Just to be sure we are talking about the same thing...
that is what I'm talking about.
for how much they are charging you for that stuff at the link, I would suggest what i use in my 74 Nova dragcar....Go to a RC hobby shop and get a gallon of 40% Nitromethane engine fuel and add it to the gas in your car when at the track. I put one gallon of that in with 10-11 gallons of 110 octane in my 12 gallon JAZ fuelcell and boy does she pep up! i figure it equates to around 3-4%of nitromethane in the overall mixture.
now keep in mind this is on a 350 sbc with a N2O plate and more supporting mods but nitromethane sure lets ya bring more to the table! lol
on a side note the 0.21 cubic inch PiccoNovarosi engine in my gas powered RC boat is rated at 3.2 brake Hp at 20,000rpm, on 40% nitro glowfuel! but lkately my dragcar has been getting all the attention lol.
and back to the purpose of this thread I started using acetone in my 84 toyota cressida and my 68 Ford f250, when i first read the article. the toyota is still on it'* first tank with it at ~2.5oz per 10 gallons (added just under 4 oz at a 15gallon fillup) and it looks like (with no other changes in driving) I will be getting ~10% increase in fuel ecconomy--from 24mpg to 26!
the Ford is the one where i have noticed a remarkable increase!
68 390 cid V8 with a 2bbl carb I put 3.5oz in the first tank (13gallon behind the bench seat) and woah! i went from 8mpg to 10! I have the idle screws in 1/2 turn farther than they have ever been! and the plugs indicated she was still rich so i got a carb rebuild kit and went 1 size smaller on the main metering jets (from 70'* to 6
and so far on this tank of gas/acetone it looks like 11mpg but i still have a 1/2 tank to burn through before i know for sure! this may not be a valid comparison for most of you, but realise that the mpg on the F250 went up almost 25%!!! part may be to the rebuild (on this tankfull anyway) but the carb was clean and i only needed the kit for the bowl gaskets etc.
still I am happy with the results so far I will have to see how it all pans out, so far it'* been good! enough so that i may play with the acetone in my dragcar this season with the RC glowfuel! hell if i blow it up it just means that i will have to finish my turbocharged 400sbc sooner rather than later!
