[QUOTE="Swiss Boss, post: 14754996, member: 153050"] So after the event with the 10W-40 I switched to 20W-50 and gained 10-15PSI @WOT and switched the front grille to a Saleen. It did help a lot with cooling. Now this winter I installed a air-oil cooler and removed the stock Boss water-oil cooler. I'll do my first track on the 20W-50 that I put in last year then after that I'll switch to 5W-50. Also I did find more info from the Boss302S race car manual. Page 5 [url]http://www.fordracingparts.com/Download/BOSS302SPDFs/Boss%20302S%20owners%20manual%20version%20AV4.pdf[/url] "The Oil pressure should not drop below 30 PSI during normal operating conditions (except hot idle). Oil Temperature should not exceed 300 degrees Fahrenheit." Oil recommended 5W-50 Motorcraft full synthetic or equivalent [/QUOTE]
