Your summary is correct.

I plan to run either saturady or next wednesday......weather permitting.

You are correct that when the chiller is ON the heat exchanger is totally bypassed, after it has chilled and got the I/C water to to 55*F or less it has enought there that it holds the cool temp just as good as if it were still on for the time it takes to do a 1/4 mile pass(approx. 30 seconds by the the time you stage the lights and leave). I was very surprised to see that compressor kick back on and stay on from about 4k rpm on, it didn't effrect the number down low but when it kicked on up high you could see a dip (5-10hp) IIRC.

I like the fact that it runs with my A/C on for DD because my runs done the raod ALL day in 100+ weather with 55-65* IATs instead of 110* IAT, I know the dyno didn't show any gain in HP but the car feels snappier than it did, not alot but it feels like it gets through the gears alittle faster than before the chiller.

I would not be so sure that it won't get you more cooling than 40*f on something hotter as it seems the 40-50* mark on my car is about the limit for how cool it can get the IATs, then again it may only get you 40-50*F to, that is one of the things that will differ from car to car and SC brand to brand.
