Turbo muddies the exhaust note. To me the exhaust note is a big experience factor

I think a properly sized turbo for the engine and activity you intend on engaging with will be more versatile and provide a better overall driving experience than a large engine with a positive displacement supercharger will.

The problem is, no one ever seems to want to put a properly sized turbo on their car and the positive displacement guys just love that instantaneous low end torque (I'm not a big fan of that, personally). The thing is, positive displacement superchargers are far less invasive and significantly easier to make it play well with whatever setup you have than a turbo setup. It's largely why there is such a price disparity between the two kits in the aftermarket (quality withstanding).

No one asked but, the turbo on my Audi is hilariously small considering the monsters I've seen out there. But it's huffing out significant amounts of torque by 3k RPM and still pulls comfortably to 7k RPM. I didn't pick anything laggy just to chase top end power and sacrifice street manners, I picked a small turbo that I knew would work well. Yes, the boost levels are much higher than what you'd see in a large displacement V8 and that should surprise no one. But having a ZL1 1LE and also that car, I can tell you which one would put more of a smile on my face, even if I were to take ~300whp away from my Audi and make them evenly powered.

Large V8's with positive displacement superchargers fill a niche and rightfully so. They're brutish and very pleasing to hear as it goes through the gears. The power is very accessible, albeit not always manageable. It is the epitome of what America is and for that, it will always be something people will seek. But if you gave me a choice, I'd pick a turbo every time.

It's more complicated due to routing of plumbing of the hot and cold side, It sounds like to me you made up your mind along time go. Go for it !

[Slippy]

I think wastegates are easier for boost control than pulleys and belts.
Installing a well designed hot side isn't much different than installing long tubes.
Oil scavenge pump is very similar to PD coolant pump.
Installing a FMIC is similar to a heat exchanger.
Pinning a crank or removing crank pulley isn't needed for turbos.
Turbos may need additional heat shielding.
If there's a mistake with turbo boost control, can be a big problem.
FMIC piping can have packing constraints.

Laugh at me all you want, but I'm a chicken and don't want torque to keep climbing fast throughout and beyond the middle of the rev range, hence my choice of a PD supercharger. This way I know that once the tires hook, I will certainly have traction for the rest of the pull or pass (well, okay, I might lose it for a very short while during low gear shifts, but you get the point).

800 rwhp out of a 2.5 L motor (even if it's a built motor running on E85) is quite an achievement, and the TTRS is a pretty light car

I have a Escalade EXT with the 6.2. It’s got 138k miles, much of it highway from prior owners. I have tossed around keeping it and tossing turbos or a supercharger at it. Not looking for monster power or drag strip times. Just looking for some more pep in the whale. Seems like for about $10000, I could twin turbo, boost controller, new water pump, oil pump, lifters and cam installed and tuned. Or about $8000 for supercharger, extra to install and tune. I want to still to be a daily that I can hop in and road trip at 80mph if needed. I keep looking at new 2500hd trucks so just don’t know where I’m going with it yet. The speed shop I called for info and quotes was pushing turbos route but looking around it seems most go with supercharging the platform.

My buddy has one that just sits and sits. I've pleaded with him to sell it to me for years but he refuses.

The guy got himself in trouble and doing a 5 year stint but don't have the heart to ask him now.

I don't think anyone will laugh at you for that at all. A PD blower offers a very predictable power band that can certainly be appreciated. Turbos are all based on engine load and exhaust flow so, you can have a very sudden onset of power but, that's why I'm a firm believer in AWD cars at this point. It largely doesn't matter how the power hits, it'll most likely be ok until you start making retard power.

However, there's a lot to be said about a well-sorted PD RWD car that can put the power down. It'll hit harder than your drunken step father while still maintaining a lot of that momentum up top.

Amazingly fun car to drive, even today.

What's interesting is most AWD cars (high end 911 turbo S and similar notwithstanding) fail to impress on a roadcourse, I thought the M4 xdrive would put up better times (C&D Lightning Lap) then it did (still well behind the ZL1) and Audis are even further back - I guess this is primarily a weight/steering/front end weight bias issue (?)

The GT3 is not getting beat by AWD cars in the price range or even close

Hey, I've had family and friends doing state sponsored vacations. Keeping the "books" funded is one of the most important considerations to our captive brothers. That thing sitting in his driveway while all is good is one thing, that thing sitting in the driveway when he "needs" money is quite another.

Asking him is not in bad taste - compelling him to take less would be.
