Can someone help me? I am going to buy a fpss but i need one that will cut off the nitrous if the fuel press drops below 58psi right? Where can I get one, or who has a part number so I buy the right one. I tried doing a search but came up with no solid info.Thanks

 

Most FPSS are adjustable so you can set it where you want it to be. Adjustments are made via a allan key and twisting it left or right. Below is a link to our FPSS:

All the nitrous sponsors here sell them. Harrisspeedworks, Nitrous Outlet, Dynotune, etc.

 

Good choice on using one. Hopefully I install my NX kit this month, and I hope to get the FPSS dialed in.

Lot's of peeps had issues with them, but I am determined to get it functional.

 

You're right, some people do have problems with them. 99% of the time it is due to not having them adjusted correctly.

How do you properly adjust them?

 

Yup good question, I know there's a lot of trial and error. Which is where many have given up (no patience?)

 

Send me a PM with your email address and I'll send an instruction set.

We offer the Hobbs FPSS. http://www.dynotunenitrous.com/store...?idproduct=135
We test and calibrate every unit before it leaves our facility. They are pre set by us at 35 psi so you know where you are starting if you need to adjust it. We also provide complete instuctions as well as a chrome fitting and required connectors.

I don't have the instruction sheet in front of me, but it's roughly 5psi per one 1/4 turn right??
