I 100% agree...you need a shroud.bmA shroud can make a night and day difference in cooling performance. If you want to change fans to improve cooling a shroud would do more than a fan change. The flex fan I showed you would scare me without a shroud!
If you're referring to me, yes I run the OE BB one.you running a shroud??
Flamed64SS, I went thru similar issues. I *thought the fan was correctly buried inside the shroud and it was the right stock fan...radiator was proper etc etc. Turns out that there was too much space between fan blades and shroud. One of our smart forum members figured this out. Runs within spec. now.[/QUOTE
To much space between the shroud and the blades, did you install a larger diameter fan?
