Here's the slip from my 11.75 run this past weekend...in looking it over, I'm actually *slow* in my second 1/8th mile for some reason? Had I run the same 4.0x second 1/8th mile like I was a few weeks before, I'd have had my 11.6x...not sure if the stiff head wind was to cause, or if I still needed to throw some jet at it?

Actually, the 2nd half numbers look about right to me. If you consider the "rule of thumb" formulas of multiplying your 1/8 mph by 1.25 and your 1/8 e.t. by 1.57, you come up with 117.77 mph and an 11.92 e.t. You bettered both of those figures. As it is, the car gained an actual 23.61 mph on the back half, and that's, as you said, running into a stiff headwind. A typical 10-11 second car will normally gain 23-24 mph on the back half (provided it doesn't have the aerodynamics of a barn door, that is), so I'd say you're covering the back half pretty darned well.
