GTM TT: Cooling Upgrade Wishlist

Chuck33079 · 08-10-2012, 08:48 AM

With the 34 row GTM oil cooler and CSF radiator, I see oil temps sitting between 195-215 with the ambient temp reading 100-105. Even driving it hard, I've only seen a high of 225. Keep in mind, I'm still running conventional oil since the car only has 7k miles. I expect to see a 5 degree drop in oil temp once I switch to synthetic oil.

The water temp will move from one dot below halfway to two dots above, but the guys at Baker Tuning assured me it's really a 8-9 degree swing in temps due to the water-cooled turbos dumping a lot of heat into the coolant. The temp drops back to normal in about 90 seconds of driving, so I'm not too concerned.

One of these weekends I'll vent the fender liner and ditch the coolant for water and water wetter. Maybe a fan for the oil cooler with a temp sensor before next summer. I'd love a vented hood, but it's a daily driver and Houston experiences some serious rain.
