Well unless you buy meth in bulk it's about $10 a gallon but yes you could mix it to make a Mxx blend like a Exx blend in the states. So you would have to tune for it and mix it in a high enough ratio to bump up the octane level. That's why I'm gonna run a 5th injector on a dedicated stand alone fuel system running 100% meth next year I'm hoping the 5th injector can come on smoothly enough to run it at lower loads than my meth kit and with a boost referenced fuel pressure regulator with boost the overall flow of the system will increase. So it'll be like running 600cc/min off boost and 850 on boost (just random numbers can tell you real ones if you'd like)

I got some good info here.

Here are some common ways to boost your octane using off the shelf products. I pulled this off another car site.

Formula #1 - Toluene
R+M/2.........114
Cost...........$2.50/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 $3/gal at chemical supply houses or paint stores.

Formula #2 - Xylene
R+M/2.........117
Cost...........$2.75/gal

Mixtures with 92 Octane Premium
10%...........94.5 Octane
20%...........97.0 Octane
30%...........99.5 Octane

Notes: Similar to Toluene. 12-16 ounces will only raise octane 2-3 *points*, ie. from 92 to 92.3. Usually mixed with Toluene and advertised as *race formula*.


Formula #3 - Methyl-tertiary-butyl-ether (MTBE)
R+M/2.........118
Cost...........$3.50/gal

Mixtures with 92 Octane Premium
10%...........94.6 Octane
20%...........97.2 Octane
30%...........99.8 Octane

Notes: Oxygenate. Very common in octane booster products. Has lower BTU ontent than toluene or xylene, but oxygenate effect makes the gasoline burn better and produce more energy.

Formula #4 - Methanol or Ethanol
R+M/2.........101
Cost...........$0.60 - $1.75/gal

Mixtures with 92 Octane Premium
10%...........94.3 Octane (Methanol)
10%...........94.7 Octane (Ethanol)
20%...........Not Recommended

Notes: Methanol is wood alcohol. Ethanol is grain alcohol and found in Gasohol in 10% ratios. Both alcohols are mildly corrosive and will eat gas tank linings, rubber and aluminum if used in excessive ratios. Main ingredient in "Gas Dryers", combine with water.


Formula #5 - Isopropyl Alcohol and Tertiary Butyl Alcohol
R+M/2.........101
Cost...........$0.60-$1.50/gal

Mixtures with 92 Octane Premium
10%...........94.5 Octane
20%...........Not Recommended
30%...........Not Recommended

Notes: Similar to Methanol/Ethanol. Isopropyl Alcohol is simply rubbing alcohol.


Sample Mixture

To make your own octane booster, it is easiest to make up a large batch, and then bottle it up in "dosage-size" uses. Below is the basic formula of one of the popular octane booster products. To make eight 16 ounce bottles (128 oz = 1 gal):

100 oz of toluene for octane boost
25 oz of mineral spirits (cleaning agent)
3 oz of transmission fluid (lubricating agent)

This product is advertised as "octane booster with cleaning agent *and* lubricating agent!". Diesel fuel or kerosene can be substituted for mineral spirits and light turbine oil can be substituted for transmission fluid. Color can be added with petroleum dyes.

if only this stuff was as cheap here lol

Ya where can he get meth for $1.75 a gallon?

lol I wish these are us prices

KMO43

I'm not much on mixing for DD. What meth nozzle are you going with?

tomj77

iTrader: (2)

I think its a 7gph

ill figure this crap out for a project next year, ur idea does sound awesome though 5th injector injecting something extra.

KMO43

It's expensive but you can have way more failsafes in place I need to see how smooth the controller works I'm guessing way smoother than a big pump kicking on and off. I'm guessing you have the 375cc/min nozzle if it's a snow kit

just so you guys know, these days most retailers add ethanol even to their premium;
so you might ve experiencing issues with e-blended 91 vs e-blended 94;
I am unsure of esso, but 99.998% sure that Shell NEVER puts ethanol in their premium gas.

I personally am sceptical of anything other than Shell or Esso gas;
I do occasionally fill at Costco, but thats a risk i choose to take.

yes that is it. I have a number 4 and 5 nozzle. I use the 5 I believe. its one step under the highest flowing one, I had 300 hp at the time so I sized it to that.
yes that sounds like an awesome idea. fail safe would be controlled by the ecu u get with it right? get a nice big cell in the trunk and away ya go. sounds like awesome plan. I shall watch u with this. best I saw was on a 1600hp v8 old rx7. had 2 cells one with 91 one with race gas, as soon as the ecu sensed boost the fuel system switched tanks to the race gas. fricken sick setup

KMO43

My failsafe are gonna be the gauges I'll have a fuel pressure gauge that I can see if it has a problem even before hitting boost and the second is my flow gauge that I already have I'll just change the fittings to AN fittings and use that inline too so if I do not see the fuel pressure drop or the injector or controller fail then my failsafe gauge will pull boost. I can get either 5 or 8 gallon cells

KMO43

Shell in Kelowna has the E ratings for their fuels on the pump yes 91 shell has 0 E. I think that blue's switch over proves 94 with 10% E is better. I think you should switch over to 94 too!

Tom you may as well buy drums of e85 and mix it as e30 and make use of those Opel injectors

KMO43

I'd love to run E47 if I didn't have to mix it myself

slapbetcommissioner

iTrader: (3)

Too bad you can't order it by the barel as e47

KMO43

If I was going to mix at all I'd just buy E100

slapbetcommissioner

iTrader: (3)

Didn't know it came in e100

ZZP set their max power on the M62 on E98 I believe

where can u get E85 in drums

tomj77

iTrader: (2)

I don't get how the pulling boost failsafe works. how exactly do u set it up and how does it work

Co-op does not use ethanol in their premium. My car leaned out quite a bit when I went to husky 94.


You can get E85 drums out of the states. I know that's what lots of drag racers at gimli do

Water/Methanol FAILSAFE Device

It's what I was talking with Blue about a month or so ago

KMO43

How much leaner did it get? The extra amount of fuel needed when running an E blend is good to lower EGTs and cool the turbo

New 26 psi tune is sitting in Dustin's email

KMO43

Nice ho much timing did you add and what's the total?

Bluelightning

Went from around 11.8 to around 12.3
