Twinscrew would make these cars a monster across the range.

I love the feel of a car with a turbo. However, i'm not sure there will be room for a turbo without major modifications or a different hood. You normally don't see aftermarket turbo kits for american v8 cars, at least not good ones, so I imagine you would need a reputable shop to fabricate a custom turbo set up for you

There are multiple quality kits available for mustangs. I am sure the same players will design a kit for the new car.

Don't forget that STS typically makes rear-mounted turbo kits (twin turbos), so if space under the hood is an issue - it won't matter.

I test drove a 2014 GT, and I'd have to agree. I certainly wouldn't say it's bad, but it's not like a turbo car; even a turbo-4 banger feels punchier at the really low RPMs. Get some revs going though, and it's a different story

He didn't drive a manual with the optional gears most likely. Any more power is unusable off the line, unless you have slicks.I test drove a 2014 GT, and I'd have to agree.

This is true. I drove a GT/CS which probably didn't have the Torsen. I was able to floor it in first from a roll without any traction issues which to me means two things:
1) Not a ton of torque (torque is what breaks traction, not horsepower)
2) Probably not the higher ratio rear-end

I forgot the most important point - you must turnoff traction control. The traction control is very restrictive on these cars. I used to turn off traction control (not the stability control) all the time unless it was wet out.

Nope. Was a manual with track pack (3.73s). Clearly I walked away wanting more.

I think the new Mustang has a lot going for it, I just want instant power delivery.
I don't care about going 170 mph, or really even above 120 for that matter. But my next car will be my daily driver, so I'm really looking for a lot of low end torque for city driving.

Too late now, but see my post above about the traction control. It makes a huge difference unfortunately. I wish the Ford engineers do a little better job with it this time around. It is very intrusive, and I mirror your opinion about it feeling like an economy car with it on.

Yeah traction control was on. The car already has tons of power, I got to push it a bit on Woodword Avenue and once I got past 4,500 rpm it really screamed. I just wish it had that kind of power available without needing to build up some momentum first.
I really don't want to spend the money it takes to purchase and maintain a German car, but right now I think Audi has the right formula. I may be in the minority, but I find the new BMWs to be exceptionally droll. Just very boring interiors and the body style looks the same since the 90s. Audi has a great blend of broad power band and luxury interior - with an appropriately high cost. If I could basically get a mustang to behave similarly on the road with a turbo I'd be really happy; I'd rather have performance over luxury right now.
Personally I've always thought that if you want to go forced induction, buy the model that offers it. Why buy a 5.0 not setup for forced induction when you know there will be a model that offers it out of the box.
That's just my 2cents though.

Just curious if you've driven the Audi's you highlight.
I haven't, but I have driven a BMW 335 (with the twin turbos) and I own a VW GTI. Both have relatively well respected turbo engines, and both make great torque down low, but both also have horrible turbo lag.
I drove the 335 at an AutoX, which admittedly is about the worst case situation for exposing turbo lag, and it was not a fun experience due to the lag. I think if I owned the car I'd adapt to the lag for track driving, but for street driving it is very annoying. The GTI is similar. Less power overall but the lag leaves a similar feeling of unresponsiveness.
The only time I really like the feel of the turbo is when going up a hill. That's when you have high, steady state load at a low RPM, and the turbo really works well in that case. When you have dynamic throttle application, the lag is very evident IMO and masks the low-end torque.
So, IMO, turbos look good on a dyno and provide good advertising numbers, but aren't very fun to drive due to the lag.
I think the positive displacement supercharger that's mounted right on top of the engine with the integral intercooler is a much better way to get the low-end torque. The Audi Supercharged V6 is a good example.
Anyhow, if I wanted to get more low end, with quick response, that's the way I'd be looking.
