Good thing about an SC is that power is linear, so you dont get a sudden surge of power like u get when on turbo. It's just like you're running a bigger engine.
Mods are:
Vortech SC (300whp)
Koyorad radiator
Tomioka Oil cooler
Honeycomb front grille

Sounds like you and HRTROB need to get together, being in the same place and all...
With an Ecutek tune you can easily make the turbo setup look exactly the same as a SC if you wanted. There are quite a few on here using per-gear boost control and also ramping up target boost by RPM (what a SC does) because of traction issues.
When I took a look at Doug@TopSpeeds car he has the AWIC which only requires a very small heat exchanger in front, about the size of an oil cooler so it's less of a barrier. I'm not sold on the AWIC system not heat soaking on a track, however they have used AWIC systems for their TT R8 and Gallardo setups with good luck. They were even doing OLOA in the TT R8 earlier this year.
He was using what looked like Inconel heat shielding around the stock radiator fans with his front-facing turbo. I know the stuff isn't cheap, it's like $120 for a 12x12 sheet, but it works very well as a heat barrier.
If people are using 50/50 water and coolant, especially in a hot climate I would change that for a 80/20 or 70/30 blend. Even going to a 70/30 will make a difference.
