stinger plate jetting I am running the stinger on my efi set up I put it on the dyno today and it was super fat. I was using .78 n2o jet and .44 fuel jet. My fuel pressure was at 50 psi ... I put those on to the solenoid side of the hard line and on the plate side I was using the .136 jet on both sides that were in the plate when it came to me... was this correct with the .136 jets on the nitrous and fuel side... and was this the reason it was super rich.
The .044 fuel jet is the reason for it being rich. Who ever you bought the kit from used the .136 jet to seal the hard lines so they don't leak. On my Stinger kit I put -3an fittings in the solenoid that attach to the hardline and the jet are in the plate.
That jetting is very rich. Our jet chart calls for a 36 fuel jet @ 45PSI or a 35 fuel jet at 55psi. I would put the 35 jet in it. The .136 jets are just flow thru jets to seal the fittings at the plate. Let me know if you need any other help.
