Guys, i've read complete combustion is at 12:1 on the nitrous. I guess you want a "safe" set up and run it a bit rich.
What AFR's are you heavy hitters tuning for on the nitrous?.. i've heard as rich as 10.0:1 and as lean as high 11's...
??
Thanks!

 

I think TNT rates there kits at 10.8:1.
I try and keep mine lower then 11.5:1 on a 200 shot.
