N2O / Fuel / Horsepower Gained.
38/46 50HP <Very Rich Jetting
46/53 75HP <Very Rich Jetting
57/65 100HP <Very Rich Jetting
47/53 100HP <NOS Jetting.
55/61 125HP <NOS Jetting.
73/82 150HP <NOS Jetting.
82/91 175HP <NOS Jetting.
if you go to rich you can run into puddling of the fuel and improper atomization . are they jets from the same company or kit 5 sizes would be a huge change. and running it that advanced might be a reason for a rebuild because the initial charge wont be atomized and if your not running a purge system and get all fuel the computer pulles fuel just as the n2o hits the chamber and bad things can happen.
