Joeyjoejoe's E85 Tuning Adventutres

[joeyjoejoejuniorshabadoo]

to be honest this kinda worries me....

i'm running 300+rwkw on standard internals and hence cant really afford any inconsistencies in my fuel... as with many of us here.

i'm happy to use minaldra/powerplus as i am of the opinion that their qulaity control will be spot on as they are a dedicated race fuel manufacturer.

there are 2 main points that concern me

1) with caltex making their own recycled ethanol from various waste products, what will the quality/consistency be like? on the caltex news section it said they are going to make fuels with up to 85% ethanol.... now this could mean either that the ethanol content is going to be around 85% or simply that they will also be making e10 etc in the same plant. To run a stock v6 commo, there is a fair tolerence in fuels before detonation will occur.

2) i'm worried that people are gonna blow their motors up. for example, say you tune on manildra @ 106 octane, and then throw in some CSR 104 octane and go smashing it around without a hand controller or any knock warning device... its the same as running a 98 tuned skyline on standard 95 octane. with caltex bringing a third fuel to te game, this could further increase chances of this....

at this stage, i'm going to keep using manildra fuels only until i can receive some confirmation on the caltex fuel

I am not a chemist so i cant really go into details, but apparently Ethanol is not a great winter fuel and therefore Caltex will be following worldwide practice by making the winter mix contain more PULP, hence the 70% (winter)-85% (summer) ethanol mix.

I know for a fact that if i run our E85 i will be having 2 tunes, summer and winter.

If i were you i think i would be more concerned at the fact your supplier hasnt given you this information. I guess we all need to see how E85 reacts in winter and go from there.

we've had the car on the rollers through summer and winter, and the only difference has been that it just gets harder to start in winter lol

Geez you worry too much, you could run a 50% mix with all the det protection! I'd like to hear from any tuner who has managed to get this gear to knock at all, there are national standards set if you produce/sell this stuff, there not back yard company's!!!! Lol.

and whats this bagging CSR sh*t, they have made a big investment to produce it here in Oz and I for one am very happy they have.

Where your comparison's done on the same day, same dyno, same air temp, same age batch, was there a big enough percentage difference in power to exclude all these variables? I dont think it's fair to say one's better than the other unless you have done this!

[joeyjoejoejuniorshabadoo]

i'm not saying CSR is shit at all... its a brilliant fuel

i just prefer the manildra stuff

i used 10% less fuel and 5deg less timing to get the same power... (and the same result with daniel's car)

same tuner, same dyno, same weather (roughly), both fuels purchased on the day of tune, but on a different day

its true that it wont knock, and i'm not really worried as such, i just happen to live near the servo and might as well use exactly what the car is tuned for

Has anyone tried warmer plugs for the e85 cold start issue? Would they help?

[joeyjoejoejuniorshabadoo]

nah, i just turn the key more

[N I B]

I agree with the Powerplus, We tried a few different brands with our Race cars and non came close to Powerplus in both IP and Sportsedans

Kingscorps IPRA S14A racecar in round 1 at Wanneroo this season had number 3 Cylinder liner sink letting the gasket blow with massive water loss and over heating the result, The problem was there from qualifying but we needed the points so we decided to go for it and get what points he could, He had old tyres from last year and still won the meeting and set the lap record.

After stripping the engine every part was still in good condition and is now in a fresh block, Im sure the fuel saved the engine.

the reason E85 is capped at 85% is the fact any less than 15% pulp makes the cars a real cop to cold start.

Biobutanol is my latest fixation.

[SS8_Gohan]

really? just had a quick wiki.... about 96 RON, bit more stable in terms of water contamination and less corrosive than ethanol but wouldn't you lose all the goodness of knock properties of the E85?

and doesn't seem like it would make more, or even the same amount of power as E85?

this is just what i gleamed from a quick wiki glance, so could be way off the mark.

[joeyjoejoejuniorshabadoo]

have been running 98 ron since the last DECA and decided to go back to e85 for the drag day...

DAMN i forgot how good this shit is!

[NYTSKY]

I cant remember what ULP feels like

[Trozzle]

CMON BRING THIS SHIT TO CANBERRA!!!!

[180or200]

I cant remember what ULP feels like

I've tuned a few on 98, the guy's say "go's alright hey", I'm like "does it"

I would rather walk than go back, even if it means 150k's less to a tank.

How many kms do you get lol, 150? haha

300k's to 70L at the moment. Going in for another tune at RE tomorrow for more powah.
