what i have done to get the temps down, is very simple,, Rob at Needswings was a great help in getting this done ,and you too can have your own system, Rob told me he would make this system but only on a build on order only , two heat exchangers ,one behind each fog light (fog light removed of course) here is the video of my car after hours of hard running, the temp as you can see is 71* don't forget this was with my sl55 with no inlet tubes on it just engine bay air,,, you can see boost ,,rpm,,speed, water temp IAT and spark adv. jim
