ok most of you are lucky enough to atleast get 93 octane pump gas. In maine i can only get 91 gasahol. Yeah it sucks i know. I noticed in NH (this was on my motorcycle actually) i got 93 sunoco with no ethanol. I also got colder engine temps by about 6 degrees (it has a digital temp gauge) and i got about 40 miles more per tank. In maine i don't have that option and i can't drive all the way over there just for gas. A local place sells vp110 leaded fuel. i don't have a cat so i'm not to worried about running that. I also considered mixing 3 gallons of vp110 with about 7 gallons of 91. I would like your opinions on that and also the possibily of mixing a gallon of xylene or something like that with a tank a fuel. There is also a local air port that sells 100ll avgas but i don't know of anyone ever using that. The avgas is about $5.00 The vp110 is $8.15. Not really sure what zxlene goes for. I also can not for some reason convince any of the local sunoco stations to get the sunoco 100.
Before you guys scream out SEARCH!!! I already did and there isn't much on leaded fuels and xylene
The B/S part of it all is that maine does not have an E10 law. But all gas in maine is 10% ethanol.

 

If you can't get high octane gas and have no e85 availability in your area look into m/i

 

considering that to i can always get cans if heat and jugs of washer fluid

 

+1, E85 is the way to go. And, if not available, I don't know anyone who does not have access to -20 deg Peak washer fluid all year round (takes me two weeks to run through one $1 jug of washer fluid). Those are your easiest answers to increasing octane.

 

If E85 is readily available it's a total no-brainer. If not, you can make do on 91, most folks in CA do. We have the same E10 91 octane pisswater you guys get up there.

 

the nearest e85 station is in Mass and by the time i got home my tank would be empty. Water meth doesn't sound to bad, i've been considering it for a while. I'm kind of suprised no one has tried the leaded fuel.

 

Like they said E85 FTW! Add 1 gallon and you'll be right around 93 if I'm not mistaken. I ran 25% in an OBD 2 dodge ram with no ill effects. Smells great too!

Edit: Just read the above sorry.

Leaded fuel isn't good for your O2 sensor.

You could add a gallon of toulene but that could be expensive.

 

If you can find it for a decent price Toluene is a great additive.
http://en.wikipedia.org/wiki/Toluene
Once was very cheap. Just a paint thinner to most. Now that it is used for meth it has become harder to get and very pricey. :-( Is already one of the Octane boosters in Unleaded. Be aware. Eats paint and rubber in heavy concentration. Improves flame propagation. Serious power in 2 strokes. Adds notable top gear RPM. Runs cooler. Stock modern motors can run 10% no problem. Nice throttle response etc... At 30% the tune is messed up. Before the price hike I used it to clean valves/ injectors/ carbs in my vehicles.... Used it to keep bike carbs clean so I did not have to pull them.

Check out some paint stores of chemical supplies for 5 gallon cans. Be aware of how to handle it. fyi - Toluol Is Toluene based but not the same stuff.

Octane rating
For 10 gallons of calif. gas and a gallon of toluene,

(10 * 91) + (1 * 114) =
(910) + (114) = 1024

1024 ÷ 11 = 93.09 octane

They used to run almost straight toulene in the turbo F1 cars back in the late '70s- early '80s. They would run 85% toulene and 15% n-heptane as a buffer. They would run 50-60 psi during the race and up to 70-80 psi during qualifing, IIRC. Making up to 1400 HP on a 1.5L 4 cylinder.

 

that is incredible. are you sure about those numbers? i can only imagine the engineering that went into those engines.

 

I run 100LL avgas in my 1.8L up to 26psi. Runs great no problems. Here at our small airport, you can drive up and fill with a credit card. $4.50 at the pump. We burn it in our turbo 2stroke sleds also. At the shop in bulk, we pay $4.26. Avgas octane is rated differently than pump gas. It equals 110 octane for deto.

 

Modzzilla with the red "400rwhp" car on eBay right now?

 

Yes

Yep, straight out of the Motorbooks Workshop series Turbocharging Performance Handbook among other sources. I actually think I'm a little on the low side. I'm getting old and my sometimers acts up more often.

Nelson Piquiet dominated the 1983 F1 season with a BMW based cast iron block 1.5L at almost 1400 HP!

In 2001 GM performance developed a version of the Ecotech that hit 1400HP for their drag car.

Bob Norwood built a custom dragster running a twin turbo 350 cubic inch 4 cylinder on nitromethane at somewhere around 4000 HP!

Granted they were all custom, purpose built machines on massive budgets but very cool.
Turboz is cool!

 

there is actually a lot of info online about adding acetone to fuel as well. but i can't find an actual octane for it. i'm going to try 2 gallons of vp110 to 8 gallons of 91 first. that will put me around 94.8 octane. i'm also going to save or start to make a water meth kit.

 

Acetone is a little risky. It will soften rubber and plastic more because it stays a liquid longer.
