12a turbo, 15 psi, streetport, basically stock internals, OER sidedraft, 3.5 in exhaust, GT35R stage V (Turblown.net), custom mani (Turblown.net). 8000Rpm redline

What kind of AFRs and EGTs should I be running Throughout the rpm range? My Egt probes will be in the mani on front and rear runner?

 

what kind of fuel?

 

91 octane pump gas

 

Probably about 11.1 at 15 psi 11.5 at 10 psi and 12 at 2 psi. Taper it inbetween those levels. Egts around 1600 - 1650. Keep
your air temps as low as possible, and aux injection is everyones friend

 

thanks!

 

those are good guidelines. you can also play with the AFR and timing some. Some like to run a little more fuel (richer) with a little more timing. I prefer a little less fuel (mid 11's AFR) with less aggressive timing advance. Every engine is different.
