I'm parked for the winter, it's upgrade/maintenance season!
My 2B does fine most of the time, but I'm struggling to keep the temps under control in harsher conditions. Those situations include idling in traffic on a hot summer day with the AC on, and highway speeds when there's a very slight incline and temps are above maybe 85 °F outside. The worst was pulling a small trailer with a kayak, on a 100 °F day, going 55 mph with the heaters blasting and windows down and still running too hot, I wish I had been going 65 with the AC on. I have my max boost set to 5 PSI and keep my EGTs under 600 °C.
I could probably use a radiator rodding, but if I'm expecting to crank 30% more power out of an engine (someday), while still wanting to use every bit of it, on hot days with the AC running, then it would make sense that I need to upgrade the radiator/fan/fan clutch right? My searches show a lot of posts about overheating, but not many about upgrading. From my searches, the stock 40 series radiator is about 19x17" (329 sq in), some vehicles with the 1HZ have a 22x21" (462 sq in) radiator, and I imagine a boosted 3.4 L IDI isn't too far behind a NA 4.2 IDI as far as cooling needs go.
