Cosworth or Grimmspeed Thermostat

Postby Manplow » Thu Mar 22, 2012 10:16 am

I am just wondering which Thermostat is better to use the Cosworth or the Grimmspeed, i know the Grimmspeed one open when the water's cooler than the Cosworth one but is the water too cool for the standard parts ideal operating temperature with the Grimmspeed one?

They're both very good items and achieve similar results - one of the main differences I've noticed is the Cosworth thermostat seems to have a longer throw in it's mechanism which would possibly give a little bit better flow capability. Whether you'll notice this on the street I'm not sure, but something to note. We've got both on the shelf at the moment so you're more than welcome to check them out in the flesh side by side.
