Im thinking of putting a bottle of it in the next time i fill up, i have to put premium in it due the supercharger...how much octane boost can i put in it and what kinds of things will be different once the octane boost is in?

Well you should notice your passing vettes more and more hehe. So octane booster...As far as stock is concerned it doesn't do much of anything for you. More octane simply allows you to run more boost, more spark advance or hit the nitrous a little safer but if your car is stock and not pinging it really won't do anything that premium wouldn't. If you start modifying your car (higher compression, nitrous, smaller pulley, performance chip) and notice A) the performance isn't quite what you expected or B) you notice a pinging sound on hard accelleration then you could probably benefit from the booster. Thats my thoughts

the bottles of octane booster only raise your octane level by a few tenths.

Actually thats not always true, it depends on what you buy! If it contains hydrocarbons like toluene and oxylene it'll only go up tenths of a point. Methanol or ethanol will bring them up a bit more and MMT (often found in NOS Octane booster) raises the most by far.

My buddy runs toluene in his Civic. That stuff stinks.
