Before I pull the trigger on a Dry N20 setup I just wanted to run this by you guys real quick. Im new to Nitrous, so forgive me if Im missing something...

Currently I am running a LG Motorsports GX51 cam specs are 228/232 .588 .574 112 LSA. I would like to know what you guys think is a reasonable shot size with that cam on an otherwise stock fuel system.

 

Around how much is she making NA? I'm going to say not too much with a dry system on the stock injectors.

She is doing 375rwhp on cam only, so you think a 75 shot is doable, or will I run out of injector?

 

You can do a 125 alllll day long. I have done this on many customer's rides, with a few more mods then you, and they ALL are still living. Change your plugs, have your tune checked, and you'll be fine.

 

You might squeek by on a 75, it will be very close. The only way to know for sure would be to log your injector duty cycle, which I would suggest doing if you can.

450 rwhp is about max in an all motor app that the stock ~28 lb injectors can provide. When you spray, you will want to run slightly richer than on motor so I would say you would be able to spray 50-75 and you will max out the injectors and start to lean out. Get some new larger injectors and go to town though.
