Hey everyone. I have a 96 accord, 98 jdm h22, and a 80hp Direct Port NX setup. The highest octance you can get here in colorado is 91 besides the track which is 45 minutes away. I have been "told" that octane boosters arent good for the fuel solenoid. Is that the same for toluene and xylene? Do they have any lead components that would damage the sensors? Also, is there a necessity to add Marvel Mystery Oil for toluene? I have searched and searched but found very little when it comes to nitrous and toluene. Thanks.
with an 80 horse dp shot on a JDM H22 you should be able to run 91 octane, retard your timing a few degrees (3-4) and you *might* be able to run 1 step colder plugs, but 2 step colder plugs would be safer (your best bet is to try both setups out and check for detonation. As for the octane booster, I don't think you will have any problems. NX sells an octane booster and doesn't mention anything about other brands eating up your noids.
I use ACE xylol. Xylene and Toulene. I use a 30% mix, which w/ 91 octane yeilds about 99 octane. Hasn't harmed anything so far, but I also run dry rather than wet. Never heard of adding MMO to it either...

In CA, 91 octane is the highest usually available.
A 10-20% mix of xylol when running off the bottle makes a noticeable difference in power. Haven't dynoed it yet.

What I use, ACE xylol, is a blend of xylene and toulene.
Oh yeah, forgot! Xylene and Toulene are both popular ingredients in octane booster formulas. Buying a $8 gallon is much better than buying a $5 pint! It shouldn't cause fuel solenoid issues, but you're gonna be using a lot more in a 30% mix than you'd ever get from a bottle of octane boost.
alphajesse---do you use that ACE xylol stuff straight with nothing else added besides the pump gas? I mean in terms of lubricants or anything like that. Thanks
It shouldn't affect normal driving. An increased octane level will help you fight detonation, typically in high boost applications. Considering that our engine isn't under heavy boost, I don't think it is necessary with nitrous, however, it couldn't hurt. I would say the best way to fight detonation with nitrous engines is colder plugs and ignition timing.

Just straight ACE xylol, man. 30% mix for n2o runs, 20% for racing off the bottle.
jnkoh, what kind of gas is 'high octane' where you live? In CA best I can normally get is 91! It's not enough! Even my kit's instructions say to use a minimum of 92 octane...

You are correct. You need to add lubricants as pure Toluene is 'dry'. Ive been looking into this for a while so I can run more boost in my Supra. Here are a few good sights on this topic:
conundrum, I don't see where toulene or xylene are ever called 'dry' in the articles you posted. The 2nd two advocate toulene mixed with mineral spirits, and atf, but the 3rd article only calls methanol, ethanol and other alchohols 'drying' agents. The 1st one states that anything up to 45% TOTAL (including any already present in the gas) is still safe.
The last article also cites methanol as a corrosion risk, and suggests a small amount of water be adder. I will stand by xylene and toulene not needing any additional lubricants.
Quote:
Most stories of corrosion etc, are derived from anhydrous methanol corrosion of light metals (aluminum, magnesium), however the addition of either 0.5% water to pure methanol, or corrosion inhibitors to methanol/gasoline blends will prevent this. If you observe corrosion, talk to your gasoline supplier. Oxygenated fuels may either swell or shrink some elastomers on older cars, depending on the aromatic and olefin content of the fuels. Cars later than 1990 should not experience compatibility problems, and cars later than 1994 should not experience driveability problems, but they will experience increased fuel consumption, depending on the state of tune and engine management system.
theres a good article in Modified magazine about it(i think the mag is new..never saw it before or heard of it but im reading it right now.....its awesome)on page 118 and 119 of the September 03 issue
