Numbers are 456.8 and 478.8 SAE, considering the heat and humidity I was alright with the numbers, this is with my mods in my sig. For the last pull I swapped on the 2.93 and removed the billetflow idler. The 2.80 had a 10-12H/P advantage and 10-15 T/Q advantage all the way to 5000 where the 2.80 held a 4-5 h/p and TQ advantage over the 2.93. Peak gains with the 2.80 were 3.5H/P and 15T/Q. I am gonna try getting the sheets scanned an posting them, A/F was 12.4 -12.5 from 4200-5500 and 12.1 - 12.3 from 5600-6500, what I liked about the A/F is that its as flat as a pancake also keep in mind this is a tailpipe sniffer which is said to be off a 1/2 point so that would put me right where I need to be 11.7-11.9. Rick I will fax these to ya and be in touch, I want you to look over the curves both A/F and numbers wise, and see if you think you can improve on them. Opinons and suggestions welcome.
