Race Day!

I think I need to work on my nitrous/fuel mixture. No bottle heater with a high temp today of 50 degrees. Fuel pressure 8 psi. My Edelbrock nitrous manual says jet sizes based on 5.5 psi. Had about 6.5 last year when I ran the 12.76 on street tires.
There is a test and tune tomorrow. I plan to set fuel pressure at 7psi and timing retard at 4 degrees (set at 5 degrees today). Hopefully these changes will help my time and mph a little.
I took several pics, will post them soon.
