AFRs on stock red-top and black-top
Hey Matt/Pete what are the stock AFRs for the red-top and black-top sr20dets? Thanks
It's actually hard to say because they all have a lot of k's on them now - and a std one is a rare beast indeed. But they all tend to run exceptionally rich as soon as boost comes up - and they just get richer as RPM rises.
I've seen them run between 10 and 11:1 AFR's. It also depends if boost has been increased over standard - they will pour more fuel in as soon as boost is increased, so things get pretty fuelly!
