Nitrous Jetting on E85

[justa03]

Hey guys looking to put a 50 shot on my car to drop IAT's a bit since im spinning the 2.2 to 21 psi. From what I found on NX's site it says a 35 for nitrous and a 18 on the nitrous side. I multiplied this by 1.28 and came up with 23 jet. This would be on a return system set at 60 psi. I also found on theyre site where it say for going by fuel pressure it shows a chart for 60 psi with nitrous jet at 31 and fuel jet at 19. Any inputs or thoughts on this guys?

I went with a 30% larger jet over the gas jetting, my base pressure is 39psi, so I run a 35n/26f. When I called them the jetting I was told was 23. On the 26 jet, the wide band nearly mirrors the boost only. Every car is probably a little different, might take a few jet changes to nail it, but probably better to start a little rich.

I see on the site it says the jetting for fuel pressure says 40psi (23) vs 60psi (22) only one jet size different.

You might give them a call.

I saw a 10 degree reduction in IAT on my 2.6L
