I installed an 8BA (actually an 8RT)engine into my carrier, so due to the different fan placement, left the shrouds out. The vehicle would overheat after 4 minutes of run time. I sent the rad for cleaning, and used several containers of CLR into my block to try and remove some of the scaling. Re-assembled and it was not that much better. So, using the originals as templates, I made the same thing except with allowance for the new fan position. It made all the difference in the world, and you could tell sitting in the driver's seat that the airflow was many times what I was getting with no shroud.
Engine still runs on the hot side, but I have never had it overheat since. Eventually I will install one of my TL engines, and use the original shrouds, but I'm pretty sure I'll miss the extra 15 hp of the 8BA engine.
