Just added N20..10's here I come!

I had my timing @ 12-13 degrees with the 150 shot. I also only sprayed it when the engine was fairly cool. Never above 170 water temp.

I hope you have better luck than I did. While running 112 mph on motor my best pass was 11.1 @ 122. I did trap 125 at a different track though. I think you should see somewhere around 10.7-10.9's around 125.

good luck, and post the results as soon as you get them!
