Josh, I have a ProCharger in my 2013 V6 Performance Pac Mustang. In that application, forced induction plus V6 is a great combination. In my case, I don't think my clutch is quite as strong as the one in the GT. But a clutch is reasonably inexpensive. The manual transmission in the V6 Mustang is the same as the GT, except the first and second gears are a bit lower in the tranny they put behind the V6. I have an aluminum drive shaft, also.
I really wish someone had made a screw type SC for the Ford 3.7 back when I did the Mustang. But they say there's no room under the hood for it. The Ford V6 responds very well to the Pro Charger. Boost on my car starts at about 2800 rpm. But it revs to 7000 rpm, so it's not hard at all to keep my car in boost if I want.
Forza did the work on my car. I'm pretty sure there are pics, and a little review that I submitted, still on their site. My car is in a mild state of tune, which is what I asked for. But it's still pretty quick. It weighs 3560 pounds and puts 393 hp to the rear wheels. If I stay below 2800 rpm, the car gets even better gas mileage. I've gotten 32 mpg. Like I said FI V6s are a great idea.
Like you said, don't beat on it mercilessly and you'll have a lot of fun for a long time. If need be, there are worse things than having to replace a tranny, if it comes to that.
