Boost Gauge
Air-Fuel-Ratio Gauge
External Gas Temperature

What other gauges do I need? (I will be racing on tracks and going on long road-trips frequently.)

Finally, what are the average readings for these gauges (eg. 50 PSI, 250 F, etc.)?:
Oil Pressure
Oil Temperature
Water Pressure
Water Temperature
Differential Temperature

Thanks,
