Nitrous and Speed-Pro hypereutectic pistons

Thinking about adding nitrous to the 496, running Speed Pro hypers at 10.3 to 1 c/r. Would they take a 100 - 150hp shot if I ran a separate enrichment tank with 110 octane race fuel? Engine was built to run 93 pump gas. I have no experience with NO2 and would appreciate your input.

Pull out about 4 degrees of spark timing and check and verify your flowing fuel pressure going to your fuel solenoid and you'll be good to go.

A 100-150hp shot is a very mild shot on a big motor like that.

N2O and SP hypers

My rule of thumb is to pull out 2degrees timing for every 50 horsepower. F-bird has you covered.

With only a 150hp+/- shot any of the popular brand of kits will work fine.
My next kit will be a ZEX. Choosen for it's perimeter spray pattern. I run a dual plane manifold and these perimeter plate kits are toted to have more even nitrous/fuel distribution when used on dual plane manifolds. I like you are not looking for a killer system. Just one that works well.

Have used NOS and Nitrous Express in the past. Had a "Magnum 4+" system before. Was a real weapon. Made a ton of power. No longer made.
Never had any real problems with any of them. They all need a certain amount of mantainance like cleaning the nitrous filter and once in awhile a solenoid will crap out. Cleanlyness is next to godlyness when it comes to nitrous plumbing.
As long as your fuel system is set up to deliver a steady supply of fuel at the recomended pressure to the fuel solenoid and your wiring install is good you won't have big problems with any of the different brands of Nitrous systems at the power levels you want to use.
On a 496ci motor, a 150hp shot is pretty tame. You're going to want to up the anti sooner than later to a bigger more powerfull shot. Buy a system capable of 250 to 300hp and start at 150hp level.
