Gotta say, its one nice kit! I've had two 112 Radix kits on other vehicles as well as a couple of whipple kits and a procharger (that never got installed). This TVS setup is by far the best engineered and most complete kit I've had my hands on. The install itself wasn't difficult. Very similar to the other 112 Kits I've installed. Maybe 8-10 hours total (by myself) with the compressor going on in just a couple of hours and the rest dealing with the cooling system, accessory bracket, and wiring.
I bought the TVS for my daily driver, which is a new 2008 Silverstone metallic TBSS. I bought the car in December and its only got 600 miles on it so far. This was the first mod I've done to it, but have a few more things planned. It has the stock 3.3" pulley and magnacharger tune loaded (should be good for about 5.5psi). Once I get a few miles on it and some exhaust, I'll pulley down a few notches and see if I can make it dance.
It drives pretty darn good so far. It roasts the tires with stabilitrack turned off and pulls all the way through the shifts. The TVS is very quiet compared to the mp112. You can hear it, but it doesn't yell at you like the mp112. With a louder exhaust, the sound may get washed away.
Once I get a few more runs on it, I'll compare IATs and other logged data from this LS2/TVS combo to my LQ9/MP112. I can already tell you on a 0-85 mph run with 64* outside temps, that IATs only went from 75* to 95* and didn't rise another degree after I let off the throttle. Temps had dropped back to 77* within 30 seconds. Not too shabby.
It doens't look any different than the other TVS installs shown here, but here are a couple of pictures anyway:

Oh yeah, this isn't my first rodeo. I already have a set of Kooks 1 7/8, 3" ORY with a single 3.5" catback, a Phoenix transmission, have a set of Flexalite fans, EFILive, BMR rear bars, Yank 2800, comp 1.75 roller rockers, and a custom cam. I'm gonna wait a few weeks to install that stuff though. I wanted to get a feel for the TVS on a stock vehicle first.

Thanks! I most certainly do plan on getting some times with it. I'd like to get some times with the TVS only then do the other mods I have for it. I've got a new track opening up near me this year. Hopefully it will get completed and opened this spring: www.dallasraceway.com
