OK back to the topic..........I would recommend starting out at the 50 to 75 HP level. You will feel it, your not going to hurt your engine, your bottle will last alot longer and you won't have to run a serious fuel system to the NOs fuel solenoid. I ran 250 HP shot on my Challenger, bottle is too low to use again on the third 1/4 mile run ( like moper said) it was a
RUSH though!
I will have it available on my Challey when it is back running, but it will only be at the 50 to 75 HP level.
