Ok, I should be headed to the dyno saturday. I'm doing 3 pulls with 15 minutes in between each pull.

I'll be running race gas and ~20psi.

I'm also going to bring a cooler of ice water and a spray bottle to spray on the I/C between pulls to help the fan cool it back down. (seemed like a really good idea to me since I dnot have 70+mph winds to keep it cool)

Basically though, I'm looking for ANYONE that has dynoed with stock injectors and a SAFC. I'd like to get at least a rough estimate of how each % change affected the a/f ratio. Since I get 3 pulls, it'd REALLY help if I at least had some rough idea of if my a/f ratio is 10:1 all the way across what does -5% fuel do to it?

I know every car is different blah blah But it would be nice to have at least a really rough estimate to start with.

Ok, now guess my #'s :D

Been doing 13.2's @ 107mph
