Glendora Ridge Road is a pretty tough road; it's hard on the brakes and engine, especially on the uphill.
I ran into high engine temps while making a run uphill 17.4 miles on Latigo Canyon Road in Malibu. Oil temp gauge was reading 260. I don't think my Z went into limp mode, but I turned off the A/C and started venting heat into the cabin. The temp eventually dropped back down to about 220.
Anyhow, I'm definitely installing an oil cooler come this spring. After a bit of research, I believe Stillen sells the most affordable bang-for-the-buck oil cooler.
