Engine baseline of 178/dual cai/fuel regulator.
I got the scans of the two charts showing the weather and power put down with the srt last Saturday. This will be my baseline for further testing. Ill annotate it more in the next few hours. The F/a curve is the first attempt at my tune, more is to be done, Ill elaborate more. Woody. Conditions are at the bottom of the charts, I was not happy with the results but they are what they are, No bull here.
BTW, this is the factory tune currently.

12.1-12.5 looks good to me. makes me feel safer running without a tune and the same setup. we have the same MPH ET is mostly just tires and track prep.

At twenty pounds of boost I was running very lean, the fuel controller I have written about is in and working to control the a/f dynamically. Its not proven yet and still an engineering exercise as yet. WW

Re: Engine baseline of 178/dual cai/fuel regulator.
When I ran on the dyno-jet, it was refreshing to see the same H/P ratings as the other; Mustang Dyno.
THe torque showed a drop in power near 5000 which I attribute to being TOO rich at that point. The DA was down a bit due to the rainy day, but the boost still hit like 20 PSIG. There were a total of 9 pulls getting the Dyno to consistantly read the plug wire signal, all were similar in shape. Heat did not seem to be a problem as 4 runs on the inerta wheels were done in a row!, in rapid succession. This was to trouble shoot the dyno hook up, everything stayed together nicely.
My next runs on the DYNO are to be with "Non-April 1st" better manifolds and a bigger pulley to see if I can get a real gains in (dyno) power.
Stay tuned, same Bat channel....
Woody Enjoy
Because the dyno is a reaction wheel style, the torque at the bottom end was not indicated as it was done from a roll, to limit spinning of the tires. Pulls were in 4th gear, though I have had and heard of 3rd gear pulls. Not sure it makes a difference, that is noticable.
