A HAA just got the news!!
Hi Joshua
 
North Adelaide is live and selling Bio E-Flex. It became available a couple of weeks ago. :)

Yea stock HG. I've got maybe 60% of what I need for a rebuild anyway...just need to source cams/gears, crank, sump and have some headwork done and bore the block out to suit the pistons. All in time though.

doing a bunch of work on my car still......waiting on my inlet manifold to come back then i can get onto finishing it. Considering getting some good teflon hose for all fuel lines and see how the walbro copes with E85 straight, if it dies then one of the aeromotive pumps which are E85 safe. Running aftermarket ems and 850cc delphi injectors, i should look up how much i can flow with 850cc injectors on E85. Figure if i have the chance atm to get the car ready for E85 so i can use it at some point (dual tunes) i may as well do it, but there isnt much to it on our cars is there? Just pump and the rubber lines (debatable, but safe than sorry right?), injectors and thats about it other than typical supporting stuff.

Some more food for thought.
 
One thing that is rarely discussed in regards to e85 is fuel temp. Your mixtures can vary up to 15%, based on the temp of your fuel. V8 supercars run a fuel temp correction on their tune, to allow for this.
 
For most, this would not come into much of an effect, but when you start getting into higher power figures, and particularily if you start pushing closer to the limits of the fuel, it is a wise thing to consider.

Good point if your planning on running full E85. To have some correction on an older standalone you'd have to add a fuel temp sensor and add a bit of circuitry to the IAT input maybe.
 
We really need to look at this whole E concept from two perspectives..
Stock ECU's running mixes for power gains, and
Standalones running 100% E85 for track use.. there's a large gap between the two.

I might take a tiki tour tonight down to Marsden and fill up on some E85. Ive got just under half a tank so I'll fill up just past 3/4 with 98 and then the rest on e85. Will report back my findings. I'll have a towtruck on standby.

Hahaha!  James,
is that in case the engine blows..or the car slides into the nearest power pole with all that boost lol.

In case the engine blows :D I'm keen to test out these engine mounts. I've always had dramas getting into 4th from the top of 3rd :P

Well what can I say....I'm going to invest in a drum of this stuff I think. Filled up with 98 which only went up to just over halfway. Put 6L of E85 in and drove around for a bit. No difference in idle or around town performance/driveability. Came along Wembley Rd and ripped it. Felt good but wasn't overly impressed. So went to the M1 and launched it in 2nd on the onramp - boosted to 17psi!! Was picking up speed that quick that by the time I had snatched 3rd the speedo was still rising while I wasn't accelerating. 3rd pulls very hard and very smooth. Powerband still dropped off quite sharply around 6-6.5k but I think that may be attributed to not enough fuel being supplied which I should be wary of with lean AFR's and that much boost.
Very impressed though and definitely wanting to experiment further with this bioflex stuff.

NO!!!!!!!!!!!!!!!!
 
No!!!!!!!!!!!!!!!!!!!!!!!!!!
 
did I mention NO
 
E85 is a crock per liter it has less energy than 90%+ petrol it is unsustainable and its bull ****. you would have to replace the entire fuel system as the ethanol will eat seals and gaskets.
 
octane is higher so what? octane is a measure of detonation not of power. 
 
this is snake oil really bad no, no, no!

petersweeet, read the thread before posting such ill-informed drivel.

jdmr288 - Powerband still dropped off quite sharply around 6-6.5k
 
James, I think you might be hitting the limit of the gen2 ECU/AFM, the main reason why you can't push past 270hp with this stock setup, without some form of tuning. The other side of the coin is that at 20%+ or so, the stock 440's are only going to be able to support around that level. A safer option to go further would probably be 550's and a fuel/ign controller like the ECU3 with the MAP sensor.
Also, if your still running an un-modified rail & tired pump, pushing the power band higher would be marginal at best.

petersweeet - your obviously not a drinker -:)
My momma once said "cars and alcohol don't mix" - how wrong she was.
 
The whole concept of this splash blending E on stock ECU's is to maintain as high a level of ULP98 (higher energy-smaller volume) as possible, while adding sufficient E to sustain the JDM ignition timing, and provide the other benefits of E, as possible..all within acceptable AFR levels.
On a standalone or stock ECU with a fuel/Ign controller, you can re-tune to accomodate larger injectors and as high a level of E as practible, tho there are limits where gains will decline, or injector sizing becomes an issue.
The power gains involved come from several directions (as discussed already) but by far the biggest is optimised Ign advance due to the properties of the added E.
