I agree with the theory presented, my stumble was the term "high depression", lol, no disrespect for any theory, they keep the mind spinning.

About the new pully...what are your tooth counts now, I got one just before Christmas, running 1:1, giving me about 12 pounds with the 8-71. Bad thing is it's like heroine, I just want more and more.

I use 8mm drive system.
I have a 49 lower 55 upper for 11% underdrive.
The new pulley is 52 upper so it is 5.8 underdrive.
My motor is not strong enough to run any higher. We are going to run side by side tests of this in the spring. I want to see what the real difference is and the effect on the AFR. When I put everything back together I'm adding a data recorder to the AFR.

I get about 6 pounds from 3000 rpm and higher in high gear with the 11 under. I haven't tried the new one yet. I have the car all apart and at the paint shop now.

I managed to make one drive in Dec of about 75 miles in 20 deg weather. Got a little frost on the carb bases. haha
