Default Largest dry shot on stock injectors?

Thats about the only other thing I need to know about my car before I finish up my install and get a few more odds and ends to clean it up.

Lid, full exhaust, LS6 manifold *on its way*, only performance mods car will have upon the initiation of the nitrous. I will be having it tuned before I just go out and spray due to my lack of having a WB. Though I wanted to know what is the largest shot I can run on my stock injectors, and I guess while I'm at it what would be the largest shot I can safely run on my stock fuel pump, with XX lb injectors. Safely run on my stock fuel pump.

This way if I decide to upgrade, I at least know what my limits are and how to raise those limits with the correct parts.

Current jetting is 100 shot, I assume its a rwhp shot, single NX nozzle at .052

*If this has been covered, search isn't working for me. Even with searching with the new search commands*

I have heard 125-150 is the max on stock pump and injectors.

No prob mang. I would watch the a/f and make sure that you are not getting ang kr. Also make sure that the nozzle is pointed in the correct direction and location in relation to the maf. I dont know alot about dry shots as I have always either sprayed a wet plate or a fogger. Its just easier and safer imo. Josh

The math for sizing injectors can be found in the wet vs dry thread. It's based on power known, or power sought.

My shot made 128 HP and 139 TQ on stock fuel pump and injectors. Single nozzle dry into the side of the airbox.

Just be safe and get and aftermarket fuel pump. Its around $160 for a LOT of insurance. Plus your gona need it if you do H/C later on. Might as well just do it now.
