You may remember a couple of posts back that I dropped the car off at D-Technique so that they could install the RE-Amemiya oil cooler. I also asked them to fabricate some custom grills to cover both coolers to protect from the odd flying stones and/or insects.The main reason for getting the extra oil cooler was the oil temperature on the track. At Honjyo circuit it was running over 140 degrees after about 7 or 8 minutes and that wasn't even mid summer... Naturally this was not a good thing and something needed doing.
Since the install, I've gone on a 2 day Gymkhana and half day track day at TC1000. The max I saw the oil hit was 110 degrees at the gymkhana which doesn't use the cooler so much as the runs are really short. At TC1000 it was between 100 and 110 for the most part after a hard run so that is encouraging. On a larger circuit like TC2000 or Fuji Speedway, I should have no problems what so ever. The cooler was a tad expensive all in, but will hopefully give my hard working engine a better life and go easier on the oil. So far so good :-)
If I was doing it again, I might just have got the Mazdaspeed cooler as it is smaller and fits more easily. I could probably done the install myself (as no cutting was probably required). I also could have just used the Racing Beat oil cooler grills as-is without having to get ones custom made... Perhaps though the extra cooling will be worth it? I don't know yet :-0
