I mount data temp sensors within a few inches of the factory temp sensor.. so I have other info coming in. I regular see 205-215 in 2.5 race cars with 3rd radiator. The BoxsterS cars with the 3.2 will go 220 all day (but read a nice steady 195 on the gauge)

The 987's are even worse
Interesting. Do you have experience with UDPs in terms of impact on coolant temps? Guessing a lot of the 2.5 race cars have UDPs and if coolant temps was a problem would the stock pulley be better or does it even matter? Thanks.
