Has any actually tried this stuff??? Any feed back would be greatly appriciated as I would love to freak my friend out and tell him the boost was all from my recent flapper mod
!!

Maybe I missed something but tried what stuff?

the add for the "AMAZING GAS DROPS" thats been at the top of the forum for like 5 weeks, garanteed to boost ponies by 5%.

ok quick lesson on octane
it doenst not and was not designed to boost performance
all octane does is resist detonation. lower octanes detonate faster, higher octances detonate slower
high octanes are needed for high compression engines say in turbo cars, motorcycles etc
low octane in your average run if the mill sedan because there isnt a lot of engine compression.
have you heard of engine knock? engine knock is when the compression of the engine makes the gas explode rather than the spark plug making the gas burn. higher octane is harder to explode just from pressure. in effect higher octane is harder to ignite.
now if you have a vehicle that is tuned to run on 87 octane higher will not make it run better, because the power is from the fuel mixing with air and burning. since higher octane is harder to burn you may even lose power because it wont burn all the way under the lower compression.
now say you have the dynojet ignition module, you could benefit from higher octane there by advancing the ignition beyond oem.
you can get some power this way at the expense of a greater chance of engine knock
here is a link that can explain it all better

I thought turbocharged and supercharged engines dialed back on compression ratio to compensate for the added intake pressure of forced induction. Maybe I'm mistaken?

They do, but the higher the octane, the less they have to dial back.

they do,
my turbo eclipse, i had to dial back from 10:1 to 8.8 to 1 to be able to run pump gas
however when you dial back compression you lose hp
it takes more boost to get the same amount of hp
to compenstate for the loss of hp i had to up the boost and to still use pump gas i had to add methanol injection
