What a perfect A/F ratio for an turbo set up ???
 

Had a t3/t04 turbo with an 02 wideband hook up and the VAFC . I'm going to tune the car for fuel ratio and dont know what is an perfect number for 1k-8k rpm. Could anyone give me a clue what is the ok fuel ratio to set at from those RPM???
I heard people said about 14 right?

12

on most cars I tune to 12:1 air fuel. Provided you have a correctly set up car, that should work for you as well.

on a stock b16a2, with a t3/t04b turbo(intercooled), what would you keep the timing around from 5-8k running at around 10psi? Also, the car will be running plugs that are 1 step colder.

If you need more info, just ask. I have no idea what other info I should give you.

But please remember that air-to fuel is only half the story of what is going on. dont be fooled with the "I have perfect AFR and my car will be perfect" myth. Timing is what you should be looking at.

I had a drag t3/t04 turbo. I was using the VAFC hack to tune my car with my o2 sensor, 440cc injector. I dont know what precise the A/F ratio to be correct running about 8psi of boost, stock internal.

And for Timing, was it necessary? I mean for 8psi of boost I dont think it needed. Am I correct? or I need a MSD 6BTM ?? for better run?

Any more tips appreciated guys.
