On Monday I'm going to check out and FD. The owner has already modified it with a single turbo and the standard supporting mods running 12 psi. Fortunately he installed a A/F gauge which make me feel a little better. My question is what numbers should I see on the gauge? Idell? WOT? Cruising at speed?

Thanks guys

 

Cruising , anything under 16 a/f

idle , between 11-14 a/f

WOT between 12-10 a/f

THis is if the car is not tuned , if its tuned and tuned perfectly it narrows it down a bit .

 

He claims it was tuned by Jeff at rotary power.

 

So how did it go?

 

Test drive at 1 pm. I'll do a report after

 

Those numbers are about right
