I have a 5177 kit and of the 2 lines running to the lid one of them broke a few months ago so I only have one line running to the lid. If i wanted to use a 125 shot what pill size would I need since I am only using 1? Also since it is a 100 shot and I am not running 2 lines anymore does that make it a 50 shot? I have noticed it is much slower with just the 1 spraying? Someone help this newb to nitrous, lol.

 

NV got a 61

 

Yea, one line is half the output. A NOS rated 100hp shot is really about 85hp at the rear wheels. So, a single 61 is close to a 150hp at the rear wheels. This is because you can't just add the two together and go single, the math doesn't work that way.
Here's the math:
.71(com den) x size of one jet x 2 = single jet size
so,
.71 x 33 x 2 = 46.86 single jet or .047 jet equals a 100hp shot

You probably wonder why a 33 instead of a .032 jet. It's vcause a true 100hp at crank the way NOS does it is dual .033's not dual .032's.

 

O ****, so your telling me I am now running a single 150 shot?? Thats crazy, my car is almost stock, wont this be too much for my internals to handle? Its a single 61 by the way..

 

It's not that your car can't handle it, you'll run out of injectors and probably close on pump, and lean that way is not good.

 

Thanks for the info. I have been told by the tuner that i am already running 110% on my stock injectors with the 100 shot so I will definitely need bigger injectors, and a new fuel pump. Thanks guys.
