another spooling question

[Otto J]

now that we have an idea of timing to help spoolup, what kind of air fuel ratio are you setting during spool up at the line?(launching)

I am at 12.8:1 in my spoolup untill about 8 psi and then drop to 12.5:1 at 4000. My A/F snaps to 13.2:1 at launch for a instant then O2 correction dumps in a little and the car goes 11.8:1 from there. I have been working on the leaner A/F on launch but have not got it perfected, or as perfect as it can ever be to be more precise.

sounds a bit lean to me, my motor likes about 12.5 to 1 during spoolup, but it all depends on the cam combination also

12,5 also
I sure would like to see what will happen when ill drop the timing in that area .I was on the wrong side all the time
