3 weeks ago at Road America I noticed my water temperatures were about 2/3s (late dash) and my oil pressures were between 2 and 2.5 sometimes which made me nervious enough to pit and check things. I bought some DEI Header wrap and wrapped the front and rear headers. I also used DEI cool tape on the fuel lines which cross over the 3 header in my car.
I was back at Road America this weekend racing with SCCA. The water temperaturs were about 1/3 in more or less similar driving conditions and the oil pressure was around 3 mostly so the tape looks to definitely improve things.
