I removed my super sized heat exchanger and put the stock unit back in. Today I had a track day to measure the results. You may ask why and the answer is 180º IAT's and 245º ECT's while racing with the supercooler. The other reason? To free up enough points to remain in my current class and switch to Hoosiers or like rubber. I haven't looked at my logs yet but can tell you that my IAT's with the supercooler were 20º over ambient and with the stock H/E they range from 25 to 30º over ambient. At 180º IAT's while racing I figured maximum timing was already being pulled so I had little to loose. Glancing at the dashdaq while racing I saw 188º IAT's and wouldn't be surprised if my logs show a little more. My ECT's dropped by 10º on the track. It seems like a success. I'm relieved to see the ECT's come down. I'm relieved to see the PCM doesn't see any difference between IAT's of 180 and 190º. BTW, I set a new personal best today at the track today so what do you think about that? I'll take a look at the logs tomorrow morning.
