I mean in drag racing you "might" be pushing it for a minute at a time, and heat build up isn't a concern, but when you're out on a road course for a 20 minute lapping session this becomes much more of a concern. I can just imaging the turbine side of a turbo glowing red hot, burning up the oil in the turbo, bearings siezing, and car going caput.

From what I understand you want as much exhaust heat (and consequently exhaust velocity) to go through a turbo as you can get. So having a hotter exhaust temp, as long as the piping/turbo can handle it is a good thing. Then just intercool the intake charge with an effecient turbo/piping and you're good to go.

And there are methods of getting rid of the extra heat. But like belts breaking on super chargers, you need to be aware of it so you can make educated decisions about which system you buy, and try to build it so you don't have issues.
One plus of using an LSx motor is it has a composite intake, so you don't have that heat soak issue that people deal with on other motors with metal intakes.

You better look at the rear end catalog Don has. That's going to throw down Pro Stock level torque.

If you can handle the extra 1/4 sec of lag in the spool up, you can mount the turbo in the rear & ventilate it. Not that I like how low an STS hangs, but at least all that extra heat isn't in the engine compartment. The heat + how much harder it is to make a turbo install 'show quality' is why I went with a super charger.
But both make great power, and have issues to work out, AND cost a lot of $!
