Hey folks, just wondering how many members are using E85 in their rides? Ive just had my car tuned (no conversion bul**** needed if you are using an aftermarket ecu) with this fuel. I gained 20rwkw using it & its amazing the topend difference it gave. At the moment its not that readily available, but Im guessing (& hoping) that the fact the V8's are using it as their designate fuel in 09..that a few more independent chains are coming on board. At present...my GTS has 210rw on just 12 psi... gotta get an EBC to stop the spiking to really benefit any higher boost adjustment. Come on people...its 110ron & a great performance fuel..the more it gets used the more available it will become.At present I get it for 99c/L...which is expected to drop to around the high 80's due to petrols drop. Chek out the U tube videos & docos on this stuff...the E85 supra in particular is an animal. PS...oh & its emissions are FAR less than unleaded. Cheers Dan

yeh upto betweem 50% and 70% less the co2 emmissions, not that that's its greatest selling point.. I mean it is good, for the environment, but has a few other pros about it too... Im keen to get on it.. but I dont think its as easy as just saying 'come on guys more ppl use it the more it'll be available' Up here there is not a single pump where we can get it from, yet. There was supposed to be one available at a United Servo in Virginia, its installation and flow was supposed to coincide with the launch of some new saab range of cars that can run solely on the **** and take full advantage of it, but due to local council and other legal delays, has been put off indefinately... From what I have read there seems to be a bit of a delay/war going on to see who will act first kind of thing.. its all money related.. but the manufacturers kind of need to produce more cars that can run on it safely, but at the same time are hesitant to invest so much money when the fuel companies have not yet got in place the pumps to support it.. I guess it goes both ways, u need to have the fuel before u can make the cars, but then u need to prove u can make the cars before they'll put the pumps in everywhere.. either way i hope they ***ing sort their **** out, cause I will be following ur lead and getting some tuning done on it aswell to test it out... The V8's as u said are 'going green' and they look to have already done alot of testing with it, with much results... With its more widespread use in v8 supercars, where they can use the media exposure to educated the public about the fuel they will be able to get a bit of support behind it. Not only that but Holden will or are already looking at soon producing commodores which are E85 capable.... Sydney and Melbourne leading the way.. QLD is behind with almost everything lol.... but at least when we get the pumps here and its all go, the refinery will be only around the corner almost...

its octane can vary from like 108-112ish, depending on what they make it from (corn and wheat or whatever they use give diff octanes, make sure you get it tuned to the sh*t one) yes its cheaper, but you use a fair bit more, so overall running costs would be similar i rkn. let us know though

E85 has been at the pump for ages at the local ethanol service station down here. Very true that it has high octane and reduces emissions into the environment. Ideally you need to run aftermarket ECU and upgraded fuel system to take full advantage of this fuel as you need to push more fuel into the engine for a given horsepower very similar to methanol. I think the near future is going to get very interesting with this fuel available at the pump. Once it gets know and tuners start using it we will see some cars running the streets that would normally have stated that this is my race tune etc C16 fuels and the like. Overall very excited to see some results from RB30's on E85 I have been half tempted myself. see how we go.

E85 as far as I know is made purely from sugar cane..well thats the CSR stuff anyway... & its a constant 110 ron from what the guys at Just engine management (my tuners) have informed me...as theyre in constant liasons with CSR. As for the fuel system upgrade...not at all!! My pump, lines & injector rail are all as before. The fact I had 550cc injectors meant I didnt have to change them either...but yes..if you want to make decent power...the standard VLT ones would be destined for the bin.

stoich for e85 is around 9.6:1 whereas ULP is around 12.7:1 this equates to around 30% more fuel required to reach effective comparable mixtures. 30% more fuel demand will indeed require some people to upgrade inj/pumps etc but IMO it would be well worth it. the amount of energy per gram of fuel is less than ulp but when conciding you're using 30% more you can see why sipposr31 got a hp increase straight off the bat. From what i have read NA engines do not seem to respond nearly as well turbocharged engines, perhaps this was the article on V8SC's using it as they're capped at a certain CR, and im sure they're already running over 30deg of timing so there wont be a great benefit there, but turbocharged cars will have the benefit of the cooling effect that comes with fuels that run far richer. Ive been meaning to give it a go for while now, but not only will i need injectors but also a 3 bar map sensor. hopefully turn my 500rwhp into 600 with applicable boost increases. Some original photos have not been recovered yet.

I noticed on the weekend driving down to kiama there was an enhance servo in Albion Park Rail...do you know if they carry it?? be good to know I could do a drive down South safely.

Quote: Originally Posted by R34NRG stoich is 14.7 for ulp. although most people still say you'll only use ~30% more Right you are. should have proof read that.. I think the difference comes with the tune, us with turbo charged cars on ULP would never tune for 14.7, i know i tune for 11.5:1, perhaps you can tune for 9.6 on the dot with e85 and not encounter issues with det. Some original photos have not been recovered yet.

im definitely going this route to acheive a much safer,beefier pump fuel tune.Cant wait to see how it goes.

Have a look at some of jetR31 posts. Darren was on to the benefits of E85 early. Also dynowog has been testing and tuning E85 for a while as well. Anybody know how many E85 pumps in Melb so far?

Anybody know if there is anything internally to the motor required to set a car up for E85. I am currently screwing an engine together and wondering if rings set up would need to be different to ULP set ups. piston changes etc. anybody wish to share their experiences would be great. cheers

More static comp won't go astray though.

Does anybody know if there are any problems running a std VL fuel tank when running E85. will it corrode etc? just setting up my fuel system with plans to eventually run E85 once engine run in.

I do belive this stuff may degrade old rubber hoses.
