Didn't wanna rub in the oil temp thing with Chad's problems. 229 was all I hit according to the gauge. Didn't feel like it slowed down really except the heat soak thing when I idled a lot. Went away once I went down the straight.
Edit- again, I have an open top over the engine (doesn't fit with my TMIC) and it was only 55-70*ambient (in the shade, so plus sun). So it should be better now than once it's got aero completed. I wouldn't call it conclusive on my part.
