I knew you guys were doing that. I know Frank has relocated his after he used the front coolers for heat exchangers as well... I was thinknig of just putting the TRD oil cooler on the car, which is a sandwich plate between the block and the filter. It would be nice to have some documented figures before and after the change- specifically at the track since that's where things tend to get the hottest...
Do you guys have any figures? I'd like to know both oil pressure (post coolers) and oil temps (before and after coolers would be nice)....
I had read about a fella with a Celica who actually tracks his GT-S was maintaining temps no higher than 220, but averaged 210 with the TRD cooler and had temps in the 250+ range w/o the cooler. I suspect 220 in our cars would be pretty ideal. Particularly, if we could maintain better oil pressure while doing so... Of course, if this sandwich cooler is so great, why didn't the Lotus engineers take that approach? Tim M would be PO'ed if a guy deviated from Lotus's excellent engineering without good reason

I presume it's possible that Lotus took the approach they did due to cost and availability, as they often were forced to do with other parts on the car.
Best,
Phil
