[QUOTE="Jimmysidecarr, post: 5556266, member: 11681"] "Necessary"??? for some maybe yes. for others certainly not. Each rib of each vent has it's own low pressure area at the base... the air rushing over pulls more air out of the engine bay dropping the pressure behind the rad. Lower pressure behind the rad = more air through the rad. "Necessary" is kind of relative to the end usage. It will not be necessary for many... but it will be interesting to see the results of this experiment... since we know open track does overwhelm the cooling system on these cars on many occassions... in many different areas and climates. And we have seen that fat radiators often do not do a whole lot by themselves... unless we can get more air though them. A larger radiator will by itself reduce the cooling air flow [SIZE="4"][B][I][U]with the existing inlets, vents, and air dams.[/U][/I][/B][/SIZE] It does this because it is more of a restriction to air flow than the thinner stocker. So basically a larger radiator without attention to some sort of air flow increase may produce results that are somewhat less than we had desired. [/QUOTE]
