Nuke VX build thread

[Scott Larson]

Man, some people sure do get testy with a little friendly critiquing! After looking closely at all pictures offered, I would be a little concerned too about not only the percentage of the radiator that your fans cover but also the angle of your shroud face in regards to directing air to the fans. The picture of the Griffin radiator shows fans that cover 75% of the rad surface with a stand-off shroud. The pics of your rad shows fans that look to cover considerably less area and appear to be flat mounted to the rad core. Now, I realize that you have rectified that assumption earlier, but the images do tell a different story. If you are new to the whole custom build thing, it is hard to get used to people second-guessing your every decision, but get used to it; even the pros get second guessed by their peers...Don't take it personally. I wish you the very best of luck with your build and hope you can sort out all the details to your satisfaction and don't stop posting!! (Even if you do take some heat for your decisions.)

...shroud face in regards to directing air to the fans. The picture of the Griffin radiator shows fans that cover 75% of the rad surface with a stand-off shroud.

The math generally works out that ~70% of square radiators can be covered with a round fan, but only ~50-60% can be covered on rectangular radiators. The Griffin picture shows a standard fan/shroud. The Four Wheeler pics are of a "slim line" or low profile fan/shroud. Unfortunately less efficient, but necessary because of the lack of room under the hood. I need to order a vent connector for the upper coolant hose to connect the steam vents from the LS engine and "burp" the system since the hose is higher than the radiator cap. Just a little trapped air just kills the efficiency of the system. Even with all these things the 13 y/o composite/aluminum radiator meant for a aluminum V6 still may not be up the cooling demands of a iron block V8. Only time will tell.

Discussions are fine, but when some says "stick to your guns" - what they are saying is you are wrong. Well, prove it on your end because I have proof on mine. But I'm not above learning from others.
