on my S10 my fuel cell has 2 outlets on the Sump.

one side is feeding the fuel rail and a 50 shot off the rail.

I have a Aeromotive FPR and another Inline 255 im goin to run for the other 2 big kits.

What would yall set the pressure to for the nitrous side?

The engine side is goin to be using a 99-02 Return rail. so once i get a reading on that to make sure its ~60psi ill know what jets to use.

Should i run the Aeromotive FPR at 60psi also? i think it maxes out at 70psi.

Depends on how it hooks, first kit is goin to be a 125, second a 75 and a third kit 50..
if it doesnt hook then ill swap the 75 first and the 125 second.

Cammed 4.8 on 116oct

 

 

Are the systems non directport? How much are you spraying on each stage..

If 70 psi is the max I would stay at 55-60. No need to push the pump near it's limit since you can just change the jet.

 

Just a plate and a nozzle.. 75 on the plate and 50 on the nozzle till i get the tune sorted out then ill slowly up both shots.


I think im just goin to go with 45psi and hook up the vacuum reference so when i put the turbo on it should be good to go.



Sorry for the late replys, i dont get on the net much anymore..

Thanks!

 

Call and ask the maker of the plate your using. I use NX shark nozzle's and Nitrous Express told me 10 psi would be perfect.

 

i cant remember who makes it, i have 3 of them. i know one is a old nitrous outlet, and i think one is a nitrous express, and the other is a home made one.

the jetting changes from a low pressure (7-15psi) to a high pressure (55-65psi)

You need a base chart to go from then good tuning.
