In the late 80's I used to build and race small block Chevrolet street/drag motors, and one of the "tricks" we had to keep things either cool or within a specific range was to drill a hole between 1/8 and 1/4 in the t-stat plate. This allowed some coolant flow before temps reached the opening point, and it allowed the t-stat to flow more coolant when open. As well, another argument was that it reduced pressures againt the water pump when the t-stat was closed, reducing pressure and wear on the seals and bearings.
Thoughts on this mod for the Boxster???
