oil for racing, 30 or 50

Hey guys, im thinking about going down to the drag strip this friday, and
i'll be making at least 5 runs probably. Now I am currently running 10W-30
Mobile1 Synthetic. Im thinking about putting some Valvoline 50W racing
oil, my car has 206000 miles on it (maybe a rebuild at around 100,000 not
sure). Now is it true that running the 50 weight will protect my engine
better (bearings etc.) by being thicker? Just for the same reason you use
70-90 in the rear? Well i hope someone here nows wut im talkign about and
can help!!!

I dont think 50w valvoline will protect your engine as good as mobil 1. Mobil 1 or any good synthetic can withstand more heat, also 50w oil would cause your oil pump to work harder and you would lose some power.

I don't mind loosing alittle power, compared to killing my engine. wut do most people use at the strip?
