i know what AFR to shoot for on nitrous (about 11.1) but when im not on the nitrous what should i be looking to set my NA AFR? or does my fuel solenoid take care of richening the fuel system? my current WOT AFR for all motor is about 13.0- 13.5

 

my nitrous motor that lasted me a good month i ran about 11 to 1 and it stayed that way when the nitrous hit. i had a secondary fuel cell and pump for the system tho. not sure about ur setup but mine wen nitrous was sprayin so was some extra fuel also.

 

Why did it last a month? Stand alone fuel system wont affect anything with AFR (except if running higher octane) but I will be putting a stand alone fuel on it later and I have a 4150 carb plate system with a nitrous and fuel solenoid.

If the AFR doesn't change than I guess I need to work on richening it up 2 numbers

 

here is what i have so far. (mechanical 110 pump) after the fuel pressure regulator, i have the right side going directly to primaries. on the left side, Y'd off to the secondaries and then to the fuel solenoid with the FPSS switched spliced into the line. not my favorite way to go this route with nitrous but itll do for a 100 shot for now

also i think im setting fuel pressure at 5. should i set it a number or 2 higher to be on safe side

 

12.5:1 is normal for N/A AFR

 

high 12s really, but i guess im just gonna set my na afr around 11.5
