Keep in mind I'm bumping up against t-stat temp. At freeway speeds before I was cruising at between 93-96 C depending on traffic. I'm now somewhere between 90-92 C. T-stat is likely slowing flow so these "tests" aren't the best at showing what is really happening; however, it is what I am capable of doing right now.

No shroud for me. SPAL fans on fan rings. The OEM unit is the best fan shroud I've seen to date. Everything available on market is bent sheet metal with stronger fans, which is not better, just more airflow from higher output fans.
Fan shrouds/fans will only be useful at lower road speeds (sub 30MPH), and if they are helpful at higher speeds than that, something is not setup correctly in the system.
Think about it for a second; fan shrouds actually block airflow at high speeds; increasing drag and reducing performance.

Vertical band saw. You can also use sheet metal shears. There is no reason someone can't get a bit creative on their own and make something similar for very minimal costs in tools.
Forgot, another prototype out of the printer. Final revised AOS.
Thanks,
