I am running 50/50 but some people say that it will run cooler with more water?

Yes that's true but with the 50/50 your not risking anything. Useing only water you got some risks.
I run 50/50 cause there not worth it to me .

Water cools better

Actually, water cools better than antifreeze or a water-antifreeze mix. The heat transfer capability of water is over twice as great as that of antifreeze. see http://www.redlineoil.com/content/files/tech/WaterWetter Tech Info.pdf
You do not want to run straight water in your Corvette. If you do, you will need to put in some additives for corrosion protection and lubrication of the water pump.
The higher boiling temperture alluded to in an earlier post comes from the system running under pressure. The water-antifreeze mix has about the same boiling point as water when at about 15 pounds of pressure.
The main benefits of a water-antifreeze mix is corrosion protection, water pump lubrication, and a lower freezing point. Better cooling and higher boiling point are not two of the benefits.

I agree with most of that the exception being that antifreeze does not raise boiling point . It does ,to 265 degrees . read the back of any Prestone container. Water will boil before that even under pressure. ,http://www.newton.dep.anl.gov/askasci/chem03/chem03987.htm ,read for yourself
