switching to doghouse cooling system

hi, i had porsche fan setup, nowgoing doghouse [36hp shape housing without outlets at front] does anyone know if the fan inside the fanhousing are all the same. thanks greg

I reckon that there is two or even three different fans to suit dog house style housings. I think the diameter is the same its just the thickness, reckon the later ones are 32mm And the early ones are smaller

Dog house and non dog house have diffent fan widths, where the fan for the dog house setup is wider.
