Road Racing - what gages would you add??????

i'm wanting to add a couple of autometer gages to the car (2-thats all i have room for) and i'm wondering what you guys would pick for primaraly RR use. i already have fuel pressure and nitrous pressure (i'm a converted dragracer). the nitrous is staying for the all round competition we have here (Texas Triathlon).
i was thinking of adding oil pressure (not sure how accurate the stocker is) and a water temp (i know the stocker sucks ass!). i would like to also have an oil temp (maybee not once i see how hot it gets!!!), but do you guys have any sugestions for any other gages?

Oil pressure with a dummy light for lower than 30 PSI, and a water temp. Get that N2o guage and stick it on the bottle, and add an oil temp in its place. Put a dummy light for more than 220*, and be done with it. If not, just the water temp and oil pressure.
