home brew octane booster
Ya it works.Hundreds of guys have been using it for years.Do a search on the GN forums.I've used it myself.I've run as much as 23#s of boost with this mix.Motor pings on 94 octane and you add the mix and it stops pinging.That's proof enough for me.Don't need a dyno.
BUMP for some more LOVE on this subject! I am in Florida (JAX) and there are no e85 pumps for civilian use, and the Sunoco's 110 is lead base as well as $$$. A cheap alt is greatly appreciated

Try this stuff if you can find it.... http://en.wikipedia.org/wiki/Propylene_oxide
^^^^ Bump what he said!
also, if one were to add to fuels together in equal amounts, would the new octane be an average of the two fuels?
also, for the E-85 adders, doesnt E-85 take about 3X% more fuel to run, so adding e-85 to your tank, would that not make your fuel less powerful?

AFR for E-85 is 9.8:1 where as gas is 14.7:1.It takes more E-85 to reach the same as gas.
Ethanol has less energy than gasoline. Gasoline has 117600 BTU per gallon, ethanol 67000 BTU per gallon.
Anyone who tells you they actually picked up MPG by using E-85 is full of ****!. When it was first advertised in our area I remember comercials with people actually claiming the increase in MPG or major gains in power. My 07' Avalanche was OK on gas and an absolute hog on E85.

So, back to the OP, is it a a no bs formula that can be used on a non-sensor equipped engine(gen-1) sbc? Just wondering if anyone on here has tried this formula, the ATF part kinda scares me. I'm really curious about this topic as well!

I agree with 94zgreenmachine.
If you are going to do e85, you will need bigger injectors and a good tune. But expect to get 1/2 of your mileage. The flip side is your getting 105 octane for $2 instead of $6. So even if you used 2x as much, your still saving money. But its also hard to find.
You could also do like the flex fuel cars, and add a ethenol sensor so you could just mix whatever you wanted and it would adjust the tune accordingly.
How much boost are you planning on running? Your going to do this on top of meth?

I run E85 in my Grand National and as said above you will use more fuel while running it. I had to go up about 30% on fuel flow BUT was able to go from 15# boost to 24# with no knock. Keep in mind my GN is an 85 so no intercooler there...just lots of hot air forced into the motor. Not only does the E85 have a better octane rating but will decrease the temperature of the engine at the same time. There's not many downsides other than decreased fuel mileage and slights harder starting in cold temperatures. You also wouldnt want to store the car with a tank full of E85 because it will attract alot of moisture into the gas tank.

so if I don't have a F.I aplication this formula for home made race gas isn't going 2 work well in my car? I figured it should do something or why would they sell it in the stores for every1 to buy? I have read 100's of threads on this topic 2day & still not sure on this. I am thinking of makin formula #2 since its higher octaine
