I'll tell 'ya, when I first heard of these rear-mounted Turbo systems, the whole idea seemed kinda "hokey" to me. But after some more research, these STS rear Turbo kits work surprisingly well and are very well engineered. I don't know specifically about the SRT8 Challenger system, but I've heard nothing but GOOD things about the GM systems. If it's in your budget, go for it and have some positive manifold pressure fun!
