I´m using CTR pistons and skunk2 stage 1 cams, how much can I spray with this set up.

the kit I will be using is a zex but dont know if I sould go with a 65 or stay with a 55.

I have a FPR, STR fuel rail, B&M fuel pump and RC 270 injectors, I also have TI retainers and springs from SKUNK2.

thanks in advance

Because you're using OEM pistons, you're not going to want to go over a 75 shot. To be safe, I would go to a dyno and do a few 3rd gear pulls shooting 50, 60, and 70 shots. If you don't get detonation go for the 70 shot. If you don't want to go to a dyno keep it at a 50 shot.

The main reason as to why you should take your car to a dyno to tune your nitrous to your engine is because most, if not all dynos, have wideband o2 sensors that are far more precise at detecting your air-fuel ratio.
There is an article on an wideband air-fuel monitor that you can install in your car in the current Super Street. The product runs nearly a grand though, MSRP.

I know about all that and thats why I know how to check plugs so it wont lean out, but having bigger injectors and a fields controller I dont think I´ll have a prob with fuel but I guess to be on the safe side I´m gonna stick with a 55 shot for the time being.

thanks
