Hello Folks,
Today I completed the installation and testing of my Mattson's Custom Radiator cooling module. I am very happy with the product and the results, and although it was a bit spendy, I feel the quality and workmanship justified the cost.
My engine is a Blueprint 383 stroker (420HP/490T). The previous owner, who had a 'dragstrip' mentality, 'deleted' the thermostat, and my previous radiator/fan was set to come on somewhere 175 degrees, as my temp gauge never got above 180.
When I changed out the radiator I also installed a 180 degree thermostat. Mattson's provided me with a 195 degree fan sensor (the module came with a Spal fan controller with two options, 185 and 195 and it would appear that based on my setup Mattsons decided that the 195 was more appropriate, as they never asked if I had a preference). With the current setup my temp gauge will spike to around 195 before the fans come on, but will then drop quickly to about 180 before shutting off.
At first I was concerned but I have to admit the the engine is running great, no pre-ignition at all and I get the feeling that the engine is running more efficiently, as the exhaust fumes are less intense than before.
Question for the group...I'm thinking that my old setup was too cold, but I'm wondering if the 195 switch may be too warm; would a 185 switch be more appropriate for my setup?
Thanks in advance.
