drum.
did you put more fuel in as im pretty sure you need to run around 30% more to get the right afr's with this fuel.

[white_sandshoe]

From what I understand about E85 is you're getting your 30% more power from running 30% more fuel... But to get the benefits you,ve gotta dial in advanced ignition because of the different burn characteristics.
It's a slow burning fuel, so you've gotta wind the timing right out. I've heard as much as 14 degree over standard, but i'm yet to confirm that.

my uncle is runnin e85 in hes 200sx on pump fuel he was making 280kws and 302kws with nos .now that he is running e85 he had to go twice as big for hes fuel system 1/2lines
1000hp fuel pump 1000cc inj and they are still maxing out now hes make 350kws on e85 with only 25psi .now hes going to runn 1600cc inj and tuner sayed will make over 370kws easy .its a good system to lookin to
e85 run's cooler temps,brings the octance levels up to 110-115
he only gets 200k's a tank but it only 99cents a litre

i have been looking into the e85 fuel as well not many places sell it but i have heard great results with turbo cars as there inlet manifold are staying alot cooler with the e85

hes a site worth having a read

Unless you have full control over the ECU and plan the engine based around the idea of E85, it's pointless. Both FI and NA cars can run more compression and more timing, leading to more efficiency and power. Yes, it does use more fuel but it's also expected to be a fair bit cheaper (when it's easily available) so costs end up roughly the same.
I'm planning on a blown 4AGE, aiming for 20psi of boost and 9.5:1 compression. As long as I can keep fuel up and get the tuning right there should be absolutely no issues with detonation at all.

i have a map ecu to run with the 1ggte ecu and apexi sitc on my 1gge should be able to tune it ok it also runs 9.5:1 doubt my dodgy turbo will run 20psi tho was guna put some 7mgte 440'cc injector's in.
the only thing ive heard aboout buying it up here is buy the barrel 205 ltr for around $450-500

[the_random_hero]

As far as I know you need a fuel logbook to purchase it too, only for racing purposes. Have contacted a few major suppliers, they said that it is coming to QLD but don't know when.
Last thing I read was around $1/L and it won't be greatly affected by price of oil. It will all come to supply and demand - heaps of people start using it, then it will be cheap as chips.

u wont have issues with detonation at all its very hard yes i mean very hard to get detonation on e85

[Celica RA45]

my motor makes peak power with 28 degress of timming ,on ELF lms we can go up to 32 and make another 7 kws ,but with this with the extra fuel and trying to go up in timming was a waste of time at 32 we lost power but the motor wasnt pinging .it just goes to show that this motor is at its peak effientcy

[white_sandshoe]

Yeah... Time to bump the compression or some light forced induction. Maybe pump in a couple of pounds and see how she goes then.
I'm guessing there's not a huge benefit running E85 on a standard engine. By the sounds of it, E85 is best used to open up an engine to mods that were previously impossible or impractical.
Extra high boost and compression and the like...

I'm curious to know if anyone has seen any benefit using E85 as a 'buffer' so to speak for boosting a N/A engine...

Due to the slow burn characteristic, spreading the power over the detonation stroke I like to imagine that it'd be safer to run something like 6-7 psi on a N/A engine...

You're pretty much right there white sandshoe. People must first understand what higher octane numbers do to understand why a higher octane fuel can be better. A higher octane rating means the fuel has better resistance to pinging, which means you can run a higher compression ratio/more boost/more timing, which is where you get the extra power.

The fuel itself does not give you more power (unless it has a greater energy density, which ethanol does not), thus running E85 on a stock engine wont give you any more power than 98 octane as that is as far as any stock engine is tuned for in australia. if you want to see more benefits you NEED to adjust your engine to suit, with more boost, higher compression, more aggressive timing, and with a tune to suit as well.

also, this has been discussed in depth in general car chat before

edit; sucks to hear you didnt get good gains with your engine there celica ra45. sounds like you are gonna need higher comp pistons if you want the full benefits of E85.

or boost

pfft 6-7psi on n/a ghey I ran 17psi with 10:1 comp no issues With E85 and 11.5:1 comp ratio i'll be aiming to run around 12psi
