I am using the Toy Jet system. I really wish a couple of LS guys could let me know what their temps are when at high rpms. Even the guys with tall gears when they drive down the road in a lower gear at 4000 - what are their temps on the LS temp sensor (factory installed)... for front and rear radiators. I have a good sized radiator and by math it should do the cooling. I am not sure that the LS motors were meant for high rpms and therefore the real answer is tall gears or a larger radiator...
