That’s my thinking on both counts. I was absolutely prepared to add the T-stat if warm up times took much longer after installing the 925 Setrab. Didn’t notice any problems with longer warm up times even when it’s in the 30s or 40s out.So with the OEM water/oil cooler in place, is an oil cooler thermostat really doing much to help speed oil warm up times? I'm running the OEM water/oil cooler + the Improved Racing remote filter mount w/ 185* thermostat + a Setrab 948. If getting engine oil temps up quickly with the OEM cooler in place is sufficient then going to a remote mount without the thermostat (http://www.improvedracing.com/oil-c...gine-transmission-oil-filter-mount-p-830.html) would remove a couple oil lines, tidy up the install and probably result in better flow/reduced pressure drop?
