10lb NX bottle and valve/4500psi Nano/Nitro Daves stand alone on the low pressure spring currently @ 8psi. Fast 90 direct port 4 solenoids(2n2o & 2fuel) done by Nitro Dave. That is just a basic overview of the system.

I was told by Nano to turn up the psi on the cell 2psi to accomidate for the added nitrous function. but i am still hitting 10.0 afr on the second half of the track. how low can i turn that low pressure spring psi to adj the afr without rejetting?

 

You don't have a regulator you can adjust? Sounds like you need to take that two pounds back out of it.

 

yes i do have a regulator that i can adjust. and also i did take the 2 lbs back out. i was just curious how low i can go psi wise before i could start having issues. can i put it at 3-4lbs??

 

I don't like getting much under 5psi. If I have to get it that low to get a good plug reading, I'll start taking some fuel jet out of it. I prefer to stay 5psi and above.
