  • Correct a/f ratio for 3.4

    I need to know what the correct a/f ratio for a 3.4 is? At like idle, half, and wot. I thought it was around 11:1. I could be wrong though.

    As a general rule of thumb, 14.7:1 is the perfect ratio. At WOT however, you want it slightly rich. I think 11:1 is for non streetable race cars, I am pretty sure it is too rich for a daily driven L32. It will probably fail emmisions inspections if you have them.

      Well we don't have emissions here in Iowa :D But yeah, I want to keep it streetable. So around 14.7:1 then like 14.2:1 or so for WOT. I'm looking to make the most power with the mods in the sig. I plan to go to a local dealership and run some a/f tests then if needed get a AFPR and tune from there with my own a/f ratio guage.
      Anyone else have any comments or ideas?
