I want to pick out a set of fans and build a shroud to use with my future GT-R project. Can someone with a GT-R measure their fan shroud for me please (height and width)
It seems most use a pair of 12" fans but that leaves a lot of unused area on the shroud that will block flow at higher speeds. I could either add flaps to the unused areas or increase the size of the fans. I would like to possibly use a pair of 14" fans.
Here are the flaps you can use with rectangular holes cut in the shroud. https://www.summitracing.com/int/parts/spu-ix-30130012/overview/
Here is a picture of a GT-R shroud with 12" fans. You can see the unused areas surrounding the fans that will impede the flow through the rad at above 30mph when the fans are not running.. Seems to be about 30%
