Stay NA or go to the Dark Side?

So I didn't want to create a new thread on this, so I'm raising this one from the dead. I have a lot of new questions to ask...

After looking at Staples results on his Stage II on meth, it got me thinking. What is the weak link on the our stock bottom motor? I was thinking pistons. And what was the 550whp limiter that came up to this "max" number? I know torque was a big factor, but I saw that as more of an impact on drivetrain. I was looking around on here for a couple hours and couldn't find the concrete answer I was searching for.

Now here is the second part of the question. If high octane (E85) and meth injection prevent detonation, why do I only see meth injection as the defacto way of doing things? Why has there not been a FI'd E85 running stock guts or compression? Hell, is it possible to tune the motor to use both?

I'm still going back and forth on what I want to do, but it's coming down to BP's kit and the GTM twin SC kit. They are both very different from each other. I know that no matter which way I slice it, the turbo will make more hp and tq in the middle of the power band and at lower boost pressures. But this is what my concerns are and it's not the kit, but my environment. It routinely breaks 100 in Las Vegas, I would say for 1/4 the year is over 100 degrees. The turbo is going to put a higher heat load for the oil cooler and radiator to dissipate. I will be upgrading the stock radiator with what ever I choose to do, even stick to NA, it's just the smart thing to do. I don't know how much overhead is in my system and I don't want hot weather to impede on my fun button on the floor. My headers, intake and Y pipe all have to be removed and sold. Yes money back in my pocket, but it's a PITA to sell things, and even a bigger PITA to remove the headers. There are a lot of exhaust changes to make it happen. I think the whole system is top notch and a much larger value than any FI product available.

The twin supercharger packaging allows me to keep everything off my headers the same. And I still have the choice to run with or without a cat. The motor still keeps it's stock characteristics, but with a lot more go. I wouldn't have bought the car if I didn't like the motor and how it build power. The Rotrex SC's are pretty awesome. They basically have a mini CVT. They have their own oil cooler. There is no additional load from them on my existing oil cooler and it can just work on keeping motor oil cool. Again radiator will be upgraded and with the whole front end coming off for the install, that makes things super easy. The torque doesn't go anywhere but up, almost like the hp curve, and the motor doesn't stop making power until redline. No flat spots, no dips, just smooth power. With wanting to jump into some track events on occasion, I think the supercharger might be the better way to go.

Lastly, does it make sense for me to run E85 instead of meth or have ability to run both depending on fuel? I'm looking at this as a cooling and reliability standpoint. I don't know how meth/water is tuned or if it can be turned off with a map change. Can't help but think about the benefits these have with the hot weather and elevation.

I know I asked a bunch of questions and appreciate the help. My Wife is on board with everything. She is taking the car in December for an oil change, spark plug change, resonator install, a M370 reinstall, tune check and some dyno passes with the resonator and HFC. I'm hoping the cooler weather will give me a more accurate look at my baseline and untuned numbers from Feb and March earlier this year. These are the last round of mods before she goes dormant till I get home. Thanks all in advance for the help
