I talked to a rep from Royal Purple and he said that 180 to 190 F on the oil temp was just fine. So I'm not going to worry about getting the oil hotter than that.

We figured out that the aluminum shavings were coming from inside the oil pump. I sent the pump back to Peterson Fluid Systems and they repaired it under warranty. Thanks to the guys from Peterson for that. The pump didn't have much time on it, but it was well past a normal warranty period since I bought it two years ago.

When I finished this round of testing I didn't think I had anything else to try but after a few weeks of thinking and talking I actually have a fairly long list of things that I'm looking into.

Stepping up to a larger header size with a shorter primary length is #1 on the list. I need to try going richer with the Q16 as well as trying more pan vacuum. Dwayne had some ideas on the heads so those will probably make the trip to his shop at some point.
