| 80 degrees outside, multiple runs up and down the freeway (at 17# boost). Cooling temps were 5-10 degrees C cooler than with the stock radiator. Koyo quotes 30% better cooling efficiency. Stock: Temperature fluctuated (once idle) between 85 and 90C (185-194F) Koyo: Temperature held at about 80C (176F) +/- a degree. Overall cooling was 5-10 degrees C better (6-11%) More importantly, I'm excited to see how the cooling will be at the July Thunderhill event (July 10 - All Datsun Meet). At the Club Z event a few weeks ago, I had to let off the boost (or go into 5th gear) in the afternoon to keep the temps down. I also made that nose-shroud that some of you saw (check my sig pic - save as and lighten to see it) to keep temps down. After the event, I'll give an update for anyone who cares to read... Thanks, SS
