E85 vs THE REST! - Page 6

**SSD-85** · 10-03-2012, 09:48 PM

Ive been flicking through this thread & I seem to be getting the impression that E85 has a longer storage life than "normal" petrol. Would I be correct in saying this?

What about this? Tolunene mix at 25% tolunene and 75% BP 98 Test. Calculated octane RON is 104

Anyone tested this stuff and is safe or just a myth?

seriously, just get E85, you're going to do your head in thinking about fuel mixes. toluene was big back 10 years ago, back when AVGas was the fuel of choice as well

not only will E85 produce better results, it's cheaper, higher RON (108) and has many more benefits which far outweigh the use of a Toluene/BP98 mix.

Happens when you start racing at 34 years old lots to learn and catch up on. Cheers big ears.

i was the same, get as much knowledge as you can and try and think of different things. but, sometimes the easiest simplest answer is the best. thinking too much not only does your head in but makes you second guess yourself.

i was always told to race with my wallet (what i can afford) i think the saying can go to brains also, race with what you know, E85 is proven, you start playing around with things you don't know etc, it can start costing you

just wish they'd change the damn laws so I can grow my own

Buttnekid · 13-03-2012, 06:36 PM

ig only old Wait Awhile would catch on, we still cant get the damn stuff without paying $3 a litre

Tell me about it
The minute its at the bowser im switching over to it

prasac · 14-03-2012, 09:13 AM

last time we filled the drum up at United, it had gone from $1.16 to a $1.35

we got a few barrels of E98 for cheap, we are going to have a play around with E98 it's a little harder to start the car with, but, the benefits far outweigh the bad.

after we have a few hitouts thinking bout doing a 30psi E98 tune on our drag car, just to see how far we can take it. no intercooler just straight E98, same as you would do with methanol.

Giant · 14-03-2012, 01:32 PM

Maybe you could use a small second tank with E85 to start the car then switch to the main tank running E98.

I would go straight to E85 just a matter of money for the injectors and tune and fuel pump upgrade. Also sucks that the xCal doesnt let me adjust the tune myself if its winter or summer blend etc.

even in Winter the E85 is pretty bad to start, we spray a bit of 'start ya bastard' in the charge pipe or in the turbo's and she cranks over straight away.

we used to spray it directly into the manifold, had a backfire and the thing bent the throttle body a lil bit. all good now, you need to make sure you have a good throttle body like this one, might be a bit hard to see in this pic

Giant · 14-03-2012, 04:38 PM

Just ordered a pair.... I like the grease nipples

Giant · 15-03-2012, 06:08 PM

I made my own 10% blend with 98 octane works good. How far can I push the stock setup I recon 20% would pretty much max out the injectors with the current NA regulator.

Yeah I know just go E85 I will I will.

not sure on yours, i think we worked out 30% on my Aurion we would start running lean and out of injector. bad thing is you can't get into the ECU and have a fiddle.

love to throw a couple of turbo's on my Aurion and run it on E85, i was reading about a TT 2GR-FE engine in a buggy producing 600kw@18psi that is ridiculous, 485kw@10psi in race trim

those are engine figures.

graham_h · 14-04-2012, 05:33 PM

In case anyone is interested E85 is available at United Warwick

prasac · 17-04-2012, 02:08 PM

United @ Drummoyne and Dee Why also have E85 now.

FreddyDUZ747 · 17-04-2012, 02:32 PM

Found a place in Adelaide(Scotchers)that sells the V8 Supercar fuel for $2 a litre from a bowser,located in Wingfield.

xr6t_ute · 22-04-2012, 11:50 PM

I have tried E98 on my Ba,xr6t ute, and found that it coughed and spluttered through the whole rev range on the dyno, lambda was 0.74 and even, tried pulling the gaps down on the plugs and still did it...so canned the idea and went back to E85.
I can only put it to not enough spark on the std system, whats your thoughts?

how much boost and what were the plugs gapped at? what plug/heat range are you running? did you try leaning it out a bit? if you were getting 0.74 Lambda that is around 10.8 AFR, that is very fat. try leaning it out to around 0.83 (12.2 AFR) depending on how much boost you are pumping in, the spark should be fine if it's not too fat. i think it was a bit too rich.

xr6t_ute · 23-04-2012, 03:21 PM

Sorry typo... Meant 0.84 lambda, and plugs were ngk iridium 7's gapped at 0.76 and we slowly went down to 0.6 and the same thing was happening... I just thought the factory Ba coils weren't providing a strong enough spark to burn e98.

Giant · 23-04-2012, 03:39 PM

Where you tunning with SCT or VCM Suite, where you adjusting the spark dwell etc. Also you may be better off with copper or silver plugs.

You could also look into KB boost-a-spark.

FreddyDUZ747 · 23-04-2012, 05:03 PM

Did you throw a fresh set of coils on her mate?

Im at 1.1 gap with 16psi with the boost'a'spark.

Are you sure your using 1.1 gap at that boost...., everyone on modded Ba Bf's etc are running between 0.8 - 0.7 due to blowing out the spark.

BTW,im not everyone

I also run a single 3" exhaust and less than 3" intake.......shhhhh,dont tell anyone it works

prasac · 23-04-2012, 05:07 PM

E98 is harder to ignite then E85 for instance. but, it should be able to cope i have seen them running more boost on other XR6T's using standard ignition setup.. the copper plugs should ignite better than the iridium.

it's a big gap, we are down around 20-thou, im not familiar with what the BA's like, maybe try asking in the FPV XR6 etc secton what the other guys are running. with the Hyundai/M&W coils with just the igniter we could run E90 up to 27psi, however, this was a different engine. get a hold of some -8 NGK Coppers and have a go. dwell can/will make a big difference, if he changed the dwell and it doesn't have enough time to charge the coil then it won't be a big spark. i have seen it with the LS guys, the LS1 coils take 5ms to fully charge, anything under 2.5ms and spark would blow out at higher boost.

Thanks again... will try those things and see how it goes on the dyno...will also speak to my tuner and find out about dwell adjustment using SCT.
Cheers.

I found the BF coils are better.

FreddyDUZ747 · 23-04-2012, 05:38 PM

I find mine are better than all of them lol!

Sure am running 1.1 gap,I have my own std modified coils and the ignition booster upgrade.I recon I can go wider on the gap again but ill risk frying my coils I recon if I turn the wick up on the controller

Cheapo plugs to FTMFW

we kept the same spark plug gap even after adding the CDI, even though it is producing such a big spark. i think alot of people have a tendency to open the plug gap when they add a CDI or boost-a-spark. we have found it didn't necessarily work, which is why we stayed at the same gap, though we are also pumping in a little more boost.
