Hey Greg,
It was nice to meet you with David today at lunch.
took the test, not to brag but I got 8/10
I'd like to hear more about he surfactant qualities of oil and how varying pressure and tempreratures effect power output.
I have a 427 cubic inch SB Ford in my Cobra Replica and I run a Canton 8 qt road-race pan....I notice when running the car it will take quite a while for the oil temp (temp pick up in the sump) to exceed the coolant temp (motor runs 185-190 coolant on a hot day and oil can reach 225-230).
I don't really road race the car, just for fun but i'ver considered putting on an external cooler...the issue is not the oil running too hot, it's more that once oil gets hot it tends to stay hot and the harder you run the motor the more head can build up in the oil system.
When I drag race my various cars I always try to get the oil temp up to around 130...not sure if this is a majic number but it seems to work well in terms of minimizing both friction and wear as evidenced through tear-down inspection of components.
I also have a modestly tweaked LS2 in my 06 Trailblazer SS, the coolant temp runsabout 210 on this and though I've used Mobil 1 exclusively I've had good results with AMSoil in crankcases and rear differentials. My Cobra has a Tremec 5 speed and I've been advised by many racers that GM syncromesh is still the best thing to use... I do know that with Synchronized gears too slick of a gear oil can actually increase the loading on the gears by allowing the synchros to spin too quickly during gear changes, resulting in tooth wear similar to an oil that doesn't allow them to engage quickly enough.... any comments from your expereince?
