Well, here's what I think I've learned from the data I collected on Tuesday:I'll contribute a window-delete! :clap:
Streets Of Willow is a relatively short, twisty course. There are only two straightaways of any significant length. If you look at the IAT/EGT graphs above, you can see that thermal equilibrium is clearly reached for the "side scoop open" session, and probably reached at the end of the "side scoop blocked" session. While I was still learning SOW CCW, there is no significant difference in laptimes, corner entry speeds, maximum acceleration, or even spark advance between the two sessions. So my guess is that even though the temps are clearly lower with the additional ducting, heat soak is not a significant factor at SOW. I wish I would've been able to gather data at Buttonwillow 13CW, which has much longer, and closely linked, straight sections.
