Jet Help

[Redrunner]

Hey I have Compcar Noids with NOS fogger Nozzel and I was wondering when tryin to get 50 shot or 55 shot should I use what Compucar says is a 50 shot or what NOS say is a 50 shot

My bottle stays at 900- 1000 psi all the time and I have stock Fuel pressure I think it is 30 -35 maybe 40 psi

Compucar says that a 50 hp is 37n20 and 26fuel

I dont know what NOS say it is. Also If i do go off of NOs what pack of Jets do i buy

i've been here buy what nos says.i use a 42 n2o 28 on the fuel side thats about 80hp i think thats safe.what you need for a 5o-55 hp is 37 n2o and 26 on fuel side.Any other questions let me no im pritty good with n2o.

The 26 fuel jet is too big for a 50hp shot. You need the 37 N20 and 22 fuel for 50hp. And that is with stock fuel pressure around 32-36 psi. Running the 26 fuel with the 37 N20 will not hurt anything but it will not give you 50hp instead it will probably give you around 40 or so maybe less. If you are unsure about it then go with a jet that is a little rich and then read the plugs then try one jet smaller and read the plugs, I would start with nothing larger than a 24 fuel with the 37N20

did you try this i did a went really lean on my a-f gauge and went bigger richer is always better.

Yes that is what I ran for a long time and I read my plugs often and there ws never any signs of a lean mixture. Also I have bben using the N20 for close to 3yrs now and I still have compression numbers of almost 190 across the board. So I don't think there was ever any lean conditions at all, and the compression results are with the stock internals with 135K on it

Well then i guess you no all about it. My car ran lean its better rich than lean.Right know i'm shooting about 100hp i just went up in jets last tuesday to a 45N20 31 fuel and i have about 220psi in each.How much are you spraying and what do you have done?I'm thinking of going turbo this winter.So cool see ya
