I have a nitrous kit for my truck that a friend is putting on a beater offroad truck that he is running in an obstacle course. The jets are 87 N and 67 F. I believe this to be 100 shot jetting maybe 150.

My GMC had 58 psi of fuel pressure. Does someone have a chart that would tell me what the adjustment would be needed dor 40 psi of fuel? The beater is a jeep and we want to run a 100 shot maybe 150.

The nozzle isn't labeled and I bought the kit used. I contacted the seller if they knew what brand it was but trying to see if we can figure this out ASAP. He is racing this pile this sunday.

 

Nitrous Jetting Charts

 

Thank you. My friend found those I wasn't able to last night.
