it ran 2:02:xx for most of the enduro, which is pretty good.
I ITR cars should be around 1:59:xx to 2:00:xx at thunderhill with the bypass.
SCCA doesn't use the bypass, but I just asked Dave Vodden (track mgr and club racer), who would know better than anyone, what the time difference is. He said easy 1 second, maybe 2 once you get used to the jump, not much more than that.
Okay, so 2 seconds. I predict a well-driven, fully-prepped ITR car will be in the low 2:03s, maybe a high 2:02 take-no-prisoners-track-record-lap going over the cyclone. So, I think a 1:59.xxx with the bypass is very optimistic.
My best so far in my ITR car is 2:05.5 w/o bypass. It still has the original engine but the handling is getting there and I think the driver is pretty decent.
What does that all mean for the S2K? I still say it can do okay at its current weight.
