Not Ranked
AFR and Jet size
I had a friend hook his AFR gauge up to my 408CU stroker mild CAM with a 770 street avenger (Vacuum secondary) Primary jets 77 Secondary Jets 83 and got the following
AFR
Idle 14.0
WOT 12.5
Cruise 3k load 10.9
I assume I need to down size my primary jets but by how many Jet Sizes. How many Jet sizes will raise AFR by 1 full point. Will that affect my WOT by a percentage and if so approx how much, I will be able to use the gauge again but wanted to use some logic in jet selection.
