Spal Fan Upgrade - ZR-1 Net Registry Forums

secondchance · 06-03-2019

I know a few already modified their Zs with Spal fan for cooling improvement. I finally pulled the trigger and decided to follow suit now that I am running a 200 amp alternator to back them up.
Once I received the Spal fans I found out the outside diameter of Span fans to be an exact match for inside diameter of OEM fan housing. So, instead of using the Spal fan housing and having to deal with relocation of AC dryer, I chose to transplant Span fan to OEM housing.

Spal fans hacked off of stock housing/panel.
took some nerve to cut up a brand new $365 part.

Test fit.

Almost ready to go.

OEM fan housing is internally divided into two sections served by one fan each. I am cutting these back so that both fans will serve the entire radiator. Also, two openings on the OEM fan housing will be closed off to increase efficiency when fans are running.

Can't wait for 100 degree day just to see how it performs.
