2017 GS - go bolt-on's or supercharge it?
Looking for a possible boost (get it?) in fun. Disregarding factory warranty (but possibly taking account of the performance company’s warranty, if any) which do you guys think is best, slap boltons like midpipe, CAI, pulley, or whatever and enjoy that (getting to what, 500HP atbthe crank from 460) or go for something between 500-600 at the crank via a supercharger setup? Looking for a no hassles thing, where reliability is paramount, with fun a close second.

Edlebrock supercharger if you have to mod...550 or 600 hp in one fell swoop is the smart play.
i wouldnt do headers or any other mod just the basic supercharger kit and a mild tune.
jmo as a guy who did the cam headers gears on his last z06.
the edlebrock supercharger would be the way to go if you really want to go faster...
within the realm of reliable increases but not to far over the top to destroy reliablity,
good luck deciding.
btw before you do that...spend the $200 and get a COW booster...
i bet after that youll see you dont need another mod to have fun..
if im wrong you can return the COW booster for a full refund..,
i did this on my z51 m6 and it was the smart move to increasing the FUN FACTOR..
its really all you need.

Will you track or not track the car? Supercharger can be tracked to 7-8/10ths with not problem but not to the extent of a NA car.

Both boltons and a supercharger? I like my NPP and don't want to lose it (though I leave it on Track all the time anyway, so maybe that's dumb). I was thinking a mid pipe replace to get rid of the back cats and wake it up a bit and then either a supercharger or full boltons. What do people consider full boltons? What can you get away with before you're starting to modify internals? A pulley is still considered a bolton right?

There are a lot of aftermarket axle backs that retain the NPP. For example getting an Akrapovic axle back is less restrictive than the OEM exhaust + is titanium so lots of weight savings. ( Sounds damn great too).
You can do full bolt ons and a supercharger without having to do internals.

Pray IM and TB = $450 w/ core exchange
Pray Ported Heads = $1250 w/ core exchange
Flex Fuel kit = $300
Tuning = $600 for engine tuning (not positive on transmission tuning, or if its needed)
Wheels + Tires = ~$2000 - 2500
2" Headers ARH = $2000 Texas-Speed = $1000
Halltech CAI = $670
So it could be around 6250 - 8500 dollars for a nicely done bolt-on setup. You can lose the wheels and add a DR to your stock wheels, if you so choose. While it seems expensive, its also going to lay down a GREAT base for any future mods, whether or not you want to add a blower or stay NA and add a nasty cam. You can also do it in pieces over time, instead of dropping a single wad of cash on a 7k+ blower system. This is just my opinion, however. I love blowers and turbos, but these cars just get DOWN with simple mods.

I paid 5k for my Procharger kit. Installed it myself. Paid another 500 for a dyno tune for safety. Beat on it like a maniac for 2 years. No problems. 570 wheel hp. Unless you buy some kind of used kit, you won't beat that.

Same here. Installed procharger and catless x pipe. 572 hp at the tires. The car is a blast to drive. Drives like a stock c7 under 3000 rpm but go above that and things start to speed up in a hurry. I recently raced a hellcat from 12-140mph and beat him 5+ lengths. Puts a smile on my face every time I drive it. I have put 24,000 miles on it since installation with zero issues. I also track my car with no side effects from the supercharger. Just had to install larger brakes to slow it down, lol.

It went 10.85@125 before the heads and 10.74@127 after.. Has more in it at that level but have since added ported MSD intake mani and have NW 103mm TB ordered. Car most definitely pulls harder now with the MSD.
Just as an example... here is a video of my buddies 2018 ZL1 1LE with Rotofab CAI vs my na GS. As you can see.. it pulls pretty decent.

Will the Grand Sport trans and differential hold up to a 200 horsepower increase? Does it have the same drivetrain as the Z06 or is it the same as the base corvette since the Grand Sport and the base vette have the same horsepower? I have a 2017 Grand Sport with a manual trans and may want to add a supercharger in the future.

My 2017 GS with boltons and Pray Performance ported OEM Heads/Intake Mani/TB made 508rwhp. 489rwhp before the ported heads. Flex fuel tune by Pray Performance on E85.
It went 10.85@125 before the heads and 10.74@127 after.. Has more in it at that level but have since added ported MSD intake mani and have NW 103mm TB ordered. Car most definitely pulls harder now with the MSD.
