Ive been told alky is good for 10% increase in power. I ran it on my 10mil and it does make shit run good. easy to tune too. Stay away from e-85, it doesnt do shit for power. Put e-85 on a 770 raptor and it didnt do shit but make it hard to tune. But it is similiar to alky, you have to increase your fuel intake about 35% much like alky. Just remember E-85 is ethanol, not methanol so it doesnt make more power, it is just an alternative fuel for vehicles.
