Thinkin about coverting to E-85

[Akai oni]

there's a guy on css.net that did it...

He's running 12.8's @ 110mph with 60# injectors and a tune to run E-85, im unsure about his other mods but he has been running with it for a while now on the stock fuel system... im thinking with a return style system and E-85 the capabilities could be fucking awesome...

There's alot of tuners here offering E-85 conversions and ive seen some insane numbers come out of minimal setups using E-85...

like a local 240SX from denver, guy has an SR20DET swap with bolt on's, MBC and FMIC, running E-85 with a tune and the fucker put down 438whp at this altitude.


opinions?

E85 is supposed to offer better octane and more power from what I have read and heard. Remember, you'll see about a 25% reduction in MPG though.

It may be a cool thing to do versus running 110 race fuel. It'd sure be cheaper.

e85's ~105oct so is a great thing for boosted ppl. only thing to "worry" about is its corrosiveness. tune for it, and don't leave it in your tank for too long, and u'll be golden. I've also heard you need larger injectors for it, probably just because of the systems others are trying to use it with, though. you can find out a ton about it if you search HPT's forums.

I'd rather use homemade octane booster... you can't get E85 where I live.

I thought our cars didn't like additives...

and if the homeade octane boosters out there are safe on the engine...

how do i make it and what kind of mix (i.e. parts of octane booster per parts of fuel) would i need to get 100+ octane out of 91 octane fuel?

sheek used to have some crazy "recipe" for his "sheek sauce"... not sure if he ever did post it, though.

You know what... he told me a while back that if he got it to work correctly he would give me the recipe...

:bananahump:

i gotta email that fucker...

Well i found the Sheek Sauce recipe... nothing too impressive...

all he did was mix 3 gal of premium fuel with a bottle of NOS octane booster, a bottle 104+ octane booster, and a bottle of outlaw octane booster, a couple of moth balls, and some tolulene...

maybe good for 95 octane and extremely expensive to make...

i may just mix some 110 octane race fuel with some premium and do it that way... another thing im thinkin of doing is making a highly concentrated 110 octane + tolulene mix and add it in "doses" to raise the octane rating...

not sure yet...

there was someone on RLF.com that made a post about mixing race fuel with premium and with normal, daily, city driving, was getting over 300 miles to a tank.

Just make sure the race gas you use has no lead. They aren't required to advertise that in some states. The lead will clog the cat. There was someone on there that gave a link to a site that showed how to do the math for simply adding toluene to your fuel. The right amount made the octane go up significantly. No cost savings though in my opinion, unless it raises the mpg more than 2 or 3.

shit i had (maybe still have) a good quart of toluene in my garage :up_to_som:

1 gallon of toulene and a tank of gas is wicked shit...
The old F1 cars used to do that. The only issue is, you can't let it sit like a normal tank of gas, it needs to be used. So, keep the ratio of 1:10 (toulene:gas) and make smaller mixes.
I'll see if I can find the documentation that talks about the old F1 cars and toulene.

yeah Kev (SMP) told me to use a cup to 10 gals, so about a cup to a tank

You can use either Xylene (which is nasty stuff) or Tolouene. Basically, mix a gallon of Tolouene (paint thinner, available at paint stores) which has an octane rating of about 114. Mix it with a few ounces of Marvel Mystery oil and a few ounces of automatic trans fluid (for cleaning and lubrication, respectively). They recommend you can mix it as much as 30% with 93 octane, which will get the overall octane around 100. I found the recipe on a Buick Grand National website, of all places...

actually....this is what I found
Q: Can I just dump in 100% toluene into the tank like the F1 racers?
A: First of all, the F1 racers did not use 100% toluene, but 84%. The other 16% in their brew is n-heptane, which has an octane rating of zero. The reason for this strange combination is because the F1 rocket fuel was limited to the rules to being of 102 RON octane. The n-heptane is "filler" to make the fuel comply with the rules.

Toulene
R+M/2...114
Cost...$4.50/gal
Mixtures with 92 Octane Premium
10%...94.2 Octane
20%...96.4 Octane
30%...98.6 Octane
Notes: Common ingredient in Octane Boosters in a can. 12-16 ounces will only raise octane 2-3 *points*, i.e. from 92 to 92.3. Often costs $3-5 for 12-16 ounces, when it can be purchased for less than $5/gal at chemical supply houses or paint stores.

Ok... now is our gas tank a 12 gallon or 13 gallon tank, i keep forgetting, lol...

so for 12 gallons i would need to add 3.6 gallons of tolulene...

for 13 gallons i would need to add 3.9 gallons of tolulene...

for 98.6 octane... so... 8.4 gallons of premium fuel and 3.6 gallons of tolulene for a 12 gallon tank and 8.1 gallons of premuim fuel and 3.9 gallons of tolulene for a 13 gallon tank...

correct?

[EDIT] did a google search for tank capacity... WOW, the 04-05 redline has a 13.5 gallon tank and the 06-07 redline has a 13.0 gallon tank [EDIT]

[Doc]

sounds right :lol:

[Cat Ion]

Cost effective for racing=yes
cost effective for DD=hellz no!

[aikidoshadow]

Well with gas prices it really isnt much of a difference now.
$4.05 gal 91 is highest I can get
$4.50 gal tolulene
In about three months it wont be any different for me.

[RL_Clark]

I don't see it being much of a difference at all now. I paid $4.23/gal for good old fashioned Shell gas yesterday.

Shell gas used to make my car run like a champ but as of late thier gase acctualy makes me lose power... it's quite noticeable too...

one of my buddies said that it was because as gas sits it loses its octane rating and due to the high prices nobody is buying premium fuel... but when i put in sinclair or diamons shamrock gas the car runs like a fuckin champ...
