No disrespect to Eric, but I have not heard of any other installer that won't guarantee their engines if the factory SPF
oil cooler is hooked up. I think it is so much B.S. and one hell of a sales ploy. Most people report, as does Rob, that the
oil runs TOO cool in most situations. Olthoff Racing (they actually have a road racing background) doesn't suggest that. My memory is that the Olthoff's have done pretty well in the R&G as well as the One Lap. Any problems they encountered were not
oil cooler related. Funny, I don't recall Eric's name in any of these events,hmmm. I also have seen Rob's pieces,which are exquisite. The nice thing is they allow you to regulate the flow to the cooler so the temp can be kept at a high enough temp, which is often overlooked. Too cool of an oil is as detrimental as too hot.
