So I have been researching "el cheapo" fuel options, and have been debating between 25% tolulene mix with 93 octane, 25% xylene mix with 93 octane, or simply using 100LL aviation fuel (all three options are around 100 octane). Tolulene and Xylene are $16\gallon, bringing a total of 4 gallons of mixed fuel to about $27 or $6.50/gallon, which is still cheaper than sunoco 100 unleaded at $8. Aviation fuel is 4.23\gallon, but obviously limits my refueling options, which I can still live with. My question is, is there a way to run a 50\50 mix of xylene or tolulene in my water\meth kit instead of the meth, this way i can have the benefits of higher octane in boost while not wasting it on normal driving, also it will bypass the fuel system which it is supposed to be so rough on. Any insight? Thanks!!

 

While this will work, the problem with those 2 chems in pure form can attract the eyes of the DEA, since they can be used to make drugs in some fasion.

I'd stick to h2o/meth or straight meth injection, since it adds not just burnable fuel but also oxygen. It also cools the intake air charge, which is another benifit. I know a friend that bought a 55gal drum of pure meth for his Evo, which was making ~45x WHP with a stock setup, other than the turbo being clipped.

LOL, Toluene and Xylene are painting thinners.. You can get them from any paint shop.

I'd go with toluene, thats the most common component in octane boosters.

True, but here in the states if you're buying a lot of it they think you're making drugs

I'm with HiProfile, I would stick to basic meth injection instead of messing with fuel mixtures.

 

you want toluene, xylene contains other lubricants that you dont need.

 

so what about 1/3 water 1/3 tolulene and 1/3 meth? are they dangerous to mix? is that **** going to eat up the holding tank or the pump?

Or any opinions on the 100LL aviation fuel?

 

just pay the 8$/gal for the 100 unleaded at sunoco and be glad you can.. nothing like that around here, i would kill for that, or E85.

 

8/gal for 100 unleaded pump around my place would a damn rip off. might as well go with meth/water injection, a knowledge of tuning, and be on your merry way.

 

I have meth injection right now, but it is an h22 at nearly 11:1 cr on just under 11psi, it has a great tune and it putting out 366whp, but was doing 379 at just over 12psi, the car was fun, but it had a tiny bit of audible knock so i pulled the boost back a hair. I really want to make some kind of 4xx number on this setup, but im going to need some help. again, currently it is 93 octane and 50\50 h2o meth, I was thinking of doing a 3:1 tolulene mix directly in the fuel tank on top of the meth injection, but that is going to cost alot...

 

trick 114 -= 6.35 /GALLON... wITH THE XYLENE/TOULENE... dONT RUN MORE THAN 25-30 %.

 

1: Toluene and/or Xylene do not mix with water. They mix with organics that are hydrophobic, such as the gas. So if you did any mixture of water and x, make sure they are miscible otherwise you will be injecting just water (because it's heavier)

2: Methanol is hydrophilic (it likes water) so it is soluble.

Stick with the methanol injection. The DEA will look at this chemical as well, but if it's the only thing flagging and if they come a knock knock, point them to your 'crack' (i.e. boosted car and take them for a spin )

Any more -----&gt; ?'s

Look at my name.

 

Dea wil be alot more interested in people buying toulene regularly.... **** some [freak]ing road flares, NaOH, Thrust and a bunch of pseudo and youre good to go (well, almost)... LOL

Yeah lucky I dont live in the states. Also if you dont do drugs/have/sell them, I dont see what the problem is if DEA comes knocking and asks you about it. Cant you just tell them that I use it for racing.

But as a thinner, they are mixed together along with other items. In pure form, they CAN be used to make stuff. You'd be surprised at how many common household items can be used to make serious bombs and drugs.

One thing to note, you won't gain much from injecting Xy/toluene - it makes up ~30% of normal gas already. You will be injecting fuel that is metered poorly (by fuel injection standards), so your power may suffer from AFR swings.

As for the DEA looking for methanol buyers - its far easier to claim a racing use for it, and that you can get it in 40/60 mixtures in the form of most blue -35* washer fluid. A can or two of the HEET fuel products and its 50/50 for $3/gallon.

I think your quest for 400whp on a boosted 11:1 H22 was cut short the second you ordered those pistons. You're around a dynmic compression of ~20:1, and 93 octane by itself can start knocking at 18:1. Its more complicated than that, but that's it in a nutshell. Since you already have meth, just get 100 octane and be done with it. But the difference between 370whp and 401whp isn't much at all concerning drag numbers.

I didnt order pistons, it is a bone stock JDM h22 that was an overheat victim when i got it, so I had the head milled a good amount to straighten it out, and the block plained as well, and also used a higher compression cometic head gasket to put it back together (i opened it before i noticed that they sent the wrong one) so 11:1 is an estimate, but it has been running like a champ at 10ish psi for 3 years and has a power curve that looks NA because it spools so well.

 

yea tolulene has been around for awhile I seen guys that use to run it on the supercharged ford lightenings back in the day...And with 300 million people in America I don't think the DEA is going to be knockin your door down for you having a few gallons of this long as your home door is nothing like Frank Lewis'!!! you should be fine!!!
