Octane boosters... how much help against knock?

[Shpyder]

So, my organic chemistry professor is a genius. He was assistant to Linus Pauling for a long time. Has been teaching since before the dinosuars. And he does neat stuff, like grabs a $7 bottle of octane booster off Kragen's shelf, goes to the lab, does a gas chromatography on it, identifies toluene and ethylene, works out the ratios, and distills himself a couple of gallons of octane booster he can use in his 1970-something Buick Grand National (whatever that is) at a comparitive rate of $0.8 a bottle. . Oh hell yes, my fuckin idol!


His car needs 100 octane so it doesnt knock, so he throws in octane booster per gas tank. How much does an off-the-shelf octane booster help DSMs? Any one tried any before?

Buick Grand Nationals are rare birds. Don't be supprised if you ever see one handing a Supra its ass!

Turbo Mag did a large review 6 months ago on octain boosters. NOS won the prize. It depends on what grade of gas is used, what the ratio mixtures are when you mix it. Off the shelf boosters will raise octain ratings 2-5 points depending on those two varitables.

Waste of money in my mind. Typical octane booster off the shelf ~$4.00, which will give you like an extra 2 octane points. Not worth it.

Your questions been answered.

Just rememeber that 2 points advertised on the octane booster bottle translates into 0.2 points of actual octane.

For example you are now running 91.2 octane gas as opposed to 91.0 octane.

Not worth the money, you are better off going with a methanol injection kit.

Also, raising the octane of the gas doesn't give you any more power, in itself. It dispurses the energy of the fuel, making it less likely to knock.

This, in turn, will allow you to run higher boost which makes more power. So I guess if you were to dump in about 20 bottles of octane boost and cranked down the MBC you would make some more power.

You can make your own octane booster from paint thinner. Just go to homedepot and buy some xylol(thats what its called), in the paint section. Well I'm not going to explain the whole thing, just read these.

I have never tried it in my turbo laser but parents have a 5.0 h.o stang and when i ran it with premium and a bottle of octane booster... i barly noticed a difference from just premium.
