I am not running a alloy radiator... yet. It's still running the standard unit. The sender in the rad. doesn't look like it's been changed recently.

As far as how hot it runs... It's a little strange. I made a 182 mile trip on Sunday in 26c to 30c outside temps and the car ran at a pretty much steady 87c-90c. The temp. would increase some if I went a little crazy with the boost (21/19 Stage 3 MSD chip) , but would fall back to the above temps on normal cruising.
