How much N2O could the stock injectors on a '99 Silverado with a 5.3L keep up with (on a dry shot of nitrous)? How many lbs/hr. are the stock injectors if anyone knows? Thanks. this is the best forum! <img src="graemlins/fluffy.gif" border="0" alt="[Fluffy]" />

 

not sure about dry, but ive heard of people running up to 150shot on their wet kits. I would say you are safe with a 100 shot.

 

I personally like to keep it 100 shot and under for dry shots and then use the TNT wet kit for 100 shot and up..With wet it doesn`t matter how big your injectors are but how much fuel your fuel pump can flow.. I am pretty sure you are safe upto 400 RWHP on the pump..
