You need a shroud. That is a damn good radiator you have but air is blowing all over the place under the hood. It needs to be aimed towards the engine. The e-fans never worked very well for me so I went with mechanical fan but if you just don't have the room then you don't have room. Mopar just didnt allow much room for thicker radiators that is for sure. I don't think they ever figured it needed to be thicker. lol
